Weiss Engineering AFI1

AFI1 Firewire to/from AES/EBU and ADAT Interface.

The AFI1 is a 24 channel Firewire Interface with 8 channels of bidirectional AES/EBU interfaces and 16 channels of bidirectional ADAT interfaces.

The AFI1 simultaneously supports the following conversions:

  • Firewire to AES/EBU (8 channels)
  • AES/EBU to Firewire (8 channels)
  • Firewire to ADAT ( 16 channels max.)
  • ADAT to Firewire ( 16 channels max.)

Features of the AFI1:

Inputs: Digital Audio inputs on Firewire (two connectors), XLR (AES/EBU), Toslink (ADAT, two connectors).

Outputs: Digital Audio outputs on Firewire (two connectors), XLR (AES/EBU), Toslink (ADAT, two connectors).

Sampling Rates: 44.1, 48, 88.2, 96, 176.4, 192 kHz. Number of ADAT channels at 44.1/48: 16, at 88.2/96: 8, at 176.4/192: 4.

Software: Drivers for Windows™ and OSX™ operating systems.

Power Supply: Supply range: 100..240V. Power consumption 10VA max.

Our first AFI1 arrived studio last week. When we open the box, usual swiss made high quality finishing and metal works, although not as exotics as the consumer audiophile thick anodized aluminum. The panel is minimal with just 3 LEDs – (1) Power (2) IEEE1394 and (3) Sync

AFI1 does not work only under IEEE1394 bus power, it needs AC Power connections. This is expected from highly regard as the highest end professional audio manufacturer. Setup is easy, install the software on PC or Mac, hook up the firewire cable and starts working.

The manual does not includes all information that you will want to know. It just shows you 2 screenshots (P.7-Mac/ P.8-PC) without telling you what those options are. But if you check out the DAC2/Minerva manuals, you will see the coverage. I’m sure Daniel will add those back on AFI1 manual soon.

Software selections:

Available Devices: You can view a list of available device, if you have more than one AFI1

Master Device: You pick the Master Device, all other device will be sync to this Master Device Clock

Clock Source: You can select Internal, any pair of digital inputs or Wordclock input.

Isochronous Buffering – Machine Type:

This works only under MAC OS/X – There are 3 options here (1) Slow (2) Normal (3) DAW. This determines the latency/buffer in 3 separate settings. While DAW gives lowest latency, it demands the most from computer performance. The minimum roundtrip latency with an AFI1 was about 6.5ms, with the buffer delay in the application on the Mac which loops the audio minimized.

Windows Panel:

  • Master: If you have more than one device, here select which device to act as Master
  • Sample Rate: Current working sampling rate
  • Sync Source: Internal / AES input
  • Buffer Size In Samples: Larger buffer sizes increase robustness against dropouts, lower buffer sizes provide low latency.
  • Operation Mode: determines the stability of the system. For weak systems you should select Safe Mode Level 3. For lower latency Normal or Save Mode Level 1 can be selected.
  • Buffer Size In Samples: Larger buffer sizes increase robustness against dropouts, lower buffer sizes provide low latency.

Software upgrade wish:

The biggest different that I find between Weiss AFI1 and other soundcard GUI is, Weiss AFI1 does not provide any metering. This is a headache when we connect all cables and hear no sound. We have no way to see if the Weiss AFI1 is functioning or having wrong patching or routing under sound panel. I do wish there will be a software upgrade that allow us to see a metering on all 24 channels inputs / outputs. Of course it will be better if we can assign select channels to multiple outputs, plus hardware mixing feature. The software compares to Lynx or RME mixer is too minimal. I will strongly suggest at least a level meter on I/O. TCD2220 supports this on hardware level. Maybe Weiss wants to release a firewire based hardware 24ch I/O meter pack to chain with AFI1. However a simple software meter within Weiss panel will help a lot.

Well, in audiophile terms, the less function, the better sounding. How about the sound of AFI1?

Sound Quality

The best I heard from any sound card, period. First of all our mastering studio have all jitter-immune DACs from terrific Weiss DAC1-Mk2, dCS 954 and Crookwood Mastering Console DAC. We have both Mac and PC sound interface from RME digiface, Lynx AES16SRC, firewire devices MetricHalo 2D Expanded 2882 +DSP, ULN2 etc. I can proudly say jitter is not a concern here in our mastering room. However, I still feel that the sound from AFI1 is superior, especially in high sampling rate high resolution materials. To avoid goes into digital audio Vodoo, I will just want to have AFI1 in all my production from now on. The feeling is similar to last time when we hook up a Weiss Hydra-C between CD transport and DAC. ** Hydra-C and AFI1 uses completely different dejittering solution although they are both based on dual PLL scheme – jitter is suppressed in two stages. **

When almost 100% of all today recordings (even Vinyl!!) are made by DAW (digital audio workstation), there is no reason why using computer as source sounds inferior than CD transports. The historical audiophile digital myth will be out soon, if not already out. When looking at today digital media, all DVD-A, SACDs, Blu-ray disc, are not as effective and good as music file.

Weiss AFI1 is the ultimate bridge between computer and music playback/recording.

    Hello Mani,

    We can be called as Weiss asia center, and I would more prefer to provide end user perspective for people.

    Weiss just did a software update which supports dual wire at 176.4 or 192. The new AFI1 units will have DIP switches at the back where that mode is selectable.

    11 September

    Thanks for the confirmation – I have been waiting for such a product from Weiss for a long time… in order to replace my RME FF800 in my stereo hifi.

    I will be ordering my AFI1 from the UK distributor this week.

    Thanks again.

    Hello from france.

    Can i use the AFTI1 like interface with my Mac book and record a session in logic audio.
    I have some focusrite préamp ( isa 428 X 2 ) . so i can use adat output directly in the AFTI1, and use Firewire in my macbook ?
    Sorry about my poor english.
    cause i have goods preamp I’m just looking for a good interface compatible with Mac os 10 and logic audio.


  6. admin

    7 October

    Hello TESH,

    AFI1 is exactly the interface for computer recording/playback. Yes you can connect the ISA428 ADAT outputs to the AFI1 and use firewire connection to the macbook. The AFI1 will act as a soundcard with 16 channels ADAT input soundcard under Macbook sound device.

    “AFI1 was about 6.5ms,” How did this compare to your metric halo/fireface interms of latency?


  8. admin

    13 October

    Hello Randy,
    I never worry about the latency of the MetricHalo 2882 or ULN2, however they just provide stereo AES I/O which is not enough for me. We have 1 x 2882 Enhanced and 2 x ULN2, under Leopard aggressive device setting to combine as 6 channels AES I/O.

    Can this output two-channel digital into DACs?

  10. admin

    10 November

    Yes. It has 4 AES/EBU input and outputs. Not only it can output two-channel to DACs, you can output 6 channels AES output for movie playback if you have software decoder and 3 x stereo DACs.

    Hi Be4,

    It depends on what kind of application that you would like to use in how low latency status. I have a Powerbook PB17 1GHz and it works fine for 8 tracks 24bit/44.kHz mixing.

    is there any difference btw Weiss Vesta & Weiss AFI1 (other than the number of channels)?

    • admin

      19 January

      Weiss Vesta is aimed for high end consumer who has a very high quality external DAC. The basic structure between AFI1 and Vesta are the same. The AFI1 is a professional 19″ rack mount unit (8 channels AES/EBU plus 16 channels A-DAT I/O).
      Vesta is stereo only and has an audiophile grade thick anodized aluminum front plate with just half rack size.

    Hi Kent,

    I would like to use the either the Weiss Vesta or the AFI1 (fed by Macbook Pro via Firewire) to feed my Esoteric D03 DAC for 2 channel audio playback. I also have an Esoteric G0s master clock and it appears that the AFI1 has an BNC connector which would allow me to connect the word clock to both the AFi1 and the D03 dac. It does not appear that the Vesta has this word clock input. Also, the Esoteric D03 dac produces its best sound via dual AES/EBU digital inputs. In reading the Vesta manual, it talks about a jumper switch that allows dual AES/EBU digital output, but it seems that one channel is output on an XLR connector and the other channel would come out on an RCA connector – is this correct? If so, I don’t think the D03 dac would accept this form of dual AES/EBU. If you use the AFI1 (with the dip switches) to get dual AES/EBU – does the output come out on 2 XLR connected digital cables? Also, in your opinion, which of these products sounds better – the Vesta or AFI1 or do they sound the same? Any input would be greatly appreciated. Thanks very much – Arnie

    • admin

      30 January

      hello babybear, sorry for the late reply. We are too busy on the AJP III as it receives worldwide attention after the CES show. I suggest you use AFI1 as it perfectly fits what you want. The Vesta has no BNC wordclock input, although it allows you to use AES or Coaxial as external sync.

      AFI1 has both WordClock I/O, supports dual AES, and more channels. They sound the same but AFI1 feature is more suitable for your usage.

    Hi Kent,

    when setting up software selections for a music library consisting of 16/44, 24/96 & 24/176 file formats, what sampling rate should one select?
    are files in non-native sample rate (as what was choosen in the software selection) be up or downsampled by the computer &/or AFI1?

    • admin

      4 February

      Hello flat6, bitrate doesn’t matter. AFI1 will always use 24bit. For sampling rate, if you are using Windows, AFI1 ASIO driver can automatically switch sampling rate fits with your source, so that is not an issue too. If you are using MAC, (e.g. itunes) the current case is if you set the AFI1 as 96kHz, all other sampling rates will be SRC to 96kHz by the software (iTunes). This is not the most transparent method.

      This is a reason why Sonic Amarra gets very positive feature that can use the iTunes GUI in selecting songs, but with its own playback engine, which automatically switch sampling rate to fit with the source.

    First of all, thank you for this very usefull page about the Weiss. This is my question :
    I have a Merging Sphynx (sure you know that gear) with 8 in/out AD/DA on XLR and 8 IN/Out on AES/EBU + 2xadat in et 2 adat out. I work with protool (digi 02) directly with the ADAT in. Can I plug the Sphynx directly in the Weiss AFI1 and the weiss in my MACMINI 2ghz via Firewire ? so I could be abble to work with other software than protools.



    • admin

      4 February

      Hello Benoit, of course you can.
      If the Sphynx output both 8 x AES/EBU & 2 x ADAT at the same time, you can hook it up with AFI1 I/O.
      Your MacMini can run a second program to capture or playback.

      The Merging Sphynx will act as a front end AD/DA for both Protools or MacMini, by selecting the I/O between ADAT or AES.

    Thank you for your answer.

    Just another question, I record essentially acoustic instruments (Violin, classical nylon guitar, oboe, clarinet), to your opinion what would actually be the most transparent software I can use ?

  19. admin

    4 February

    That depends on if you are using the software algorithms. (EQ, Compress, Reverb).
    Do you sell you music in your region, let’s talk and see if we can collaboration. We have good audiophiles in my regions that always looking for good sounding acoustic stuffs.

    I use WaveLab and like it the most because I do not use any processing. The Bit rate meter tells me that my content has not change input and output.

    I’d like to use the AFI1 with a CD transport, not a PC. The reason is that I want to slave the transport to the DAC, which I can’t do directly because the transport doesn’t have an Word Clock input. I’d like to know if the AFI1 could be used without a PC, just as a standalone AES/EBU to AES/EBU pass-through interface between the transport and the DAC and slave the AFI1 to the DAC instead of the transport.

    If it needs to be configured through the PC software (like selecting the Clock source), after it has been configured does it still need to be connected to a PC or can it be disconnected and work as a standalone device until you want to change the settings?

  22. admin

    19 March

    Hello Alex,
    You can use AFI to slave to external sync (wordclock) or AES input. AFI1 keeps the setting when no firewire is attached. However since your source (CD transport) cannot be sync with the master clock, I think it is better to have a transport which accepts external sync. By this theory I think using a PC or MAC playbacks will be superior.

  23. Alex

    19 March

    Hi Kent,

    I’d like to use the AFI1 with the new PS Audio Perfect Wave Transport, which will be able to read WAV files up to 32bit/192kHz. Unfortunately they didn’t include an Word Clock input in it. I’m thinking that by using the AFI1 between the PWT and a DAC with an Word Clock output, I’ll be able to decouple the PWT from the DAC; the PWT already is a very low jitter transport, but in the conversion process the best way is for the DAC to be the Master Clock and not to have to extract the Clock from the AES/EBU or SPDIF stream. Would a digital chain like PWT-AFI1-DAC not work because the PWT can’t be synced to the master clock?

    My thought was that the AFI1 could work in the same way as a HYDRA. I would have used the HYDRA but it doesn’t have an Word Clok input. Maybe Daniel could come up with a HYDRA that accepts a single wire 24bit/192kHz AES/EBU stream and have an Word Clock Input.

    BTW, do you know of any Pro CD/DVD players with Word Clock inputs on them? I know of HHB CDR882 and Tascam DV-RA1000HD recorders, but maybe there are others out there…

  24. Hello everybody, excuseme my bad english, I can use the AFI-1 in a MacPro (runnig Windows)with SEQUOIA software?

    Not to get off the track of this thread, but I am considering purchasing the AFI1 or the new INT202 Firewire interface to link my MacBook Pro to a Bryston BDA-1 DAC. I am trying to get some recommendations for what folks consider an excellent to outstanding AES/EBU cable to link the AFI1 or INT202 to the Bryston. I know Nordost, Kimber and Cardas market AES/EBU cables, but not sure which of these or alternatively other brands are the best.

  36. irb

    26 September

    Hi, I’m thinking of using a Weiss AFI1 as an interface between a PC and a dCS Delius. The advantage of the AFI1 over an INT202 in this situation is the wordclock input, allowing the AFI1 to be slaved to the dac, which would be the master. I’d be using dual AES wires.

    However the dCS only outputs a 44.1kHz or 48kHz clock. What happens if you are playing high res files? Can the AFI1 multiply the clock frequency being delivered to the wordclock in? For example, will it play a 176.4kHz file correctly if the AFI1 is slaved to a 44.1 clock source?

    Any advice would be appreciated.

    • admin

      27 September

      Hello irb,

      It is very usual that AFI1 becomes the standard for dCS Delius/Elgar user in computer audio playback, because of DualAES and WLK input/output as you explain. When playing HiRes, you will be using AFI1 as master clock instead. AFI1 will not alternate the clock frequency from WLK input.


  37. Jirka

    14 February

    is possible use AFI1 as a ADAT TO AES/EBU standalone converter?

    • admin

      14 February

      hello, AFI1 is not a straight ADAT to AES/EBU standalone converter. But if you use with a DAW software then you can assign the I/O to so such things.

  38. acousticsguru

    25 February

    Dear Kent

    There’s one detail I don’t get:

    “It is very usual that AFI1 becomes the standard for dCS Delius/Elgar user in computer audio playback, because of DualAES and WLK input/output as you explain. When playing HiRes, you will be using AFI1 as master clock instead. AFI1 will not alternate the clock frequency from WLK input.”

    I own a Delius and Purcell. AFAIK, the Delius “expects” a 96 kHz clock frequency playing back 24/192 Dual AES (88.2 kHz respectively for 24/176.4) – does this mean, the AFI1 can be set to output half the sampling frequency as the WLK output so this works?

    Thanks in advance!

    Best regards, David.

  39. admin

    27 February

    Hello David, the AFI1 is not a sampling rate converter, and it does not accept the half rate WLK connection. It becomes a standard for a lot of Delius/Elgar customer because it supports the DualAES connection for HiRes playback.

    In term of clock, if you have a WLK which can provide 96kHz, 192kHz wordclock signal, AFI1 can slave to it. But for dCS master clock (Verona), you cannot provide 48kHz WLK signal to AFI1 while working with 192kHz,96kHz materials. Therefore you will only use AFI1 internal master clock for playback from firewire (computer). But of course this is absolutely no problem with the Weiss quality.

  40. acousticsguru

    27 February

    Dear Kent

    Thanks so much for your reply, much appreciated!

    If I understand correctly, there would be no difference in using the INT202 in the type of setup you’re describing?

    That is, unless one adds a system master clock to slave AFI1, Purcell and Delius (for e.g. a likely application such as redbook playback upsampled to 24/176.4, setting the word clock to 44.1 for the AFI1, 44.1 for the Purcell, and 88.2 for the Delius due to the Dual AES mode) – in other words, a clock such as Antelope Isochrone OSX would fit the bill for AFI1 implementation?

    The latter, a technically neat “studio-like” solution, I guess, easily totals three times the cost of using the INT202. Do you think it would be worth it, or is the trademark dCS jitter rejection and AES clock signal extraction so good it won’t make enough of a difference?

    Best regards, David.


  41. admin

    27 February

    Dear David,

    INT202 is the perfect solution for your describe system. AFI1 is only required for customer who “thinks” external master clock would improve sonic quality. In Weiss and a lot of experts in the field would suggest high quality internal clock would be ideal choice.


  42. acousticsguru

    27 February

    Do both the AFI1 and INT202 add 8 “zero” bits to incoming 16-bit samples, and automatically output 24-bit samples, by the way? If so, does this affect a dCS Upsampler like the Purcell?

    Best regards, David.


  43. admin

    1 March

    Yes, basically this is the case which both AF1 and INT202 when output 16bit. Both units are bit transparent to the source. And this does not affect the Purcell for up-sampling.

  44. acousticsguru

    2 March

    Dear Kent

    Your advice is very helpful, most appreciated! One more question if I may: if used with a master clock, will the AFI1 accept every word clock frequency it is able to convert (that is, it will slave/sync to word clock IN rates up to 192 kHz)? This may seem logical, but I would prefer to be sure (consulted the online manual, couldn’t find the answer there). Thanks again!

    Best regards, David.


    • admin

      2 March

      Hello David,AFI1 supports up to 192kHz wordclock while its internal master clock also output up to 192kHz too.Hope this helps.

  45. acousticsguru

    2 March

    Or, because the mode is Dual AES, does it “expect” a word clock IN of 96 kHz converting 24/192 music samples?

    I am looking for an interface to connect the Mac to the DAC. I own a worldclock grimm CC1 and therefore I am looking for a interface with wclock input. There are not many option at the moment. Somewhere I read that the INT 203 is able the be slaved to a wclock via AES. If its true how might it work?

    Might Weiss bring up an consumer interface like the INT 202/203 just with wclock input?

    What about the Weiss Vesto. I can’t find it anywhere.



    • admin

      7 April

      Hello pedenudo,

      The INT203 can be slaved to external clock with AES connection.
      AFI1 is the Weiss pro interface with WLK I/O.
      The Vesta is an old discontinued model.


  47. pedenudo

    8 April

    Thanks for the response.

    To slave the int 203, I just would take a AES/EBU -cable from the Grimm-clock output to the int 203 AES/EBU-input and chose the frequence needed at the Grimmclock and just take a other AES/EBU-cable from the int 203 to the DAC?
    I use the AES/EBU input output of the Grimm to reclock the digital signal from a CD-Transport. Would it be possible, if there is no signal from the computer, to go with the whole musical data trough the int 203 to the DAC?

    thanks in advance

    • admin

      9 April

      Yes, you slave the INT203 via AES from Grimm CC1. Select the Sync source from AES under Weiss Firewire Panel. The only thing is you will need to match the playback sampling rate manually since it doesn’t run internal anymore. Eg, your Grimm is set at 192kHz and you want to playback CD (44.1kHz) format.

      But this is same case for all kinds of external clocking setup.

      • pedenudo

        9 April

        Thanks for the response,

        yes this is clear, that I have to change the sampling rate manually, and this ok.

        Just the second part of my question. Is it possible to reclock the signal from the CD-Transport via Grimm CC1 and transmit the signal via the INT 203 to the DAC? It sounds a bit weird but my setup is a CD Transport than the CC1 and then the DAC. I would like to connect the Computer to the set up as well but using the CC1 as the reference clock. The problem is there ain’t so much interface that offer the possibility to connect a wclock.

        Maybe a better solution would be to have a cable that has one ending the standard bnc and the other ending the AES to go into the int203. Would it be possible to configure such a cable?

    Hello, i have a DCS P8i mk2 a Grimm CC1 Clock and a Rotel 991 (modded with lcaucio xo2). I usually use the DCS but i still have the rotel 991 to use with HDCD recordings,
    I have conected Spdif out of rotel to Grimm with an aes-ebu adapter (AES in) and AES out fromm Grimm to AES in in DCS acting like a dac, this way Grimm Reclocks the signal and dejitter. In this way i use gRIMM as master. I suppose if does not affect the frequency i set in grimm and only copy the frequency.
    Do i need to connect the Grimm as slave with another cable from DCS p8i word out to Grimm clock in? i suppose this word input would be to connect with the transport, (the rotel does not have wordclock out or in)

      Hello Raul,

      We need to break down your setting in various way since it is very complex.
      The key point is in any digital audio system, there is always ***just ONE MASTER clock***

      1) dCS P8iMK2
      If it works as a standalone CD/SACD player, it is the MASTER sync obviously.

      2) dCS P8iMK2 + Grimm CC1
      Grimm CC1 as the MASTER sync, you need to hook up the Wordclock (WLK) cable from CC1 WLK out to P8iMK2 WLK in.
      dCS P8iMK2 set sync source from WLK IN BNC

      3) Rotel 991 -> SPDIF -> Grimm CC1-> AES -> dCS P8iMK2
      Rotel 991 will be MASTER
      Grimm CC1 in Slave mode locks to the incoming SPDIF, and output thru AES to dCS
      dCS is also in Slave mode locks to the incoming AES signal, or in Slave mode locks to the WLK in BNC since above setup 2) has already connected/set such way.

      In 3) your Grimm CC1 cannot act as MASTER since the source is the MASTER and the source is the Rotel 991, but your chain cleans up the stream before d/a conversion.
      The only way to let Grimm CC1 act as MASTER is your transport/source (e.g. Rotel 991) also has WLK input capabilities.

      Hope this help.

      Your situation is not that difficult since you only use 44.1kHz mainly for CD or SACD(dCS). But if you also playback files from network player/computer with 96kHz, 192kHz then it becomes even more complex.

        obviously i put Grimm as master with DCS reading cd, with Grimm word out to dcs word in.
        in case 3 the rotel does not have word clock input. I have just tried putting the Grimm as slave. My doubt was if i colud put grimm as slave without using the wordclock in it has (GRimm), as i see the Grimm can be used as slave (seems it syncronize with the aes ebu input withou using wordclock input). I remember you the Grimm has 16 output anmd 1 input for wordclock in, seems that is not neccesary.
        The slave begins blonking but it holds, get signal. It gets signal with aes ard word in, the two but not neccesary both

        thanks a lot

    the last question,
    do i need a t and 75 ohm BNC terminator? in which side? both?

      Hi Raul, you do not need a BNC terminator. Just hook up with regular BNC cable to the I/O.

    Hello i would like to send an aes in directly to an aes out within the Weiss. Is that possible and if so how?
    Thanks for your help.

      Hello Marco, AFI1 does not include its own routing software. You will need to software solution to perform this task. Usually we do it in our DAW (digital audio workstation) during recording/mixing/mastering. Do you have such software? Are you using Windows PC or Mac platform? Cheers and stay safe.
