Thank you for all supports. In less than 2 months (60days) we have installed more than 40 Golden DAC module (DAC-B) sets. All feedbacks are extremely positive and have reported the Golden DAC Module (DAC-B) is upgraded the sound quality significantly. Thanks to the flagship OP1-BP discrete output stage.
Here is the data sheet of DAC-B:
The measurements below have been taken at the following conditions (unless noted otherwise):
- 1 kHz measurement frequency
- maximum selectable output level
- 176.4kHz sampling frequency (Fs)
- 22kHz measurement bandwidth, unweighted
- 0 dBr equals the output level at 0 dBFS input (dBFS = deciBel Full Scale)
XLR Connector Output:
Output is DC coupled, short circuit proof
Output Impedance: 94Ω.
Output level selectable from:
7.5 Vrms, +19.7 dBu, with a 0 dBFS sinewave input
2.3 Vrms, +9.7 dBu, with a 0 dBFS sinewave input
0.75 Vrms, −0.3 dBu, with a 0 dBFS sinewave input
0.23 Vrms, −10.3 dBu, with a 0 dBFS sinewave input
These levels are achieved with all faders / gain trims set to maximum level.
RCA Connector Output:
Output is DC coupled, short circuit proof
Output Impedance: 47Ω.
Output level selectable from:
3.75 Vrms, +13.7dBu, with a 0 dBFS sinewave input
1.15 Vrms, +3.7dBu, with a 0 dBFS sinewave input
0.375 Vrms, −6.3dBu, with a 0 dBFS sinewave input
0.115 Vrms, −16.3dBu, with a 0 dBFS sinewave input
These levels are achieved with all faders / gain trims set to maximum level.
