過去兩個月，Weiss 升級了 40 多部 Golden DAC module (DAC-B)，得到的反應都非常正面，聲音獲得進一步提升，很大部分要感謝 OP1-BP 離散輸出級。最下方附上 DAC-B 的數據表。













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.
