Gain/Balance and Maximise
This menu allows gain (output level) and balance to be set, or an automatic gain
setting to get the highest possible level without overload – for CD preparation,
for example. The balance control works in a different way to conventional
(analogue) balance controls, and although is easy to operate, you should be
aware of what it does.

The
dCS 974 has a global gain of -0.01 dB absolute, so when the unit says “0 dB” the overall gain will be
-0.01 dB. This is because noise shaping, dither, and a few other mechanisms can add (small) amounts to an
input signal, but enough to cause digital clipping. The -0.01 dB global gain shift avoids the problem.
