AMP CS2's amplification (gain) can be selected by turning the volume knob or by
remote control, not as usual by attenuating the input level, but by setting the gain
lossless according to the actual requirements.
The DIGM setting is always “10" after Power OFF / ON, for having a safe volume
protecting your speakers.
In a consistent B.M.C. chain with an optical DIGM Control connection the gain will be
selected by the B.M.C. DAC volume control.
DIGM = Discrete Intelligent Gain Management
The gain adjustment is done in precise 1 dB increments, which are indicated on the
DIGM LED display: 00 - 66.
At DIGM 39 gain is about 1:1.
At DIGM 55 gain is so high that a full scale signal from a digital device with standard
level output (eg B.M.C. DAC1 or BDCD1) will drive AMP CS2 close to maximum, without
pushing it into clipping.
(For analog devices, there is unfortunately no well-defined limit.)
About DIGM 55 is recommended as a Standard Power Amplifier Gain Setting for high
listening levels. For lower listening levels a lower DIGM setting is recommended for
less noise and a better sound.
DIGM 66 is the highest possible gain setting with about the same amplification as
other power amplifiers. We recommend using DIGM 66 only if required. A lower
DIGM setting compensates by better sound quality.
At DIGM 00 the input is switched off for a complete mute.
