input gain control
CPM 3300, CPA 3200E, CPA 4000E
You can adjust the input gain on your input devices so that you can align the volume
levels of your different inputs There are four settings which are x1, x1.5, x1.75 and x2.
This feature is not available on the CPA 2200 and the CPM 2600.
Most modern input devices such as CD players have an unbalanced output voltage of
2V and a balanced output of 4V which does not require any amplification. In fact, to
increase the gain on such an output level can lead to a distortion of the signal.
However, older audio equipment may have an output voltage of less than 2V, in
which case you may like to adjust the input gain.
increasing the input gain
1. Using your remote control press PRE and then the input device of your choice
(eg Disc 1). The display will show
.
2. Press BUS-A (or BUS-B if you are going to record from the Tape 1 output).
The display will show
.
3. Press the volume button marked
to increase the gain to x1.5.
The display will show
.
4. Repeat steps 2 and 3 to increase the gain to x1.75, and repeat these steps once
again to increase the gain to x2.
reducing the input gain
1. Using your remote control press PRE and then the input device of your choice
(eg Disc 1). The display will show
.
2. Press BUS-A (or BUS-B is you are going to record from the Tape 1 output).
3. Press the volume button marked
to decrease the gain.
4. Repeat steps 2 and 3 to reduce the gain again.
Once you have adjusted the gain setting on an input device your amplifier will
remember the setting, even if it is switched off for many months.
to reset all gain levels to x1 on Bus A and Bus B
1. On the front of your amplifier press and hold the A button for three seconds. The
display will show a gain setting, for example
.
2. Press and hold the Set(S) button until you see
then release the button
and the display will show five dashes
.
3. Select a source on either bus system.
