Schematics volume/gain settings

The volume controls, which can be set on the CU 6010 user interface as described in the previous section are shown in the following schematic.

￿Setting of Loudspeaker volume

1.Set the Mic>Loudspk to 0dB

2.Turn up the Loudspk Volume to the level needed in the loudspeakers.

￿Setting Line input level

1.Apply the signal to the Input connector

2.Turn up the input level on “LineInlevel Adj” until you can see the overflow indicator.

-LineIn->Loudspk: -17dB ▲

-LineIn->LineOut: 10dB >LineInLevel Adj:* -6dB

-Loudspk volume: 3dB ▼

”*” Overflow indicator on line input

3.Turn then the InputIn level down –8 dB to –12dB from the clipping level. Depending of the source connected, there might be different “overhead” needed. But normally 8-12 db is enough.

4.Turn up the Linein >Loudspk Volume to the level needed in the loudspeakers

The principle is that the level of signal from the Line Input is combined of two settings:

“LinelnLevel Adj” and “ LineIn->Loudspk” .
