Customising the Control Unit
29
Use the A and V keys to change the sensitivity.
For example, the display will show:
12dB
Switch between the source you are changing and the
reference source until they sound equally loud.
Repeat the procedure for your other sources.
When you have finished programming levels, switch the
power off and on again to restore the control unit to normal
operation.
If you know the output level of your sources you can probably
set the gains by calculation. The following table shows the
correspondence between the gain and sensitivity on the
standard audio inputs and on the LP inputs:
Gain A2-A6 LP MM LP MC
0dB 150mV 3mV 210µV
3dB 110mV 2.2mV 150µV
6dB 75mV 1.5mV 110µV
9dB 54mV 1.1mV 75µV
12dB 38mV 750µV54µV
