In order to enable you to adjust the overall volume on the surround decoder, simply
switch off the volume control on the DPA 300.
The Unity Gain function can be activated by holding down the Split button.
The following notification appears in the display:
In order to activate the Unity Gain function, select “YES” by turning the volume
control and hold the volume control down for about 5 seconds.
ATTENTION!
Activation means that the volume control is bypassed. The full volume is set when this
function is switched on while music is playing.
You can damage the loudspeakers this way.
In addition, your hearing may be damaged due to the extreme volume.
If you do not wish to activate the Unity Gain function, use the volume control to select
“NO” and end the function by pressing the volume control.
This adjustment option is only available to you if the Split button has been pressed on
the pre-amplifier. “Split” lights up on the display as soon as Split is pressed.
The amplifier is now set for surround operation.
As soon as you press the “Split” button and cancel the split function again, the volume
module becomes reactivated and you can control the principal loudspeakers’ playback
volume on the DPA 300 again. If you switch the amplifier to Standby, for safety
reasons the Unity Gain function is likewise switched off.
