Example

851E/W used with an AV receiver 

connected to Input 7 (which is then 

set to fixed gain mode). 
5.1 speaker connections shown.

Volume trim

Note: The Volume Trim menu item is hidden if the Fixed Volume is 

enabled.

The relative levels of the inputs can be adjusted by gain trim. This allows 

each to be adjusted so that each sounds the same in terms of average 

loudness when you switch between them. Pick the loudest sounding 

source and trim its level until it matches the average perceived level of 

the others. Repeat this process if other sources also stand out as louder 

than the average. 
To set the input gain trim for each source, press and hold the required 

input source button then select Vol Trim in the submenu:

Press the Enable button and use the volume control to set the gain 

between 0 and -12 dB (the available range is restricted if the volume 

is set very low). Press the Apply button to temporarily hear the new gain 

settings, re-adjust the gain if necessary and press the Apply button 

again. Press the Save button to save and exit the submenu.
Pressing the Current button will display the current volume value. This 

is a useful function when setting new gain value and comparing it to the 

current volume.
The other two settings sets the gain as following:

Minimum

 – Sets the minimum gain value to -1dB.

Maximum

 – Sets the maximum gain value to -12dB.
