TRIM LEVEL
Source Components can have slightly different volume 
levels resulting in the need to readjust the MXA80 
Volume Control when switching between different 
Inputs. The MXA80 allows the adjustment of levels 
for each of the Inputs for the desired same relative 
volume. The UNBAL and OPTICAL Inputs are used 
in the following example.

Note: The TRIM Level Adjustments made are retained in 

permanent memory.

1. Rotate the INPUT Control to select the UNBAL 

Input and adjust the VOLUME Control for the 
desired listening level.

2. Momentarily press the Front Panel INPUT 

Control to enter the TRIM Mode. Then rotate the 
INPUT Control until “TRIM LEVEL,  

 dB” 

appears on the Front Panel Display. Rotate the 
OUTPUT Control until the Front Panel Display 
indicates “TRIM LEVEL,  0.0dB”. Refer to 
figure 58.

The range of TRIM Adjustment is ± 6dB. Refer to 
figures 59 and 60.

Note: The 

UNBAL 

Input is serving as a refer

ence level or choose another Input frequently 
listened to.

After approximately 5 seconds the Display returns to 
indicate the Input Selection and Volume Level.

BALANCE
The Channel Balance while listening can vary with 
different program sources. When using Loudspeak-
ers, the room acoustics and listening positions also 
can effect the Channel Balance. Use the Balance Trim 
Function as needed to achieve approximately equal 
listening volume levels in each channel. To adjust the 
Balance perform the following:

1. Momentarily press the Front Panel INPUT Control 

to enter the TRIM Mode. Then rotate the INPUT 
Control until “L  BALANCE  R” appears on the 
Front Panel Display. Refer to figure 55.

2. Rotate the OUTPUT Control to change the Chan-

nel Balance, the range of adjustment is 50dB (to 
# –   [    @ %   ‡
steps. Refer to figures 56 and 57.

After approximately 5 seconds the Display returns to 
indicate the Input Selection and Volume Level.

3. Note the current listening level. Then rotate 

INPUT Control to select the OPTICAL Input and 
note if the relative volume is louder or quieter 
than the volume level of the UNBAL.

4. Momentarily press the Front Panel INPUT 

Control to enter the TRIM Mode. Then rotate 
the INPUT Control until “TRIM LEVEL,   .   
dB” appears on the Front Panel Display. Using 
the OUTPUT Control adjust the TRIM Level to 
match the same relative volume level heard when 
listening to the UNBAL Input.

5. In our example, the relative volume level of the 

OPTICAL Input is louder than the UNBAL 
Input, so the trim level for the OPTICAL Input is 
reduced to -2.5 dB. Refer to figure 61. 

6. Repeat steps 1 thru 4 until the relative volume 

is the same between the UNBAL and OPTICAL 
Inputs.

7. Repeat the above steps for the remaining inputs 

with component sources connected until they all 
have the same relative volume levels. Record any 
changes made to the various inputs from the de-
fault settings in the “Input Trim Settings” Chart 
on the next page.

After approximately 5 seconds the Display returns to 
indicate the Input Selection and Volume Level.

MONO/STEREO MODE
By default the Stereo Mode is active for all Input 
Sources however, any Input Source may be assigned 
to Mono Mode. To change Stereo Mode to Mono for a 
given Input Source, perform the following steps:
