To exit the setup menu at any time, press and hold the encoder knob for 3 seconds. The 7-segment display will switch back to the
current output level once the setup menu has been exited.
Note: When the setup menu is exited, the last mode you were in will be the
first mode activated the next time you enter the setup menu. This allows quick access to the parameter you are currently adjusting.
The setup menu is also accessible by the optional m903 infrared remote control. Please refer to the ‘Remote Control Operation’
chapter for a detailed description of how this works.
Following is each available setup menu option, in the sequence they appear.
balanCe MoDe
This provides individual left / right balance control of 6dB in 0.5dB increments for each available output (headphone, Line 1 and
Line 2). To program balance settings:
1
Push and hold the rotary encoder to enter the setup menu, then rotate the encoder until you reach the balance settings,
which are indicated as: bH for headphones, b1 for line output 1 and b2 for line output 2.
2
When you have reached the output you wish to adjust, push the encoder again to enter the balance setting.
3
When no balance offset has been made, both the left and right speaker symbols are shown in the 7-segment display.
4
Turning the rotary encoder clockwise results in a balance adjust to the right. This will be indicated by the right facing speaker
symbol changing to the corresponding balance offset value.
5
Turning the rotary encoder counter-clockwise results in a balance adjust to the left. This will be indicated by the left facing
speaker symbol changing to the corresponding balance offset value.
6
With each detent of the volume control the m903 alternates between adding .5dB to one channel and then subtracting
0.5dB from the other. This continues until one channel is 3dB louder and the other is 3dB quieter.
7
To store your balance setting for the selected output, push and hold the encoder. This will then send you out of the setup
menu and back to the main level control screen.
The m903 stores all three balance level settings in non-volatile memory and recalls these upon each power up.
PoWer UP leVel
This feature allows the user to save specific level settings for each output as the default power up level. While default levels are set
to 0 at the factory, you may want to have the unit always power up at a specified level other than the default. To program power
up level settings:
1
Push and hold the rotary encoder to enter the setup menu. Now rotate the encoder until you reach the power up level set-
tings, which are indicated as: PH for headphones, P1 for line output 1 and P2 for line output 2.
2
When you have reached the output that for which you’d like to enter the power up level, push the encoder again to display
the current power up level.
3
From here you can rotate the encoder to adjust the power up level.
4
From here, you can either push and hold to immediately store the level, which will then send you back to the main level
control screen. Or, push the encoder once (without holding) to exit back to the first level of the setup menu, from where you
can select and adjust another power up level. Note: This option does not store the power up level until you push / hold and
exit back to the main level control screen.
oUtPUt toGGle loCk oUt MoDe
Situations may exist when you need to lock the output level select toggle function of the encoder to prevent inadvertent switch-
ing.
Example: A musician is using the m903 in a live application and the amplifier is on stage for adjustment during the performance.
The m903 may down be out of sight, but within reach. If they accidentally hit the encoder button, the output would toggle and
they would be left adjusting the wrong output.
1
Once this mode is enabled, pressing and releasing the encoder button no longer toggles the m903 through the 3 available
outputs. Pressing and holding the encoder button will still allow the user to enter the setup menu. This mode is reset to OFF
whenever the m903 is power cycled. To activate this feature:
2
Push and hold the encoder to enter the setup menu. Now rotate the encoder until you reach the output toggle lock mode,
indicated by the OL symbol in the 7-segment display.
3
Pushing the encoder once turns the this mode ON, which is indicated by the decimal points illuminating in the O.L. symbol.
