The m904 provides the user with a stored Main Output Level Preset. Under normal operation, this is accessed by
“double clicking” the Main Level encoder switch. This feature allows the user to quickly set the output to a prede-
termined level. To change the Main Output Preset Level, do the following:
Enter CAL mode by pressing the CAL switch. The switch LED will begin to flash, indicating that you’re now in cali-

bration mode.
Press the MAIN encoder switch.

The LCD display will read “SPEAKER OUTPUT LEVEL PRESET”.

“CAL” will be displayed in the headphone level LED display, while the current preset level will be shown in the MAIN

LEVEL 7-segment display. The main output will be updated to the preset level.
Rotate the ‘main level/edit’ rotary encoder in a clockwise direction to increase the level preset value (0.0 to 100.).
5.
Rotate the encoder in a counter-clockwise motion to decrease the value. When adjusting, the output level will
change in real-time allowing you to accurately set the appropriate listening volume.
Once you’re satisfied with the new level, you can select a new function to edit or exit. Exit CAL mode and return

to the normal operating state by pressing the flashing CAL switch.
Whether you exit CAL mode here or not, the
Main Output will now be set at the preset level until further changes are made.
