MX422 Field Mixer Meter Repsonse
The meters are set at the factory for a 0 indication of a 0 dbv output level. Non responding meters is caused by only one thing, not enough level from the output amp.

To correct this please verify the following. Start with the channel and master at center positions. Make sure the monitor switch is out.

1. Turn up the trim control to the point where the meters read the level you desire.
2. If this causes too much output from the output jacks, push in the attenuator button near the output jacks.
3. Fine tune the level you want with the channel and aster controls. Finally, if the Pro standard of 0 dB is too hot for you, there are trim pots for each meter inside the unit that can be adjusted down to a 0 indication of about -10dBv.

POWERING
The MX422 features a unique and useful battery scheme. Two separate battery compartments have been provided on each side of the unit. In the event of battery voltage loss during recording, the rear panel BATTERY SELECT switch may be moved to the other position to select the second set of batteries. This is achieved without any signal loss! Rolls recommends using 9V alkaline type batteries, however Lithium or NiMH batteries work as well. To check the status of the selected battery set, press and hold the front panel BATT TEST button. For AC power, Rolls provides the model # PS27s VDC supply to power the MX422.
