DO Adjust the Settings

Refer to the following illustration, and adjust the controls to achieve the desired results.

Set Phantom Power

Each input has switchable phantom power (+48V) for use with condenser microphones. The

MMX-6-USB ships with the phantom power switches (located on the rear panel) in the OFF position.

When setting up the system, rst determine if the microphones to be connected require phantom

power. If phantom power is required, ensure that the microphone input's individual gain control

remains closed (turned fully counterclockwise), and slide the input's phantom power switch to the ON

position. The corresponding LED illuminates.

Set the Microphone Input Levels

Each microphone input features an adjustable input channel level control on the front panel. The

MMX-6-USB ships with the level controls at the lowest setting (fully counterclockwise, closed

position). Use a at-head screwdriver to adjust each input channel's level.

NOTE: When adjusting the input channel level controls, use slow and easy pressure. Do not force

the control or rotate past the indicated stop.

Each input has an LED to monitor the signal level. When adjusting the level, monitor the input

channel's LED.

•When a signal is present, the LED illuminates green.

•When the LED changes to red during the course of normal speech, it indicates that some

clipping is occurring.

•A steady red LED indicates that the input is steadily clipping. When constant clipping occurs,

reduce the microphone level. Brief amounts of signal clipping may be acceptable while steady

clipping is not.
