Use: Control, Indicator, and Connector Descriptions

FRONT PANEL

POWER switch- This rocker switch turns the unit on by pressing the top side of the switch. Turn off by pressing the bottom side of the switch.

CHANNELS- These green LED’s illu- minate when the unit detects an input signal on each channel. Each channel’s indicator operates independently. Dual brightness levels indicate signal level. At 40dB below clipping, they will light dimly; at 20dB below clipping, they will light brightly.

POWER indicator- This blue LED illu- minates when the unit has power prop- erly applied and the power switch is in the “On” position.

NUMERIC DISPLAY- This multi-seg- ment numeric display indicates the pre- set selected. The decimal point after the number indicates “lock” mode when illuminated.

A steady display indicates the active preset number. A flashing display indi- cates the pending preset selection.

REAR PANEL

CH 1 INPUT, CH 2 INPUT- These female XLR-combo jacks are the line-level audio inputs to the unit. TRS or XLR connectors may be used.

They are electronically balanced with an input impedance of 8.3k Ohms. If used in an unbalanced configuration, the input impedance is 3.7k Ohms.

Input sensitivity is selectable in software.

CH 1 OUTPUT, CH 2 OUTPUT-- These male XLR outputs provide post-DSP (processed) signal from the unit. Con- nect the outputs to your amplifier’s inputs (or other downstream device).

There is a software-selectable output pad that may be used to attenuate the output level.
