Section 2: Operation

Selected Analog Output Connectors (Left and Right)

These two 3-pin male XLR connectors (CH.A(L) and CH.B(R)) are analog outputs of the selected digital source as

selected for the left and right speakers and level meters. Both connectors are low impedance. The output is not affected by

the volume/balance controls or headphone mute. For XLR pinout information see the diagram under Item G.

Level Meter Calibration, Display Mode, and Reference Level DIP Module

This DIP switch module sets the Line Level (Auto) Calibration feature, the Display Mode, and the Reference Level for

the Audio Level Meters (Item 6, page 8). See page 18 for information on setting these parameters.

Note: An internal DIP switch module sets the Peak Hold, PPM Ballistics, and Alternative Scales. See page 19 for

information on setting these parameters.

Analog Input Connectors (Right and Left)

These two 3-pin female XLR connectors (CH.A(L) and CH.B(R)) accept standard analog audio signals and are configured

for balanced, 40k Ω connections. The unit will monitor signals input on these two connectors when the Analog/Digital

Source Select switch on the front panel (Item 9, page 8) is set to ANALOG. For XLR pinout information see diagram
