Rear Panel Connectors

• AES/EBU In (In 1 and In 2): These two female BNC input connectors

(In 1 and In 2) accept standard AES/EBU signals. These connectors are

configured for unbalanced, 75 connections. Only one of the two AES/

EBU inputs may be monitored at a time. Use the Digital Source

Select Switch

on the front panel to select between AES/EBU inputs In

and In 2. Note that the unit will monitor the selected AES/EBU channel

only when the

Analog/Digital Source Select switch on the front

panel is set to Digital.

• AES/EBU Input Level Gain Calibration DIP Switch: Set the

Input Level Gain Calibration, the analog level that corresponds to a

given digital input value with this DIP switch. The factory setting is +4

dB (analog) = -20 dBFS (digital). See the silk-screened chart on the

rear panel or Figure 1–6 on page 13 for settings.

• Selected Analog Out (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. See

Figure 1–7 below for pin-out information.
