AES Input Level Gain Calibration DIP Switch
Input Level Gain Calibration, the analog level which corresponds to a given digital input value, is settable via this DIP
switch. The factory setting is +4 dB (analog) = -20 dBFS (digital). See the silk-screened chart on the rear panel or the
diagram below for Level Gain Calibration settings.

Converted Analog Out Connectors (1-4)
These four Phoenix connectors output analog signals converted from the selected digital inputs (but not the Analog
inputs). These ouputs are not affected by the position of the Analog/Digital Source Select Switch (Item 8, page 8).
These 3-pin male Phoenix connectors are configured for a balanced low impedance connection. Phoenix connector pin-out
information is silk-screened just above these connectors on the rear panel (see Figure-2b).
J
Selected Analog Output Connectors
These two 3-pin male XLR connectors are analog outputs of the selected source(s) as assigned to the left and right
speakers. The left connector outputs the left channel (Channel A) and the right outputs the right channel (Channel B).
Both connectors are configured for low impedance connections and the output signals are not affected by the volume/
balance controls or headphone mute. For XLR pinout information see the diagram below.

Analog Input Connectors (CH. 1 - CH. 4)
These four 3-pin female XLR connectors accept standard analog audio signals and are configured for balanced 70K Ω
connections. For XLR connector pin-out information, see the diagram under Item J. Note that the Analog inputs are
monitored only when the Analog/Digital Source Select Switch (Item 8, page 8) is set to ANALOG.
