Inputs and Outputs
Analog inputs:
2 bus inputs (bus 1, bus 2); each bus has one stereo pair of unbalanced (RCA) inputs
12 individual channel inputs; each channel has one unbalanced (RCA) input
Input sensitivity (for full output into 8 ohms):
365 mV
Speaker outputs:
12 pairs of 5-way binding posts (standard red and black); one pair per channel
(in bridge mode, speakers are connected to the red binding posts of both channels in the zone)
Minimum recommended load impedance:
Individual channels:
4 ohms (one 4 ohm load or two paralleled 8 ohm loads per channel)
Bridged mode: 8 ohms minimum load per bridged channel
Trigger and control:
Trigger Input (mono 1/8”), Trigger Output (mono 1/8”)
Front panel controls and indicators:
On / Off
(large push button); toggles between Standby mode and On mode
On / Off LED (1); red indicates Standby mode; blue indicates normal operation
Zone Status LEDs (6); blue indicates normal operation; flashing blue indicates a fault
(each LED indicates the status of one zone (channel pair))
(Zone Status LEDs are not lit in Standby mode)
Rear panel controls and indicators:
Power (rocker switch); switches main power
Input Voltage (protected slide switch); selects 115 or 230 VAC line voltage
Power Mode slide switch (Auto / On / Triggered)
Bridge Mode switch (6); labelled BR / ST for Bridge / Stereo (Independent) mode
one per zone / pair of channels; configures each zone / channel pair
as either two separate output channels (Stereo) or one bridged output channel
Line In switch (12); one per channel; selects the input source for the channel
(Bus 1, Bus 2, or individual input).
In bridged mode, only one input is active per bridged pair of channels.
Volume (12); sets input level / gain for each channel
In bridged mode, only one Volume control is active per bridged pair of channels
(the input and controls from the odd numbered channel are active)
AC power input:
IEC C17/C18 (10/15A two wire) type inlet and power cord
AC Power line fuse (rear panel holder)
