Performance Specifications
Analog inputs:
Twho 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
Analog outputs:
2 bus outputs (Bus 1, Bus 2); each bus has one stereo pair of unbalanced (RCA) outputs which
provide a buffered copy of the input signal
Input sensitivity (for full output):
365 mV (8 ohm load)
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 (which equals one 4 ohm load or two paralleled 8 ohm loads)
Bridged channels; 8 ohms
Power output:
65 watts RMS per channel (x12); into 4 ohms; two channels driven
40 watts RMS per channel (x12); into 4 ohms;
all
channels driven
120 watts RMS per channel (x6); into 8 ohms (bridged); two channels driven
80 watts RMS per channel (x6); into 8 ohms (bridged);
all
channels driven
32
watts RMS per channel (x12); into 8 ohms
S/N ratio:
> 95 dB (A-weighted)
Frequency response:
20 Hz to 20 kHz + / - 0.2 dB at 1 watt (- 2.0 dB at 80 kHz)
Trigger and control:
Trigger Input: 3 - 20 V AC or DC
Trigger Output: 12 V DC 100 mA max
Protection:
The PA 12-45 is protected against excessive operating temperature, shorted
speaker connections, ground faults, and other common fault conditions. If a fault occurs,
the PA 12-45 will automatically power down and the front panel status LEDs will indicate the
faulty channel(s). Each channel status indicator shows the status of one
zone
(a zone is a pair of
channels). If a channel experiences a short or other fault, both channels in that zone (but not the
other zones) will go into protect mode and shut down; the channel status LED for the zone in protect
mode will turn FLASHING blue. To reset the protection, turn the PA 12-45 Off and then On again
using the REAR PANEL POWER SWITCH after the fault has been removed.
