OUTPUT POWER (per channel) 
Continuous Average Output Power both channels 
driven: 
8 ohms,   20 Hz-20 kHz  0.1% THD  110 W 
  1 kHz  1% THD  135 W  
4 ohms,   20 Hz-20 kHz  0.1% THD  140 W 
  1 kHz  1% THD  200 W 
2 ohms,   1 kHz  1% THD  NR 
Bridged Mono operation:

  1 kHz  1% THD  270 W  
8 ohms,   20 Hz-20 kHz  0.1% THD  280 W 
  1 kHz  1% THD  400 W 
4 ohms,   1 kHz  1% THD  NR 
 
Distortion: THD – 20 Hz-20 kHz from 250 milliwatts to rated 
power shall be less than 0.1%, 0.015% typical. SMPTE-IMD less 
than 0.020% 250 milliwatts to rated power. 
 
Frequency Response:   20 Hz-10 kHz ± 0.1 dB  
      8 Hz-300 kHz +0/-3 dB 
 
Damping Factor:    Greater than 200 
 
Dynamic Headroom:   3.0 dB at 8 Ω 
 
Noise:       -100 dB 20 Hz-20 kHz 
 
Sensitivity:     1V RMS for rated power (8 Ω) 
 
Input Impedance:   20 kΩ  
 
Controls: 
Front – Flush detented gain control, recessed 
AC switch and AC circuit breaker for each 
channel. 
Rear – Mono-bridging and accessory module 
switches. 
 
Indicators:   Bi-color LED indicating DC power – 
OK/Protect mode, LED clip indicator, -30 dB 
and -6 dB signal level indicators, flashing over-
temp indicators. 
 
Connectors:   XLR, ¼” (ring, tip, sleeve) and 3 terminal 
barrier strip inputs wired in parallel, 2-terminal 
barrier strip and 5-way binding post outputs 
wired in parallel, octal input sockets provided 
for input transformers or active accessories, 
ground lift terminal block. 
 
Cooling:   Passive cooling combined with high efficiency 
output stage for reduced operating 
temperatures. Unique circuit configuration 
allows direct metal mounting of output devices 
for reduced thermal stress from short-term 
peaks. 
 
Amplifier Protection:   Indefinite short circuit*, open circuit, 
over-temp, ultrasonic and RF protection. 
Stable into reactive and mismatched loads. 
Inputs protected from overload. All protection 
completely independent on each channel. 
 *Output Averaging short circuit protection 
(U.S. Pat. 4,321.554) 
 
Load Protection:    Individual channel Load Grounding 
output relays provide DC Fault, 3 second 
delayed turn on (transient protection), and 
excessive low frequency protection, Instant 
turn-off, pop suppression and power interrupt 
protection is also provided.  
 
Output Circuit Type:   Full complementary two-level high 
efficiency. 
 
Output Devices (total):   8  
 
Power Supply:   Two completely separate power supplies 
including AC switches and AC circuit breakers; 
only AC cord is common.
