Specifi cations
The following applies to units in Stereo mode with 8-ohm loads
and rated input sensitivity unless otherwise specifi ed.
Performance
Sensitivity
(volts RMS) for full rated power at
4 ohms: 1.025.
Frequency Response
(at 1 watt) 20 Hz to 20
kHz: ±0.75 dB.
Phase Response
(degrees at 1 watt)
at 10 Hz:
–10.
at 20 kHz:
+19.
Signal-to-Noise Ratio
(20 Hz to 20 kHz)
A-weighted, below rated power:
> 100 dB.
No weighting, below rated power:
> 97 dB.
Total Harmonic Distortion (THD)
at full band-
width power, from 20 Hz to 1 kHz: < 0.15%.
Intermodulation Distortion (IMD):
(60 Hz and
7 kHz at 4:1) from full rated output to –40 dB:
< 0.3%.
Controls
Level:
Two front-panel rotary level controls,
one for each channel. Blanking plugs cover
the level controls to prevent tampering.
Power:
Front-panel switch; on when in the UP
position.
Filter Switches:
One per channel; three-posi-
tion back-panel switches set the internal high-
pass fi lter frequency. Frequency setting is 30
Hz when switch is in left position; 15 Hz when
switch is centered; and bypassed when switch is
in right position.
Limiter Switch:
Back-panel switch offers loud-
speaker protection against moderate amplifi er
clip when set to the “IN” position.
Fuse:
Provides overload protection.
Indicators
Clip:
Two front-panel red LEDs, one for each
channel, illuminate when the channel’s output
signal is being overdriven.
Power:
Green front-panel LED indicates
amplifi er has been turned on and AC power
is available.
Fault:
Yellow front-panel LED illuminates when
amplifi er is in protect mode. Also illuminates
briefl y during normal power-up when amplifi er
is fi rst switched on.

• THX-approved.
• Simple, reliable design incorporates many
popular features.
• Selectable high-pass fi lter on each channel
enables amplifi er to work more effi ciently
when full band-width is not required.
• Pair of linear optocoupler clip limiters pro-
tects loudspeakers from being overdriven.
• Housed in a rugged, all-steel 3U chassis.
• Effi cient forced-air fan prevents excessive
thermal buildup.
• Electronically balanced XLR inputs and
binding post outputs (export models feature
touch-proof binding post outputs).
• Features precision detented level controls,
power switch, and four LEDs, which indi-
cate clip for each channel, power and fault
conditions.
• Three-Year, No-Fault, Fully-Transferable
Warranty completely protects your invest-
ment and guarantees its specifi cations.
