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.
