Specifications

The following applies to units in Stereo mode with 8-ohm loads and rated input sensitivity unless otherwise specified.

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.

Damping Factor (8 ohm) 10 Hz to 400 Hz: >200. Crosstalk (below rated power)

at 1 kHz: –82 dB.

at 20 kHz: –58 dB.

Voltage Gain (at maximum output): 31 dB.

Power

Output Power:

TX

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 filter 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 amplifier clip when set to the “IN” position.

Fuse: Provides overload protection.

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%.

Load Impedance: Safe with all types of loads. Rated for 2 to 8 ohms.

AC Line Voltage and Frequency Configura- tions Available (±10%): 120 VAC/60Hz and 230 VAC/50 Hz.

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 amplifier has been turned on and AC power is available.

Fault: Yellow front-panel LED illuminates when amplifier is in protect mode. Also illuminates briefly during normal power-up when amplifier is first switched on.
