Required AC Mains: / Hz (North American units are Hz only); , and - VAC (+/-%) units are available.
AC Line Current,
Volts: . A;
Volts: . A;
- Volts: . A;
At Idle: All amps draw no more than watts.
AC Line Connector: NEMA -P ( A).

Performance
Frequency Response: +/-. dB from Hz to kHz at watt.

Phase Response: +/- degrees from Hz to kHz at watt.

Signal to Noise Ratio, A-Weighted: Better than dB below rated -kHz power; Hz to kHz: Better than dB below rated -kHz power.

Total Harmonic Distortion (THD): -kHz rated power, .% or less true THD from Hz to kHz.

Intermodulation Distortion (IMD): ( Hz and kHz at :) Less than .% at rated power to dB below rated power at ohms.

Damping Factor: Greater than from Hz to Hz.

Crosstalk: Better than dB below rated power, Hz to kHz.

Common Mode Rejection (CMR): Better than dB from Hz to kHz.

DC Output Offset (Shorted Input): +/- mV.

Controls
Level: A detented rotary level control for each channel located on the front panel.

Power: An on/off rocker switch located on the front panel.

Mode: Turn power off before switching. A -position switch located on the back panel below the input connectors which, when turned to stereo, operates the amplifier as independent channels. When "Bridge-Mono" mode is selected, the amplifier bridges the output channels for twice the output voltage.

Sensitivity: A -position switch located on the back panel next to the Mode switch. Switchable between . volts for full output into an -ohm load (default setting), or a fixed voltage gain of dB.

Indicators
Signal: A green LED for each channel which flashes when a very low-level signal (>- dBm) is present at input. May be used for troubleshooting cable runs.

Clip: A red LED for each channel which turns on when distortion becomes audible in the amplifier output.

Fault: Normally off, this red indicator will blink under different conditions:
When the amplifier is first powered up, until the unit is ready for operation. If the heatsinks reach a temperature above normal working limits. If the transformer thermal protection circuit is activated. If amplifier output wires develop a short-circuit. Should the amplifier output stage become non-operational. This circuit may be monitored remotely by plugging a simple switching circuit using an LED or other signaling device into the back-panel RJ- (Fault) jack. Under some conditions, the output of the amplifier will be muted.

Power: A green LED that turns on when the amplifier has been turned on and has power.

Input/Output
Input:
Input Connector (standard module): One Neutrik(TM) Combo connector for each channel which features a balanced
