120 Volts: 9.5 A;
230-240 Volts: 5.0 A;
At Idle: All amps draw no more than 90 watts.
AC Line Connector: NEMA 5-15P (15 A).

Performance
Frequency Response: +/-0.2 dB from 20 Hz to 25 kHz at 1 watt.

Phase Response: +/-15 degrees from 20 Hz to 20 kHz at 1 watt.

Signal to Noise Ratio, A-Weighted: Better than 105 dB below rated 1-kHz power; 20 Hz to 20 kHz: Better than 100 dB below rated 1-kHz power.

Total Harmonic Distortion (THD): 1-kHz rated power, 0.5% or less true THD from 20 Hz to 20 kHz.

Intermodulation Distortion (IMD): (60 Hz and 7 kHz at 4:1) Less than 0.1% at rated power to 35 dB below rated power at 8 ohms.

Damping Factor: Greater than 400 from 10 Hz to 400 Hz.

Crosstalk: Better than 55 dB below rated power, 20 Hz to 20 kHz.

Common Mode Rejection (CMR): Better than 70 dB from 20 Hz to 1 kHz.

DC Output Offset (Shorted Input): +/-10 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 2-position switch located on the back panel below the input connectors which, when turned to stereo, operates the amplifier as 2 independent channels. When "Bridge-Mono" mode is selected, the amplifier bridges the 2 output channels for twice the output voltage.

Sensitivity: A 2-position switch located on the back panel next to the Mode switch. Switchable between 1.4 volts for full output into an 8-ohm load (default setting), or a fixed voltage gain of 26 dB.

Indicators
Signal: A green LED for each channel which flashes when a very low-level signal (>-40 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 5 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-11 (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
