Key Facts & Specs

 Design: It is a true dual-mono amplifier. This means it has two independent amplifiers inside the chassis, each with its own high-speed switch-mode power supply, sharing only the power cord and the internal cooling fan.

 Power Output (per channel): 350 watts into 8 ohms; 650 watts into 4 ohms.

 Bridged Mono: Capable of pushing an impressive 2,100 watts into 4 ohms.

 Weight & Size: 17 lbs (7.7 kg) in a standard 2-rack-space (2U) chassis, 15 inches deep. This power-to-weight ratio was revolutionary at the time, as comparable conventional amps weighed around 50 lbs.

 Performance: Signal-to-noise ratio of >100 dB, a damping factor of >500, and an operating bandwidth of 15 Hz to 45 kHz.

 Inputs: XLR, 1/4" TRS, and barrier strips for each channel. All inputs can be balanced or unbalanced and are wired in parallel.
