Features
Your dual-channel (stereo) amplifier can optionally be configured to deliver double the power from a single (mono) channel. It also provides the following features:

•Powerful AB+B class circuitry yields maximum efficiency with minimum crossover “notch” distortion.
•IOC® (Input/Output Comparator) alerts of any distortion that exceeds 0.05% to provide proof of distortion-free performance.
•Signal presence indicators verify the presence of amplifier output.
•Detented level controls for precise repeatability.
•Ultra-low harmonic and intermodulation distortion result in the best dynamic transfer function in the industry.
•Very low noise and wide dynamic range.
•High damping factor provides exceptional loudspeaker motion control.
•Convection cooling system eliminates fan noise and maintenance.
•Mounts in a standard 19-inch (48.3-cm) rack.
•Front-panel headphone jack.
