Each amplifier is a Class-D design offering high performance in a compact space, with excellent power efficiency. The front panel offers adjustment for each channel plus bass and treble control. Individual protection, clipping and signal presence indicators are provided for each channel. All outputs are via pluggable euroblock connectors with 100V line and 8Ω outputs available. Inputs are via stereo RCA line or balanced euroblock pluggable screw terminals. A high pass filter switch can be activated on each channel. For installations using only one amplifier, a mounting bracket adaptor provides an easy way to bolt into a standard 19” racking system.
