Proposition 65 Notice WARNING: Cancer and Reproductive Harm -
Low Noise Preamplifier Circuit

Maximum low voltage signal from the source unit comes into the amplifier through a low voltage circuit which delivers minimal distortion through the amplification process.

RCA Inputs

Highest sound quality connection with quality RCA materials helps prevent interference and minimize distortion in the signal path.

Operation Mode

Four Channel Stereo, Dual Stereo Bridged, Stereo + Bridged Mono, Dual Bridged Mono

Crossover Type

Fully Adjustable 12dB Crossovers

Electronic Equalizer

Control of amplifier output with on board electronic crossover to tailor specific frequencies to speakers and subwoofers.

Class / Topology
