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.

High Level Inputs

Easily tie into OEM audio systems that do not offer RCA output to maximize after market amplifier power.

Operation Mode

Mono only

Crossover Type

Variable Electronic 12dB Per Octave

Electronic Equalizer

Fully Adjustable 12dB Crossovers
