Subwoofer Amplifier


 DESCRIPTION

The MODEL 500 subwoofer amplifier was designed to offer performance, value, and flexibility. It incorporates a 500W class A/B amplifier utilizing the patented BASH® technology for high electrical efficiency.

Four independent controls offer flexibility to integrate nearly all subwoofers with the main speakers and the listening environment. The continuously-variable low pass filter network is adjustable from 40 to 120Hz and can be bypassed if it is preferable to use an external filter or one located in an outboard receiver or processor. The continuously-variable phase circuit is adjustable from 0 to 180 degrees to finely integrate the subwoofer with the main listening speakers.

The MODEL 500 incorporates a unique subsonic filter adjustable from 20 – 35Hz that limits/extends power output to the lowest frequency the subwoofer driver is capable of reproducing. This maximizes performance, helps to protect the subwoofer driver from being overdriven and will reduce distortion by limiting extreme subwoofer driver excursions.

A defeatable Auto-power mode turns the amplifier on automatically when a signal is detected. The Auto-power mode can be defeated if it is desirable to use a remote AC circuit to control the amplifier (on/off) power. Dual subwoofer outputs allow multiple woofers to be connected to the same amplifier without having to resort to pigtails, wire nuts, or specialized connectors.
