Class-D Subwoofer Amplifier

XM-GS400

The Sony® GS-400 Class-D subwoofer amplifier affords incredible installation flexibility thanks to its compact size and packs quite a punch. GS series amplifiers offer tremendous value including convenience features such as: modern cosmetics, variable cross-overs, multiple channel configurations and singe-side electrical connections to suit almost any application.

Features Specifications

Amp Design

The XM-GS400's 4/3/2 channel configurable output, compact chassis size and single sided connections provide multiple mounting options while maximizing output and control for your audio system.

4 Channel Stereo Output

less than 1% THD+N. At 2 ohms stereo, the XM-GS400 delivers 80 watts RMS per channel at 14.4 volts, from 20 Hz - 20 kHz with less than 1% THD+N.

2 Channel Mono Output

The XM-GS400 delivers 160 watts RMS per channel when front and rear channels are bridged into 4 ohm with 14.4 volts, from 20 Hz - 20 kHz with less than 1% THD+N. This unit has a mximum output power of 350 watts per channel when bridged at 4 ohm.

Built-in Crossovers

The XM-GS400 has a removable top panel that conceals indepentent front and rear 12 dB/ octave variable HPF (High Pass filter) and LPF (Low-Pass filter) crossovers at 50-300Hz. This unit also provides independent front and rear 12 dB/octave sub-sonic HPF (High-Pass filter) crossovers, variable at 6-70Hz to maximize your systems potential. This amplifier also offers independent, variable 0-10 dB 40 Hz bass boost circuit to increase low frequency response.

Input Flexibilty

As well as traditional RCA inputs, the XM-GS100 offers direct connections (High Level Input) to the speaker output of your car audio unit if it is not equipped with RCA line outputs. The auto sensing, high level input feature also allows the amplifier to be powered up without the need for remote power turn on connections.

Warranty

The XM-GS100 includes a 3 year warranty.
