Sony XM-GS4 70 watts RMS x 4 - 4-channel Hi-Resolution Audio Compatible Amplifier

Plays your music loud and clear

This Sony amp uses a heavy-duty transformer and premium capacitors to maximize sonic accuracy.

Sony's XM-GS4 4-channel amplifier will drive your whole system, sending 70 watts RMS to each of your front and rear speakers. Or you can switch the amp into 2-channel mode to power a couple of subs with 160 watts RMS each. This compact amp sports a hefty heatsink that gets rid of the heat that's generated when you're pushing your system hard. The XM-GS4 also uses a cooling fan, which automatically adjusts its speed for the heat it detects, ensuring this small amplifier will always produce the power that's expected.

Ready for high-resolution music

The XM-GS4 can reproduce frequencies as high as 100,000 Hz, so your high-res files and downloads will come to life with pin-point clarity. You don't exactly hear those extreme high tones, but they add ambiance to your music, increasing realism and emotional impact. The XM-GS4 works its magic best when paired with a high-resolution source, like Sony's matching RSX-GS9 digital media receiver, and tweeters capable of reproducing those ultra-high frequencies, like Sony's XS-GS1 supertweeters.

More Features

You'll find all the connections on one side of the amp, which makes wiring simpler and neater. The tuning controls sit protected under a cover so they won't get inadvertently moved. You'll find separate controls for the front and rear channels on this versatile amp. You can run two speakers and a sub, for instance, and use the correct high-pass, low-pass, and subsonic filters to get the tone right. You'll appreciate the bass boost, if you need a little extra punch. Sony protects this amp with a 3-year warranty, and that says a lot.
