Sony's Elevated Standard hi-res amp

Sony's Mobile ES Series XM-4ES Elevated Standard 4-channel amplifier will boost the level of your music while retaining its pristine, crisp, and full-range sound and impact. Capable of handling high-resolution sources and programs, this amp will help make it sound like you're right there with the musicians in the studio or on stage. With 100 watts RMS output per channel, there'll be plenty of volume available for playing your music the way you want.

Signal handling

You can bridge a couple of the amp's channels together to power a subwoofer with up to 330 watts RMS — so you could use the amp to power two subwoofers, or a couple of speakers plus a sub. The front and rear channels both feature wide-range adjustable high-, low-, and band-pass filters, so you can fine-tune the sound to fit almost any combination of high-frequency tweeters, mid- and full-range speakers, and subs. The inputs can be summed and assigned, so factory pre-processed channels can be mixed together to produce full-range signals for the amp to boost. Preamp outputs let you easily add another stereo or mono amp to your system.
