Reveal the Room-Filling Digital Audio in Your iPod or iPhone

The I-Sonic Digital Audio System features a more powerful on-board amplifier to power it performance-oriented multi-speaker array, and PowerPort® bass venting for truly surprising deep bass response, for real room-filling high performance audio. New Digital Signal Processing delivers more dynamic performance from both standard radio reception and from docking sources. It’s the classic Polk sound -- realistic and enveloping -- from a compact, technologically advanced tabletop audio system.

The I-Sonic DAS Features:

State-of-the-art clear-channel AM/FM reception.

Polk’s I-Sonic 4-speaker array, advanced digital signal processing and patented PowerPort bass all work together to create room filling sound you have to hear to believe.

Exclusive new Digital Signal Processing (DSP) algorithms ensure incredible audio coverage in any sized room, at any volume level. Polk DSP, controling the I-Sonic’s patented four-speaker driver array, delivers big, full-bodied stereo sound.

Powered by a more powerful compact on-board amplifer than any other tabletop radio system.

Docking connections for all iPod & iPhone models, adaptors for iPod Touch and other i-gadgets. Current generation iPods and iPhones with lightening connectors will work with the addition of a lightening to 30-pin adapter.

Dynamic loudness contour technology automatically adjusts bass and treble response to account for your ears’ frequency sensitivity at low volume. You’ll hear rich, well balanced sound even at late-night listening levels.

Dynamic compression technology prevents distortion without changing the character of your audio. Even if you crank it up, the I-Sonic with will always sound crisp, clear and clean.

Easily accessible bass and treble controls.
