• Drastically improves the listener experience in any space — with any sound system
• Accurate subharmonic-synthesis coupled with low frequency enhancement
• High Frequency Expanse uses wave shape manipulation to add clarity, while expanding and solidifying the perception of stereo image from any seat. The effect is especially effective with multi-box systems
• 0dB and +10 level LEDs
• Bypass control you’ll never use
• Separate subwoofer output with level control
• Balanced XLR and 1/4" TRS inputs and outputs
• Great for studio use, too

CPS-1203: The single most significant improvement that you can make to any sound system.
It has been said that, “Nobody ever bought a CPL-1203 by reading about it…but nobody could ever resist buying one after they’d heard it in action.” Honest to gosh, it’s that impressive. So if you don’t like to read, visit a Crest Performance dealer and get a demo. ‘Cuz there isn’t a system on earth that doesn’t sound better with a CPL-1203 in the signal chain. Forget pre-conceptions you may have about “exciters” or subharmonic synthesizers. Yes, the CPS-1203 can add extra fundamental bass to your mix. And it can dramatically increase treble clarity and detail. But it so seamlesly integrates these functions and does so much more that it truly qualifies as a “magic box”…regardless of whether you’re running a modest system or a huge line array.

More bass. Better bass.
The CPS circuitry tracks existing bass information and then generates subharmonics an octave below. This isn’t a new concept but the CPS-1203 does it better without muddying the sound. Suddenly, bass guitar kick drums and floor toms have GUTS. Yet the mix stays clean with room for other instruments in the mid-bass region.
Next to the Subharmonic control is a Low Frequency Enhance control that lets you boost natural bass frequencies to “fill in the gap” above new subharmonics. There’s also a Frequency Shift control that optimizes subharmonic tuning for large or small speaker systems and a separate subwoofer output with level control to truly harnessing CPS-1203’s awesome potential bass output.

The fog is lifted.
Take the CPS-1203 out of a PA system and the program -material immediately sounds like it’s playing through a thick wool blanket. That’s the CPS’s High Frequency Expanse circuitry in action. But it does far more than just synthesize high-frequency harmonics that add detail and sheen to cymbals, acoustic instruments and vocals.

A consistent sound pattern.
With many horn-loaded systems, phase interactions between the output of left and right speakers can cause variations in sound clarity, called lobing. One person sitting fives seats away from another may not get the same sound quality — regardless of whether you’re running a stereo or mono PA.
Proprietary circuitry in the CPS-1203 applies sophisticated phase changes to program material, aurally affecting our perception of lobing, widening the stereo image and solidifying the sound image so it seems to be coming from the stage, not the speakers.

You simply gotta hear it.
No amount of scrolling web copy can equal a quick demo of the CPS-1203. Nothing else on the market can make such a pleasant sound improvement while avoiding an unnatural, synthesized effect.
Added bonus: The CPS-1203 not only makes any installed or mobile sound reinforcement sound audibly better, but it’s also a fantastic studio recording tool for treating individual instruments or your final 2-track mix.
