Product description

CS-5501 is a multi functional channel strip providing all necessary tools to process all kind of audio signals like vocals and instruments.

CS-5501 is the successor of the very popular CS-3301. It keeps the smooth sound of CS-3301 and provides much more flexibility in all tracking and mixing situations.


The double compressors control the dynamics of the signal, either stereo or Mid/Side.


The double (noise) gates suppress noise or any other signal below a certain level. The expanders increase the signal below threshold.


The double Deesers are a kind of dynamic EQ. They compress/expand the signal in a defined frequency range depending on the input/side-chain signal.


Saturation adds odd or even harmonics to the signal.


The two limiters keep the signal below a certain “ceiling” level.


CS-5501 comes with double 7 band filters, shaping the sound accurately and naturally.

Metering & Monitoring

The dual meter monitor level of input/output signal and gain reduction of the compressors, deesser and limiter. It provides VU, RMS, Peak and EBU metering including calibration. On top CS-5501 offers flexible signal monitoring.


The oscilloscope displays the signal amplitude over the time. The buffer of the oscilloscope stores one second maximum.

Spectrum analyzer

The spectrum analyzer displays the frequency spectrum of the audio signals including EQ response curve.

Oversampling & Clip stage

CS-5501 offers top class oversampling, smart bypass function and a clip stage.

Perceptual loudness matching

The perceptual A/B loudness matching function helps you avoid the pitfall of 'louder is better'.


The routing section orders freely the individual effect modules and lets quickly enable or even solo the effect modules.

Side chain support

The side chain section lets you deeply control internal or external side chain signals.

Customer feedback

Guys, IMO this is now the BEST *workhorse* channel strip on the market. It's absolutely phenomenal. I love it. Congrats to the developer for a superb plugin that will hopefully find much love and respect in the market. This developer deserves it.
