TC Electronic C400XL Dual Gate Compressor

The C400XL is a supreme Dual Gate/Compressor specially designed for audio professionals on the road. Combining award-winning multiband compression technology with an extremely fast and intuitive user interface as well as a super silent click free gate, the C400XL is made for the uncompromising live engineer.

Multiband dynamics technology
The C400XL uses advanced TC Electronic multiband dynamics technology to compress any source – from vocals and percussion to guitars and even keyboards. If you want the sound of a full band/one band compressor you can do that too; even de-essing and de-hiss is an option. The inherent transparency of the multiband compressor brings out the qualities of the source material, yet secures a firm and consistent level. The optimized and super-fast gate offers a click free and high precision gating of any source.

Three strikes and you’re in
The C400XL stands out in three distinct areas that make it the ideal unit for the live circuit. First there is the sound quality – this quality is ensured by source-based multiband compression and ultra fast gating. Another great aspect of the C400XL is its versatility – adapt to any source, analog or digital, decide on gate, compression or a combination, and C400XL is up for the task at hand. And finally there is the intuitive, fast use of C400XL – source-based compression, intuitive user interface and a mix knob for parallel compression makes for a fast, professional unit.

Intuitive – yet advanced
Like the C300, C400XL features a TC Electronic exclusive ‘Mix’ knob allowing parallel compression without complicated routing schemes.

To assure smooth operation, C400XL is equipped with high resolution input, gain reduction metering and threshold LED indication. Choose between true dual mono for superior channel separation, stereo or serial operation. C400XL features brickwall limiting for peak stop and hot levels prevention.

Analog and digital connectors
C400XL is the ideal choice for parallel compression, gating and/or compressor applications. A C400XL channel transforms from multiband compressor to ultra fast gate and back at a flick of a switch. Gate and compressor functions can be serial or parallel at the choice of the engineer, thus allowing e.g. awesome combinations of compressor and gate on a snare drum giving that tight and snappy impact sound. Balanced Analog (XLR) and Digital AES/EBU (XLR) connectors make C400XL the perfect solution for any pro sound engineer looking for high-end compression/gates to complement his analog or digital console.
