Tubecore 500

Nothing sounds better than the vari-mu hit hard.

Master of the dirty sound.

The TUBECORE 500 is a full symmetric transformer balanced 500-series compressor. The structure is based on the typical vari mu solution. The TUBECORE 500 is a true tube mono compressor where compression is achieved using the remote cut-off of tube biasing. Could be used as a mono tracking compressor or (as a matched pair) as an advanced mastering tool.

"No compromise device - all tubes are powered by 250V DC!"

Every single TUBECORE 500 is hand made with high quality, matched components (1% metal film resistors, Wima caps). It is equipped with JJ tubes and individually calibrated to give you the unique and unspoiled experience of one of the best Vari-mu compressors in the history. We have spent hundreds of hours designing the TUBECORE, to make sure that it is as simple to use as it is versatile. Not only for harmonically rich drums and guitars, but also for huge vocals and bass instruments. Two audio transformers (Sowter and Carnhill) have been used to provide excellent performance.

Using two TC500 as a stereo pair will allow you to use it as an excellent mastering compressor!

Options, options..

TUBECORE 500 has an option of linking two mono modules into the stereo pair. The module with deeper compression set (or slower attack/release settings) will become the master module, that controls the other TC500 unit. You also have an option of choosing input and output levels of your Tubecore 500 unit with extra jumpers on the back of the PCB. Adjusting these levels might be handy if you would like to use extra deep compression.
