The Thermionic Culture Phoenix SB is now the standard production version of the Phoenix compressor. Alongside the now classic circuit design of the original Phoenix, it incorporates the side chain filter controls from the previous standard Phoenix SC model with the new addition of an HT standby switch. The additional HT Standby switch allows the user to put the Phoenix into a low power standby mode that is designed to increase the life of the unit's valves and capacitors. When first switching...

This is the latest development in the evolution of the classic Phoenix compressor, first introduced in 1998. After requests from mastering engineers the Thermionic Culture Master Phoenix was introduced in October 2006. This was more recall-able with indented pots and slightly different power supply and metering circuit, in which trimming the meter alters the current through the compression valve so compensating for valve aging. The compression curve of the mastering Phoenix is slightly...

The Thermionic Culture Pullet is a passive EQ which has a sharp focus on mid range frequencies. The Pullet will provide the EQ network to a signal but will reduce the signal level so that a preamplifier with a gain of up to 40dB is needed in order to lift the signal back up to unity gain when the Pullet EQ is set to 'flat' or bypass. The preamplifier is used at the output of the Pullet. The fact is that most people will already have a preamplifier that can be used, either a standalone...

The Thermionic Culture SWIFT EQ equalizer has been designed to be as much at home in tracking individual instruments or sitting across a stereo mix buss to equalise the final mix. . As with other units of theirs, such as The Phoenix, all controls are clearly labeled and setting up the eq is quick and easy, so Thermionic Culture named it after Britain's fastest bird in level flight. THE SWIFT utilizes influences of 2 classic designs of the "golden days" of all valve recording with improvements...
