The Thermionic Culture Phoenix Compressor SB is the famous Thermionic valve compressor sound. With side chain capabilities, it is a great choice for bus compression.

The 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 on, or if the unit's not in use for a while, have the Standby on. Switch off Standby and it will instantly come back to full life.

We have also placed the meter zero controls on the front panel for much easier access. Both meters should read "0" when the Phoenix is off standby and not compressing. They can be adjusted easily by any user without harm to the unit.

The side chain filters can be used to cut the Phoenix's compression response to bass frequencies. The filter operates below either 150Hz or 300Hz on each channel and when stereo link is engaged the filters operate at the average of the two sides. This enables the user to choose from 5 filter frequencies when in stereo operation.

The Phoenix is well known for its smooth "soft knee" compression characteristic and excellent specifications. This means that it can be used as a compressor that will not harm your signal quality, whilst subtly controlling dynamic range. It is also possible to drive the unit harder to produce harmonic distortion and higher ratio compression if desired. Many users have found these features bring life to mixes or individual instruments, and control vocals, with a natural "warm" quality.

Contrary to the above, users have found that if the unit is operated in standby mode (it still passes audio) a "symmetrical" distortion occurs, not unlike that produced by overloading analogue tape. Perhaps this fact alongside an exaggerated compression curve lends to the Phoenix in standby mode another dimension.

    Thermionic Culture The Phoenix
    I was looking for a Vari-Mu for mixing but mostly for mastering. I knew that the full tubes point to point type of products made by Thermionic Culture were awesome. Well I have nothing else to say that this piece of gear will stay in my arsenal. Smooth, warm, not that colored with a beautiful something in the low end. Read more
