The Phoenix Mastering Plus
The Thermionic Culture Phoenix Mastering Plus is a stereo compressor, which can be used as a pair of mono compressors. It has a 'soft knee' or 'variable mu' characteristic in that the compression ratio increases with the amount of compression being used. Initial compression is 1.2:1 increasing to 5:1 at 15dB compression. The Phoenix is being updated continually and this unit is the Master version (suffix M) with higher stability and faster release than earlier models. A side chain filter has now been added to provide 75Hz & 150Hz, but more permutations are possible when the MC is used in stereo mode with the link switch engaged.
The Master Phoenix is easier to recall as it has a mixture of indented and switched controls and the screwdriver adjustment on the chassis behind the meters controls the current through the valves on this unit, so this corrects to some extent for valve ageing. A screwdriver is supplied with the Master Phoenix and should be used periodically to adjust the meters to zero Stepped Input & Output controls * 6 position switched attack control * 7 position switched release control * 11 position switched threshold control
