Kontaktiere unsManley Stereo Variable Mu Limiter Compressor "The Works" is the standard version of the compressor carrying both factory modifications at once: T-Bar in the gain control stage and MS in the signal path.
Deeper reduction and separate work on the centre
The two modifications answer different limitations, but together they open a working range the base version never reaches. T-Bar swaps two 5670 triodes for four 6BA6 pentodes, which keeps the limiting curve smooth even when you go past six decibels of reduction. MS splits the signal into sum and difference before the gain stage, so you can press on the centre of the mix alone and leave the sides untouched. The result is dense, heavily processed material that loses neither width nor air despite the amount of reduction.
The valve itself as the gain control
A variable mu circuit has neither a VCA nor an optical cell. Gain changes through the bias voltage of remote cutoff valves, so the reduction is not applied to the signal, it is how the amplifying stage behaves. That produces the characteristic response: the harder you push it, the gentler the curve looks, instead of a hard knee at the threshold. The mode switch gives 1.5:1 in Compress and 4:1 to 20:1 in Limit, attack is continuously variable from 25 to 70 ms, and recovery has five settings: 0.2 s, 0.4 s, 0.6 s, 4 s and 8 s. A high pass filter in the sidechain at -3 dB @ 100 Hz keeps the low end out of the detector so the kick does not drive the whole mix.
