The Manley MMSSLCHP is a professionally designed Stereo Variable MU Limiter Compressor Mastering Version made by Manley Labs and it is a dynamic signal processor with the use of a 5670 dual-triode tube intended for peak reduction and compression. The tube is constantly re-biased by the vacuum tube rectified side-chain control voltages, which results in a smooth change in gain. This mastering version is capable of replacing all conductive plastic pots that comes along with Greyhill rotary switches. The 1% metal-film resistors on the Greyhill switches not only capable of providing recallability, but also capable of delivering an improvement in sound quality.

The compressor setting comes offering a soft-knee 1.5:1 ratio, and at the same time the limit mode is capable of offering a sharper knee that comes along with ratios ranging from 4:1 to 20:1. That comes with higher limiting settings, the knee will start to soften. Distortion effects is possible to be achieved by turning up the input and lowering the output and at the same time with the use of little or no compression. The side-chain high-pass filter comes using a 1-pole, 6 dB/octave filter that is capable to attenuate 1 to 3 dB at 100 Hz and 4 to 6 dB at 50 Hz. Once engaged, the compressor / limiter will not respond as strongly to low frequency content and will prevent audible "pumping" by the time the processing bass-heavy music.

The input of the Variable MU is ganged, but still capable of processing two independent channels that comes along with separate threshold and output controls. With the link switch engaged, the unit is possible to operate in true stereo mode and excels at processing 2-track, final mix, or mastering compression and limiting. Handmade in the USA, the unit is housed in a 2U steel chassis with a CNC-machined 1/4" faceplate that is also inlaid with laser-engraved inserts. The Variable MU ships with an IEC power cable.
