Contributing to the ongoing debate about M/S Mastering, SPL introduces a new, powerful analog tool that can manage M/S signal separation and integrate external processors seamlessly - The M/S Master. It's world premiere will be at the Musikmesse in Frankfurt. The M/S Master allows a fully adjustable separation of stereo L/R signals (X/Y) into middle/side signals (M/S). M/S separation and positioning, as well as the stereo image, are defined by the Balance and Level knobs, while a switchable frequency filter for the Side signal controls the lower frequencies and the room ambience. One of the main features of the M/S Master is that it can integrate external processors via switchable inserts. Thus, outboard gear can be easily integrated into the X/Y or M/S mix with a single button and without the need of any cabling. These processing possibilities make the M/S Master an essential tool in mastering environments. The M/S Master will be displayed at the Musikmesse in Frankfurt from the 24th to the 27th of March, 2010. You can find the SPL stand (B82) in Hall 5.1. M/S Mastering
The use of a middle (M) and a side (S) signal instead of the usual L/R (X/Y) signal results in a much more selective and musical processing. High-energy Middle signals (vocals, snare, bass guitars, etc.) can be easily separated from Side signals (guitars, keyboards, cymbals, etc.). Thus, a compressor can be used to process one element instead of the whole mix. The same applies to any kind of processing, making the M/S matrix an indispensable element in the mastering stage.
