SPL M/S Master External Processors

SPL introduces a new powerful analogue tool that can manage M/S signal separation and integrate external processors seamlessly.

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 settings, 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 the integration of external processors by using switchable inserts. Outboard gear can be easily integrated into the X/Y or M/S mix without extra wiring and by simply using a single control which is essential in mastering environments.
