About this listing
The SPL Gemini Mastering M/S Processor is an M/S Encoder and Decoder. Mid signals (voice, snare, bass …) can clearly be seperated from side signals (guitar, spatial sounds, cymbals …) and can individually be processed.
The Gemini is the first mid/side processor in 120V technology. In mastering, M/S processing is often the best way to get targeted access to individual elements of a mix. Gemini also provides the possibility to work on the stereo panorama. With the Balance control you can position the mid signal within the stereo panorama. With the Trim control, you can adjust the level of the mid signal in relation to the side signal. In connection with the Stereo Width control, the mixing ratio of both channels can be adjusted.
M/S with Gemini & HermesHermes and Gemini operate in their complete range of functions as stand-alone devices. A pairing of Hermes and Gemini enables lots of further possibilities.If the M/S Encoder and Decoder stages of Gemini are each paired with an insert of Hermes, it is possible to freely choose a position for the M/S Encoder and Decoder within the processing chain. This way, it is possible (see image below) to place the M/S Encoder on the third position, an equalizer on the fourth to use it for separate processing of the mid and side signal and then use the M/S Decoder stage of the Gemini on the fifth position to generate an L/R stereo signal. If you now like to additionally use a compressor, as a further device for M/S processing, you can place it on position 5 and the M/S Decoder stage would thus move to position 6.
