SPL Gemini (Red)

With Gemini, M/S processing enters the SPL Mastering series. Gemini 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. When working on the sum signal, M/S coding often is the best way to specifically get access to individual elements within 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.

An Elliptical Filter, which can cut low frequency ratios of the side band is also provided.

M/S:

The decomposition of the stereo signal in mid (voice, snare, bass ...) and side (guitars, pads, cymbals ...) allows their separate processing.

The center signal (Mid) is the sum of the left and right channel of the stereo signal (L+R), i.e. the "in phase" part of the stereo signal.

The side signal (Side) is the difference of the left and right channels of the stereo signal (L-R), i.e. the "out-of-phase" part of the stereo signal.

Gemini can also be used to enlarge or reduce the stereo image. An elliptical filter for shifting the low frequency component from the side to the mid is also on board.

THE MID:

When the M/S button is activated, the input signal (L/R stereo) is split into a mid and side signals.

The exact center position can be adjusted with the Balance control and the exact level with the Trim control. Both functions are switchable to be in the signal path only when in use.

Exclusive monitoring of the center is possible when the solo function is activated.

Processors can be inserted to process the mid signal and activated with the Insert button.

THE SIDE:

The side signal also has a solo function and a switchable insert for external processing.

In addition, the elliptical filter can be used to shift the bass frequencies from the side to the mid. This improves the punch and precision of low frequencies. The Stereo Width control changes the level of the side signal, with a level increase broadening the stereo image.

These two functions can also be switched on to be in the signal path only when used.

I/OS AND INSERTS:

All inputs and outputs as well as sends and returns are balanced using Neutrik XLR connectors.

Processors can be connected to the inserts for external processing.

Especially interesting is the integration of the Gemini into the Hermes Mastering Router. In this way, processing chains can be created that combine classic L/R processing with M/S processing.

THE 120V TECHNOLOGY:

The 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps.
