OPERATING INSTRUCTIONS FOR GAMBIT EQUALIZER EQ1-DYN OPERATION

M/S Mode

A 2-channel stereo signal can be transformed from the L/R (left/right) domain into the M/S (mid/side) domain and back without any signal degradation.

In the M/S domain, the two channels representing the stereo signal contain information on the Mid (mono) and Side content of the stereo signal.

Equalizing in the M/S domain can, for example, just affect vocals or instruments centred in the stereo mix. Or, by boosting the S channel, result in frequency dependent stereo-base enhance- ment.

On/Off

Press the “menu” key, then select the “System -> MS coding” option. This opens the “MS Coding Setup” menu (see Graphic 5).

and the output to L/R – the eq section can be set to either, depending upon which domain one wants to eq.

Another option is encoding a L/R signal to M/S for further M/S processing outside the EQ1-MK2. Then the output will have to be set to M/S and the input to L/R. Again, the eq section can operate in either domain.

To compensate for different non-standardized M/S formats, there is a L/R swap option. This, as the name implies, will swap the decoded left and right channels, and will be used when decoding M/S recorded material to L/R.

The MS mode is activated by toggling the “M/S on/off” value with key C. The M/S icon will ap- pear in the top left corner of the frequency re- sponse window to indicate that M/S mode is ac- tive.

Setup

Several possible M/S configurations can be acco- modated for in the EQ1. This can be achieved with the “M/S Setup” option by pressing key D. The user is then taken through a procedure to specify the setup to be used. The “back” and “next” keys help negotiating within the setup pro- cedure.

To eq a standard L/R stereo signal in the M/S domain, the input and output sections are speci- fied as L/R, while the EQ is set to M/S.

If one decides to decode a M/S recording, for example, the input would have to be set to M/S
