IM1

Insert Master module with stereo send and return and mid/side stereo functions

The IM1 Insert Master is an API 500 series stereo module, with added stereo send and return, and mid/side stereo functions.
The mid/side conversion on the insert provides different processing of mid and side signals, with an additional dry/wet crossfader at the return (for parallel processing). There's a 20db boost at the send to pull up quiet signals. There's an extensive monitoring section at L, R, Mid/Side at the insert send and return points. The stereo base can be changed from mono to differential (extra stereo) with a continuous control pot. In addition to that there's dedicated in and output gain controls. An overload indicator at in- and output completes the module.
The module uses a propriety back panel, to house all the connectors. It can be mounted in the Zähl lunchboxes.
