User manual BIAMP BI-MIX

[. . . ] The Controller overrides all similar commands which might be initiated from the front panel of the SPM412e (see NOTE below). To install Controller, first remove mounting box from circuit board & front panel. Three screw terminals on circuit board (`GND', `IR2', & `IR3') correspond to `Remote' terminals on rear panel of SPM412e. [. . . ] Use conductors to connect `IR2' to `IR2' and `IR3' to `IR3'. The Controller has seven buttons which control functions on the SPM412e. The Channel Select buttons & indicators provide the same functions as Channel Select on the SPM412e front panel (including the ability to select more than one stereo line input at a time). The Main Level buttons and display provide the same functions as Main Level on the SPM412e front panel, except that only a single indicator will light to display the level setting, and it will dim when the output is muted. NOTE: Two additional screw terminals (`GND'& `KEY SWI') allow an external key-switch (or contact-closure) to `lock-out' control of Channel Select and/or Main Level functions. These functions will then be temporarily available from the SPM412e front panel, as long as the `lockout' is maintained. When `lock-out' is released, the Controller memory will then reassert its previous settings on the SPM412e. The `VOL' DIP switch disables both push-button and infrared control of Main Level. (NOTE: DIP switches must be pushed to the right to achieve the functions described above. ) If Channel Select and/or Main Level control is disabled via the DIP switches, it may be re-enabled via the key-switch. The `N. O. ' DIP switch selects either a `normally open' or `normally closed' keyswitch operation. When this DIP switch is pushed left, a `normally-open' key-switch must be turned ON (shorting `KEY SWI' & `GND' terminals) to re-enable Channel Select and/or Main Level control. When this DIP switch is pushed right, a `normally-closed' key-switch must be turned OFF (`KEY SWI' terminal not grounded) to re-enable Channel Select and/or Main Level control. Install the front panel in the mounting box, using the four screws provided. Appropriate indicators on the face plate will light when power is delivered to the Controller.
