REMOTE CONTROL An infrared receiver is provided on the VSX41 front panel, however, infrared and wall-mount remote control is optional. This allows the user to select only the type and quantity of controls necessary for a particular application. Remote controls affect VSX41 Channel Select switching, as well as functions on other ® ADVANTAGE products that might be connected to the VSX41. Remote controls may be added at any time, and do not require the VSX41 to be modified, opened, or removed from a rack.
REMOTE CONTROL Remote Interface Kit (Biamp #909-0041-00): The Remote Interface Kit allows the user to create a customized control panel, using his own switches, enclosure, and panel. It can provide up to 40 buttons (12 more than standard remote controls), which are support by some ® other ADVANTAGE products. The VSX41 itself only supports 4 buttons (Channel Select), but it will also pass commands on to other Advantage products which have been connected to the Remote Output (see Applications on page 7).
OPTIONS NOTE: To access internal jumper options: 1) disconnect the unit from AC power 2) remove the top panel 3) lay the unit with the front panel facing away 4) using needle-nose pliers, move the desired jumper straps as described below 5) replace the top panel. 75 Ohm Back-Termination: From the factory, Inputs 1~4 have 3.9k ohm ’back-termination’, which is appropriate for most applications.
