Setting the Output Audio Level

The audio level for each output can be set only via the RS-232 port, using either SIS commands or the Matrix Switchers Control Program (see the “Remote Operation”section). The available settings are professional level (+4 dBu) and consumer level (–10 dBV). The default is professional level.

Front Panel Security Lockout (Executive Mode)

The MVX Series switchers have a front panel security lock feature (Executive mode) that limits the operation of the switcher from the front panel and optional IR remote control. When the switcher is locked, the Enter button, I/O button (video, audio, or video and audio selection), and all of the front panel audio gain and attenuation functions are disabled. The front panel input and output buttons continue to allow ties to be viewed, but ties cannot be created.

The front panel security lockout also disables the IR remote sensor to lock out remote control functions.

Toggle the front panel lockout on and off by pressing and holding the Enter and Preset buttons for approximately 2 seconds (see figure 15).
