between -18 dB and +24 dB, and affect both left and right
channels equally.

The Changes: Immediate and Changes: Verify

are applied to the switcher. In Immediate mode, every
change (including each audio gain step) is instantly
written to the unit. In Verify mode, the changes made
on screen are not applied until you click the Take button
(which is enabled when verify mode is chosen) and may
be cancelled at any time before pressing Take.

defaults, click on the Use Defaults button.

Front panel security lockout

If the switcher is installed in an accessible area, where operation
by unauthorized personnel may be a problem, a security
lock-out feature can be implemented. When the front panel
is locked, it cannot be operated. Either an RS-232 command
or front panel operation (press and hold the Output and
Confi guration buttons for 3 seconds) is required to unlock the
front panel before it can be operated.
Toggle the front panel lock on and off by clicking the Front Panel
Lock Out button in the Universal Switcher Control Program
window.
N
When the front panel is locked, the switcher will still
respond to SIS and control program commands.
