The hard reset restores the factory-installed firmware. The switcher reverts to
that factory firmware the next time power is cycled off and on unless a
firmware update is performed before the power cycle.
If necessary, turn off power to the switcher.
Press and hold the Reset button on the rear panel while you apply AC power
to the switcher (figure 3-81).
Press and hold the Reset button while you apply power to the
switcher.
The switcher flashes the button indicators green,
red, and amber and then turns them off.
Continue to hold the Reset button until all input and output buttons return
to either unlit or to background illumination and the RGBHV or Video and
Audio buttons turn on.
NOTE
The Reset button on switchers with matrix sizes of 24 x 12 and above
have a different appearance and do not have a rear panel Reset LED.
Connect audio sources to all desired inputs and connect the audio outputs to
output devices such as audio players. See Audio input and output connections
(audio models only), in chapter 2, Installation. For best results, wire all of the
inputs and the outputs balanced.
Power on the audio sources, the switcher, and the audio players.
Switch among the inputs (see Creating ties, in this chapter), listening to the
audio with a critical ear or measuring the output audio level with test
equipment, such as a VU meter.
As necessary, adjust the input audio level of each input (see Viewing and
adjusting the input audio level (audio models), in this chapter) so that the
approximate output level is the same for all selected inputs.
As necessary, adjust the output audio level of each input (see Viewing and
adjusting the output volume (audio models), in this chapter).
