Optimizing the Audio (HVA Switchers)

Each individual input audio level can be adjusted within a range of -18 dB to
+24 dB, so there are no noticeable volume differences between sources and for the
best headroom and signal-to-noise ratio. Adjust the audio gain and attenuation as
follows:

RESET
The switcher flashes the LEDs
and then turns them off.
Continue to hold the Reset button until all input and output LEDs return
to unlit and the RGBHV or Video and Audio LEDs turn on.
RESET
A hard reset returns the switcher to the default (factory) firmware
configuration. The switcher continues to operate using this firmware until
you either cycle power, in which case the switcher begins to use the most-
recently installed firmware update, or install a new firmware update.
Connect audio sources to all desired inputs and connect the audio outputs to
output devices such as audio players. See Audio input and output (HV A 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 a configuration, 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 (HV A models), in this chapter) so that the
approximate output level is the same for all selected inputs.
