Setting Up and Optimizing the Audio
The following steps ensure optimal sound is achieved by configuring the switcher. For
each step, refer to the sections indicated for more information.
Steps for Optimizing the Audio
1.
Ensure all the settings are at default. These are the settings the PVS has upon initial
power up. The default settings are as shown below.
• Volume is set at 80%.
• Bass and treble are set at
0
dB.
NOTE:
Output volume can be adjusted via USB, Ethernet, RS-232, or
configuration software.
2.
Ensure that the PVT transmitters are connected to the PVS and that there is an audio
input source present at each of the transmitters. Refer to the transmitter user guide
for installation and connection information.
3.
Ensure a set of speakers is connected to the PVS 407D.
4.
Adjust the input gain level for one input through the front panel or by configuration
software to a level just below where audio input is peaking (see
on page 16 for details). Repeat for all inputs.
NOTE:
Adjusting input gain level for all inputs ensures that all inputs are at the
same level, and at the highest level possible before peaking occurs. Step 4
ensures that when the volume is at 100% the audio signal is not distorted
(clipped).
5.
Fine tune the audio by making adjustments to the bass and treble until the desired
settings are reached (see
6.

using the buttons to the level desired (see
Front panel input sensitivity adjustment
on page 16 for details). Aux input can be adjusted via PCS.
