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.
NOTE: Output volume can be adjusted via USB, 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 transmitters’ user’s
manual for installation/connection information.
3. Ensure a set of speakers are connected to the PVS 405D.
4. Adjust the input sensitivity for one input through the front panel or by configuration
software to a level just below where audio input is peaking. See the sections
“Individual channel input sensitivity control” and “Front panel input sensitivity control”,
later in this chapter, for details. Repeat for all five inputs.
NOTE: Adjusting input sensitivity 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 will not be distorted
(clipped).
5. Fine tune the audio by making adjustments to the bass and treble until the desired
settings are reached. See “Bass, treble” later in this chapter.
6. The aux input is selectable for configuration only. To do this press and hold the Select
button for 3 seconds until the Aux LED lights. Then turn the Input encoder to the
level desired. See
Front panel input sensitivity adjustment section on page 13 for
details. Aux input can be adjusted via SIS or PCS.
7. Press the Select button to exit the Aux configuration mode.
