PVS 204SA Switcher • Operation and Setup

Setting Up and Optimizing the Audio

The following steps ensure optimal sound is achieved by configuring the  

PVS 204SA properly.  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 50%.
•  Bass and treble are set at 0.
•   Power Amplifier level is set to 50% (default level is 0 dB).
•  Loudness control is set to Off.

N

  Amplifier level and volume level are 

not

 the same adjustments.  Volume can 

only

 be adjusted by RS-232 or with a potentiometer connected to the rear panel 

port labeled “DC Vol”.  Amplifier level is adjusted via the front panel encoder.

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 204SA.  See chapter 2, 

“Installation”, “Speaker Configuration” section, for details.

4

. 

Slowly adjust the volume to 100% via RS-232, by having the MLC increase 

the volume, or by a potentiometer connected to the DC Volume port on the 

rear panel.  If an MLC 104 IP Plus is connected to the PVS, simply rotate the 

volume knob clockwise until it is at full volume.

5

. 

Adjust the input sensitivity for one input through the front panel or by 

RS-232 to a level just below where audio input is clipped.  See the sections  

“Individual channel input sensitivity control” and “Clipping indicator”, later 

in this chapter, for details.  Repeat for all four inputs.

N

  Adjusting input sensitivity for all inputs ensures that all inputs are at the same 

level, and at the highest level possible before clipping occurs.  Step 5 ensures that 
when the volume is at 100%, the audio signal will not clip.

6

. 

When adjustments to all four inputs’ sensitivity settings have been made, 

adjust the amplifier level.  Increase or decrease the amplifier level very slowly 

by turning the front panel level encoder counterclockwise until the desired 

level is reached.

N

  If the volume is at 100% through the MLC and the output on the speakers is too 

loud, reducing the amp level using the front panel encoder is recommended.  This 
ensures that the volume will not be too loud, even when set at 100%.

7

. 

Fine tune the audio by making adjustments to the bass, treble, and loudness 

until the desired settings are reached.  See “Bass, treble, and loudness 

control”, later in this chapter.
