Manual
d.  Test the controller configuration as follows:
• Check that the MLC is controlling the projector 
and PVS 305SA IP switcher, and outputs the 
correct image when switching inputs.
• Check the projector power control (turn it off 
and on at the MLC).
• Adjust the configuration as necessary.
e.  Adjust the audio input sensitivity as follows:
• Ensure there is an audio source at each 
transmitter.
• Gradually set the MLC volume to maximum.
• On the PVS 305SA IP switcher, set the volume 
for each input by selecting an input and rotating 
the Volume encoder to a comfortable maximum 
level, where the input “normal” LED flashes, 
indicating the level is set properly. This ensures 
there is no clipping if the MLC volume is turned 
to maximum during operation.
• Repeat step e for all inputs. 
f.  Where installed, to adjust the microphone 
sensitivity switch on the microphone, press and 
hold the volume down button until no beeps 
are heard from the speakers. Then press and 
hold the volume up button until six beeps are 
heard. To adjust the VoiceLift audio output level 
rotate the VoiceLift encoder on the switcher to 
the “normal” setting and the LED lights. Test 
and adjust the microphone so that the amplified 
voice is heard just above the normal voice level 
at each speaker location. See the VoiceLift User 
Guide for details. 
NOTES: 
• The MLC volume control does not 
control the VoiceLift volume.
• By default the switcher has been 
configured so that input level and 
VoiceLift input adjustments may not be 
required.
g.  Where installed, it may be necessary to adjust 
the sensitivity of the Priority Paging system. 
During a test transmission of the paging system 
rotate the Paging Sensor encoder until program 
audio is no longer heard from the PoleVault 
speakers. See the Priority Page Sensor 
Installation Instructions for full details.
NOTE:  The Paging Sensor feature must 
be enabled using the MLS Configuration 
software or SIS commands prior to 
adjustment.
