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.
