d. Test the controller’s configuration with the following:
• Check that the MLC is controlling the PVS 305SA
switcher and projector, and output’s the correct
image when switching inputs.
• Check the projector’s power control (turn it off
and on at the MLC controller).
• Adjust the configuration as necessary.
e. Adjust the audio input sensitivity as follows:
• Ensure there is an audio source at each transmitter.
• Set the MLC controller’s volume to maximum.
• On the PVS 305SA switcher, set the volume for each
input by selecting an input and rotating the Volume
encoder to a comfortable maximum level, i.e., 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 PVS 305SA
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. Refer to the VoiceLift Users Manual for details.
N The MLC volume control does not control the
VoiceLift volume.
By default the switcher has been configured
properly where the input level adjustment and
VoiceLift input adjustment may not be required.
g. Where installed, if necessary, 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. Refer to the Priority Page Sensor Installation
Instructions for full details.
N The Paging Sensor feature must be enabled using
the MLS Configuration software or SIS commands
prior to adjustment.
4. Final installation
a. Slide the covers of the PMK 550 onto the base plate,
ensuring the power cable can exit the unit through the
power cable access slot.
b. Using a 5/32 inch hex wrench, tighten down the four
screws on the PMK 550 to secure the sides in place.
c. Check and tighten the adjuster plate locking screws on
the projector bracket.
d. Hole plugs can be used to cover any exposed holes in the
slotted pipe if necessary.
