Extron Electronics PoleVault Digital Switcher Systems PVS 405D - Manual (Page 70)

d. Test the controller configuration as follows:
•
Check that the MLC is controlling the projector
and PVS 405D 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.
•
On the PVS 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 is lit,
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, and page 66 of this 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.
õ
Test the MLC configuration is correct.
