Optional Accessory Installation — VoiceLift System
The Extron VoiceLift system is an easy-to-use, low-power, voice amplification system that ensures the speaker’s
voice can be clearly heard at a comfortable level throughout the classroom. Speech is picked up by the pendant
microphone worn by the teacher and is transmitted via wireless from a base station receiver and the
PVS 305SA IP to the installed ceiling speakers.
For detailed installation information, see the
VoiceLift Installation Instructions, supplied
with the device.
VoiceLift System Included parts:
• VLP 102 pendant microphone
• VLR 102 Receiver
• Wall charger
Installation Procedure
1. Determine the optimal receiver location and
mark and drill a 2.5 inch diameter hole in the
ceiling tile where it is to be installed.
2. Insert the ceiling bracket screw through the back
plate (attached to the housing) and the hole in the
ceiling tile and loosely attach the Z bracket.
3. Align the back plate knockout over the hole in the
ceiling tile and tighten the bracket screw to secure.
4. Replace the ceiling tile.
5. Pull the communication and power RJ-45 Ethernet
cable (and other secondary use cables) through
the receiver base and connect the Ethernet cable
to the Receiver Out port (the RJ-45 connector on
the left on the receiver base).
6. If desired, set the Tone and Mix DIP switches on
the receiver base.
7. Place the dome onto the housing, align the arrows
on the dome locking tab and on the housing rim.
Turn the dome until it locks in place (approximately
1/8 turn).
8. Pull the cables from the receiver to the
PVS 305SA IP switcher location, through the pipe
and down into the PMK 550.
9. Disconnect the power from the switcher, and plug
the included VoiceLift RJ-45 into the
PVS 305SA IP VoiceLift receiver port.
10. Replace power to the switcher. This also powers
the VoiceLift receiver.
