Step 3 — Install the PVS 407D Switcher
The PVS 407D PoleVault Switcher receives input video and audio signals from the AV
source input wallplates, and audio signals from the VoiceLift VLR 302 receiver. It outputs and
switches the video and audio signals to a display and speakers. For details, see the
PoleVault
Digital Systems Installation Guide (Featuring the PVS 407D Switcher) , included with the

PoleVault Switcher Installation
1. Determine a location within the room for the PVS 407D switcher (see PoleValut Switcher
Location below).
2. Install the PVS 407D, following the instructions in the PoleVault Digital Systems Installation
Guide ( Featuring the PVS 407D Switcher) and the provided mounting kit user guide.
3. Make sure that the PVS 407D front and rear panels are accessible until installation and
testing of the VoiceLift System is complete.
PoleVault Switcher Location
The PoleVault switcher can be mounted anywhere in the room. However, placing the switcher
near the ceiling makes cabling and upgrading to a full PoleVault system easier. WallVault
and PlenumVault options are also available for wall or plenum ceiling mount applications (for
installation instructions, see the installation guides for each system).
WARNING: Structural ceiling failure could cause serious injury or death. Check the
structural ceiling to ensure that it can handle a load four times the weight of the final
setup.
AVERTISSEMENT : Un défaut dans la structure du plafond pourrait provoquer des
blessures graves voire mortelles. Vérifier la structure du plafond afin de vous assurer qu’il
peut supporter une charge quatre fois supérieure au poids de l’installation finale.
Possible switcher mounting locations include:
• Table top, cabinet, or shelf (attach the four provided rubber feet to the bottom of the unit)
•
Under a desk
• Mounted to a wall with an Extron WMK 160 or USFM 100 WallVault Wall Mount Kit
• Above a drop ceiling using the Extron PlenumVault PVM 220
