Introduction
About this Manual
This manual covers the installation, operation, and configuration of the Extron
PVS 204SA PoleVault ™ Switcher. Throughout the manual, this switcher is
interchangeably referred to as the PVS 204SA, PVS switcher, PoleVault switcher,
PVS, and switcher.
About the PVS 204SA
The Extron PVS 204SA is a four input, two output, twisted pair, audio and video
switcher with a built in audio amplifier. This switcher is comprised of two
independent, built in switchers (a 2 x 1 RGB video and audio switcher and a 2x1
composite video and audio switcher), that allows the PVS 204SA to accept high
resolution (RGB) video and audio, and composite video and audio signal inputs,
along with a line level mono audio auxiliary/mix input. The PVS 204SA is part
of the PoleVault System, a cost effective system with easy cable installation for
transmission of video and audio signals, that is used in conjunction with the Extron
PVT series of transmitters and Extron speakers.
The PVS 204SA can be easily installed at ceiling level using the Extron Pole Mount
Kit (PMK 450) as part of the Extron PoleVault system.
The PVS switcher receives the video and audio signals sent from PVT transmitters,
which can be located up to 100' (30 m) away. The signals can be sent over Extron
Enhanced Skew-Free ™ A/V UTP cable, or any CAT 5, 5e, or 6 shielded twisted pair
(STP), unsheilded twisted pair (UTP), or foil shielded twisted pair (FTP) cable.
The PVS switcher can be controlled from either the front panel buttons, an RS-232
control, an IR remote, or a MediaLink controller.
The PVS 204SA’s built-in 2-channel power amplifier outputs up to 13 W on 4 ohm
load per channel or 7 W with 8 ohm loads as stereo or dual mono audio. Volume
control is made via the front panel, RS-232 , IR, or an Extron VCM control.
Various front panel controls allow the user to adjust the Aux/Mix volume
(independent from input gains, power amplifier gain, and volume) and global
control of the power amp level adjustments.
RS-232 control allows the user to adjust the individual channel gain, limiter on/off
settings, loudness on/off settings, and bass and treble adjustments.
A dual DIP switch allows the user to switch between stereo and dual mono mode
outputs, and to switch the high pass filter on or off.
TP cable advantages
Twisted pair cable is smaller, lighter, more flexible, and less expensive than
coaxial cable. Termination of TP cable with RJ-45 connectors is simple, quick, and
economical. See chapter 2, “Installation”, “A/V input connections” section, for
wiring details.
N For PVT transmitter installation and connection, consult the user’s manual
supplied with the transmitters.
