it is assumed that all of the necessary cable
routing has been completed, and that projector
ceiling hardware (e.g. ceiling mounts, projector
poles, projector mounting kits) and output
devices have been installed. Also, any PVT
transmitters should already be installed (but not
yet connected) following the relevant supplied
instruction manuals.
N Labeling the cables correctly using the
color code will make this step easier.
Inputs 1 and 2: RGB video and audio.
N Two cables (A and B) are needed for each
RGB input. Do not cross connect them.
Step 1
Remove power from the switcher and any input,
output, and control devices that are to be used in
this installation.
Step 2
Using the supplied colored labels, label both ends
of all audio/video input cables. Ensure that the
labels used match the input signal type that the
cable will carry. See chapter 2, “Installation”,
“Labeling and connecting the A/V input cables”
section, for wiring diagrams and input color
coding table.
N In some installations it may be prudent to
label the cables before routing them.
Step 3
Connect input devices via PVT transmitters to
the RJ-45 inputs on the rear of the PVS switcher.
See chapter 2, “Installation”, “A/V input
connections” section, for details and wiring
diagrams.

Introduction
About this Manual
This manual covers the installation, operation, and conguration 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
(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 amplier 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.
™
A/V UTP cable, or any CAT 5, 5e, or 6 shielded twisted pair

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.

Mounting the Switcher
The PVS 204SA can be mounted on the Extron PMK 450 (Pole Mount Kit), which
should be installed above the projector. The low prole of the PVS switcher and
the PMK 450 allows them to be installed in tight spaces. To install the PVS 204SA
on the PMK, follow the steps shown in the instruction guide supplied with the
PMK 450. If the PMK 450 is already installed, do the following:
1. Remove the front, rear, and filler plates and separate the top and bottom
plates of the PMK (see gure 2-1).

RJ-45 termination must comply with the TIA/EIA T 568A or 568B wiring
standards for all connectors. The same standard MUST be used at both ends of
all cables.
N
The RGB cables supplied with the PoleVault system are terminated to the TIA
568A standard, as shown in figure 2-4.
Figure 2-4 — Twisted pair RGB video and audio cable wiring.
N
Cable A Video carries the video signals and horizontal sync, and cable B carries
the audio signal, vertical sync information, and 5 VDC current from the PVS to
power the PVT transmitters.
N
The ports on the rear of the PVS 204SA are color coded for input number
and signal type. To ensure correct cable identification and connection during
installation, a sheet of color coded cable labels is supplied. See “Labeling the
A/V Inputs”, later in this chapter, for details on how to use these labels.
N
When connecting the TP cables to the PVS 204SA, take care not to cross-
connect the cables; connect input 1’s video signal to the RJ-45 port labeled 1A,
and input 1’s audio signal to the RJ-45 port labeled 1B. Likewise, connect
input 2‘s video signal to 2A, and the audio signal to 2B (see figure 2-5).
Figure 2-5 — Connect the correct transmitter output cables to the
switcher inputs.
Composite video and audio inputs (”Video”) — Each composite
c
video input needs one TP cable. Using TP cable, connect up to two
composite video and audio sources via PVT transmitters to these
two RJ-45 female connectors labeled 3 and 4; each one is for video
and audio combined.
