Introduction

About this Manual

This manual covers the installation, operation, and configuration of the Extron
PVS 305SA PoleVault® Switcher. Throughout the manual, this switcher is
interchangeably referred to as the PVS 305SA or PoleVault switcher.

About the PVS 305SA

The Extron PVS 305SA is a five input, two output, twisted pair, audio and video
switcher with a built-in audio amplifier. It is part of the PoleVault System and is
used in conjunction with the Extron PVT series of transmitters and Extron speakers.
The PVS 305SA accepts high resolution (RGB) video and audio, and composite
video and audio signal inputs, and has a dedicated port for connecting the optional
VoiceLift® microphone system.

The PVS 305SA is comprised of two independent, built in switchers (a 4 x 1 RGB
video and audio switcher and a 2 x1 composite video and audio switcher), that
allows the PVS 305SA to accept high resolution (RGB) video and audio, and
composite video and audio signal inputs. It has a separate audio input that can
be switched with the other four inputs. The PVS 305SA is part of the PoleVault
System, a specific cost effective system with easy cable installation for transmission
of video and audio signals, that is used in conjunction with the Extron series of
PoleVault A/V Source Input Wallplates and Extron speakers.

As part of the Extron PoleVault system, the PVS 305SA is installed at ceiling level
within an Extron Pole Mount Kit, the PMK 550. Alternatively it can be mounted in
a WMK 100 wall mount that is installed on a wall close to the projector.

The PoleVault switcher receives the video and audio signals sent from PVT
Wallplates, which can be located up to 100 feet away. The signals can be sent over
Extron Enhanced Skew-Free
twisted pair (STP), unsheilded twisted pair (UTP), or foil shielded twisted pair
(FTP) cable.

The PoleVault switcher can be controlled from either the front panel buttons, an
RS-232 control, an IR remote, or a MediaLink controller.

The PVS 305SA has a built-in 2-channel power amplifier that outputs up to 25 W
at 2, 4, or 8 ohm loads per channel as stereo or dual mono audio. Volume control is
made via RS-232 , IR, or an Extron VCM control.

Various front panel controls allow the user to adjust the independent input gains,
and VoiceLift microphone input level.

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/V UTP cable, or any CAT 5, 5e, or 6 shielded

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.

The PoleVault signal transmission method is specific for PVS 305SA

The PVS 305SA is capable of receiving signals from PVT wallplates located up

to 100 feet (30m) away. The optimum distance is between 50 and 75 feet
(15 and 22 meters). Minimum distance is 15 feet (4.6 meters).

The RGB cables supplied with the PoleVault system are terminated to the
TIA/EIA T568A standard.

If other cables are used the RJ-45 termination must comply with the T568A or
T568B wiring standards (as shown in figure 2-6), and the same standard MUST
be used at both ends of the cables.

The ports on the rear of the PVS 305SA 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.

PVS 305SA Switcher • Installation

When connecting the TP cables to the PVS 305SA, take care not to cross-connect
the cables; connect input cable 1A to the RJ-45 port labeled 1A, and input cable 1B
to the RJ-45 port labeled 1B. Likewise, connect input cables 2A, 3A, or 4A to its
corresponding numbered A port, and cable B to its B port (see figure 2-7).
