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 input connections

RGB video and audio inputs (“RGB”) — Each RGB input (inputs 1 to 4)

requires the use of two twisted pair (TP) cables, A and B. Using TP cables, connect up to four high resolution computer video and audio sources via PVT wallplates to these eight RJ-45 female connectors. Inputs 3 and 4 need to be

set via software to accept RGB signals (default is composite video).

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.

Labeling the A/V Inputs

Labeling and connecting the A/V input cables

The RGB and composite video input ports on the rear of the PVS 305SA are color coded to aid easy identiﬁcation of the input signal type. A sheet of corresponding colored labels is supplied for the installer to label the cables running from the PVT Wallplates to the switcher. Once the labels are attached to the cables, the signal type transmitted on any cable can clearly be identiﬁed, enabling correct cable connection during installation.

To label the cables,

Peel off the label corresponding to the cable’s signal type (see the table below) and afﬁx it close to one end of the cable.

Labeling the PVT Decora face plates

To help identify the input number and type of signal that any PVT Decora wallplate sends to the PVS switcher when the wallplate is installed, a series of small labels are supplied. A label identifying the transmitted signal type should be afﬁxed to each Decora face plate (top or bottom) where it can easily be seen after installation. This aids the user to connect a device corresponding to the plate transmission signal type, allowing correct input switching at the PVS 305SA.

“Speaker Conﬁguration” section, for details.

. Slowly adjust the volume to 100% via RS-232, by having the MLC increase

the volume, or by a potentiometer connected to the DC Volume port on the rear panel. If an MLC 104 IP Plus is connected to the PVS, simply rotate the volume knob clockwise until it is at full volume.

. Adjust the input sensitivity for one input through the front panel or by

RS-232 control software to a level just below where audio input is peaking. See the sections “Individual channel input sensitivity control” and “Front

panel input sensitivity control”, later in this chapter, for details. Repeat for all

ﬁve inputs.

Adjusting input sensitivity for all inputs ensures that all inputs are at the same

level, and at the highest level possible before peaking occurs. Step 5 ensures that when the volume is at 100% the audio signal will not be distorted (clipped).

6. When adjustments to all ﬁve inputs’ sensitivity settings have been made, then

adjust the ampliﬁer level (via RS-232 only). Increase or decrease the ampliﬁer level very slowly, if needed.

7. Fine tune the audio by making adjustments to the bass, treble, and loudness

Gain control

Individual channel input sensitivity control

Individual channel input gain control adjustments are made by rotating the adjustment knob for the selected input button. The adjustment range is -18 dB to +24 dB, with the default set at 0 dB.

Front panel input sensitivity adjustment

To make sure the right input sensitivity is attained, do the following:

INPUT

If the volume is at 100% through the MLC and the output on the speakers is too

loud, reducing the amp level via RS-232 control software is recommended. This ensures that the volume will not be too loud, even when set at 100%.

until the desired settings are reached. See “Bass, treble, and loudness control” later in this chapter.

Adjusting input sensitivity for all inputs ensures that all inputs are at the same

level and at the highest level possible before clipping occurs. Individual channel input gain levels either adds to or subtracts from the overall

(global) power ampliﬁer gain level per channel.

Upon initial power up of the switcher, the ampliﬁer level is automatically

adjusted to 50%.

. For the active input (with the LED lit), rotate the level adjustment knob until

the Normal LED blinks.

Having the audio level beyond the point at which the peak LED ﬂashes results in

a distorted output signal (clipping).

Bass, treble, and loudness control

For optimum audio quality, the audio input levels and the bass, treble, and loudness controls must all be set up properly. Input audio levels may need to be adjusted depending on the variation of the output levels from different source devices.

PRELIMINARY

By default these levels are set for the consumer product level of -10 dBV.

Bass and treble should be adjusted once the input and output levels have been adjusted. These are adjusted by RS-232 control only, with a range from -10 dB to +10 dB. By default the bass and treble have been set at 0 dB. See chapter 4, “Serial

Communication”, for details on RS-232 control.

The loudness on/off (default off) switch function is also controlled by RS-232.

The PVS 305SA switcher can be remotely set up and controlled via a host computer or other device (such as a control system) attached to the rear panel Control port. Alternatively, the switcher can be controlled by an MediaLink Controller (MLC) (connected to the same port) or by an RS-232 device acting through the MLC. The control device (host) can use either the Extron Simple Instruction Set (SIS program for Windows. For details on use and setup of a system that includes a MLC, refer to the MediaLink Controller user’s manual.

Host-to-PVS communications

SIS commands consist of one or more characters per ﬁeld. No special characters are required to begin or end a command sequence. When the PVS switcher determines that a command is valid, it executes the command and sends a response to the host device. All responses from the switcher to the host end with a carriage return and a line feed (CR/LF = ]), which signals the end of the response character string. A string is one or more characters.

Error responses

When the PVS switcher receives a valid SIS command, it executes the command and sends a response to the host device. If the PVS is unable to execute the command because the command is invalid or it contains invalid parameters, it returns an error response to the host.

The error response codes and their descriptions are as follows: E01 – Invalid input channel number (too large)

E06 – Invalid channel change E10 – Invalid command E13 – Invalid value (too large) E14 – Invalid command for this conﬁguration

Using the command/response tables

The command/response tables in this chapter list valid command ASCII codes, the PVS’s responses to the host, and a description of the command’s function or the results of executing the command. Upper and lower case characters may be used interchangeably in the command ﬁeld unless otherwise speciﬁed (setting gain/ attenuation, for example).

The ASCII to hexadecimal (HEX) conversion table below is for use with the command/response tables.
