PVCA 452 • Setup Guide

IMPORTANT NOTE:

Go to www.extron.com for the complete user guide, installation instructions, and specications

before connecting the product to the power source.

The PVCA 452 is an audio and VoiceLift amplier designed for classroom applications. It features an integrated high performance

control processor for centralized AV control and a powerful 2-channel 50W amplier. The PVCA 452 accepts analog and digital

audio signals, and includes dedicated ports for connecting the Voicelift Pro system and optional Page Sensor unit for facility

communications.

NOTE: For full installation and operation details, see the PVCA 452 User Guide, available at www.extron.com.

Inputs

NOTE: The audio input sources (TOSLINK or analog stereo input) are mixed with VoiceLift and aux audio inputs. The TOSLINK

and stereo analog audio inputs are selectable (not simultaneously mixed). The default mode is “Autoswitch” which automatically

switches between the two inputs upon signal detection. The 5-pole analog stereo input has priority over TOSLINK.

APower input — Connect the provided power supply to this 2-pole captive screw

connector. Wire the connector as shown at right.

ATTENTION:

• Do not connect the power supply before reading the Attention in the

Power Supply section of the PVCA 452 User Guide.

• Ne branchez pas la source d’alimentation externes avant d’avoir lu les

mises en garde dans la section « Power Supply » du PVCA 452 User

Guide.

NOTE: Use only the 12 V, 4.2 A power supply supplied with this amplifier. The

PVCA 452 power supply can support a typical system (for example, a

PVCA 452, 2 or 4 speakers, an EBP 100, and a VoiceLift Pro Microphone

system).

Outputs

FLine audio output — Connect a downstream audio

device, such as an external amplifier, unified communication

platforms, recording or assistive listening device to this

3.5 mm captive screw 5-pole connector. It can be wired as

balanced or unbalanced.

GAmplified audio output — Connect

speakers to this 5 mm captive screw

4-pole connector (shown below). The

amplified audio is capable of outputting

50 watts (2 x 25 watts RMS) for 4 and 8

ohm speakers.

To terminate the cable, strip the end of

the cable 0.2 inch (5 mm) and secure

the wires into the supplied 4-pole captive

screw connector as shown below.

HHDMI/CEC/ARC — Supports HDMI ARC (Audio Return Channel) audio and CEC (Consumer Electronics Control) over an

HDMI cable when connected to a display that supports these features. When configured, this allows the display to send its

audio, over the HDMI cable, to the PVCA 452.

Connect the rst eBUS device to this port, then connect other

eBUS devices and accessories to that device in the desired

topology (daisy chain, star, or combination).

• Wire the connectors the same at both ends for every eBUS

device.

• See the eBUS Technology Reference Guide for the

recommended distance from the control processor to the last

eBUS device and maximum quantity of devices per control

processor.

• The PVCA 452 provides 3W of power, which can be used to

power eBUS button panel devices.

PVCA 452 Configuration

The PVCA 452 amplier can be controlled and congured using Extron Product Conguration Software (PCS),

Global Congurator Pro/Plus (GCP), and ToolBelt via a host computer. Firmware updates can also be made using PCS.

• PCS is used for setup and adjustment of PVCA 452 A/V functions. For information on accessing PCS, see the PVCA 452 User

Guide (available at www.extron.com). For configuration details, see the embeded help file in PCS.

• For Global Configurator Pro/Plus, see Configuring the PVCA 452 using Global Configurator below.

NOTE: The factory configured password for this device has been set to the device serial number. Passwords are case sensitive.

Performing a reset to factory defaults sets the password to extron (see the PVCA 452 User Guide for reset instructions).

Conguring the PVCA 452 using Global Congurator

NOTE: The following are the most basic steps, outlined in the recommended order. For detailed instructions, see the Global

Configurator Help File. The help file includes an introduction to the software, and instructions on starting a project.

1. Connect the host computer and the PVCA 452 to the same Ethernet subnetwork (see LAN port on page 4).

2. Start Global Configurator Pro/Plus (GCP) and open the Toolbelt feature (or use the stand-alone Toolbelt program).

3. Start Device Discovery, and select your PVCA 452 device from the list (use the MAC address to locate the desired device).

Enter credentials, if required.

4. Use the Set IP feature in the Toolbelt software, or use the Toolbelt Manage >Network Settings tab to set the IP address or

host name, subnet, gateway IP address, and related settings.

NOTE: If using a host name instead of an IP address, the user must enter a qualified host name

(Username.HostName.Domain). For example: somename.somedomain.com.

5. Using GC, create a new GC Plus or GC Professional project and configure the PVCA 452:

a. Configure the control ports.

b. Select device drivers and link them to each assigned serial, IR, or Ethernet port.

c. Configure settings (serial protocol, relay behavior, digital input, volume control settings) as needed.

d. Add and configure control interface (eBUS, TouchLink Pro, etc.).

e. Set up monitors, schedules, macros, and local variables.

6. Save the project.

7. Build and upload the system configuration to the controller.
