AMP-450P PRODUCT DESCRIPTION
The AMP-450P is a four-channel AVB PoE+ amplifier for use in Tesira® systems. The output channels are software
configurable including selectable power versu s channel count. PoE+ power allows the AMP-450P to be placed wherever
you need it. Suitable for air-handling spaces, t he am plifier can be located close to ceiling speakers if desired. The AMP450P includes an internal limiter and can provide 3W RMS of continuous power to all four channels. The Tesira AMP450P is also capable of operating in a “burst” mode to support higher power levels for dynamic content for brief period s.
The amplifier serves as a dedicated endpoint in a T esira system, making installations easier to design, support and
maintain. The AMP-450P is ideal for Tesira-equipped conference rooms and other applications.

AMP-450P SETUP AND USE
Setup and Use
The Tesira software provides an intuitive interf ace f or setup and programming of the AMP-450P. The information supplied
by this manual relates to physical connections and device setup. For more details on software setup, please consult the
Tesira Help File. For device specifications please consult the AMP-450P Datasheet.
The Tesira AMP-450P does not connect to Telecom Network V oltage (TNV) circuitry and is considered a Network
Environment Zero device.

Facilitates connection to the Tesira AVB network for audio and control. This RJ-45 port may either be connected
directly to the Tesira AVB port (via a PoE+ injector) for a single device system or via a PoE+ network swit c h in a
multi-device AVB system. IEEE 802.3at Power ov er Ethernet Plus (PoE+) Class 4 is required as there are no
other provisions for power inlet.

AMP-450P INSTALLATION
Mounting & Installation
Flanges on each side of the unit have mounting holes to secure the AMP-450P with hardware (not provided) if desired. An
optional seismic cable may be installed through t he center hole on the left mounting flange in lieu of hardware mounting.
Installation Distance Requirements:
• 330 feet (100 meters) maximum from the Ethernet switch to the AMP-450P.
To install the optional seismic cable, place the unit in the desired location:
1. Feed the seismic cable through the hole in AMP-450P mounting flange.
Figure 5 AMP-450P Seismic Cable Mounti ng
2. Feed the cable through one end of the locking mechanism.
NOTE: The ends indicated by the blue arrow need to be depressed to allow the cable to pass through. Internal
guides ensure the cable will be routed through the co rrect path.
3. Attach the loop to a secure location and apply sufficient tension for minimal slack.
4. Make sure the ends of the lock mechanism are in the loc ked position (out) as indicated by the blue arrows.
