AMP-450P Amplifier
OPERATION MANUAL
APRIL 2018

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 versus channel count. PoE+ power allows the AMP-450P to be placed wherever
you need it. Suitable for air-handling spaces, the amplifier can be located close to ceiling speakers if desired. The AMP-
450P includes an internal limiter and can provide 3W RMS of continuous power to all four channels. The Tesira AMP-
450P is also capable of operating in a “burst” mode to support higher power levels for dynamic content for brief periods.
The amplifier serves as a dedicated endpoint in a Tesira 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 interface for 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 Voltage (TNV) circuitry and is considered a Network
Environment Zero device.

1. AVB / Control
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 switch in a
multi-device AVB system. IEEE 802.3at Power over 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 the 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 Mounting
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 correct 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 locked position (out) as indicated by the blue arrows.

FCC NOTICE
FCC Part 15 –
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this
device may not cause harmful interference and (2) this device must accept any interference received, including
interference that may cause undesired operation.
The following applies to products with a telephone interface:
This equipment complies with Part 68 of the FCC rules and the requirements adopted by the ACTA. On the rear of
this equipment is information that contains a product identifier in the format US:6RMEQ##TXXXX. If requested, this
number must be provided to the telephone company.
This equipment is designed for modular connection with Jack Universal Service Order Codes RJ-14C, RJ-14W.

CAUTION: To reduce the risk of fire, use only No. 26 AWG or larger (e.g., 24 AWG) UL Listed or CSA Certified
Telecommunication Line Cord.
The Ringer Equivalence Number (REN) is used to determine the number of devices that may be connected to a
telephone line. Excessive RENs on a telephone line may result in the devices not ringing in response to an incoming
call. In most but not all areas, the sum of RENs should not exceed five (5.0). To be certain of the number of devices
that may be connected to a line, as determined by the total RENs, contact the local telephone company. For
products approved after July 23, 2001, the REN for this product is part of the product identifier that has the format
US:6RMEQ##TXXXX. The digits represented by ## are the REN without a decimal point (e.g., 03 is a REN of 0.3).
For earlier products, the REN is separately shown on the label.
If this equipment causes harm to the telephone network, the telephone company will notify you in advance that
