AMP-450P Amplifier
Installation & Operation Guide
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 or mounted directly to the Desono C-IC6 speaker with the
BPAK mounting kit.
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.
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.
INSTALLATION
Install away from heat sources, such as vents, radiators, heat registers and stoves. Also avoid installing near water or steam. The amplifier has a secondary support point via chain or wire for connecting to the building structure. Do not exceed the maximum ambient operating temperature of 32° – 104° (0° – 40° C).
FEATURES
- Four channels; 3 watts of continuous power per channel
- Burst mode to handle peak signals in accordance with ANSI/CTA-2006-B; supports up to 50 watts (4Ω load) or 30 watts (8Ω load) per channel
- Powered by PoE+ (IEEE 802.3at Class 4, 30W)
- Class D amplifier topology
- Fan-less operation
- Includes internal limiter function
- Software-selectable power versus channel count
- Evaluated to the requirements of UL 2043 and is suitable for use in air handling spaces
- LED indicators for power and amplifier status
- Configurable via Tesira software
- Can be mounted directly to the C-IC6 speaker with the BPAK mounting kit

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. -

Amplifier Output and Wiring
The amplifier can be configured in either single channel, two-channel or
four-channel mode in the Tesira software. Any unconfigured channels will not
pass audio even if speakers are connected.

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.
Newer versions of the AMP-450P (Sept 2018 or later) come equipped with clips
that can secure the AMP-450P above a ceiling tile to the ceiling “T-bars.”
General Mounting and Installation Notes
- 330 feet (100 meters) maximum from the Ethernet switch to the AMP450P
- Flange pre-drilled for seismic cable installation
- Includes ceiling T-bar mounting clips (x2)
Seismic Cable Installation (optional)
To install the optional seismic cable, place the unit in the desired location:
-
Feed the seismic cable through the hole in the AMP-450P mounting flange as shown in Figure 5.
-
Feed the cable through one end of the locking mechanism as shown in Figure 6.
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. -
Attach the loop to a secure location and apply sufficient tension for minimal slack.
-
Make sure the ends of the lock mechanism are in the locked position (out) as indicated by the blue arrows as shown in Figure 6.
T-Bar Clip Installation
If using clips to install the AMP-450P above a ceiling tile, do the steps that follow:
- Remove ceiling tiles adjacent to the mounting location as required for access.
- Install the clips onto the notched fittings on top of the AMP-450P as shown in Figure 7.
- Fit the clips over two perpendicular T-bars (in the corner) above the ceiling title with the AMP-450P oriented as required.
- NOTE: If installing a TB-1 tile bridge (typically installed to accommodate TCM or DCM model plenums and microphones) the AMP-450P may be mounted to any edge of the ceiling T-bar and the TB-1. See the TB-1 and/or TCM-1 installation manuals for more information at https://www.biamp.com/downloads.
BPAK Clip Installation
The BPAK Backpack Clip Kit allows a Tesira AMP-450P to be attached to the top of a Desono C-IC6 back can.
