Product Description
The AMP-450BP is a four-channel PoE+ (IEEE 802.3at Class 4, 30W)
conferencing amplier for use in Tesira®systems. Suitable for air handling
spaces, the amplier is designed to be mounted directly to the back of a
desono™ C-IC6 loudspeaker, minimizing cabling requirements.
Each AMP-450BP comes with an optional enclosure to protect electrical
connections and comply with typical code requirements for above-ceiling
installations. The AMP-450BP includes an internal limiter, and is capable of
providing 3 watts of continuous power to all four channels.
The Tesira AMP-450BP is also capable of operating in a burst mode to
handle peak signals, providing up to 50 watts (4Ω load) or 30 watts (8Ω
load) per channel. The output channels are software congurable, including
selectable power versus channel count.
The amplier serves as a dedicated endpoint in a Tesira system, making
installations easier to design, support, and maintain. The AMP-450BP is ideal
for TesiraFORTÉ®-equipped conference rooms or other applications where
sound reinforcement is needed.
Setup and Use
The Tesira software provides an intuitive interface for setup and program-
ming of the AMP-450BP. 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.
Installation
Install away from heat sources, such as vents, radiators, heat registers and
stoves. Also avoid installing near water or steam. The conferencing loud-
speaker has a secondary support point via chain or wire for connecting to the
building structure. Do not exceed the maximum ambient operating tempera-
ture of 32° - 104° (0° - 40° C).

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 (P0E+)
Class 4 is required as there are no other provisions for power inlet.

desono Speaker Installation
The AMP-450BP is designed to power and mount on top of a C-IC6
desono™ loudspeaker. The AMP-450BP includes an optional cover to
protect Euroblock and RJ-45 connections on the AMP-450BP and desono
loudspeaker.
See Figures 1 through 3 at right. To install the AMP-450BP on the desono
loudspeaker, do the steps that follow:
1. If installed, remove the connector cover from the desono loudspeaker.
2. Place the AMP-450BP on top of the desono loudspeaker. Tighten the
attachment hardware.
3. Connect the loudspeaker to the AMP-450BP with Ethernet cable via the
RJ-45 ports on both devices.
4. Connect additional speaker cabling to the AMP-450BP per design
requirements.
5. If installing the optional AMP-450BP cover, make sure knock-outs are
removed as required.
6. Feed cabling through the knock-outs and install the cover on to the
loudspeaker and amplier.
a. The cover attachs to the AMP-450BP/C-IC6 via clips and a
thumbscrew.
7. Install the speaker per the appropriate desono Installation and Operation
Guide.
