4-channel, 1200W Network Amplier
The TesiraXEL1200.1 is an AVB/TSN enabled,
digital networked, four-channel amplier that
allows users to distribute 1-100% of available
power to any channel via a single asymmetric
power bank. The TesiraXEL 1200.1 supports
selectable impedance (4Ω, 8Ω, 70V, or 100V)
and delay equalization per channel.
The TesiraXEL1200.1 is equipped with an
audible locate function on the front panel to
validate connected loudspeaker runs without
requiring the amplier to be congured.
The TesiraXEL 1200.1 comes with a software-
congurable media interface, allowing designers
to choose their preferred network topology.
Redundancy, daisy chain, single-cable, or
separate control and AVB are all supported.
The TesiraXEL 1200.1 also supports 802.1X
authentication for added security requirements.
Features
• 100% asymmetrical loading per channel
• Selectable impedance per channel: 4Ω, 8Ω, 70V, 100V
• Congurable media interface
• Audible locate
• Congurable via Tesira Software
• Auto standby mode
• Delay equalization per channel
• Port authentication via IEEE 802.1X
Asymmetric Power Bank
The TesiraXEL 1200.1 amplier features a single Asymmetric Power Bank which allows
customized distribution of power to loudspeaker channels, allowing for greater exibility and
e󰀩ciency in sound system design.
Network Interface
The TesiraXEL 1200.1 amplier is equipped with two network interface ports (RJ-45
connectors) that may be congured as a redundant pair, separated media network and
control, or used for daisy-chaining multiple devices.

1. Ventilation Fan Cover
The amplier has a perforated cover to allow cool air
into the chassis. Two variable speed, temperature-
controlled fans allow air to circulate through the unit
from front to back.
2. Front Control Panel
The amplier front panel displays information about
the amplier status as well as allowing numerous
functions for conguration and operation.
The front panel may be locked or unlocked by
pressing and holding any two single-channel mute
buttons simultaneously for two seconds. The front
panel may also be locked in software, but doing so
will disable the ability to unlock the control directly
from the front panel.
3. Per-Channel Mute Buttons
Each audio output channel may be muted
individually. A red LED will indicate when a channel
is muted. Holding any mute button for two seconds
will activate or deactivate the mute-all function.
Amplier Front Panel
4. LED Status Indicators
Per-channel and overall system status is indicated
by multi-colored LEDs on the front panel. Table 1
gives information about the status LED indications
and table 2 gives information about the per-channel
LEDs.
5. Locate
Pressing the locate button will play an audible signal
that cycles through each connected output. Device
status LEDs will ash green when locate is initiated.
6. Mute All
Pressing the mute all button will mute all audio on
the amplier.
7. Power Status
The amplier has two power states that may be
enabled or disabled from the front panel: Operating
and Sleep. In sleep mode the amplier will not be
discoverable nor will it respond to network tra󰀩c.
Uncongured devices will not enter sleep mode.

1. AC Power Connection
Allows for connecting an appropriate power cord.
Each amplier uses a switch mode power supply
that has an operating voltage of 100-240V at 50/60
Hz.
CAUTION
Do not remove or defeat the ground prong on the power
cord, as this will constitute a shock hazard. Equipment
should be connected to a mains socket outlet with a
protective earthing connection. This plug is the main
disconnecting device and should remain readily operable.
There are no user interchangeable parts. Please contact
Biamp Technical Support or your local distributor for all
service requirements.
2. Combined AVB/Control Ports
Two gigabit RJ-45 ports allow connections for
numerous network topologies. Ethernet cables must
be Cat 5e or better.
Supported network topologies are documented at
support.biamp.com

3. Logic IO
A standard 6-pin logic I/O may be used as a general
purpose logic I/O as well as allowing the amplier to
enter or exit sleep mode. Functions are dened in
the Tesira software. The illustration below gives the
GPIO pin functions:
4. Amplier Output Connections
Four powered speaker connections allow for audio
output. Mating plugs are included.
To minimize power loss, use a speaker cable of
appropriate gauge for the load impedance. For long
speaker cables, choose a low capacitance cable to
minimize high frequency loss.
If stranded speaker wire is used, be sure to
incorporate all strands into the connector. Stray
strands can short to the adjacent terminal or chassis.
Do not leave excessive bare wire outside the
terminals, as this can lead to shorts. Ensure wire
insulation is not crimped by the screw terminal.
Amplier Rack Installation
The TesiraXEL 1200.1 model amplier is a
standard rack-mount device which requires 2 RU of
installation space. Always install the lower chassis
rack-mount screws rst (and remove last) as shown
in the illustrations on the following page.
CAUTION
Do not exceed the ambient operating temperature of 95°
F (35°C). Be aware of conditions in an enclosed rack
that may cause the temperature to exceed ambient room
conditions.
