TCM-1, TCM-1A & TCM-1EX PRODUCT DESCRIPTION

Tesira TCM-1

The TCM-1 is an AVB ceiling microphone for use in Tesira systems. Comprising a pendant microphone and plenum box,
each microphone includes Beamtracking™ technology with three 120-degr ee zones, providing full 360-degree coverage
of the meeting space. The TCM-1 microphone actively tracks and intelligently mixes conversations from around the table,
allowing far-end conference participants t o experience the conversation naturally. The Tesira TCM-1 comes with its own
digital signal processing module for beamtracking, and each plenum box comes with an additional RJ-45 connector for
daisy-chain connections. A maximum of three microphones are permitted per daisy chain (one TCM-1 required, plus up to
two TCM-1EX).

Tesira TCM-1A

The TCM-1A is an AVB ceiling microphone and PoE+ amplifier for use in Tesira systems. Comprising a pendant
microphone and plenum box, each microphone includes Beamtracking™ technology with three 120-degree zones,
providing full 360-degree coverage of the meeting s pace. The TCM-1A microphone actively tracks and intelligently mixes
conversations from around the table, allowing far-end conference participants to experience the conv ersation naturally.
The 2-channel PoE+ amplifier includes an internal limiter, software configurable amplification, and a “burst” mode to
support higher power levels for dynamic content. The TCM-1A co mes with its own digital signal processing module fo r
beamtracking, and each plenum box comes with an additional RJ-45 connector for daisy-chain connections. A maximum
of three microphones are permitted per daisy chain (one TCM-1A required, plus up to two TCM-1EX).

Tesira TCM-1EX

The TCM-1EX is an expansion ceiling microphone for use with the T CM-1 or TCM-1A in Tesira systems. Comprising a
pendant microphone and plenum box, each microphone includes Beamtracking™ technology with three 120-degree
zones, providing full 360-degree coverage of t he m eeting space. The TCM-1EX provides an expansion microphone for a
TCM-1 & TCM-1A which actively tracks and intelligently mixes conversations from around the table, all owing far-end
conference participants to experience the conversation naturally. The Tesira TCM-1EX is intended to be used as a
second or third microphone in conjunction with a TCM-1 or TCM-1A; it cannot operate as a standalone device. Each
plenum box comes with an additional RJ-45 connector for daisy-chain connections. A maximum of t hree microphones are
permitted per daisy chain (one TCM-1 or TCM-1A required, plus up to two TCM-1EX).

Setup and Use

The Tesira software provides an intuitive interf ace f or setup and programming of the TCM-1, TCM-1A and the TCM-1EX.
The information supplied by this manual relates to physical con nections and device setup. For more details on software
setup, please consult the Tesira Help File. For device specifications and m i crophone polar pattern please consult the
datasheet.

The Tesira TCM-1, TCM-1A and TCM-1EX do not connect with Telecom Network Voltage (TNV) circuitry and are

considered Network Environment Zero devices

for use with TCM-1, TCM-1A and TCM-1EX

1. AVB/Control
Facilitates connection to the Tesira AVB network for audio transmission 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. The TCM-1 is an IEEE 802. 3 T ype 1 Class 3 PoE device requiring

15.4W of PoE power. The TCM-1A is an IEEE 802. 3 Type 2 Class 4 device requiring 30W of PoE+ power. There
are no other provisions for power inlet.

2. Mic (IN)
Allows up to two additional TCM-1EX expander microphone units in a daisy-chain topology. Use of this RJ-45 port
is optional and will depend on the number of additional microphones required to cover the acoustic space.

3. Power LED
A multi-color LED provides information about the status of the device.
