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-degree 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 to 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 space. The TCM-1A microphone actively tracks and intelligently mixes
conversations from around the table, allowing far-end conference participants to experience the conversation 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 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-1A required, plus up to two TCM-1EX).
Tesira TCM-1EX
The TCM-1EX is an expansion ceiling microphone for use with the TCM-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 the meeting 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, allowing 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 three microphones are
permitted per daisy chain (one TCM-1 or TCM-1A required, plus up to two TCM-1EX).

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 Type 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.

Example Topologies – Amplifier Speaker Wiring
Figure 7 Amplifier speaker wiring (TCM-1A only)
All speaker wiring connections require Class 2 wiring and should be made by qualified personnel with the amplifier power
removed.
Channel Assignment & Power Ratings
The amplifier can be configured in either single channel or two channel mode in the Tesira software. In 2 channel mode,
outputs 1 & 2 will be active and pass audio. In single channel mode, only channel 1 will be active and pass audio. Channel
2 will not pass audio even if a speaker is connected.

TCM-1, TCM-1A & TCM-1EX INTERNAL CONNECTIONS
Internal Connections
The TCM-1, TCM-1A and TCM-1EX include a folded metal enclosure (plenum) designed for permanent installation on a
ceiling or other horizontal surface, above a ceiling tile, or on a vertical surface. The devices are passively cooled and do
not have ventilation ports.
A 2-pin connector is located on the inside of the plenum to connect the pendant microphone. The connector is keyed to
prevent incorrect polarity. The microphone is designed to be suspended from the plenum by the cable. The length of the
suspended cable is adjustable by pinching the soft plastic on the under-side of the microphone mount. This allows the
cable to be extended or shortened to the desired length.
Figure 8 Pinch-points for Microphone Cable Length Adjustment
Strain relief for the microphone cable should be fitted using the included zip-ties by securing it to either the circuit board
(TCM-1EX) or the circuit board protective barrier (TCM-1 & TCM-1A) inside the plenum. Excess cable may be coiled as
shown in the figures below.
CAUTION: Make sure the cable is not strained or the zip-tie overtightened as damage may occur.
Figure 9 TCM-1 & TCM-1A Figure 10 TCM-1EX
Punch out through-holes in the plenum allow the microphone cable to exit either vertically or horizontally through the
microphone mount. Keyed mounting holes allow installation on a vertical or horizontal surface or above a ceiling tile. The
plenum design allows for an optional seismic cable to be connected.

Seismic Cable (optional)
An optional seismic cable is available for the TCM-1, TCM-1A and the TCM-1EX.
1. To install the seismic cable, locate the holes in the plenum as identified by the arrows. Holes to accommodate the
cable are in similar locations for all TCM models.
Figure 14 Seismic Cable Installation
2. Feed the cable through the hole in the plenum so the end-stop remains inside.
Figure 15 End-stop Installation

3. 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 make sure the cable will be routed through the correct path.
