Cable and Power Requirements
The Biamp TCM‑XA requires a single Ethernet cable that supports IEEE 802.3at PoE, delivering 30 W of power to the unit. Use Cat 6 or higher, with a minimum length of 1 m and a maximum of 100 m to accommodate typical ceiling distances. Shielded twisted‑pair (STP) is recommended when the cable runs near high‑voltage equipment or in a plenum space to reduce electromagnetic interference. The RJ45 port accepts 802.3af and 802.3at; 802.3at is required for full power. The device draws 30 W, which translates to approximately 2.5 A at 12 V or 0.5 A at 48 V. Tesira must provide a PoE injector or switch that supports 802.3at Type 2 Class 4. Ensure the injector’s output voltage is 48 V DC and the current rating exceeds 2.5 A. Connect the injector’s output to the TCM‑XA’s Ethernet port using a short patch cable; the injector’s input should be connected to the network switch. Cable management should follow local codes: secure the cable with ties or conduit, avoid sharp bends, and keep the cable away from heat sources. Verify the cable’s length and power rating before installation, and test the PoE delivery with a PoE tester to confirm 30 W is supplied. Proper cable selection and power provisioning are critical for reliable operation and compliance with UL‑2043 plenum standardsEnsure all connections are secure and verify the PoE power meter reads 30 W to guarantee optimal performance; follow the manufacturer’s guidelines for cable routing, maintain a 10 cm clearance heat source
Beamtracking Setup
The TCM‑XA’s beam‑tracking system divides the 360° field into four 90° zones, each with its own microphone array. During initial setup, the device automatically calibrates by rotating a test source around the room. The Tesira software allows manual adjustment of each zone’s sensitivity and gain. To fine‑tune, open the Beam Zone panel, select a zone, and use the slider to set the desired level. The system supports dynamic re‑balancing when a new microphone is added or removed. For optimal coverage, place the TCM‑XA so that the corners of the zones align with the room’s walls. The device’s firmware continuously monitors signal levels and adjusts the beam‑forming weights to maintain clarity. If a zone receives excessive noise, reduce its sensitivity or reposition the unit. The beam‑tracking feature is fully integrated with Tesira’s audio‑routing, enabling selective zone activation for different meeting scenarios. Remember to lock the firmware after configuration to prevent accidental changes. The TCM‑XA also supports a “smart‑zone” mode, where the system automatically selects the most active zone based on speech activity. This mode is ideal for large conference rooms with multiple participants. Ensure the device is powered via PoE and that the network connection is stable before initiating the beam‑tracking calibration. Once completed, save the configuration and verify the audio quality by speaking from various positions around the room. Installers should also verify that the ceiling tile clearance meets the manufacturer’s e.g. spacing. The beam‑tracking setup is a critical step for achieving the best possible audio performance in any meeting environment.

Configuring Beam Zones
Once the TCM‑XA is on the network, open the Tesira Beam Tracking panel. The microphone presents four 90° sectors; each can be independently tuned. Select the desired sector, then adjust the Gain slider to set the microphone’s sensitivity. The Threshold knob controls the minimum signal level required to activate the beam. Use the Angle control to fine‑tune the sector’s coverage, ensuring that the 360° field is evenly partitioned. After setting a sector, click Apply and repeat for the remaining three. Once all zones are configured, enable Beam Tracking mode. The TCM‑XA will now automatically switch between sectors as speakers move, maintaining optimal audio capture. For advanced users, the Fine‑Tune tab allows adjustment of the Hysteresis and Response Time parameters to reduce chatter. Save the profile and test by walking around the room; the microphone should follow the speaker’s position smoothly. If any sector appears dead or overly sensitive, revisit the Gain and Threshold settings until balance is achieved.

Vestibulum ante ipsum primis in faucibus orci luctus et ultrices posuere cubilia curae; Integer non.
Adjusting Sensitivity and Gain
Fine‑tuning the TCM‑XA’s sensitivity and gain is essential for optimal performance in varied acoustic environments. Begin by selecting the Beam Tracking tab in Tesira, then navigate to the Sensitivity slider. This control sets the microphone’s baseline response to ambient noise. Lower values reduce pickup of distant sounds, while higher values increase overall sensitivity. Next, adjust the Gain knob for each beam zone. Gain determines the amplification applied to the captured signal before it is sent to the network. A higher gain can compensate for low‑level speech, but may introduce clipping if set too high. Use the Meter display to monitor the signal level; aim for a peak around –6 dBFS to maintain headroom.
When configuring multiple zones, it is advisable to set a uniform gain across all sectors to preserve balanced audio. After initial adjustments, conduct a walk‑through test: speak from various positions while observing the meter and listening for clarity. If the signal saturates, reduce the gain by 3–6 dB; if it remains weak, increase by the same amount; Remember that the TCM‑XA’s built‑in digital limiter will protect against sudden peaks, but it is best to keep the input level well below the limiter threshold to avoid distortion.
For advanced users, the Advanced Settings panel offers a Dynamic Range Compression option. Enabling this feature can help maintain consistent output levels in rooms with high reverberation. Adjust the Threshold and Ratio sliders to achieve the desired compression effect. Once satisfied, click Save to apply the configuration. Regularly revisit these settings after any room layout changes or when adding new acoustic treatments.
Troubleshooting Common Issues
When the TCM‑XA does not appear on the network, confirm PoE power and that the LED shows green. If amber or red, inspect the Ethernet cable for damage or a loose connector. A faulty 802.3at injector can cause intermittent power; try a different port or injector.
Audio dropouts usually result from incorrect gain. Use Tesira to verify each beam zone’s gain is within the recommended range and that the overall level stays below the limiter threshold. If the mic is muted, ensure the mute switch is off.
Beam‑tracking problems, such as a zone that does not follow a speaker, often stem from a mis‑aligned microphone or an obstruction. Check the mounting bracket for proper orientation and secure attachment to the ceiling grid or plenum. Re‑calibrate the zones in Tesira if the room layout changes.
Firmware mismatches can produce communication errors. Verify that the TCM‑XA firmware matches the Tesira platform’s supported version. If not, download the latest firmware from Biamp’s support site and update via the web interface.
Persistent issues should be checked in the device log via Tesira diagnostics. Look for error codes like “0x01” (power failure) or “0x0A” (timeout). These codes help pinpoint the problem and determine if a replacement under warranty is needed.
If the device shows a blinking orange LED, it indicates a PoE negotiation failure. Verify that the switch port is set for 802.3at and that the cable meets Cat5e or higher. Replace the cable if it is old or damaged, and ensure the switch’s power budget can support 30 W. Also, check for electromagnetic interference near power cables. right.
