Parlé TCM-1EX

What the Parlé TCM-1EX adds to a Biamp ceiling system

The Parlé TCM-1EX is a white pendant microphone built to extend a Biamp Parlé conferencing setup, not to replace it. It works as a second or third ceiling pickup point alongside a TCM-1 or TCM-1A, which must be present in every room that uses it. Rooms with long tables or several seating zones are where an added pickup point makes the biggest difference.

Beamtracking coverage and audio performance

Each microphone uses an 8-element digital array with a beamformed polar pattern. Beamtracking splits pickup into three 120-degree zones, covering the full 360 degrees of the room and tracking and mixing conversations within each zone. The figures published for this model are a sensitivity above 70 dB (94 dB SPL, 1 kHz), a frequency response of 150 Hz to 16 kHz within ±3 dB, a 92 dB A-weighted dynamic range and a 106 dB SPL at 0.5% THD. A green/red LED on the microphone shows mute status.

Daisy-chain layout and plenum box connections

The plenum box is the part that sits above the ceiling, measuring 51 mm high, 102 mm wide and 133 mm deep, and weighing 0.4 kg. It has two RJ-45 connectors: one links to the TCM-1 or TCM-1A, and the other to the next plenum box. A 2-pin 3.5 mm Phoenix connector feeds the microphone through a 3-metre (10 ft) cable. Plenum boxes can sit up to 10 metres (33 ft) apart, and a single daisy chain takes no more than three microphones in total: one primary and two TCM-1EX units. A green link LED on the plenum box confirms the connection.

Where it fits in Qatar

• Executive boardroom in West Bay or Lusail: a long table where the primary microphone covers one end and this expansion unit covers the far seats.
• Lecture or training room in Education City: a wide room with enough ceiling space for two expansion units on the far side of the audience.
• Government meeting room in Doha: a multi-purpose room that links local staff with colleagues abroad by video, where speakers should be heard clearly without microphones on the table.

What to plan before ordering

Check that the ceiling void has room for the plenum box and the cable route to the next unit in the chain. The source data does not give an operating temperature range for this model, so confirm conditions with the SmartRooms Qatar team before specifying it in a space that gets hot, such as a room beside a glazed façade or an unventilated void, where Doha summer temperatures can exceed 45°C. The power arrangement is listed as custom/proprietary, so confirm it against the full system design. Air handling suitability is evaluated to UL 2043, so state the ceiling type during planning. A free site survey from SmartRooms Qatar can cover routing and access before ceiling work starts.

The white model is covered by a 5-year manufacturer warranty. If you need to extend an existing TCM-1 room or design a new three-microphone chain, request a quote from SmartRooms Qatar and include the item number 920-00487-20000 with your room dimensions and seat count.
