Biamp Tesira Conferencing Audio Expander – EX-OUT

The Biamp Tesira EX-OUT (model code 920-00309-00001) is a half-rack conferencing audio expander with four balanced microphone or line-level outputs, powered by PoE+. It adds output channels to a Tesira conferencing system, with a -100 to +12 dB fader range and 24-bit converters. Procure.ae, an authorised reseller, supplies the Biamp Tesira EX-OUT across the UAE.

The EX-OUT provides four channels of balanced microphone or line-level output. A selectable full-scale output reference level (24, 18, 12, 6, 0 or -31 dBu) lets installers match the unit to connected equipment. The fader range is -100 to +12 dB, and signal invert corrects reverse polarity. The 24-bit A/D and D/A converters give a maximum output of +24 dBu, a frequency response of +0/-0.25 dB from 20 Hz to 20 kHz, and a dynamic range above 108 dB. Audio and control networking runs over AVB/TSN.

The EX-OUT is a half-rack chassis that fits a standard equipment rack alongside other Tesira hardware. It is powered by PoE+ (IEEE 802.3at Class 4, 30 W) and carries audio and control over AVB/TSN. Unlike the Tesira EX-USB and EX-UBT, which add USB or Bluetooth connectivity, the EX-OUT adds analog mic or line outputs. Procure.ae supplies the EX-OUT across the UAE, with free training and support.
