The CM1-6W and CM1-6WS hanging ceiling microphones provide a unique combination of coverage patterns, quality audio, pleasing aesthetics, and significant noise cancelling abilities when paired with the appropriate DSP algorithms.

Typically, audio quality is best when the talker is close to the mic, and the mic is further from the speaker, but it’s not always possible to install mics on a table. Whether it’s a matter of budget, logistics, or aesthetic preferences, ceiling mics are a viable solution for high quality audio pickup.

Manufactured by Audix, the CM1-6W and CM1-6WS are 6-inch miniaturized, gooseneck condenser microphones with fully integrated preamps designed with very high sensitivity for distance pickup. They are available with a cardioid or supercardioid capsule.

Where ceiling microphones were once viewed as a challenge to integrators, their quality and capabilities have improved, as have those of DSP algorithms, to effectively eliminate ceiling and HVAC noises as impediments to quality audio. Depending on the environment and combination of audio algorithms used, Biamp DSPs have the potential to exponentially enhance ceiling mic performance.

Audio systems should be flexible enough to accommodate multi-purpose spaces, room combining, and comply with the aesthetic requirements of the end user. In addition to providing solutions to those customer challenges, the CM1-6W and CM1-6WS ceiling microphones enable our integrator partners to purchase DSPs and microphones from a single vendor – allowing for a more complete audio solution from Biamp Systems.

    • Tesira Firmware v3.0.0.60
      **Please note that there is a known issue in the public release version 3.0.0 of Tesira Firmware.**

      The issue can cause Tesira expanders to occasionally become undiscoverable on the network, which causes a loss of audio to/from those expanders. This issue only affects Tesira systems that include Expanders and are set up in “separate” network mode, meaning that the Control network is completely isolated from the AVB network. It will not affect systems that are in “converged” network mode, which is the default (and more common) configuration.

      If your system meets this criteria or if you have questions regarding this issue, please contact the Biamp Technical Support Team at 1-877-BIAMP-XO for more information.
