Single Channel 16KHz Echo Canceling System
USER MANUAL
MT107E-HD Single Channel 16KHz Echo Canceling System
The MT107E-HD is a DSP based, single channel, echo cancellation system designed to remove noise
picked up by microphones in standard to complex audio conferencing environments. The MT107E-HD
utilizes your own microphone and loudspeakers to create a complete audio conferencing solution.
Phoenix Audio Technologies' proprietary full duplex, echo canceling, noise canceling, and AGC
algorithms prevent gating and the loss of critical information and provide 16KHz of clear HD audio.
FEATURES:
Analog output through a standard 3.5mm jack
Digital output through USB connection
Controllable input level and phantom power supply (via free SDK)
Both microphone and far-end inputs connect through standard 3.5 mm stereo audio jacks
Powered via USB (AC/DC converter with USB connector is available for purchase)
SPECIFICATIONS:
32KHz sampling frequency; 100Hz-16KHZ bandwidth
Two level of echo canceling aggressiveness and three echo canceling speeds (via free SDK)
Controllable tail length of up to 240 ms.
Three levels of noise reduction: 8dB (low), 14dB (Medium), and 20 dB (High) (via free SDK)
Residual noise is suppressed to room level to prevent pumping noise
Eight preset color filters for both the output and speaker signal
Low delay (10 ms)

MODIFYING SYSTEM PARAMETERS THROUGH SDK
Audio engineers and installers looking to adjust the parameters of the MT107E-HD will have
this ability through the SDK. The SDK is a free utility, compatible with Windows, available
to download on our website. The SDK enables the parameters of the MT107E-HD to be
controlled, modified, and stored onto the unit. The SDK communicates with the
MT107E-HD through a standard USB connection. Once the settings of the MT107E-HD have
been modified using the SDK, the user can save the new settings onto the device.
The modifiable parameters of the MT107E-HD are:
Input level (mic/line/6dB boost)
Phantom Power Supply (yes/no)
Output level (mic/line)
The SDK is available at: http://www.phnxaudio.com/support/downloads
