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)

to line level.
*Note: Far-end input will be received through the USB channel if active.
The following input settings for IN 1 and IN 2 are available through the SDK:
Mic level (280mV peak-to-peak)
Line level (4V peak-to-peak)
Additional 6dB boost
Optional 3V phantom power supply
Output to room speakers is through "OUT 1". Units are preset to line level.
Far-end output to system is through "OUT 2". Units are preset to line level.
*Note: Far-end output will be transmitted through the USB channel if active.
The following output settings for OUT 1 and OUT 2 are available through the SDK:
Mic level (200mV peak-to-peak)
Line level (2V peak-to-peak)
