HT-D1000 Digital Network Audio Processor is designed
specifically for video conferencing and web video conferencing with
professional echo cancellation system that can handle long-distance
meetings often encountered annoying echo problem, can provide excellent
sound quality to the participants : |
| |
 |
Avoid network duplex
call echo completely. |
|
Suppress echo conferencing process. |
|
With the most advanced voice signal
processing function. |
|
Can be applied to remote network
video conference system. |
|
USB interface can be connected to
the computer. |

HT-D1000 Conference Echo Canceller is audio echo cancellation
process control system for 20 kHz, the output of the PLL to
maintain a fixed phase relationship with a reference signal.
Support for full-duplex, charge amplifier, low pass filter,
VCO and output converter composed entirely avoid network duplex
call echo. Audio is designed to solve the problem in a large
conference room, the launch of the latest solutions. The system
includes a versatile audio mixer, microphones distribution,
voice integration and upgraded features all video, online
or telephone conferencing systems.
HT-D1000 remote conference audio processors,
computer USB interface built-in two echo cancellers, microphone,
and stereo mix output. Effectively reduce the network to achieve
the inherent noise suppression echo conferencing process can
be used to implement on-site meetings and conferences to achieve
the perfect distance.

HT-D1000
remote conference audio processor advantages: |
|
| |
|
Echo
cancellation function can cancel echo completely and allow
local speech sent of truly full-duplex at all the time. |
|
Automatic echo cancellation and
howling suppression. |
|
The unique
dynamic noise filters which can filter out the conference
room equipment automatically such as fan noise does not affect
the speaker's voice. Thereby it improves SNR in sound quality. |
|
Signal processing,
adaptive echo canceller, feedback suppressor, noise canceller,
and automatic gain controller can be applied to audio and
video web conferencing and remote conferencing systems. |
|
The power from
the computer's USB port. Without additional power supply and
it can get power from USB port. |
