The ECS-Teleconference unit is an echo cancellation system (ESC) that is designed to produce clear audio for teleconferences, with no delays or doubletalk.
At the heart of the system is a digital signal processor using Dynamic Automatic Echo Cancellation, based on a wideband acoustic echo cancelling algorithm developed by Ateis' R&D department.
This technology enables the ECS to produce natural, full duplex speech with a bandwidth of 20Hz to 27kHz, which brings benefits during conversations involving large numbers of people.
The ECS range currently comprises eight units, which provide a range of tools for producing clear, successful teleconferences. The system features integrated compressor-limiters, equalisation, matrixes and delay capability, augmented by configurable routers and comprehensive signal processing.
This is all controlled from the ATEIS-NET graphical user interface, while additional components are available from the ECS DSP library to create larger, more fully functioned systems. These include Automatic Gain Control, Feedback Killers, Meters, Generators and Automatic Microphone Mixers.
Users are able to programme how audio signals are processed within the ECS to suit their personal preferences or the demands of the installation. The entire system can be configured using PC software and controlled using specific screens, RS232 or optional remote controllers. Multiple ECSs can be run over Ethernet, ATEIS netLink or ATEIS Fibre-NetLink.
ECS features up to 16 wideband AES software modules and a maximum of 24 configurable hardware units, which have electronically balanced inputs and outputs. Also included are a telephone interface, Ethernet port and a remote control bus.
"Teleconferencing is vital in these days of fast-paced international business but there is an even greater need for clear communications with no delays," comments Ateis' international sales manager, Albert van der Hout. "The new ECS gives excellent audio quality and allows users to program it to suit their needs. We see ECS as an important new tool for businesses around the world."
