DSP Systems

ECS - Networkable Echo Cancellation System

ECS
Designed for conference applications requiring Acoustic Echo Cancellation, the ECS is also suited for many other audio installations requiring drag and drop software and a high powered DSP engine. The AEC component is not resident on the Input Card, but on a separate chip inside the box. Hardware system configurations are flexible with up to 24 I/O configurations in locks of 4. Up to 16 Echo Cancellation channels in blocks of 4, and an optional telephone card is also available.

Software system design is PC based via ATEIS Studio software residing on a PC. Once connected to the ECS, ATEIS Studio allows for design downloading, reversal of in-box designs, and live monitoring, calibration, an routing via the PC. Third Party control systems such as Crestron, AMX, Vity and others can also control the ECS either via RS232 or IP commands. Up to 128 ECS units can be networked with up to 4 miles between each unit (fiber connection). A variety of accessories, including low cost analogue controllers (RAC), digital controllers (URC), and various paging and control microphones (PPM, PPM Touch) are available for use with the system.

ECS
The Digital Audio Platform shall be available with up to 24 inputs and outputs. Inputs/outputs shall be specified in blocks of 4, up to a total of 24. Mic/line Input, Acoustic Echo Cancellation, Telephone Interface, and Mic/Line Ouput options shall be available. Inputs/outputs shall be analog, with internal 24-bit A/D & D/A converters operating at a sample rate of 48kHz or 96 kHz. All internal processing shall be digital (DSP). Electronically balanced inputs and outputs shall be provided on plug-in barrier-strip connectors. Inputs and outputs shall be individually programmable for either microphone or line level signal. Expansion modules for up to 128 ECS systems in a network shall be available. Each hardware configuration shall include 32 bit ADSP 21369 DSP. Software shall be provided for creating/connecting

Available system components shall include (but not be limited to) various forms of: mixers, equalizers, filters, crossovers, dynamics/gain controls, routers, delays, remote controls, meters, generators, and diagnostics. Ethernet communications shall be utilized for software control, configuration, and DSP distribution. Each multi-unit application shall feature a fully redundant network configuration with less than 0.02 ms latency between units. All network configurations shall be via CAT5 cable or fiber-optic. After initial programming, systems may be controlled using either TCP/IP or RS-232 serial communication by third party control systems (such as AMX® and Crestron®), by PC computer, and/or by dedicated remote control devices. Software shall operate on a PC computer, with network card installed, running Windows® XP Professional/Vista/Windows 7. The Digital Audio Platform shall be CE marked, UL/C-UL listed. Warranty shall be 5 years.
