Master Control Unit


The TS-D1000-MU Master control unit for TOA's Digital conference system is designed to be used by way of simple connections to its Chairman and Delegate units using CAT5e STP LAN cables. The Master control unit is also equipped with a recording function, PC control (*1), and one-touch connection confirmation capability. Up to 32 Chairman/Delegate units can be connected in a simple daisy chain configuration. However, for further expansion, up to 5 TS-D1000-SU Sub control units can be added to the system, making it possible to connect as many as 246 Chairman/Delegate units in one fully integrated conference system. The TS-D1000-MU is also equipped with FBS (Feedback Suppression), enabling effective control of acoustic feedback. In addition the unit employs an MP3 recorder that makes it possible to record all conference contents to either a connected USB memory drive or internal memory. With the use of an optional rack mounting bracket, it can be mounted in an EIA Standard equipment rack (4 unit size).
(*1) Relevant control software is supplied on a custom-made basis.
