The DEC 6104 expander board is designed for installation into the DMU 6100 main unit of the RCF FORUM 6000 conference system. It adds the ability to expand the system to support up to 180 DMS 6410 microphone consoles through six lines, four of which are routed via the DEC 6104. Additional units require the DPS 6202 power supply. For system control, it features both a USB port and an RS 485 port for long-distance PC connectivity up to 1.2 km. The board integrates an anti-feedback processor to reduce acoustic feedback caused by high volume levels or microphone proximity. It also includes the FSW 6000 software for configuration and system management.
