Description 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. Features Supports up to 180 DMS 6410 microphone consoles (via 6 lines)Includes 4 additional line outputs on the DEC 6104 boardRequires DPS 6202 power unit for powering additional 120 consolesUSB port for PC connection and system controlRS 485 port for long-distance PC control (up to 1.2 km)Integrated anti-feedback processorPLAY input for audio playbackIncludes FORUM 6000 control software (FSW 6000)Installed directly into DMU 6100 central unit Specifications Max Number of Consoles120Number of Console Buses4Communication BusSerialTotal Number of Inputs5Balanced Inputs4Unbalanced Inputs1Mono Inputs5Line Inputs1Line ConnectorsRCAPaging Inputs4Paging ConnectorsRJ45Signal Output Number1Signal Output ConnectorsRCADSP ProcessingYesConfigurationPC SoftwareDC PowerYesDC Power Value48 VSafety ComplianceCE compliantWeight0.82 kg / 1.81 lbsPackage Height100 mm / 3.94 inchesPackage Width300 mm / 11.81 inchesPackage Depth200 mm / 7.87 inchesPackage Weight1 kg / 2.2 lbs
