- Forum 232 Amplifier/Receiver -
The Forum 232 is the perfect entry level Sound Field System for use in the classroom. The amplifier/receiver supports up to 2 infrared wireless microphones and multiple classroom audio sources all at once.
In addition to these must-have features, the Forum 232 includes a Digital Feedback Guard (DFG), computer anti-hum circuit, RS-232 input for a wall panel controller, lesson capture recording, and security alert compatibility.
- IRH-35 Handheld Microphone Transmitter -
For All Infrared Sound Systems
The handheld microphone/transmitter is primarily used by students for interactive class participation. The ergonomic design renders user comfort and very low handling noise. The unidirectional condenser microphone reproduces excellent vocal quality and the windscreen prevents breath pops. The emitting diodes are located around the top and bottom end of the handle for 360 Degree transmission and assured connectivity throughout the classroom.
- ICS-55 Infrared Dome Sensor -
The ceiling sensor is the preferred infrared sensor for optimum performance. It comes standard with Forum, Maxim III, Spectrum II, VoiceLink I, VoiceLink Plus, VoiceLink III and VoiceLink IV packages. This unit needs to be installed on the ceiling at least 3'-0" from the video projector. It comes with a mounting/support bracket and 50 feet of plenum rated cable with RCA connector on each end.
The ideal location for the dome sensor would be in the center of the ceiling. This will provide a clear signal path for the IR transmission from the transmitter to the dome sensor without obstruction. In addition, you will have 360 Degree coverage and will minimize the transmission distance for more reliable performance. It collects the infrared transmission signal via 6 large detecting diodes. The sensor is connected to the mixer/amplifier via a plenum rated cable terminated with RCA connectors. The mixer/amplifier supplies the power to the sensor.
- SP-628 Ceiling Speaker -
SP-628 is a 6.5" two-way full range compact coaxial ceiling speaker, providing low distortion and a smooth natural frequency response ideal for articulate vocal clarity. The SP-628 has integrated steel backcan along with 24" tile bridge which allows for quick and easy installation.ETL PLENUM RATED CONFORMS TO UL2043 STANDARD
