The TeachLogic Forum instructional audio system provides the classroom with a platform to clearly deliver all audio sources so that learning happens regardless of where the students are located. This versatile system supports 2 infrared wireless microphones, 3 classroom audio sources like a computer or TV, and 2 audio outputs for assistive listening system connection, lesson capture recording, and/or video conferencing to support hybrid learning models.

In addition to these must-have features, the internal architecture of the Forum™ includes a Digital Feedback Guard (DFG) to suppress unwanted noise, a Computer Anti-Hum Circuit to eliminate those pesky low level humming sounds computers can make, and a USB charger for convent placement of and access to the microphone charger.

A 4th audio source can be added by using the IRT-66 Mobile Display Transmitter. Now you can easily roll in a portable audiovisual cart to any classroom and instantly connect to the Forum’s speakers. No additional wires needed.

The TeachLogic SP-2000 is a full range 2-way compact wall mount/shelf mount speaker, providing low distortion and a smoother frequency response ideal for articulate vocal clarity for more even coverage. The included wall-mount bracket enables the unit to be secured against a wall or other flat surface.

The Sapphire is our flagship microphone designed specifically for educators. Hands free, lightweight, and hardly noticeable when worn on a lanyard or clipped directly to your neckline collar. It transmits wirelessly to a TeachLogic audio receiver, which can be part of a complete TeachLogic classroom audio system (microphone + amplifier/receiver + speakers) or added to an existing sound system by using our VoiceLink I receiver. Regardless, the Sapphire ensures your students hear equally well.

Performance: The Sapphire’s vocal clarity is unsurpassed. It boasts high level output, reliable connectivity and exceptional definition. With a built-in breath filter, the Sapphire can also function as a pass-around hand mic.

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° transmission and assured connectivity throughout the classroom.

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° 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.

• Drop in Charger for Handheld transmitter
