The Spectrum™ is our most powerful infrared classroom audio system for use in larger gathering areas up, or a room where you need more than four speakers.

It is the ultimate audio system for group presentation; whether in a classroom, boardroom, or conference area. Its two channel receiver allows the simultaneous use of two wireless infrared microphones. Our Sapphire pendant is ideal for hands free presentation while our IRH-35 handheld can be passed around the room for individual participation.

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.

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.

Plug-in charger for IRT-55/IRT-60 Sapphire microphones.
