This package/System includes the following:

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.

Performance: Sapphire’s vocal clarity is unsurpassed. It boasts high-level output, reliable connectivity, and exceptional definition.

Function: Hold for 1 second to power ON. The “TL” light will glow blue. With a tap on the power button, the mic mutes (blinking blue light) for private conversation - tap again to restore to normal operation.

Safety: The IRT-60N features Security Alert, holding down the priority button for five seconds activates a security alert through the existing intercom system.

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 an RCA connector on each end. The ideal location for the dome sensor would be in the center of the ceiling.
