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: 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.
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. The auxiliary input allows wireless playback of an audio device like a music player. A three-position slide switch provides selection of HIGH, MID or LOW (Normal, -3dB or -6dB) microphone volume level.
Safety: The IRT-60 features Security Alert, holding down the priority button for five seconds activates a security alert through the existing intercom system.
This is a suitable replacement for IRT-55 and IRT-89 infrared microphones.
