The TeachLogic Sapphire is a hands-free, lightweight microphone that is hardly noticeable when worn on a lanyard or clipped directly to your neckline collar.
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.
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 contact closure.
