The TeachLogic IRT-60N delivers clear wireless audio with infrared transmission, featuring dual frequencies, cardioid pickup, and up to 8 hours of battery life for professional use.
The TeachLogic IRT-60N Sapphire is a wireless microphone system utilizing infrared transmission technology for reliable and interference-free audio delivery. It operates on two transmission frequencies, 2.08 MHz and 2.54 MHz, supported by six transmitting diodes that provide a 180° conical transmission angle. This ensures consistent coverage within an operating range of up to 60 feet (18.3 meters). Equipped with a cardioid microphone polar pattern, the IRT-60N effectively isolates the speaker’s voice while minimizing background noise.
The microphone gain can be adjusted across three settings: Normal, -3 dB, and -6 dB, allowing for tailored sound capture. The system employs FM wideband modulation with a pilot tone frequency of 32.768 kHz to maintain signal integrity. Powered by an internal 3.7 V, 620 mAh lithium-ion battery, the microphone supports up to 8 hours of continuous operation and recharges via a 5 VDC micro-USB connection. Compact and lightweight at just 3.5 x 1.3 x 0.8 inches and 1.4 ounces including battery, the IRT-60N is designed for professional environments requiring discreet and dependable wireless audio solutions.
