The PD-IR features FrontRow's exclusive great-sounding (and labor-saving) stereo infrared speakers. Each IR speaker unit combines two woofers, one tweeter, an infrared sensor, and single cable — saving up to half the installation time.
Teachers need only turn on the mic to start teaching. The receiver automatically wakes up from its energy-saving sleep mode and goes to sleep when the mic is turned off. The built-in sensor with advanced optics ensures consistent signal pick-up, so teachers can talk without dropout. FrontRow's powerful Adapto™ digital feedback suppression is automatically keeping harsh squeal at bay – before it starts. And OptiVoice™, FrontRow’s patented speech clarity technology, is on board to emphasize critical speech sounds, so kids comprehend even more.
