The LR-4200-IR-P1 offers four selectable IR channels with advanced DSP, delivering clear audio with low distortion and an OLED display for easy control and monitoring.
The Listen Technologies LR-4200-IR-P1 Intelligent DSP IR Receiver Package 1 is designed for precise infrared audio reception with enhanced digital signal processing. It supports four selectable carrier frequencies—2.3, 2.8, 3.3, and 3.8 MHz—ensuring stable performance with ±0.005% frequency accuracy. The receiver provides a frequency response range from 63 Hz to 15 kHz (±3 dB) and maintains total harmonic distortion below 2% at 80% deviation for clear, high-quality sound.
Equipped with two 3.5 mm unbalanced audio output jacks, the unit accepts mono or stereo plugs and delivers a nominal output level of 0 dBu with a maximum power of 16 mW at 32 Ohms impedance. User controls include power on/off and volume adjustment, with channel selection accessible through a press-and-hold button function. An OLED display presents channel designation, battery level, unit number, charging, and volume status for intuitive operation.
Powered by a lithium-ion battery, the receiver provides up to 8 hours of typical use and recharges fully in 2.5 hours via a 5 V micro-USB connection. Additional features include programmable IR squelch with 20 steps, automatic shutoff after 30 minutes without IR signal, and LED indicators for battery status. The compact, flat black unit measures 3.75 x 2 x 0.64 inches and weighs 1.9 ounces without batteries, suitable for various assistive listening applications.
