Univox IR 1411 2-channel infrared transmitter

General Description

The Univox IR1411 is a compact yet powerful infrared transmitter for small to medium size venues. The transmitter features an integrated modulator with microphone level and line level inputs. 

The IR1411 provides wireless assistive listening with high audio quality. With two mono channels or single channel stereo operation on 2.3 and 2.8 MHz carrier frequencies, the unit is ideal for applications where information security and overspill control are of importance.

High performance IR diodes provide up to 730 sq/m in single channel operation. The system coverage can be increased with IR 1211 expansion radiators/emitters.
