The SIR 320 receiver has been designed to receive a maximum of 32 channels within the standard frequency band. The use of a PLL-synthesizer guarantees high quality transmission and also high operation reliability.
The generation of this infrared receiver allows the use even under direct solar radiation where normally the reception would not be possible due to excessive brightness. The receiver is equipped with 4-button control pad for volume and channel control. Volume level and channel number are displayed on a back lighted LC-Display which also shows the system status or the system adjustments, i.e. the battery voltage, the IR field intensity and the shift operation mode. After removing the receiver out of the infrared field or after
disconnecting the headphone, the receiver switches automatically into the stand-by mode. In this way, it is also guaranteed that the receiver is working energy-saving. The ergonomic housing features an integrated fixing clip.
