VISSONIC VIS-VLI703A-16

Description

Digital 16 channel infrared receiver

Description

The portable infrared receivers can receive up to 32 different audio channels, have a channel selector switch, volume control, on/off switch and a 3.5 mm mini jack headphone jack.

Properties

The easy-to-read LCD display shows channel number, language, signal reception strength, battery level and listening volume. The infrared receivers are suitable for both voice and music transmission.

Compatible with other infrared transmission systems that transmit according to the IEC 61603-7 standard.
Fully digital DQPSK modulation and demodulation technology guarantees the highest sound quality with very good speech intelligibility.
The transmission of voice channels in the high frequency range prevents interference from other interference signals such as fluorescent tubes.
Up to 32 transmission channels simultaneously.
The receivers are easy to use.
The easy-to-read LCD display on the receiver shows the language being listened to, the channel number, the battery level, the reception strength and the volume of the voice channel.
The number of selectable channels always corresponds to the actual number of active channels available. This means there is no need to scroll through unused channels.
The listening volume is adjustable.
The very wide reception angle of 270º always guarantees good reception with very good sound quality.
The reception signal is automatically muted if the reception quality falls below a certain level. This reduces annoying noise or clicking in the headphones.
IEC 60914, IEC 61603-7 and GBT 15381-94 standards compliant.
