Vissonic VIS-VL1700A: Digital infrared transmitter
Model VIS-VL1700A
Overview
Central infrared transmitter that receives multiple audio signals in different languages and modulates them onto digital IR carriers for wireless distribution throughout the room.
Works alongside ceiling/wall IR radiators and personal receivers to deliver simultaneous interpretation to attendees.
Its rack-mount design allows easy integration into the AV rack alongside audio processors and digital conference systems.
Technical specifications
Equivalent Series
Based on the performance of the VIS-VLI700A series (4/8/16 digital IR channels).
Standards
Complies with IEC 61603-7 (IR audio systems) and IEC 60914 (conference systems).
Audio Channels
Typical configurations of 4, 8, or 16 digital channels (depending on the specific version assigned to VL1700A in the project).
Audio Inputs
Balanced XLR and/or RCA audio inputs from the interpretation console or conference system.
Carrier Frequency
Digitally modulated infrared band for high immunity to lighting noise and channel stability.
Outputs To Radiators
Connection via BNC or RJ45 type ports (depending on implementation) to the IR radiators distributed around the room.
Indicators
Display/LEDs for channel status, signal level, and IR transmission status.
Mounting
Metal chassis for 19" rack mounting in the technical room or interpretation booth.
Applications
Conference rooms, parliaments, auditoriums, and convention centres requiring multi-language infrared distribution.
Key features
- Digital architecture for improved signal-to-noise ratio and immunity to ambient light interference.
- Channel compatibility and performance aligned with the VIS-VLI700A series, facilitating use with VIS-VLI703A digital receivers.
- Professional audio inputs and dedicated connectivity to radiators, simplifying interpretation system design.
- Compliance with international standards for conference systems and infrared audio, suitable for institutional installations.
