Intelligent Audio Control for Professional Venues
The A-02 sets a new standard for mid-to-large-scale wireless audio. Equipped with a vibrant full-color display on the receiver, AV technicians can instantly monitor critical data including RF signal strength, audio levels, battery life, SQ distance, and channel locking status.
Designed for rapid deployment, it features one-click independent locking, IR infrared frequency matching, and digital pilot technology. This ensures that the receiver completely mutes the AF signal when the transmitter is turned off, effectively blocking out any rogue interference signals in open spaces up to 80 meters.
