This relay card for 8 loudspeaker lines is designed for professional PA and sound reinforcement systems where reliable switching of multiple speaker circuits is required. It allows precise control of speaker zones and is particularly suitable for emergency priority handling or flexible signal distribution in complex installations.

The card features eight durable relays with AgCdO (silver cadmium oxide) contacts, optimized for switching medium inductive loads up to 600 VA. This contact material ensures excellent conductivity, durability, and resistance to arcing during frequent switching.

A key feature is the ability to internally bridge the NO and NC relay contacts via jumpers, significantly reducing wiring complexity and installation time. This is particularly useful for fast configuration of multi-zone routing and emergency override paths.
