Contacta ID-7 – Compact and Efficient Hearing Loop Driver for Classrooms and Meeting Spaces

Contacta ID-7 is a compact, cost-effective constant current hearing loop driver designed to improve accessibility in smaller venues. With a 75V line input, it integrates easily with public address systems and offers high output voltage and current for driving larger loops.

Two ID-7 units can be connected to create a phased array system. The unit operates efficiently and remains cool without the need for external heatsinks. Its flexible mounting options and LED indicators make it ideal for both standalone and integrated installations.
