Quam TCH70 10W Transformer

Deliver clear, reliable audio where it matters most. The Quam Speakers TCH70 10W Transformer is an open-frame, 70V audio transformer engineered for professional paging, security and surveillance installations that require low-loss performance and consistent voice reproduction. Rated at 10W with five -3dB selectable taps, the TCH70 lets integrators fine-tune power to individual speakers for even coverage and optimal intelligibility in monitoring rooms, access control booths, and public-address zones.

Its extended low-frequency response reduces muddiness and enhances speech clarity in noisy environments, while the compact 11.6" x 2" x 1.5" footprint and 7" color-coded leads simplify mounting and wiring in racks and enclosures. Built to perform in commercial audio distribution and security systems, this transformer supports reliable operation across paging, intercom, and surveillance audio channels.

Choose the Quam TCH70 when you need professional-grade, easy-to-install audio distribution for security, surveillance, and monitoring projects. Contact sales or add it to your specification sheet for your next installation.
