QSC IT-42 Isolation Transformer Pack

Extend the reach and flexibility of your QSC CX 302 amplifier with the QSC IT-42 Isolation Transformer Pack. This pro accessory lets installers convert the amplifier into a versatile distributed-audio driver, supporting two 25/70/100V lines in stereo or parallel and a single 140/200V bridged mono line for long runs. Designed to mount directly to the back of the amplifier, it requires no additional rack space and reduces installation time.

The IT-42 improves system reliability by providing isolation that minimizes ground-loop hum and preserves intelligibility—critical for paging, security, and surveillance applications. With an input voltage range that accommodates 140–200V bridged operation, the transformer pack is ideal for high-voltage PA, intercoms, and monitoring setups in commercial, institutional, and safety-critical environments. Integrators benefit from straightforward compatibility with QSC CX 302 hardware and faster commissioning on multi-zone projects.

Choose the QSC IT-42 to enhance audio distribution, simplify deployment, and ensure clear, reliable audio for paging and security monitoring. Add it to your next installation to streamline distributed audio and surveillance-ready systems.
