The QSC LLC C1 is a single-gang, IP-enabled wall controller designed for distributed audio systems operating on 70-volt architectures. It provides local volume control at the zone level, allowing installers to give end users a simple, wall-mounted interface without requiring access to the central amplifier or DSP. The C1 mounts in a standard single-gang electrical box, making it a practical fit for retrofit and new-construction commercial audio installs alike. AV integrators and low-voltage technicians are the primary trades that specify and install this device.
The C1 is suited for commercial and light-commercial environments where 70V distributed audio is the standard infrastructure — conference rooms, retail spaces, restaurants, houses of worship, and similar multi-zone applications. It provides local user control at individual zones while the central system retains master-level management. It ships as a single unit (sold individually).
Designed for use in 70V distributed audio systems; confirm compatibility with your specific QSC control system infrastructure before ordering, as no additional model-specific compatibility data was provided in the product listing.
Installation is typically performed by a licensed low-voltage technician or AV systems integrator. Power down or de-energize the relevant audio system circuits before wiring the controller. The device mounts in a standard single-gang US electrical box; follow local building codes and NEC low-voltage wiring requirements for in-wall cabling. Do not connect to high-voltage AC wiring circuits.
