Q-SYS COL4 4-Channel Balanced Line Output Card for Core

The Q-SYS COL4 is a dedicated I/O expansion card designed for AV integrators and system engineers who need to extend the analog output capability of Q-SYS Core processors. With four balanced line-level analog outputs, the COL4 enables precise signal routing to amplifiers, zone processors, or external devices without introducing the noise or ground loop issues common to unbalanced alternatives. It is the right choice when a Core platform must drive additional analog destinations beyond its native I/O complement.

Primary applications include installed sound systems in houses of worship, corporate AV, higher education, and performing arts venues where distributed audio zones require dedicated line-level feeds. The card slots directly into compatible Q-SYS Core chassis, keeping signal paths inside the same managed ecosystem and eliminating external interface boxes that add rack space and potential failure points. For production teams integrating Q-SYS into broadcast or live touring infrastructure, the COL4 provides a clean, deterministic analog output path that stays synchronized with the Core's processing environment.
