Product Overview
The QSC CIML4 is a Q-SYS Type-II I/O card that provides four channels of balanced mic/line analog audio input with 48V phantom power for the Core 510i processor. It accepts condenser and dynamic microphones, line-level sources, and balanced analog signals from any professional audio device, bringing them directly into Q-SYS signal routing. Because each Core 510i chassis takes up to eight Type-II cards in any combination, the CIML4 lets integrators build exactly the analog input count an installation requires.
Product Description

The CIML4 installs in any Type-II slot of the Core 510i and can be mixed freely with output and digital cards to match the room. Its 48V phantom power supports condenser microphones for conferencing and presentation, while the line-level capability handles playback devices, mixers, and other balanced sources. For analog outputs in the same chassis, pair it with the COL4 line output card. Integrators who need higher-grade preamps should consider the high-performance CIML4-HP variant.
