Product Overview
The QSC CIML4-HP is a high-performance Q-SYS Type-II I/O card providing four channels of switchable microphone and line-level analog input with 48V phantom power for the Core 510i processor. It pairs high-quality preamplification and analog-to-digital conversion to deliver premium audio capture for installations where input fidelity matters — such as performance venues, broadcast, and high-end conferencing. The card accepts microphones, mixers, and line-level playback sources.
Product Description

The CIML4-HP is the high-performance counterpart to the standard CIML4 input card. Its upgraded preamps and A/D conversion stage provide lower noise and greater headroom for critical sources, making it the choice when input quality is a priority within a Q-SYS design. It installs in any Type-II slot of the Core 510i and can be combined with other Type-II cards, so a single chassis can mix high-performance inputs with standard inputs, outputs, and digital cards. For standard-grade four-channel input, see the QSC CIML4.
