Metric Halo LIO-8 mkIV — an 8-channel USB-C audio interface and 4th-generation A/D-D/A converter with a hybrid DSP/FPGA engine and a built-in monitor controller supporting up to 7.1.4 Dolby Atmos.
The LIO-8 mkIV is built on Metric Halo's 3d Core architecture, integrating directly with other Metric Halo units over MHLink into a single routing and processing system regardless of how many units are chained together. The unit provides 8 line inputs and 8 line outputs on DB-25 connectors, a 128-channel by 64-bus mixer, and resolution support up to 192 kHz, with the option to add up to 8 channels of ULN-R mic preamps in 4-channel blocks.
A Mobile Studio in One Rack Space
Field work — live concert tracking, remote sessions, production on the road — calls for gear that fits in one case and doesn't depend on mains power. The LIO-8 mkIV closes the entire signal chain into a single rack space, stays lightweight, and can run directly from DC power (16-30V), removing the need to carry a mains supply. USB-C class-compliant connectivity means it connects to Mac, iPhone, iPad, Windows 10+, or Linux without installing a driver, cutting setup time before a session down to almost nothing.A Monitor Controller Built Into the Converter
Immersive mix and mastering sessions usually call for a dedicated monitor controller as a separate rack unit. The LIO-8 mkIV integrates a full multi-source, multi-destination controller supporting up to 7.1.4 Dolby Atmos, analog gain control, and relay hard mutes directly inside the converter. DSP/FPGA processing runs at zero added latency, and a bundle of over 100 plug-ins lets an engineer build EQ, compression, and other processing into the monitor path without loading the host computer or introducing delay in the listening chain.KEY FEATURES
