LIO-8 3d


he Metric Halo LIO-8 3d is a 24-bit / 192 kHz USB Type-C audio interface offering eight line-level inputs and insert sends, multichannel digital I/O, DSP-powered mixing, and software control for musicians, engineers, and producers in studios and mobile setups. Its integrated dual-core DSP powers a variety of plug-ins—the included DSP+ license unlocks over 100 of them—without burdening your computer's CPU. Robust software ensures easy access to multi-track recording, mixing, monitoring, and more.

The LIO-8 3d's high-resolution converters are fed by DB25 line inputs and two 1/4" Hi-Z DI inputs; all eight inputs feature up to 31.5 dB of gain, informative metering, and front-panel gain controls. Analog outputs include eight line outs via DB25, and a 1/4" headphone jack, which can be affected by the front-panel volume, mute, and dim functions. The LIO-8 3d also mirrors its line inputs to eight insert sends for efficiently splitting to a mixing console or summing bus.

Properly synchronize with other equipment through the BNC word clock jacks and 1/4" SMPTE I/O. The 5-pin DIN connectors allow hookup to a MIDI control surface. Consolidate audio, clock, and data I/O with other 3d-equipped Metric Halo interfaces via the RJ45 MH Link ports. The LIO-8 3d connects to a compatible Mac, Windows, iOS, or Linux device via the supplied USB Type-A to USB Type-C cable. Power it with the included power supply or via a 4-pin XLR power system (available separately).
