Metric Halo recognizes that sometimes you already have mic pres you love or don't need pres at all, but you're eager to tap into the phenomenal conversion that's built MH's stellar reputation. They heard and delivered. Meet the Metric Halo LIO-8 FireWire Mac interface and standalone converter, borrowing its converter design from the acclaimed ULN-8 to deliver eight channels of straightforward archival-quality 24-bit/192kHz conversion whenever you need it.

  • Plenty of I/O with fully clickless remote-controlled monitor outputs
  • Offers pristine and colorless 24-bit/192kHz
  • Comes loaded with renowned DSP sound-shaping tools
  • Operates standalone when you need it
  • Expandable to work in tandem with other MH gear
  • Relevant today and tomorrow thanks to upgradability

Plenty of I/O with fully clickless remote-controlled monitor outputs
The hallmark of any Metric Halo piece of gear is a functional design with pro needs at the forefront. The connectivity of the LIO-8 matches that of the ULN-8, just without the eight preamps. (Keep in mind that if you decide you want to tap into Metric Halo's boutique-quality pres, you can upgrade your LIO-8 to add four or eight pres at any time with a connector board available here at Vintage King.) The LIO-8 offers eight line inputs plut eight channels of AES I/O with eight balances sends and eight line/monitor outputs plus MIDI and word clock connectivity. All of the LIO-8's analog outputs also feature Metric Halo's clickless remote technology, allowing for flexible monitoring applications from stereo up to 7.1 sound.

Offers pristine and colorless 24-bit/192kHz
Rather than lock you into a color from the beginning, the Metric Halo LIO-8 is designed for transparent performance built with a straight wire gain mentality. Metric Halo's goal was to provide the cleanest and most transparent conversion platform. If you want to put your very character-heavy mic pres in front of it or plug-ins after it to get color, you can dirty it up however you like, but the LIO-8 will ultimately give you what you give it. It's become a popular choice with mastering engineers for that reason.

Comes loaded with renowned DSP sound-shaping tools
Metric Halo was the first to make portable interface DSP a reality and the LIO-8 carries the tradition nicely. Thanks to its 2d DSP chip, you can take advantage of a bunch of included processing solutions, including Metric Halo's exclusive per-channel Character control that lets you dial in the right flavor and add some color to your inputs. You can also upgrade and get the +DSP license to tap into 100+ additional processing tools from Metric Halo's renowned collection.

Operates standalone when you need it
When what you need is an excellent standalone converter, the LIO-8 is your ticket. Just boot it in standalone mode and you'll be ready to go. The range of I/O onboard the ULN-8 opens up your options, with line inputs, eight channels of balanced send, eight line/monitor outputs, and eight channels of AES I/O, letting you go from and into just about anything.

Expandable to work in tandem with other MH gear

When you need a larger-scale setup, the LIO-8 is ready for expansion. It works seamlessly with other ULN-8, ULN-2, and 2882 units even scaling the DSP organically so you don't have to compromise.

Relevant today and tomorrow thanks to upgradability
Metric Halo is committed to making their new and legacy gear upgradable. After all, why obsolete your own gear? Their track record is proven, with even their earliest-era gear still in use today. To achieve the "future proof" design, Metric Helo's DSP processing card is upgradable and they're constantly making sure the MIO control software and drivers backing the unit up are as good as can be too. Plus, here, you can add microphone preamps to your LIO-8 at any time should your needs change, rather than go out and grab the ULN-8. The bottom line is that Metric Halo is all about protecting your investment and making sure you have an interface that sets a standard today and tomorrow too.
