Metric Halo LIO-8 - Line Level Digital Audio Interface

LIO-8 - Line Level Digital Audio Interface, Metric Halo

The best of everything you need, without the stuff you don't!

When we introduced the ULN-8, people raved about the sonic quality, the features, and the power of our architecture. We also heard from the people that have their own "go to" mic pres, people that use analog consoles, and those that edit but don't record. They love the ULN-8 too, but didn't need the mic pres.

We heard you. For you, we have the LIO-8.

The LIO-8 incorporates the same Metric Halo Audio technologies in the ULN-8 including:

  • 192k sample rate support for both Analog and AES Inputs and Outputs
  • New DC-coupled, zero phase distortion, servo balanced Line Inputs and Outputs
  • Fully clickless remote controlled Monitor outputs. All LIO-8 analog outputs incorporate Metric Halo clickless remote technology allowing for flexible monitoring applications from stereo to 7.1 surround.


As with all Metric Halo products, the LIO-8 features an upgrade path. Or two.

While the base configuration of the LIO-8 doesn't include mic pres, you can opt to have 4 or 8 channels of the same ULN-R mic pres as the ULN-8 included in your unit. The LIO can be ordered this way from the factory, or the pres can be installed later.

You can also choose to upgrade your processing by adding the +DSP license, which adds over 100 plug-ins to your LIO and gives you the ability to create and save complex processing "graphs" as well as access to factory supplied "macros" including processors, amp simulators and more. Adding +DSP to your LIO is easy, just put the software license code into MIO Console and your box is unlocked.

Suite Solution

With everything you need to record, mix, process, and master audio (just add your DAW of choice, analog front end and transducers), the LIO-8 is your one-stop solution for recording, edit, mix and mastering suites. Even if you are using a DAW or recording system that does not support the LIO-8 Firewire interface, the unit's standalone operation and standard AES and analog interface allow you to use it as the Audio Front End and Monitor Controller for Pro Tools, standalone and PC based recording systems.

The Ultimate Digital Upgrade

The LIO-8 is a great way to upgrade your audio system. Put it between your existing gear and your DAW to get all of the benefits of our analog design, conversion technology and DSP without ripping your room apart. Adding a LIO to an analog console is like buying new converters and getting a digital mixer with total recall for free. Using our ConsoleConnect technology you can insert EQs, compressors, gates, reverbs and more into our v.5 Mixer and have all your routing and settings recalled with your DAW session.
