Metric Halo's ULN-8 incorporates a number of Metric Halo Audio technologies including:

  • 192k sample rate support for both Analog and AES Inputs and Outputs
  • DC-coupled, zero phase distortion, servo-balanced Line Inputs and Outputs
  • ULN-R next-generation remote-controlled preamp technology.  The Mic Pres in the ULN-8 build upon the audio performance pioneered by the ULN-2 preamp design with the additional benefit and technological innovation of full clickless remote control of the ULN Mic preamp.  This is accomplished with a sophisticated gain switching mechanism which incorporates Metric Halo "zero-cross" technology.
  • Fully-clickless remote-controlled Monitor outputs.  All ULN-8 analog outputs incorporate Metric Halo clickless remote technology allowing for flexible monitoring applications from stereo to 7.1 surround.

By implementing all the functions of a complete audio front end in a single package, the ULN-8 is able to provide unprecedented power and quality in a lightweight, low-power consumption, single RU hardware unit.  This integration provides significant benefits to the owner in the form of reduced cabling (lower cost, weight and less opportunity for failure), weight, power consumption, and cost, while at the same time providing unprecedented performance.

Rather than pay for duplicate case work, duplicate power supplies and redundant interconnects, you get a product where all the components are engineered to work together and everything you pay for is dedicated to providing functionality towards the execution of your task.

By tuning all the functional blocks of the system and removing external interconnects, the ULN-8 provides enhanced performance and reduced chance of failure from external influences.  Connectors and cables are all potential sources of failure and interference.  By eliminating preamp to converter and converter to interface cabling, these sources of cost and potential failure and interference are also eliminated. I nternal operating levels within the box are tuned for optimal performance.

With everything you need to record, mix, process, and master audio (just add your DAW of choice and transducers), the ULN-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 ULN-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 ULN-8 is built around Metric Halo's 2d DSP platform, giving you the power to run multiple mixers and plug-ins inside the box.  It also includes a full +DSP license, giving you the ability to create powerful mixing, sound design and master plug-ins.
