The eight on-board microphone preamps are of unusually high-quality for a portable device of this kind. The ULN-8 ships the v.5 mixer, a software mixing engine with "character" options on every channel. The character options are models of analog circuits, vintage tubes, FETs, transformers, etc. You can use the ULN-8 in stand alone mode if you just want to utilize its premium preamplifers, or for format conversion.

If you need more I/O and DSP power, you can link up to 3 ULN-8's together. It can also link with Metric Halo's other hardware interfaces, the ULN-2 and 2882. The purchase of a ULN-8 includes a full license to +DSP, Metric Halo's dedicated signal processing software. The front panel of the ULN-8 offers comprehensive metering, with 16 meters and a total of 495 bi-color LEDs.

The extensive digital and analog I/O on the back panel is carried out with DB-25 connectors with Tascam/Digidesign pinouts. The ULN-8 is compatible with OSX 10.3.9 or newer, and plays well with both Intel and PPC processors. For power users who understand the benefits that can be reaped in a quality piece of equipment, the ULN-8 is a well-rounded solution that offers uncompromising audio quality in a travel friendly package.
