The Metric Halo ULN-2 - FireWire Digital Audio Interface (with 2 Jensen Input Transformers + DSP) is a portable, FireWire based, multi-format studio recording audio converter and interface. Housed in a single space rack-mount chassis, the unit provides 12 inputs and 14 outputs of simultaneous I/O, while having the ability to be powered from the FireWire bus of a laptop computer, or from an appropriate DC power source. This version of the audio interface includes a modification wherein two Jensen input transformers have been added to the signal path to add low-order harmonic distortion which provides a depth and smoothness to the sound of your music. An additional benefit of the Jensen transformers is that they electronically isolate the preamplifier from the source which raises the common mode rejection of the device.
This version of the audio interface also includes the +DSP license which allows you to insert plugins such as multi-band EQs, compressors, limiters, distortion processors, guitar amp models, vintage reverbs, parallel processors, and more into the signal path within the v.5 software digital mixing console without taxing your host CPU.
The ULN-2 2d is equipped with 2 balanced analog inputs on Neutrik combo connectors, 2 channels of digital I/O (AES/EBU and S/PDIF) and 8 channels of ADAT lightpipe I/O. Two balanced analog outputs and 2 balanced monitor outputs are available for connecting directly to power amps or self powered monitors. Wordclock I/O and dual FireWire connectors, along with 24-bit, 96 kHz converters on all channels, make the ULN-2 suitable for high quality digital recording.
The interface can be used for capturing audio wherever inspiration hits, in the studio or on the road. The microphone preamps provide an ultra-fast slew rate, and the fully balanced analog inserts allow outboard analog dynamics processing to be introduced between the preamps and the A/D converters.
The On-board DSP powers the v.5 MIO Console, which can function as a mixer, router, and control application. The software can be used to route any input to any output, providing a range of flexible mixing possibilities. A "Record Panel" allows for straightforward recording of incoming audio without the need for additional DAW software. This is especially useful in situations where immediate editing is not required, but stable, fool-proof recording is essential.
