ULN-8 – The Ultimate Solution
Building upon the experience gained with the Mobile I/O 2882 and ULN-2,
Metric Halo set out to design an integrated product to literally provide the
best performance in each of its component sections while still providing
all of the benets of tight integration in a single eld-capable package. The
ULN-8 is the result of that development program.
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 signicant benets 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.
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, editing, mixing 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 provides mastering room, archival quality conversion at
multichannel prices. From a quality perspective, the ULN-8 provides
a complete mastering toolkit - ready to drive a mastering suite. With
transparent converters (A/D/A conversion is inaudible) and transparent
reciprocal processing, the ULN-8 provides a load-in, monitoring and
processing interface for any mastering suite. Eight channels of conversion
and AES interfacing allow for multiple analog and digital processing signal
chains as well as monitoring and processing in surround. If more analog processing chains are required, additional ULN-8s may be added to a system.
• 8 Channels of mic pres with 91.5 dB of gain
• 8 Channels of Archival Grade 192k A/D converters
• 8 Channels of Archival Grade 192k D/A converters
• 2 Channels of Archival Grade 192k D/A converters with integrated
headphone amp
• 2 analog outputs on balanced TRS connectors
• Analog Balanced Send architecture for onboard split
• 2 Channels of Exceptional DI inputs suitable for instrument or
turntable inputs
• Integrated Surround Monitor Controller
• 8 Channels of 192k capable AES Inputs and Outputs
• Comprehensive Front Panel Controls
• Comprehensive, High Resolution 15 Segment Front Panel Metering
• Comprehensive Clocking (Internal, WC, AES)
• Dedicated internal clock sources for all rates
• Dedicated MIDI I/O for Control Surface interfacing
• Dedicated SMPTE LTC I/O
• Rock-solid, time-tested fth-generation software and drivers
• +DSP license included
The same quality standards apply to the preamps provided for the ULN-8. For recording, the ULN-8 allows you to leave the boutique preamps at home because
the preamps in the ULN-8 are boutique pres. They just don’t require extra power, weight or cabling to be used. Multiple ULN-8s may be combined to build largescale recording packages in a small space. The ULN-8 can also be combined with 2882 and ULN-2 units in a complete recording system.
The integrated mixer in the ULN-8 is not a mere cue mixer. It is a complete digital console with mono to 7.1 bus support, monitor control section, instantiable
delay-compensated processing with full delay-compensated send and return support in the mixer. Not only can you mix monitor mixes for performers with
essentially zero latency, you can also mix the show live for an immediate stereo reference.
At mix down time, utilize the acclaimed mixing and processing engine in the ULN-8 as your ultra-high-quality digital outboard summing system. Or, if you are an
analog-summing acionado, you can use the exceptional converters in the ULN-8 to drive your analog summing bus and capture the results. The ULN-8 A/D/A
is penalty free. But as many engineers have discovered, the exceptional mix-bus quality of the 2d Mix engine coupled with MH’s exclusive Character processing
may leave you wondering why you would go to the trouble to use an analog summing bus, as it is already in the ULN-8.
