1  Introduction 
Thank you for choosing Lynx Hilo for your audio needs. The device you have received has been precision engineered to provide the 
very best audio quality possible, coupled with an innovative, intuitive user interface, and a unique and powerful feature set. Hilo is one 
of the first pro audio devices on the market that utilizes a full-color LCD touchscreen for control, metering and configuration. Far 
from an unnecessary bit of “eye candy”, the touch display allows quick routing and setup, as well as a variety of accurate metering and 
measurement tools. New features will be available in the form of downloadable firmware updates, keeping Hilo responsive to your 
needs for many years to come. 
1.1  Overview 
Hilo represents the zenith of Analog conversion, improving on Lynx’s famous Aurora converters with state-of-the-art components and 
design techniques. The innovative design of the analog stage and converter topology allow ultra-low noise and distortion 
specifications, producing an unprecedented level of clarity and depth-of-image. Much more than a “me too” stereo converter, Hilo 
actually features three unique sets of analog outputs, each with their own Digital-to-Analog converters, and independent routing. Main 
Outs, Monitor Outs and Headphone Outs all can feature a unique combination of sources with independent level controls. 
1.2  Features 
Hilo also has an extremely generous set of Digital I/O options. Apart from AD/DA conversion tasks, Hilo is one of the most powerful 
digital format converters/routers on the market. Digital formats include stereo AES/EBU, Stereo S/PDIF Coaxial, Stereo Optical 
S/PDIF which is switchable to 8-channel ADAT lightpipe, and 16 channels of USB2 communication to a host computer. Any digital 
input can be routed to any analog or digital output, and all digital outputs can have unique combinations of source inputs. 
The unique 480 x 272 pixel LCD touch screen display makes Hilo stand out from other pro audio converters. Never before has 
establishing parameters and routing channels been so quick and intuitive in a high-end converter. Not only are clear and accurate 
meters provided, but the user can select from several meter styles. The Hilo display and features can be updated via simple computer 
firmware update tools, easily accessible from the Lynx website. Hilo’s feature set and display options will evolve in response to user 
feedback and the imagination of Lynx engineers. 
Hilo is also a game changer in terms of flexibility. It is well suited for recording studio use, the home recordist, mastering, audio 
analysis, home theater/audiophiles, as well as field recording. With AC or battery-powered DC operation, Hilo can be used “for here” 
or “to go”. With its lightweight, portable design, no longer does the discriminating user have to choose between top rung sound quality 
and convenience.
