Introduction
Thank you for purchasing a Focusrite Module.
We had a lot of fun designing it; many people took a lot of care and pride in making it and we all
hope that you will enjoy owning and using it. We also trust that it will earn its keep, be reliable and
useful for a long time to come.
We do understand that reading the manual is almost always the last resort, however this User Guide
has some data about the module which you may be of help if all else does fail. This booklet also
describes the other modules in the Focusrite range which may be of interest. If you would like to
audition or try any of these other modules please contact your dealer or the factory.
Overview of the Range
All the modules in the Blue Range use the Focusrite circuits which exhibit the usual Focusrite
attributes and audio circuitry of the finest quality available with very wide bandwidth, low noise
and distortion and individually buffered stages.
The Blue modules tend towards a solid look and feel with cases made of aluminium and stainless
steel and usually include hand wiring of front and rear panel components. Several of the Blue range
modules are principally configured for Mastering and Broadcasting requirements.

compressor and limiter functions, PPM metering and a true stereo mode.
