INTRODUCTION
TABLE OF CONTENTS
Thank you for choosing the 80 Series RACK 2. Heritage Audio is dedicated to bringing you ´the sound of yesterday for
tomorrow´. We specialize in capturing that unique, enticing sound that everybody has fallen in love with. For years
engineers, producers and musicians have been yearning for that classic vibe. Usually the only option is to search for
old, used original equipment that is almost always in a questionable state of operation. This brings with it a whole lot of
other issues, making the experience less than desirable. Not to mention the very high prices asked for this equipment,
which makes them virtually unobtainable for the great majority. Now it´s possible to obtain that same sound with a
brand new piece that will give you all the problem-free, heavy-duty use you´ll need for years of music making history.

RACK 2
AC POWER CORD EU & US

DESCRIPTION
Our Rack 2 is handmade in the EU employing the same exact ISEP mechanical components used in the Series 80
consoles with aluminium rails, guides, etc. This will ensure your original vintage modules, as well as any of the currently
made modules, will fit like a glove.
Every channel has its own output control to attenuate the signal before the output transformer as well as an illuminated
phantom switch to provide 48 V.
In addition, 2 discrete Class-A ultra high impedance JFET Direct Inputs have been implemented, allowing for direct
injection of hi impedance instruments. These take priority over the MIC inputs and are before the input transformers.
The Rack 2 is also ready for linking up to two 2264E (Legacy Product) compressors.
Back panel features Neutrik gold plated XLR connectors for MIC and LINE inputs, as well as LINE outputs.
External power is connected via a popular IEC type connector. It accepts voltage from 90V-240 V. A power cable is
included with the Rack 2.

TROUBLE SHOOTING
PROBLEMS
SOLUTIONS
There doesn´t seem to be any power feeding the RACK 2.
Make sure it has been connected to an outlet. Accepts
between 90 V-240 V.
I´m trying to use a condenser microphone but it doesn´t
seem to recognise it.
Make sure you have activated the 48 V button for the
corresponding channel.
I´m getting too much signal at my DAW.
Try reducing the OUTPUT with the red knob on the right.
I´d like to change the Impedance from 1200 to 300 Ωbut
don´t know how.
There is a switch on the back of the modules that will
allow this. You will have to remove the module first to
access it.
