INTRODUCTION
TABLE OF CONTENTS
Thank you for choosing the Baby R.A.M. 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.

BABY RAM
DESCRIPTION
Heritage Audio’s Baby RAM is the ultimate passive-monitoring system, delivering the most transparent signal with the
best stereo imaging of any other passive designs available!
!
The Baby RAM is a boutique, passive-circuit monitor controller inspired by classic European console designs. A Baby
RAM is the ultimate controller for total transparency — a zero-compromise signal path, paired with a simplified control
set ensures your monitors receive the cleanest, purest signal possible without unnecessary complications.
The Baby RAM proudly features a 4 gang, 24 step rotary switch for volume as opposed to cheaper stereo
potentiometers, which means the precision of your stereo signal is perfect on every position as well as offering a sub-
tenth of a dB precision on every single attenuation position! Baby RAM also has no insertion loss, meaning that there’s
no extra coloration, signal loss or degradation at any settings.
!
Even though the Baby RAM packs a zero-compromise circuit design, it couldn’t be any easier to use with 2 pairs of
stereo inputs and outputs — both balanced and ground free (unbalanced compatible) on gold plated TRS jacks. Mute,
Dim, Mono, and Volume monitoring controls make the Baby RAM a breeze to work with. And with it’s passive design, it
also means you have no concerns with bad power supplies, as no electrical current is needed!
The Baby RAM is built with the most cutting edge methods in manufacturing and design, without ever compromising
audio quality or cutting corners — all at the Heritage headquarters in Madrid, Spain.

TROUBLE SHOOTING
PROBLEMS
SOLUTIONS
There is no sound coming from my Baby RAM.
Make sure the ´MUTE´ button is not pressed.
The audio from my Baby RAM seems less open than the
audio directly from my DAW.
Double check that you have not accidentally pressed the
´MONO´ button.
Even with the volume knob all the way up it doesn´t seem
to output as much as before.
You may have the ´DIM´ button pushed, reducing the
output by -20 dB.
There is no signal present at the Baby RAM´s Output.
Verify that you have correctly connected the Input and
Output cables.
There seems to be lots of extra noise coming from the
unit.
Try pressing the white ´Unbal´ button on the rear panel.
Is it possible to have both outputs or both inputs active at
the same time?
No, you can only use one Input and one Output at any
given time.
