I. Introduction
Congratulations on your purchase of the Addicted to Music Bettermaker Equalizer - all analog sound with
the exibility of digital control!
Welcome to the family! The hybrid audio equalizer now in your possession is the result of years of research
and development in emerging digital control technologies. The nal hand-built result is currently glowing happily
in your rack (Lucky you). The EQ502P brings the exibility, ease of use, and instant recall-ability of software
plugins to the realm of high delity analog processing like no other analog EQ on the market.
Company
Addicted to Music began in 2004 in Warsaw, Poland as a recording and mixing studio. Long before it was
a hardware company we were deeply involved in the international music and recording scene. This is not a
company run by scientists who crunch numbers all day, we are a company run by engineers who live, eat, and
breathe music (like you do). We know good sound, and know rst-hand what it takes on both sides of the glass to
capture the perfect take. We developed the EQ502P to go from the perfect take, and make it even better!
Unit
The Bettermaker EQ502P was designed to have the greatest exibility of any analog EQ, while still allowing
absolute recall and repeatability. We often found the strengths of software plug-ins wasn’t their sound, but the
ability to quickly audition different settings. This allowed us to make faster, better informed musical choices. The
ability to jump back and forth between (sometimes vastly different) settings allowed us to keep a clear vision of
the sonic goal in mind, while quickly making decisions on the best setting to use.
However, we recognized the sonic superiority of our analog gear compared to their digital counterparts. In
countless shoot-outs, the analog versions always won. Since we’re a company that cares about better sound over
processing speed, our engineers would take the extra time to use a full analog chain because it simply sounds
better. We developed the Bettermaker EQ502P to give us the speed of plugins, but the delity of analog.
In the traditional analog world the time spent in the act of having to set and reset knobs and buttons to audition
between settings often skewed our choices. More time was spent tweaking knobs trying to recover an earlier
setting than was spent listening. The limited resolution of the mechanical parts often meant only very coarse
adjustments were possible (previously only solvable by very expensive mechanical switches). A difcult situation
to say the least, but the greater delity, openness, and depth of the analog gear was always worth it to our ears.
Even after years of advancement in digital algorithms, the older analog versions always sounded better. With these
goals in mind, we strove to create a hybrid EQ that was the best of both worlds: A true analog EQ based on classic
designs, but with the repeatability, ne resolution, and consistency of digital plug-ins. Enter the inspiration for the
Bettermaker EQ502P!
Design History
The EQ502P is a natural evolution of its older brother the Bettermaker EQ232P with our quality P circuit. The
circuits of the P sections are identical in both models.
We began with the analog sections. Choosing modern components and design practices over older traditional
methods helped maintain the transient response and low noise-oor necessary for today’s recording practices. We
hand build every unit, and even hand-wind the coil for the P-Filter section. Wherever possible we choose over-
spec’ed components to ensure trouble free operation and a long product life. Where feasible we increased the gain
resolution and frequency range to ensure the greatest exibility no matter what source (from tracking to 2-bus and
mastering applications). Most importantly we listened rst, tested, and then listened again. We hope you enjoy
your Addicted to Music EQ502P. Now go make some music Better!
