ABOUT PULTEC

In 1951, Gene Shenk and Ollie Summerland of Pulse Techniques Inc. introduced the first passive
program equalizer, the
initial Pultecs suffered the gain insertion losses typical of passive filters. So, they added a gain makeup
stage, using a push-pull design with multiple vacuum tubes. The result is the classic we’ve come to know
as the EQP-1A.
Conceived and created for broadband equalization, the EQP-1A features four low boost/cut frequencies,
three high-cut frequencies and seven HF boost points, alon

1.3 About the Modeling
Many different elements contribute to the unique sonic chara
EQP-1A. Waves painstakingly modeled and incorporated these elements into the PuigTec EQP-1A in
order to fully capture and replicate the sound and performance of the original equipment.
These are some of the most important elements of analog behavior:
•
Total Harmonic Distortion
Perhaps the most important analog behavior is Total Harmonic Distortion or THD, which is
defined as t
fundamental frequency. THD is usually caused by amplification, and changes signal shape and
content by adding odd and even harmonics of the fundamental frequencies, which can change
the overall tonal balance. THD can also change peak output gain, usually by no more than
+/- 0.2-0.3 dB.
he ratio of the sum of the powers of all harmonic components to the power of the
• Transformers
Some hardware uses transformers to stabilize or change Input/Output loads and signal levels.
In earlier days, transformers did not have a flat frequency response, and often introduced low
and super-high frequency roll offs. The original Pultec EQP-1A has transformers which cause
high frequency roll off, so if you encounter loss above 10kHz, this is due to the modeled
transformers.
•
Hum
Waves modeled both 50Hz power current and 60Hz power current. If you listen closely, you will
hear that th
each region and dependent upon the local electrical conditions, you may find that the modeled
hum is different than the hum already present in your studio, and may not be suitable for your
particular use.
• Upon Instantiation
Upon instantiation of the PuigTec EQP-1A, you may hear a small change in frequency balance,
which sounds like top end boost, introducing about 1dB of gain. This replicates the actual
behavior of the modeled hardware, and will vary as you change the low cutoff frequency. This is
also an attribute of the original hardware, caused by the interaction of its filters.
