Heritage Audio TUBESESSOR optical tube compression

TUBESESSOR, the optical tube compressor for when you absolutely need
the sweetest, warmest most natural dynamic control possible, but also want
the ability to spice it up on occasion.

Always excited to see just how they can improve on and expand the functions of a classic,
Heritage Audio has decided to produce an optical tube compressor. It is well know that tube
compression, especially that based on an optical design, is generally considered to be warmer
than VCA and FET designs, and it tends to provide a very pleasant, more natural, smoother
result. This has made it the preferred choice for seasoned engineers and producers that want to
provide a very transparent control over a signal while offering a hint of enhancement but
keeping true to the original tone. For this very reason optical tube compressors are usually the
first thing one reaches for when dealing with critical vocals and bass signals. The
TUBESESSOR is the perfect option for this.
Analog excellence is achieved by combining an all tube-based amplification stage with an
outstanding UTC A10 input transformer replica by AMI, as well as a custom all-silicon steel
output transformer. With an elevated internal operating voltage you can be sure the
TUBESESSOR will heat up any signal while also maintaining its character and vibe. No starved
plate circuits here! Never has dynamics control been so easily obtainable while at the same
time so invisible. Even with generous amounts of gain reduction being applied anything
processed with the TUBESESSOR still maintains its clarity and depth.
Thanks to the TUBESESSOR ́S three unit high front panel you ́ll find plenty of room to adjust
the large Herchild-style knobs making it a breeze to achieve the desired sound. No cramped
spaces here, just plenty of space to easily and quickly adjust the settings to taste. The only bad
thing about this is that you ́ll dread returning to a confined one space unit much less a tiny 500
series module. In this case, size does matter…
Now, we all know it would not be a Heritage Audio product without our expertise and passion
channeled into a couple key features that take the TUBESESSOR to another dimension.
First of all, for those times when a bit more texture and bite is called for, there ́s nothing better
than a little saturation…or maybe a lot. The innovative TUBE SATURATION section takes full
advantage of a creamy sounding NOS Raytheon double triode tube to add in just a pinch of
aggression or fully transform the signal into something ready for war. It, importantly, works in
tandem with the custom output transformer to produce the right harmonic content. There are 4
available settings that vary from CLASSIC, no saturation, all the way to HOT, a heavily treated

signal. This feature alone opens up a ton of possibilities for drums and other instruments vastly

expanding the TUBESESSOR ́S uses. And thanks to Heritage Audio ́s use of an audiophile-
grade Psvane dual output triode in a totem pole configuration, a solid output stage is

guaranteed all while allowing much higher headroom than other tube compressors, whether
vintage or modern.
Secondly, there are also five internal sidechain filter settings to choose from. This is the exact
same filter section that helped the SUCCESSOR obtain its legendary status. Two of the options
make sure the compressor is not being unfairly overpowered by lower frequencies and the other
three are frequency specific options for extra creativity.
Continuously adjustable ATTACK & RELEASE controls in addition to a FIXED mode and a
combination of the two will provide all the necessary settings possible, allowing you to mold your
signal exactly as you ́d like. A huge, attractive custom VU meter for monitoring either Input,
Output or Gain Reduction guarantees you ́ll always be informed with a clear reading of exactly
what is happening. Everything you could possibly require to achieve a top-notch professional
recording.
As is the case with other tube offerings from Heritage Audio, the company has sourced NOS
tubes for a lifetime, making sure your investment is safe and sound.
