■Optical Tube Compressor
Optical tube compressors are typically the professional choice for natural, transparent control while preserving all the character and emotion of critical signals like voice when recording.
Heritage Audio has released the TUBESESSOR, their interpretation of this time-honored classic.
Manufactured in the EU with premium components, custom input and output transformers, and NOS tubes operating at extremely high internal voltages, this unique design ensures unprecedented clarity, depth, and headroom.
The TUBESESSOR is the perfect optical tube compressor for those seeking sweet, warm, and natural dynamic control, while also adding the occasional spice.
Not only does it warm up your signal while maintaining complete dynamic control, it also packs a few tricks into its sleeve.

■Sound Quality Secrets
- Tube Saturation
The TUBE SATURATION section offers four settings, from CLASSIC (no saturation) to HOT (intense tone), allowing for distinctive sonic expression. This significantly expands the tonal options available, providing far more sonic flexibility than other optical tube compressors.

- Side Chain
The acclaimed side chain filter section is now included, expanding the controls by allowing you to choose from five internal side chain settings. Two settings are designed to prevent the compressor from being overly suppressed by low frequencies, while the remaining three offer frequency response-specific options for creative sonic possibilities.
Continuously adjustable ATTACK and RELEASE controls, combined with FIXED mode, allow you to shape the signal exactly how you want.

- VU Meter Section
A large, attractive custom VU meter for monitoring input, output, or gain reduction ensures you always have a clear picture of what's going on.
The TUBESESSOR has everything you need for top-notch professional recording.
