Heritage Audio Tubesessor Optical Tube Compressor

Optical Tube Compressors have been the choice of seasoned engineers and producers for recording critical signals such as voice where it is essential to retain all the individual character and emotion while offering a natural, transparent control… Now, Heritage Audio has released its take on this venerable classic, the TUBESESSOR.

A unique design manufactured in the EU with top-of-the-line components, customs transformers at the input as well as output and NOS tubes operating at an extremely high internal voltage to ensure a clarity, depth and headroom previously unheard of.

Not only is the TUBESESSOR the perfect choice for warming up and slightly enhancing a signal subtly all while maintaining total dynamic control, but it also has a few tricks up its sleeve…
