Optical tube compressors have been chosen by experienced engineers and producers for recording critical signals, such as vocals, where it is important to preserve the individual character and emotions while providing natural, transparent control. Heritage Audio has now released their take on this venerable classic, Tubesessor.
The unique European-made construction includes state-of-the-art components, special input and output transformers, and NOS tubes operating at extremely high internal voltages to provide clarity, depth, and power reserves previously unheard of. Tubesessor is not only an ideal choice for warming and slight signal enhancement while maintaining full dynamic control, but it also has a few tricks up its sleeve.
The Tube Saturation section allows you to add character with 4 settings ranging from Classic, without saturation at all, to Hot, an angry tone ready for battle. This significantly expands the tonal options you can achieve with Tubesessor, making it much more flexible than any other optical tube compressor.
Heritage Audio also decided to include their legendary sidechain filter section to further expand control with five internal sidechain settings to choose from. Two settings ensure that the compressor will not unfairly overload with lower frequencies, while the other three are frequency-dependent options for additional creativity.
Continuously adjustable Attack & Release controls in addition to the Fixed mode and their combination provide all the necessary settings to shape the signal exactly as you would like. A huge, attractive volume meter for monitoring input, output, or gain reduction ensures you are always in the know.
Everything you need to achieve top-notch professional recordings. Tubesessor, the optical tube compressor for when you need the sweetest, warmest, and most natural dynamic control, but also the ability to bring it to life from time to time. As with other tube offerings from Heritage Audio, the company sources NOS tubes for life, guaranteeing that your investments are safe and reliable.
