High Voltage Audio - HVA-4K VCA Stereo Bus Compressor Released!

HVA-4K Stereo Bus Compressor

We are pleased to announce the release of the HVA-4K compressor.

The HVA-4K is the successor to our long since sold out 4000 G-Series Compressor. It is the culmination of 12 months of work in redesigning, rebuilding and optimizing this classic circuit from the ground up.

We took the best parts of our 4000 G-Series compressor and optimised these with performance and an enhanced feature set at the heart of the HVA-4K design.

New Features and Enhancements include: Blend Control (wet/dry mix for parallel compression), Additional Ratios, Improved Signal-to-Noise Ratio, Facelift, True Bypass, User Switchable Mains Voltage along with much more.
