Improving on a ClassicThe objective behind the HVA-4K was simple: take a classic stereo bus compressor design and improve upon it.
Hand built in Australia, The HVA-4K is the next generation of our VCA Stereo Bus Compressor. It is the culmination of 12 months of work in redesigning, rebuilding and optimising 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.
We listened to engineer’s feedback and we implemented the most requested features in this design. The VCA based compression is renowned for its sonic "glue", providing transparent punch and cohesion to a mix without sacrificing clarity.
New Key Features and Enhancements
- BLEND Control: the blend control makes it quick and easy to apply parallel compression by adjusting the blend of dry and wet (compressed signal). This negates the need for any complex DAW based routing.
- Extended RATIO Controls: We've expanded upon the typical 3 ratios to 6, including the most frequently requested 1.5:1 ratio.
- IMPROVED Signal-to-Noise Ratio (SNR): the circuit redesign and optimisation means a noise floor of -105dB or better.
- FACELIFT: the feedback from engineers was that they preferred the aesthetics of our EQ6S equalizer. We ditched the collet knobs and enlarged the front panel scales giving the HVA-4k a similar appearance to its sibling.
- TRUE BYPASS: the bypass circuit was redesigned to provide a relay based bypass mechanism. This means the unit passes audio whilst powered off, and the bypass function skips the entire audio path.
- User SWITCHABLE Mains Voltage: rather than a hardwired mains voltage, the HVA-4K is user switchable between 115V/230V.
