Shadow Hills Dual Vandergraph

The Shadow Hills Dual Vandergraph is a high-end, 500 series stereo compressor designed for professionals in the audio engineering and music production fields. Renowned for its rich, vintage-style compression, the Dual Vandergraph brings the essence of Shadow Hills’ flagship mastering compressor to a more compact, rack-mounted unit. This compressor is designed to provide precise control over dynamics while adding a unique tonal character to your mixes, making it ideal for both tracking and mastering applications.

One of the standout features of the Dual Vandergraph is its dual-channel design, allowing for stereo linking or dual mono operation. This flexibility ensures that it can be seamlessly integrated into a variety of studio setups. The unit features two compression modes: Discrete and Optograph, each offering a distinct sound signature, from clean and transparent to warm and colored. With its intuitive interface, complete with large, easy-to-read VU meters and solid, tactile controls, the Dual Vandergraph not only excels in performance but also enhances the overall user experience. This piece of gear is perfect for those seeking to add a touch of analog warmth and dynamic control to their audio projects.
