FEATURES

Handmade with ❤️ in Madrid
In order to guarantee the correct electron flux of the analog signal, we put together the finest “through hole” components, instead of robotically assembled miniaturized components. In this way we reduce to the minimum the electronic friction to enhance the thermal response of the equipment and avoid background noises.

Triad Magnetics® transformer
Every Gravity VCA Bus Compressor is equipped with an original Triad Magnetics® transformer to nurture the power stage, thus providing a more stable, precise, and lasting result, that does not generate any type of noise.

VU meters
Each Gravity VCA BusCompressor also contains one excellent VU meter so that you can accurately control the gain levels of the analog signal.

Gold plated connectors
When speaking about true ProAudio, all the links of the recording chain are fundamental. Gold plated connectors guarantee the best connectivity, and a total absence of contact noise as well. A real piece of jewelry in your hands.

Made of pure cherry wood
A picture is worth a thousand words. So, we wanted to ensure that you will know that your  Gravity VCA Bus Compressor has the makings of a champion only by looking at it. Finished with a warm and resistant natural cherry wood paneling, from sustainable forests, we ensure better thermal insulation and surprising aesthetics. Technology and art in a superb symbiosis.

Light and robust
By building our products in aluminum, we ensure the highest durability, lightness, corrosion resistance, and thermal insulation. Besides all this, aluminum is an easily recyclable metal that always retains its properties, avoiding indiscriminate exploitation. Makes sense, doesn’t it?

Cardboard packaging
The cardboard packaging in which we ship our equipment comes from recycled sources and is FSC certified. They are light and resistant, protecting the equipment from impacts during transport, thanks to the air chamber system that keeps the equipment in suspension. With this change, we use fewer raw materials and resources, and we can source locally. You can take it everywhere with you thanks to its handle, keep it to store your equipment, or recycle it.

Branded by fire
We want you to use your Gravity VCA Bus Compressor intensively for decades. That is the reason why the frontal and back panels are laser engraved, avoiding deletion or damage of the screen printing over metal or wood, through time.

Certified Authenticity and Quality
With your Gravity VCA Bus Compressor, you will get a Certificate of Authenticity and Quality, sealed and signed by hand, that contains the results of the technical measurements conducted over the equipment during our extensive quality control. Thoroughness, transparency, and a 5-years warranty.

One device, one tree
Not only do we create the best products, but we also care about the environment. Therefore, we commit ourselves to plant a tree in exchange for each sold device. You may visit it whenever you want!
