An Accessory Designed to Integrate the Unity U700 Elite into a Professional Rig
The Blackstar Unity U700 Elite is a bass head designed for demanding environments where reliability and quick setup are as important as sound quality. The Unity U700H adapter fits this "tour + studio" logic: it transforms a compact head into a perfectly integrated element within a standard rack, for a more coherent and easier-to-transport configuration.
Who and When to Use the U700H Rack Adapter?
The U700H is intended for bassists who want a stable, ready-to-play setup that is easy to cable. On tour, it helps protect the gear and save time during setup and teardown. In the studio, it allows centralizing the head in a rack with other devices to keep a tidy workspace and a clear signal path. If you already use rack-format equipment, this is the most logical solution to integrate the U700 Elite without any DIY modifications.
A Clean 19-Inch Mount Without Sacrificing Rack Space
The main advantage of the Blackstar Unity U700H is making the U700 head compatible with a 19-inch rack while maintaining a controlled footprint. Once mounted, the head uses only 2U, leaving room to complete your system with essential modules: rack tuner, multi-effects, dynamics processor, or power conditioner.
A Clearer, Faster, Safer Rig
In a rack, your configuration becomes more homogeneous: connections stay in place, transport is safer, and the whole setup is better protected in a flight case or rack case. The result: fewer logistical constraints, more peace of mind, and a setup tailored for rehearsals, sessions, and gigs both in clubs and festivals.
Note: Adapter Only
The U700H is supplied as a rack adapter only : the Unity U700 Elite bass head and the rack are not included.
