XSCACE ROOTS DSP

The legacy Windows DSP editor for Root-series amplifiers.

XSCACE ROOTS DSP is the original Windows editor for Root-series DSP amplifiers, covering 2-in/2-out and 4-in/4-out hardware over USB or the local network. It exposes the full signal chain: a routing matrix from any input to any output, per-channel gain, mute, delay and parametric EQ on both inputs and outputs, crossovers with Bessel, Butterworth and Linkwitz-Riley responses at 12, 18, 24 and 48 dB per octave, per-output limiting, BTL bridging across output pairs, and preset save and recall. As of August 2026 the Root series is supported natively in XSCACE Studio on macOS, which is where new installations should start. This editor is retained for installers running Root-series hardware already in the field on Windows, and is no longer developed.
