Signal Flow - Universal Audio OX Operation Manual

Rigs
A RIG is a complete album-quality studio tone preset. Each OX Rig is comprised of
the various Dynamic Speaker Modeling, Dynamic Room Modeling, and Master Effects
settings. Six Rig presets can be instantly recalled with OX's front panel RIG knob.
Complete wireless Rig control is available with the OX app.
Rig Set
One Rig Set is a collection of six individual Rig presets that can be assigned to OX's front
panel RIG knob. With Rig Sets, you can quickly store your six favorite Rigs to the RIG
knob for standalone use without the OX app. Rig Sets are assembled and assigned to the
RIG knob with the OX app.

Signal Flow

OX has analog and digital signal paths. The reactive load and power attenuation circuitry
is pure analog — the tube amp's output feeds OX's reactive load and power attenuator,
which can then be sent to a real guitar speaker cabinet.
Dynamic Speaker Modeling, Dynamic Room Modeling, and UA master effects use stereo
digital signal processing (DSP) to generate the finished album-quality studio tones. The
output of the analog portion feeds the input of the digital path. Finally, the stereo path
is routed to the line, headphone, and digital outputs for monitoring and/or recording, as
illustrated below.

Outputs
All OX outputs can be used at the same time, and all OX output connections are optional
— you can mix-and-match any or all outputs as desired. For example, you can connect
a guitar speaker without connecting LINE / MON or HEADPHONE outputs, and/or use
headphones without connecting a guitar speaker. See
