Routing

Stereo, Wet/Dry and Dual-Amp Effects Rigs

Multiple outputs create value only when every downstream channel remains distinct, safe and phase-coherent.

Research guide · Updated July 27, 2026

Define the destination channels

Two processor outputs need two amplifier, mixer or interface channels to preserve stereo. A wet/dry rig needs a clear decision about which path carries dry signal. Label outputs and verify what happens when a venue accepts only mono.

Manage phase and grounding correctly

Parallel paths can cancel when summed if processing changes polarity or timing. Dual amplifiers can also create ground loops. Use transformer-isolated, phase-capable equipment intended for the job and never remove safety grounding.

Build the mono version first

Create a complete mono sound, then add width or a second voice. Test the stereo rig summed to mono and with either channel missing. This keeps a routing constraint from erasing the core part.
