Moving The Stage
Use this after you like your focus but want to nudge the image left/right. Enter inches and choose a direction; we’ll suggest small delay and level trims so TA alignment stays intact.

TEST TRACKS — PLAY OR DOWNLOAD
Broadband noise (log-equalized). Use for L/R level match and coarse tonal balance.
Confirms routing and side balance. Should come strictly from the left stage.
Mirror of the left test; match perceived level/timbre side-to-side.
Should lock dead-center on the dash. If it leans, tweak delays or trim near-side level slightly.
Correct polarity = tight, front-centered pulse. If hollow/smeared, fix wiring/polarity first.
Low→high sweep for measurement. Record with REW/ARTA/BARNIE to analyze FR, IR, decay & timing after your TA/EQ pass.
How to use these tracks (quick workflow)
- Enter distances (prefilled as an example) → Calculate. If the image leans, make tiny delay/level trims.
- Pink Noise (Full) at moderate volume → match L/R level; smooth obvious peaks with broad EQ.
- Pink Noise L/R → confirm channel routing & balance consistency.
- Mono Voice → verify center lock; refine by tiny steps.
- Polarity Pulse → correct any out-of-polarity driver before continuing.
- Dirac Sweep (optional) → capture FR/IR and fine-tune XO/filters.
Keep volume consistent between tracks (C-weighted slow if you meter). Save a DSP preset before experimenting.
