PA Align Pro: Soundcheck

Speaker delay, setups, Pro PDF

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Start with a basic soundcheck, calculate the delay between two speakers and save setups. A one-time Pro purchase adds advanced tools and PDF reports. Organize your PA soundcheck, calculate the delay between two speakers and keep setup records on your device. START WITH FREE OFFLINE TOOLS Record a basic setup and check connections, routing and levels manually. Enter each speaker's distance to the same listening position and the air temperature to estimate the geometric delay. A diagram and worked example explain the calculation. Save, reopen, edit or duplicate basic setups for the next job. UNLOCK PRO WITH A ONE-TIME PURCHASE Lifetime access, with no subscription. Pro adds: • A professional setup workflow with multiple speakers, known electronic latencies and advanced environmental inputs. • Limiter calculations for RMS voltage, a threshold in dBu and, with the required equipment data, dBFS and headroom. • Pink noise, white noise, sine tones and frequency sweeps. • Relative polarity comparison against a valid reference in the same signal chain. • Locally generated PDF reports with inputs, calculated results, assumptions, notes and recorded checks. Once activation is confirmed, Pro tools and reports also work offline. Purchasing and restoring require internet and the correct store account. Reinstalling may require a restore. Calculations depend on your inputs and equipment specifications; verify the settings on the actual sound system. The app does not apply DSP settings or guarantee speaker protection. Checks are entered by the technician and do not certify an installation. Relative polarity comparison can be inconclusive; it does not measure absolute polarity, frequency-dependent phase or acoustic delay. The generator's digital output level is not a calibrated SPL measurement.
