AV Toolkit

Professional audio and AV calculators

A clean multi-page toolkit for speaker coverage, SPL loss, rack power, amplifier sizing, voltage drop, cable gauge, projector brightness, and viewing distance.

Speaker Coverage

Estimate horizontal and vertical coverage footprint from throw distance and coverage angle.

Open

SPL Distance

Estimate SPL loss over distance using free-field inverse square law.

Open

Rack Power

Estimate current draw, circuit loading, and recommended branch circuit count.

Open

Amplifier Wattage

Get a fast amplifier power target from speaker RMS and headroom strategy.

Open

Voltage Drop

Estimate drop over copper conductors for fast field decisions.

Open

Cable Gauge

Find the smallest AWG that stays within your drop target.

Open

Projector Brightness

Estimate screen brightness in foot-lamberts and nits.

Open

Screen Viewing Distance

Estimate screen dimensions and near/far seating distances.
