eighty32 Toolbox

The complete field toolkit for AV, RF & broadcast techs — RF coordination, audio meters, calculators, and the biggest verified gear directories. Free, with optional Pro.

eighty32 Toolbox is the field reference and measurement suite built for AV, RF, and live-production technicians — everything you reach for on a show day, in one fast, offline app.

CALCULATORS

• Delay time (distance to ms), speaker & sub alignment
• dB math: SPL over distance, level summing, V/W, plus a full dB scale converter (dBu/dBV/dBFS, dBA/dBC)
• Ohm's law & speaker loads, power/current draw and breaker sizing
• Timecode & frame-rate math, frequency to wavelength
• OSHA/NIOSH noise-dose exposure timer

RF & WIRELESS

• Intermod & spacing analysis
• RF coordination engine: generate clean, intermod-safe frequency sets
• DTV channel lookup by ZIP to avoid local TV channels
• Manufacturer to model to band selection (Shure, Sennheiser, Lectrosonics, Sony, Audio-Technica, Wisycom)
• Coax / antenna cable dB-loss calculator
• SMPTE LTC timecode generator & reader

AUDIO METERS & TOOLS (best with a 2-channel interface)

• RTA + dual-FFT transfer function with coherence
• Loudness meter (EBU R128 / LUFS)
• SPL meter, phase/polarity & phase-correlation meters
• Delay finder (reference vs. mic)
• Signal generator (sine/pink/white/sweep)
• Input-level tester and 4-wire com test
• QLab-style playback / cue tab with fades, loop & ducking

REFERENCE LIBRARY

• Speaker directory: L-Acoustics, d&b, Meyer, JBL, Adamson, Nexo, Martin and more, with verified specs
• Microphone directory: Shure, Sennheiser, DPA, Neumann, AKG and others
• SFP transceiver reference with wavelength color codes
• Connector pinouts (XLR, speakON, DMX, DB25 and more)
• Color codes: resistor, fiber (TIA-598), AC mains wiring

eighty32 Toolbox is free to use. A one-time Pro unlock adds the advanced RF coordination, audio meters, and full directories. No subscription, yours forever.
