PAcalculate 與 Voltex Electrical 使用情況與統計
Over 42 calculations for pro-audio sound reinforcement and lighting, as well as reference info and utilities. A super handy tool for people dealing with PA, sound reinforcement, sound systems, electroacoustics, pro-audio and lighting
The app is very light (~1MB, like a typical mobile phone photo), works offline and uses no data bandwidth
More than 42 calculations spread across 26 calculators:
- SPL (sound pressure level). Enter sensitivity in dB SPL, power, number of loudspeakers, phase and distance
- SPL sum
- Air absorption attenuation for a given humidity, temperature, frequency and distance
- Ceiling speaker coverage
- Time «» Distance
- Audio frequency «» Wavelength (includes lambda/2 and 2*lambda/3 for line arrays or subwoofer arrays)
- Line Array transition distance (near field to far field)
- In-line (end-fire, gradient) array simulation with left/right mirroring
- Broadside (line) subwoofer array modelling with electronic or mechanical arcing and steering as well as end-fire/gradient(cardioid) lines
- dBu «» dBV «» Volts
- Q «» B/W (bandwidth)
- Limiter threshold (and times)
- Amplifier gain
- Speaker cable: low impedance, high impedance (constant voltage line, 70V/100V). Calculates energy and level loss, system damping factor
- Electrical and musical calculators that are related to audio. Unit conversion
- Lights: DMX channel, RGB/RGBW/RGBA and CMY
- Reference info:
Pinouts, proaudio (XLR, 1/4", 1/8", SpeakOn, DB25) and lighting (XLR3, XLR5) and graphs (Fletcher&Munson, microphone polar plots)
- Utilities (inclinometer, flashlight-needs camera permission that can be later revoked in phone settings)

Voltex Electrical is the manufacturer responsible for the design, build, certification, warranty, and distribution of Voltex products to the Australia and New Zealand markets.
We partner with leading global players in the production of switchgear and circuit control products, to sell quality product direct to Australia and New Zealand's electricians. Voltex's factory-to-you model, coupled with savings from having no shopfronts, gives Contractors a good recipe for business success and competitive edge.
Established in February 2001, we're achieving rapid, consistent growth by challenging the prevailing status quo in the industry's value propositions, and looking after contractors, the guys who do the work.
Well, it seems the electrical trade's massive corporate vested interests aren't that happy about online direct-to-tradie distribution, but we're not sorry. It's been a fun ride helping electricians make the move to buying online. It’s the m-commerce new reality. It fits well in an accelerating world because mobile commerce is growing faster than anyone ever imagined. And we think it's great.
