PAcalculate 1.3.2

Review of the Tool for Pro-Audio and Lighting Professionals:

• Includes 27 calculators covering 44 different calculations for tasks related to pro-audio sound reinforcement and lighting, in addition to offering reference information and utilities. Ideal for individuals involved with PA systems, sound reinforcement, sound engineering, pro-audio setups, and lighting.

Acoustics:

• SPL (Sound Pressure Level): Allows input of sensitivity in dB SPL, power, quantity of loudspeakers, phase, and distance.
• SPL sum
• Air absorption attenuation based on humidity, temperature, frequency, and distance.
• Ceiling speaker coverage
• Time vs Distance
• Audio frequency vs Wavelength: Includes lambda/2 and 2*lambda/3 calculations for line arrays or subwoofer arrays.
• Transition distance for line arrays (near to far field)
• Modeling for end-fire and broadside array subwoofers

Audio Electronics:

• Conversion between dBu, dBV, and Volts
• Q factor vs Bandwidth (B/W)
• Limiter threshold with attack & release time settings
• Amplifier gain calculation

Cabling:

• Calculations for speaker cables: low impedance, high impedance (constant voltage line - 70V/100V). Determines energy and level loss as well as system damping factor.

Lights:

• DMX channel setup
• RGB/RGBW/RGBA and CMY color mixing options

Additional Features:

• Includes valuable reference information such as pinouts (related to pro-audio and lighting) and graphical tools.
• Varied utility functions to assist with different aspects of pro-audio and lighting projects.
