Introduction
Thank you for purchasing Acuma Labs’ Pro Audio Lab. This is a precision audio
analysis tool and sound generation software plug-in for the Mackie D8B digital mix-
er. It offers a broad cross section of sophisticated meters, noise generation devices,
and highly accurate instrument tuning references. Pro Audio Lab presents nely
calibrated stereo and mono level metering that simultaneously displays Clip, Peak
Level, RMS, VU, Loudness Peak and VU, Sum and Difference VU, Correlation, and
Loudness Balance meters. The stereo X/Y Phase Meter, Phase Scope, and select-
able (10 to 61-band) Spectrum Analyzer are portrayed by simpli ed and easy-to-read
display graphs that let you view and analyze your signal for concise and up-to-date
information. The built-in tone generators feature a professional oscillator with se-
lectable waveforms, a Pink and White noise generator, and Slate tone generation
with editable frequencies and burst times. Last but not least, Pro Audio Lab provides
you with “dead-on” tuning references (down to semi-tones and cents) for guitar, bass,
and piano with presets that include alternate tuning presets such as “open G, C,
Dobro,
capo, and 5 string bass.”

plug-ins. The UFX card is a 4-in/4-out architecture, which means it can support four
mono, two mono and one stereo, or two stereo sends simultaneously. Up to four UFX
cards can be installed in the D8B, allowing up to sixteen simultaneous single-channel
effects, eight stereo plug-ins, or combinations thereof.
