- Page 2 (except this looks a lot nicer than what a typical audio tech could put together, most of them aren’t this artistic!) This manual is for the “standard” version of the Rapaudiology VUs. Custom built units will vary slightly with other options and features.

- Page 4 Meters and their lights are either on, or not. Signal passes through to outputs (labeled “thru”) even when the unit is switched off. Use a small flat head screwdriver (⅛”) to adjust each meter’s needle balance screw if needed. The only reason to adjust this screw is if the needles are not resting at -20 on the scale. Select a position you want to calibrate/monitor by selecting its position on the switches at the rear (both switches have to match positions for the meters to work).
- Page 5 The unit is powered by a 12 volt DC plug pack. If replacement is necessary, make sure the new plug pack’s connector supplies + (positive) to the tip, - (negative) to the sleeve. Analog VU meters and RMS Mechanical VUs give an approximation of voltage level RMS (Root Mean Square). When feeding them a sine wave tone, VUs will display RMS accurately since the signal isn’t complex.
- Page 6 Calibrating the unit using 1kHz sine wave tones: If you don’t already have a full scale 1kHz tone (0dBFS), you can download one here: www.redsecta.com/1ktone.zip 1. Import the 1kHz tone audio file to an audio track in your DAW. Important: make sure your monitors are turned off or way down, you don’t want to play this tone at unity gain...

needles may occasionally go over 0 VU during sections that have more energy, like a sustained 808. Keep in mind that often times, one channel will have more energy than the other, so both meters will be off slightly when you compare your settings against the 1kHz tone. Another thing to keep in mind is that material with more low frequency energy and slower transients will drive the needles on the VUs more than material with higher frequency content and fast transients, which is often perceived as louder than material that is more bass heavy.
