- 100dB Logarithmic decibel display so it can show the full audio dynamic range
- Linear display to show music dynamics similar to a VU meter
- Fast peak detect mode to identify when an amp will be clipping.
The huge dynamic range of its log decibel scale shows you everything from 500 watts RMS, down to less than one millivolt. It’s so sensitive that, when your amp is off, it shows deflections from conversation in the room as your speakers work like microphones! It shows the whole range, while maintaining a resolution of one dB.
Use peak detect mode to accurately detect clipping of even the shortest peaks found in music. Averaging mode lets you measure continuous power and noise.
The variable decay time control lets you set the meter to capture transients for accurate peak readings or to respond rapidly to show music dynamics.
Variable illumination lets you adjust brightness for varying residential lighting conditions (such as TV viewing).
The supplied files package gives you all of the graphics files needed to print excellent artwork for the PCB, front panel, meter scale and more. We’ve even included the original CorelDraw source files, so you can customize the project, if you like. Get the full article, schematic and files here (free!):
