LED Meter is a handy utility module designed to show audio levels. Five color versions are available:
- all blue color
- all yellow color
- green color with yellow-red peak segments – silver panel
- green color with yellow-red peak segments – black panel
- yellow (positive) and blue (negative) bipolar version
There are total 30 led segments, each one roughly corresponds to 1 dB of level, so it is 30 dB of measurement level available with this module.
Dual color version (blue-yellow) and green color version sold since 2019 year have mode jumper on the back side. When the jumper is installed – bipolar operation is active, and when the jumper is removed – ordinary audio meter is active.
The module has an input for the signal to be displayed, and its buffered copy is sent to the output for further processing, so no external splitter is needed.
Two trimmers are accessible via holes on the front panel: left trimmer adjusts brightness and right trimmer is used for the level adjustment. So the module can represent full scale signals ranging from 2 V to 12 V.
