The OM-1 can be used as a real time indicator of how close to clipping your amplifier is being driven (when calibrated with the SMD / D’Amore Engineering DD-1 Distortion Detector) and / or as a light show to add a visual sense to your music. Adding a visual sense to your music is great, as long as it is perfectly in sync. With the use of high speed circuitry in the OM-1, the response is instantaneous.
About the Design
Some might consider the OM-1 to be over-built; we think it is just right. Some features of the design are:
- Mil spec FR4 circuit board
- Regulated power supply
- Constant LED current and brightness regardless of battery voltage (won’t dim with your beat)
- 20 bright surface mount LEDs
- Wide operating voltage range for vehicles with modified electrical systems
Specifications
- Operating voltage range for power supply…………………………………………..8-22 VDC
- Input Sensitivity……………………………………………………………………………… Adjustable
- Voltage required on speaker input for full scale @ maximum sensitivity ….10 VAC RMS
- Voltage required on speaker input for full scale @ minimum sensitivity……150 VAC RMS
- Maximum Input………………………………………………………………………………..200 VAC RMS
- Dimensions…………………………………………………………………………….…2.75 X 2.75 X 0.6 Inches

Really an awesome meter. You can match it too your amplifiers gain using a DD-1 Distortion detector or O scope.
Does not matter which gain overlap you have chosen to set your gain, you will always see how much you can push your system and prevent clipping. I’ll take two please! one for the bass, and one for the front stage
