SMD DD-1+ Steve Meade Designs Amplifier Signal Distortion Detector Plus

The purpose of this tool is to enable the user to set the gain of an audio amplifier to match the source unit's output level, quickly and accurately. Proper gain overlap setting of a system ensures that no matter how high the volume of the head unit is, the user cannot excessively overdrive the system and cause damage to the amplifier or speakers.

Proper gain overlap setting also ensures the end-user is getting everything possible out of his/her system while minimizing unwanted noise. The DD-1+ can also be useful for detecting distortion in the audio signal caused by poorly designed or malfunctioning audio equipment.

This listing includes:
(1) The Distortion Detector PLUS (DD-1+)
(1) Calibrated Test tone CD
(1) Harness
(1) Manual

Feature:
- Sets audio system gain overlap, continuously variable from 0.0dB - 15.0dB in 0.1dB steps
- Checks gain overlap of an audio system without making any adjustments to the existing settings
- Verifies that the gain overlap of an install hasn't been tampered with after install
- Features our Patent Pending Distortion Detection system plus digital microcontroller and our proprietary firmware
- 200V maximum input (same as DD-1 HV)
- Quasi-RMS voltmeter (can detect clipping at any frequency)
