SMD DD-1 Distortion Detector/Analyzer by Steve Meade Designs

Get Rid of That Distortion

The purpose of the SMD DD-1 Distortion Detector/Analyzer by Steve Meade Designs is to enable the installer to set the gain of an audio amplifier to match the source units output level, accurately and quickly. It can also be useful for detecting distortion in the audio signal caused by poorly designed or malfunctioning audio equipment.

SMD has chosen a 9V battery as a power source for a few reasons. They are readily available and isolate the DD-1 from the vehicle’s electrical system for power, guaranteeing it will only measure what it is supposed to measure; the audio signal, not noise in the charging system. The supplied RCA connection is used to measure the output of a headunit directly, if you choose to do so. Should the harness become damaged it is easily replaceable or repairable in the field.
