Distortion Detector/Analyzer for High(er) Voltage Systems

The purpose of the SMD DD-1 HV Distortion Detector/Analyzer for High(er) Voltage systems is to enable the installer/user to set the gain of an audio amplifier to match the source unit’s 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 also chosen a 9V battery as a power source for a few reasons. They are readily available and isolating the DD-1 HV from the vehicle’s electrical system for power, guarantees that it will only measure what it is supposed to measure; the audio signal, not noise in the charging system.

With the supplied harness RCA connections are used to make it easy to measure the output of a headunit directly, if you choose to do so, and should the harness become damaged it is easily replaceable or repairable in the field.
