If treated as such it should provide you with many years of reliable service. We have chosen a 9V battery as a power source for a few reasons.
Isolating the DD1-1 from the vehicles 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. We also chose an RCA input connector for a few reasons. It makes it pretty easy 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. The Distortion Detectors circuitry is 100% analog.
