About the design
When you pick up the DD-1, know that you are holding a precision piece of equipment. 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:
- They are readily available
- Isolating the DD1-1 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.
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
