Our most popular gain setting tool.  Also good for sniffing out faulty equipment.  Find max clean headunit volume level, set processor / preamp gains, and amplifier gains.

The purpose of this tool is to enable the installer 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.

What is included?

  • The Distortion Detector (DD-1)
  • Protective silicon rubber boot
  • Calibrated Test tone CD
  • Harness
  • This manual
  • Pride of ownership

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 DD-1 from the vehicle’s electrical system for power, guarantees that it will only measure what it is supposed to measure; distortion in 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

DD-1 Great Tool

I had been using an O-scope but this is much faster, easier and more precise. It is either distorted or it is not. Definitely worth it…
