The purpose and benefit of the D’Amore Engineering / SMD Distortion Detector (High Voltage).

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-1HV))

Protective silicon rubber boot

Calibrated Test tone CD

Harness

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

Specifications

Everyone hides these in the back of the book. We are proud of our specs, they aren’t lies, so we are putting them up front.

The purpose and benefit of the D’Amore Engineering / SMD Crossover Calibrator.

Most modern car audio amplifiers have a built in crossover on the side. Usually, it will start at 30hz and have a huge gap, all the way up to (sometimes) 500hz. The purpose of this tool is to enable the installer to set the crossover frequency of an electronic crossover to the desired frequency, accurately and quickly. Enter "Competition Mode" and easily match gains on any 4-channel amplifier or even multiple bass amplifiers. This is VERY important when using subwoofers that share a common chamber, especially if you have 2 (or more) amplifiers on a dual voice coil driver.

When you pick up the CC-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:

Isolating the CC-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.
