SMD DD-1+ and CC-1 Combo Pack

The purpose and benefit of the D’Amore Engineering / SMD Destortion Detector PLUS.
The purpose of this tool is to enable the user to set the gain of an audio amplifier to match the source unit’s output level, quickly and accurately. Proper gain overlap setting of a system ensures that no matter how high the volume of the headunit is, the user cannot excessively overdrive the system and cause damage to the amplifier or speakers.

Proper gain overlap setting also ensures the end user is getting everything possible out of his/her system while minimizing unwanted noise. The DD-1+ can also be useful for detecting distortion in the audio signal caused by poorly designed or malfunctioning audio equipment.

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.

If you are familiar with our original DD-1 tool, the new / additional features of the DD-1+ are:
Fully variable gain overlap setting from 0.0dB to 15.0dB
Ability to check the gain overlap setting of an amplifier without making adjustments to it. (Great for checking a customer’s system if it returns for warranty reasons or a tune up) Also a great way to sell a tune up.
Input voltage capacity raised to 200Vrms (40,000 W into 1 ohm)
RMS AC voltmeter built in for reference
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 distortion detection circuitry is 100% analog, digital microprocessing system used for display and calculation of overlap
Distortion Detection trigger level > 1.0% Harmonic Distortion
3 stage autoranging for wide range of input signal from 1Vrms – 200Vrms. (40,000 Watts at 1 ohm)
Auto-shut off timer 8 - 10 minutes after ON button is pressed
Battery self-test and display of condition when DD-1+ is initialized

About the design
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:

They are readily available
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.

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
