The purpose and benefit of the D’Amore Engineering / SMD Distortion Detector.

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; 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

• The Distortion Detector’s circuitry is 100% analog
• Distortion Detection trigger level > 1.0% Harmonic Distortion
• Guaranteed operating range of input signal is 1.2Vrms – 125Vrms. (15,000 Watts at 1 ohm) Autoranging
• Signal Present LED trigger voltage 750mVrms
• Low Battery LED trigger battery voltage < 5.6Vdc
• Auto-shut off timer 8 - 10 minutes after ON button is pressed
• 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.

What is included?

• The Crossover Calibrator (CC-1)
• Protective silicon rubber boot
• Calibrated Test tone CD
• Harness
• This manual
• Pride of ownership

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 Crossover Calibrator’s circuitry is digital microprocessor controlled
• Crossover -3dB point accuracy +/- 0.25dB
• Low Battery LED trigger battery voltage < 6.5Vdc
• Auto-shut off timer 8 - 10 minutes after ON button is pressed
