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.
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.

These tools are a MUST have. Affordable (way more than unintentionally blowing a set of $1000 speakers), maybe your system has a problem you don’t know about like your amp has an issue and clips all the time or as in my case one of my JBL 670 crossovers was bad. While setting the gains with all the speakers unhooked smoke came pouring out of the crossover. Didn’t do that to the other 7, apparently that one was a dud, my amp seems to have survived the short thankfully. Don’t just think your system is great, and is as loud and clear as it can be buy these and KNOW it is! Awesome stuff from D4S as always.
