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.


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
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
