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.
 
Sets audio system gain overlap, continuously variable from 0.0dB - 15.0dB in 0.1dB steps
Checks gain overlap of an audio system without making any adjustments to the existing settings
Verifies that the gain overlap of an install hasn't been tampered with after install
Features our Patent Pending Distortion Detection system plus digital microcontroller and our proprietary firmware
200V maximum input (same as DD-1 HV)
Quasi-RMS voltmeter (can detect clipping at any frequency)
