Steve Meade Designs Dd-1+ Distortion Detector/Analyzer

SMD DD-1+ Steve Meade Designs Amplifier Signal Distortion 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 , quickly and accurately. Proper gain overlap setting of a system ensures that no matter how high the volume of the head unit 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. This listing includes: (1) The Distortion Detector PLUS (DD-1+) (1) Calibrated Test tone CD (1) Harness (1) Manual Feature: – 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) Specifications: Distortion Detection trigger More Than 1.0% Harmonic Distortion The guaranteed operating range of the input signal is 1.2Vrms – 200Vrms. (40,000 Watts at 1ohm) Autoranging Low Battery LED trigger battery voltage Less Than 6.5Vdc Auto-shutoff timer 8 – 10 minutes after ON is pressed Battery self-test and display of condition when DD-1+ is initialized Dimension: (LxWxH) 9 x 6 x 2 inches
