Product Description:

Ensure precise gain adjustment and protect your amplifiers and speakers with the SMD DD-1+, Steve Meade Designs’ Amplifier Signal Distortion Detector Plus. Its Patent Pending Distortion Detection system identifies clipping and distortion from poorly designed equipment, while a continuously variable gain overlap (0.0–15.0dB in 0.1dB steps) lets you optimize system performance without introducing noise. This complete kit includes everything needed for professional-grade installation verification and superior audio quality.

Features:

• Continuously variable gain overlap adjustment: 0.0–15.0dB in 0.1dB steps


• Detects distortion and clipping at any frequency with Quasi-RMS voltmeter


• Patent Pending Distortion Detection system with digital microcontroller and proprietary firmware


• Verifies gain overlap without altering existing settings


• Confirms install integrity post-installation


• 200V maximum input, compatible with high-power systems


• Auto-shutoff 8–10 minutes after activation


• Battery self-test and low-battery LED indicator

Specifications:

• Distortion Detection Trigger: >1.0% Harmonic Distortion


• Input Signal Range: 1.2Vrms – 200Vrms (autoranging)


• Low Battery Threshold: <6.5Vdc


• Dimensions: 9" x 6" x 2"
