About: SMD DD-1+ Distortion Detector Plus 

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.

About the Design

When you pick up the DD-1+, know that you are holding a precision piece of equipment.  If treated as such it should provide you with many years of reliable service. 

What is the difference between this and the original DD-1+?

  • 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 level > 1.0% Harmonic Distortion
  • Guaranteed operating range of input signal is 1.2Vrms – 200Vrms.  (40,000 Watts at 1ohm) Autoranging
  • Low Battery LED trigger battery voltage < 6.5Vdc
  • Auto-shut off timer 8 - 10 minutes after ON button is pressed
  • Battery self-test and display of condition when DD-1+ is initialized
  • Shipping Box 9 x 6 x 2 inches, 2 lbs
