Intusonic INTUFORCE 2 SDL 70 User manual

  • Hello! I've reviewed the user manual for the INTUSONIC 2SDL70 Stereo Audio Utility Amplifier. This document covers important safety information, installation procedures, technical specifications, and connection details. The amplifier has features like channel-specific level settings and filters, as well as input forwarding for mono operation. I'm ready to answer any questions you have about this device.
  • What should I check before connecting this product to any AC supply?
    Can I open this product for service purposes?
    What is the minimum total load impedance for the speaker output?
    What is the purpose of the High Pass Filter Switches?
