    Why is there no sound from channels 3 & 4 on my Soundstream Reference 705s with 2 channels of input?

      If you are not getting sound from channels 3 & 4 on your Soundstream Amplifier with only 2 channels of input, check the input settings on the bottom of the amplifier. The switch should be set to inputs “1 & 2”.

      If your Soundstream Amplifier repeatedly blows a fuse or frequently activates the Smart Power Supply Circuit, there might be several reasons: * Check your speaker configuration. The amp may be in “High Power” mode. If your subwoofer load is less than 1 ohm, switch the amp to “High Current” mode. * A speaker or its leads may be shorted, so check for shorts. * Ensure the amplifier has adequate ventilation.

      Wendy MathewsAug 17, 2025
      If channels 1, 2, 3, or 4 on your Soundstream Amplifier experience intermittent output, it could be due to: * Circuit breakers on these channels activating. Check for a possible short in the speaker wire or the speaker itself. * Verify the impedance of the load is at or above the rated minimum impedance for these channels.
