Kenwood VR615 turns itself off at medium volumes

Start with the basic setup in the manual. Test tones - work or not?

NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING.

Turn the volume control to something medium.

The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

hello ,i strongly suspect the units protect circuit is sensing a speaker problem.Listen to each speaker to see if all the drivers(woofer,midrange,tweeter) are working and if so are any of them sounding distorted.When an amp is damaged it wont play at all,sounds like a bad speaker to me.

its more than that i think you have either turned your speakers a/b off or have blown up the sound valve i would send it in for checking by a ppro as no adjustment would be needed to get at least some sound

Sounds like the music amplifier is different to the tuner audio amp. The music amplifier is now looking at an unbalanced impedance which is less than it should be. Therefore the output chip of the music amp has more current through it than it wants so it gets hot and shuts down.Put a four ohm wirewound resistor ( from Radio Shack ) in series with each surround speaker to reduce the current flow through the amplifier output.

The regulator is bad.

you probably have a bad switch. you need to use a multimeter and check the resistance of your volume up switch, if less than a few meg., the switch is bad.

This is an indication of protect mode. One thing to test here:

Does the unit shutdown only when you change volume? If you try turning up the volume really slowly, will the unit remain on?

Thanks,

You need to make sure you ohms are correct if there too low this will happen to protect the amp.

Do you have the ipod turned up too? Whats happening is the alpine is getting to low of a foltage signal.

u sure when u go to 0 is it loud ? unplug it then back in reset all in menu
