    I am using this with a stereo.

  • rpg007 Sep 26, 2008

    I would add that initial contact from vocopro was a capacitor was the problem. am hoping I can repair myself with good instructions. thanks

  • rpg007 Sep 27, 2008

    Thanks for the help.. I have hooked it up to my stereo and tested dvds and cds and cd+gs.. all of which play properly, but very, very low volume. I connected to both sets of available audio outputs on the DVX-880pro with the same result, very low sound. One thought from vocopro was a bad capacitor connection. It is not under warranty (bought used) and since I am not uncomfortable around electronics (and have a general knowledge and a good neighbor who can help me if needed) I was hoping someone could tell me where to look and what to do in general to isolate and repair the problem.

    I took it apart and see what you mean.. I'll give it a crack but perhaps I am in over my head.. we'll see.. thanks -- the info was helpful and certainly worth the token I had to pay..

    All the best!

    looks like the microphones are working perfectly.. just the sound from the CD or DVD isn't very loud.

    The cause might be the Transistor, radio which is present in the circuit, A NPN or PNP transistor which supply the voltage and make it amplified.

    Find out the faulty transistor, transistor are Three pin small mostly Black in color item, similar to the Capacitor And then replace it.
    For checking you need to have the Multi-meter.

    The following website are carrying useful info about transistor:

    1. General instruction


    Let me know if you are able to find out the fault in the circuit, othewise I will help you out with more useful information.

    Try testing the Transistor with the Digital Multimeter if you can.

It seems its preamplifier is faulty. Mostly repairs are unfortunately not cost effective.

I have a Boss 4x50watt in-dash stereo, 2 Pioneer 270-watt max/ 40 watt nominal rear speakers, and 2 Pioneer 500 watt peak/ 80 watt rms front speakers. Do I need to buy an amplifier? Or is does the head...


You do not need to buy an amp, the only reason to buy one is if you do not think it is loud enough when you turn up the volume to max. The speakers you have can take more power than your stereo can provide, but you only need to add an amp to get more power if you want it to play louder than it does now.

No picture, no sound


see the troubleshooting index:God bless you


No sound
1. Check if the TV and Amplifier (if connected) is turned on and set correctly.
2. Check if the TV, DVD player and Amplifier are connected properly.
3. Make sure the TV, DVD player and Amplifier volume are not set to Mute.
4. There will be no sound output during Reverse Play / Pause / Step / Slow / Search.
5. If the DTS soundtrack is enabled in the DVD Disc Menu, but you are using Stereo Analog audio, the sound will not work. Try switching the soundtrack to Dolby 5.1 or PCM mode in the Disc Menu.


Does not play disc
  1. No disc. - Load a disc into the tray.
  2. Disc has been loaded upside down. Place the disc with the label side up.
  3. Disc region code does not match region code of the player.
  4. Disc type is not the correct type to play.
  5. Disc is damaged or dirty. Clean the disc or try another.
  6. Moisture may be condensed inside the unit. Remove the disc and the leave the power on for one or two hours.

Very low volume on all drums.


I don't think there is anything wrong, it has a very low line level output intentionally. This is to minimize distortion to an amp or mixer. Mine is the same and also a different brand. It is actually made so you could play it through a stereo without damaging it.

I have a sa-ak320 stereo that was left at my gf's


The 6 ohm speaker would make it slightly louder but won't solve the problem, you are right the stereo has bad audio output ic, and there is trouble with the cd player. I would use it until it goes, and get a brand new unit, not cost effective to repair.

Low volume and unbalanced deck


Turntables require amplification, they have very low output on their own. If your Sherwood has an Aux input try using that, older receivers often had a built-in pre-amp on the aux jack. You can obtain a stand alone pre-amp for less than $50, I use one from mcm, #40-630.

97 Jeep Grand Cherokee Limited Stereo problem


If you still have audio but unable to turn the volume, there are 02 possible problem:
- the volume control is defected will not respond ( electronic volume control; need logic low/high to activate the audio )
- the front control PCB is broken ( can be fixed if there is a small cracked )
If no audio at all then most likely audio output IC defected
