Connecting my DVD RCA jacks to the Aux-In of the Stereo

[Geoff Schultz]

I am trying to figure out what I need to do to get my DVD player to play
through the Aux-Input of my in-dash CD/Stereo. I want to have stereo
output through the stereo instead of utilizing the TV speakers.

The DVD player has RCA jacks for audio output and if I connect them to the
Aux-In of CD player, all that I get is a loud buzz. Connecting it to the
audio input on the TV works fine. Plugging other devices into the Aux-In
is fine, but not the DVD player.

Any suggestions as to what I have to do to make this work?

The DVD only has RCA jack outputs. It plays fine through the TV but
when we try to play it through the Aux In on the stereo it just
generates a buzz. The TV has no audio outputs. I think that we have
some mis-matched impediances.

P.S. We're headed to the boat next Wednesday and then you'll see new
7knots logs. We hope that all is well with you & Susan.

Buzzing indicates a ground loop. Mismatched impedance will manifest
itself as weak/loud/distorted sound.

Google for "audio buzz ground loop".

Use this between the DVD and the stereo:

Thanks for the info. I'll give it a shot when I get to the boat.

Get a 12v DVD player. It's the inverter causing you the trouble. I'm not
at all confident that you'll be able to effectively eliminate it on the
boat. I've got a 12v player in our 348 Vista and it's great. I actually
use the AUX-in on the DVD player to daisy chain input from an iPod.

That and you're likely to get better battery life using a 12v player anyway.
But if the player already uses an external power supply you may be able to
use a DC-to-DC transformer to adapt to whatever voltage it needs. But if
you want to just cut to the chase and get things working I'd dump the
AC/inverter setup and just get a player designed for auto/rv/marine use.

I've been through about 3-4 DC based DVD players and haven't found one that
compares to the AC based Sony that I settled on. The Sony plays everything
flawlessly. I'll work on it from the isolation standpoint. If the problem
is a ground loop, it seems that there's no reason to assume that the
isolation transformer won't solve it.

Geoff,
Do other audio devices work with the stereo on the same input you are
using for the DVD? Maybe the problem is not with the DVD but is with the
stereo.

I feed my Sirius radio and SSB (so we can listen to the nets while we
have breakfast in the cockpit) through it. Both are fine. I have an
isolation transformer on order which will be waiting for me in Ft.
Lauderdale when I get there next week.

TV and DVD player. In fact, I think it was recommended to me in this
google group.

Ahum, this is NOT a google group. You may be reading it through Google,
but the USENET predates Google Inc. by a few decennia...

Try googling for "usenet is not google groups"
