Default Impedance Mismatch Correction

Hi, I have a DVD combination Amp/Player (Sony DAV300) that I also use
to play CDs on and I wish be able to hear the music in another room
(kitchen) as well as in the room with the Amp/Player. I have run a
good quality speaker cable between the rooms which is about 20 feet
long. I have taken an audio output from the DVD player (output
specification 2V 1 Kilohms Impedance). At the remote location I have a
set of active speakers, they were originally on my computer but their
discrete size and colour allows them to blend in to their
surroundings. I do get sound through but the quality is poor with lots
of distortion, I believe I have an impedance/voltage mismatch issue. I
have taken a phono output from the DVD player and everything works
fine but taking this output switches off the speakers in the DVD room.
I believe computer speakers have an input impedance of around 4-40
ohms generally. Can you suggest how I can fix this problem?


Feeding a 1kohm output into a 4-40ohm(?) input is a no-no. It's the
equivalent of a short. Get the real numbers and check back.
