Someone recently told me he connected his vcr to his stereo system
and records music on video tapes, getting up to 6 hours per tape.

I have tried this with no success. The only outputs on my stereo are
the speaker outputs.

I unplugged the speaker wires. Then I plugged a couple RCA cables into
the speaker outputs and plugged the other ends into the front vcr
inputs.


Then I plugged the speakers into the audio outputs on back of the vcr
and set the vcr to Line 2.

When I turn the stereo on, playing an old LP, cassette or the radio,
the sound is rather disorted & there is very little volume.

After recording a bit, the playback has the same distortion and I
can't adjust the volume beyond what it was at when recording.

What am I doing wrong? The fella who told me about this said it worked
great for him. Unfortunately I didn't get his name, etc. so can't
contact him.

If your stereo does not have any jacks labeled "tape out", "record out",
"line out" then it will be very difficult to do what you want to do.
In a pinch, you can usually use the output from your stereo headphone jack
with good results....
.... go to Radio Shack and purchase the proper cord with the correct size
Stereo Phone Plug on one end and 2 RCA Plugs on the other.

#42-2483 1 / 8 " Stereo Phone Plug to 2 RCA Plugs
#42-2474 1 / 4 " Stereo Phone Plug to 2 RCA Plugs
When attempting to record on your VCR it will take some experimentation with
setting the volume level of your stereo to provide the best sound......
start at mid-volume and go either way to finally obtain the best level that
is compatible with your VCR audio recording circuitry.

I agree with Mr. sofie, but he did not mention afew things. Walmart also sells
very inexpensive name brand cables that are still good quality.

Two other things he didn't mention, probably in consideration of his schedule.
I also wish to add that Mr. sofie gives great advice. I just came in to expound
upon his suggestion.

In oder to understand what Mr. Sofie explained, I'll add a couple of basic
concepts to help clarify his suggestion (and a good one). This is also
presuming you have a stereo VCR.

1) when interconnecting devices, a powered and balanced signal always travels
from its output to its input.

Here is that tape monitor from stereo to VCR connection.
The line out (playback) of the stereo through the receiver's tape monitor
outputs goes to line in on the VCR. audio left line out of stereo goes to audio
left in on VCR.
audio right line out of stereo goes to audio right in on VCR. usually, the line
out of the stereo would be label line out and have jacks actually with white
and red color codes, signifying an audio connection. This establshed signal
allows you to record music onto your stereo VCR. This can be done because the
audio signal from the stereo is actually being sent to the VCR. The VCR
(through the audio line inputs) receives the signal and processes it through
its recording circuitry.

There is still a second set of connections to consider hooking up in order
to achieve playback signal from the VCR being fed back to the stereo receiver.

VCR line out to stereo line in connection.
The line out (playback) of the VCR outputs goes to line in (record) on the
stereo. audio left line out of VCR goes to audio left in on the stereo.
audio right line out of VCR goes to audio right in on stereo. usually, the line
out of the stereo would be label line out and have jacks actually with white
and red color codes, signifying an audio connection

2) If your stereo does not have a tape monitor connection in back, you can use
the headhpones jack at no higher than volume level 2 1/2- 3 1/2 as suggested
(for the volume control setting) in order to prevent overloading
(oversaturation of the signal). He explained the Y-adapter, so I will simply
say that the impedances on the y-adapter must match (32 ohms on the headphones
jack and about 1000 ohms on the line inputs of the VCR). The headhphone jack of
the stereo serves as a variable line output to go to another device that
processes audio. Just make sure to set the signal to the correct saturation and
after setting the signal (volume control) leave it alone.The signal will
process properly when at right amount of saturation and reproduce during
playback mode fairly well and faithfully.

I use headphones jack when recording from analog audio sources directly to my
stand alone CD recorder. works extremely well.

The Y-adaptor does not require any "matching" or "impedances" in or on it.
The headphone output will drive any load impedance from a bit below 32 ohms
to "infinity", i.e. it is a essentially voltage source. The 1,000 ohms VCR
input (or whatever, might be higher) is easily driven and no load matching
is required.
