RCA JACK CONNECTION QUESTION
MASON
I have a stereo receiver that has + - connection for each
speaker for a total of two speakers . I am attempting to connect these
two connections to an amplifier that has female rca inputs . My
question is can I snip the ends off of two rca cables and run wires
from the + - connection of each speaker to the exposed wire of the
snipped off end . I thought when I snipped off the ends there would be
two wires exposed one for the inner pin of the rca jack and one for
the outer shield of the rca jack (ground). What I have found is one
single strand of wire which confuses me as I thought that + and - had
to be seperated. I do not want to damage my receiver so I am afraid to
experiment.
Any help would be deeply appreciated .
Thanks Mason

NO, do not connect your receiver speaker outputs to an RCA line input of an
amp...... not only will you end up with hum, distortion and signal level
problems BUT it you accidentally reverse the polarity and ground out the (+)
terminal of the speaker output you can "blow" your receiver's amplifier
section..... big bucks to repair. Yes, you can easily damage your
receiver.....
You would be much wiser to use the TAPE OUT or TAPE REC output jack on the
back of the receiver...... not only will these output jacks be of the RCA
type but it will also be the correct "line" level and impedance to feed into
the RCA jacks of the AUX input of your amp. You can then use standard
RCA/RCA patch cords.

Could we please say "do not connect directly, use a suitable interface
box with an attenuator, thank you very much.

Worst case yes.

No he will not, the questionee appears to want the signal after the
volume control. In which case the reply is:
USE THE HEADPHONE OUTPUT, it is a suitable line level signal, albeit
possibly somewhat strong, so take care with the level adjustment.

Stereo jack -> pair of phono adapters do exist on the marketplace.

It will not be regulated.

As with the adapter plug described.

Hmmm ... anyway, the questionee appears to have overlooked the shield
when cutting a cable. Again: the correct reply that addresses the
required functionality is to use the headphone output because it is
suitably attenuated and resistor-buffered.

out the headphone connection to two RCA jacks. Radio shack sells them. Use a
regular RCA cable to complete the connection. Crude but effective - and
there's already limiting resistors built-in to the receiver.

Thanks for all the ideas,your all very knowlegable . I am going
to go with the headphone jack idea as the tape out does not let me
control volume as a previous poster stated and the stereo amp does not
have a volume control . One more question to clarify things if I may.
I pulled back the boot if that is what it is called on the rca jack
that I snipped off and did notice two wires . One wire to the inner
pin and one wire to the outer shield, ground I assume. My problem is
theses two wires seem to join together in the wiring part of the cable
between the two ends . I thought like I stated prevously that + and -
on a speaker connection had to be kept seperated . Am I incorrect in
stating this from viewing the snipped off rca cable ? Just looking to
learn something .
Thanks Again Mason

Yes, you are correct with your thinking..... the wires must not touch each
other and create a shore between the inner conductor (+) and the outer
conductor (-). This applies to any RCA plug or jack connection but is
especially important with the speaker connections.
Radio Shack has "ready made" cords that will allow a simple, clean, and
cosmetically pleasing connection from the headphone jack to dual RCA
connectors.
