Hello to all. I am attempting to set up a multi room system in my wife's salon. I am not looking for symphony quality sound, mostly just background noise for the stylists. I bought an Onkyo receiver and a monster speaker selector from Circuit City, and a few pairs of speakers. My question is, is there any way to adapt the left and right output into a mono output to send to the speakers?

Is there a "Mono" switch on the Onkyo???

No, unfortunately it isn't that easy. It is a lower end receiver, as we are trying to start a business, it only has tone, bass, and balance for audio controls.

Speaker-level stereo to mono converter

Dunno how the load matching works on the transformer output though. I'd image you'd have to connect the speakers in a series/parallel arrangement to present roughly an 8 ohm load - unless your speaker switch is an impedance-matching type.

Just for background music, it might be easier to return all this stuff and look into a small 70v distribution system.

Just because there is a knob doesn't mean you should turn it.

It does have tape 1 and 2 inputs. Thanks for the link on the converter.

Can you return the speakers?

Several companies make "Stereo Input Speakers" for such applications as yours. I installed one in the kitchen and wife's office... do a nice job.

Check these out.

Does it have a "tape (rec) output"???

If so, get one of these for $4: (2xRCA male to 1xRCA female)

and one of these for $8: (2xRCA male to 1xRCA male)
  • Plug the two adapters together.
  • Plug the two RCA connectors on one end to the Tape OUT (Rec).
  • Plug the two RCA connectors on the other end to the Tape IN (Monitor).
  • Press/select the "Tape Monitor" on your receiver.
Everything will now be in MONO.

NO!!!

...do not combine line-level inputs without isolation.

On line-level, you use a summing circuit; 1Kohm 1/4 watt resistor on the center conductor is the important part; I built one once with a plastic project box & 8 jack rca piece; it allowed me to have a mono output which I doubled for my purpose.
