In Reply to: Re: Connecting a cd player to a receiver with only phono input posted by Mike B. on March 02, 2000 at 07:47:58:
Mike is right. You can plug the CD player into ANY other input jack that the receiver has to offer other than a phono jack. The CD player just puts out WAY too much signal and is overloading the receiver's phono section.If you don't have any other inputs available, you'll either have to manually disconnect either the tuner or cassette's inputs and swap the CD player's cable's into that jack. You could continue to do this until you get tired of it or go to Radio Shack and pick up a switchbox.
You would have to hook up the switchbox into the tuner jacks and then connect the tuner and CD to the switchbox. Once the receiver was put into the tuner mode, you would simply switch between the tuner or CD player from the external switchbox as you desire.
There is another solution. You could upgrade to a receiver that has more inputs : ) Sean

Thank you VERY much...exactly what I needed to know!
Hi Lori.Before you give the switchbox a try, you can also try the following:
1. Are you using the rec-out to send a record signal to your cassette tape machine, or do you just play back? If you don't make recordings, then consider plugging the CD player into the rec-out jacks and leave the machine on all of the time. This 'may' reduce the volume level of all of the other inputs because the CD's output impedance will impinge on all of the other sources. And, the CD will play through the other signals (but only when you play a CD -i.e. not when the player is at idle). Remember, when you turn the CD player off, it may short out the other inputs. Or, it may actually cause the levels of the other sources to return to their previous state -but this is less likely. Move the input selector switch to Phono (which is unused, to play back a CD).
2. A simpler option is to share the auxillary input, using a set of Y jacks.
3. If you are not too worried about how things sound, get yourself a set of attenuated input cables. 20dB attenuation is standard for this type of situation. Then you can use your phono input jacks. The sound will be a bit heavy in the bass and shy in the treble.
4. Check the back of the receiver. If it is really old, it may have a switch for crystal-ceramic/magnetic cartridges. Move the switch to the crystal/ceramic position and plug the CD player in directly.
Good luck

A simpler option is to share the auxillary input, using a set of Y jacks.Assuming that the cassette deck is plugged into the tape inputs (or why bother with the tape loop), that leaves the tuner and CD player to be plugged into the "Y" connector. Unless the tuner has an attenuation control (most don't), it will be constantly outputting a line level signal. Ain't gonna sound too good when listening to CD's.

If the receiver's RIAA equalization is even halfway decent, "a bit heavy...shy" is not quite correct. Try removing the tuner, and plugging the CD player into the Aux input. Then turn the bass control all the way up, and the treble control all the way down, and listen to a CD. That's about what the sound will be like (after attenuating to avoid the overload).

Although that will take care of the overload problem (for the most part) it still doesn't take the RIAA equalization out of the picture.
Short of buying a new receiver, the best solution is to swap cables into the Aux input depending on which you want to listen to. The next best would be to get a switchbox, which while inelegant, is the cheapest route to avoid having to swap cables.

Hey, wait a minute. Is this an integrated or a receiver? If there is a separate tuner input, then the simple solution is to share that input on a Y connector. You can turn the tuner off... ah, the whole thing is ill founded.Of course the RIAA curve is bound to be messy. The bass will be tubby and the treble will be threadbare. With some CD players this might be a bonus. Re. the ceramic thing - 50/50 on this: Some circuits have EQ for the ceramic inputs, others don't. I don't know how Sansui handled this, if at all. If the receiver is less than 30 years old, it probably doesn't allow for the use of ceramics (which some call the poor man's MC).
What is on the AUX, anyways?
Tweak tipsters know that the rec-out is the closest thing to hotwiring the input -you bypass the selector, after all.
I was told by another that I could buy a "cassette to cd car kit". Plug the tape into the cassette and the connector into either the headphone plug of the cd or the outputs on the back. This seems like the simplest solution...or buy another receiver. It is an old Sansui stereo cassette receiver so the only output is for phono, not even an auxiliary. The cd player is an Onkyo R1.Thanks so much for coming up with solutions.
Do you mean to say this this receiver is an all-in-one unit with Cassette built in? I think that these were called cassceivers.The adapter that you mentioned will certainly work. It is made to be used in car stereos and can take any line level signal.
But, for all of the bother, you might want to check out your local pawnshop. There are plenty of stereo receiver 'orphans' out there that can be had for a few dollars more than what the adapter will end up costing.
You can built an Inverse RIAA filter as described on the link below.
What it does is EQ and pad down the signal from your CD to match what
you would get from a magnetic phono cartridge.http://www.hut.fi/Misc/Electronics/circuits/phono.html
Thanks for the tip. I don't know whether Lori would be interested in taking things this far, and since the inverse network is combined with some padding down, it would meet her needs nicely.I will add the URL to my own list of interesting DIY projects.
