HI, very possible. Just follow this instruction:

All yo need to use for the connection is to get an RCA TO STEREO JACK HEAD (use the google image to see the type of cable).. Connect to denon 700aedab, make sure that the denon 700aedab is on either aux, tunner,video,etc. Those auxillary options on your denon 700aedab.

Connect the RCA into the aux of the denon 700aedab and connect the small jack head into the laptop ( where you plug in earphones),and play and enjoy your music.

If it does not play with aux try tunner, or video, one mustplay,and if it does ot play any, that means either the port of your laptop or the denon 700aedab port is faulty.

And don't forget to connect the speaker,because diffidently you will sure hear absolutely nothing with out the speaker.

Feel free to pass your comment .

Thanks for using fixya.

check if left speaker is shut off /connections one speaker my be on a side the other on b side check all speaker connections

Which output section of the Denon are you using? Tape monitor out? And are you getting sound through the speakers (not the PC speakers) that are attached to the Denon speaker terminals?

hi there might be some problem with the link that u have hooked up with the speakers.

Hi,

Have you unplugged it from wall since ?
and, do you know if maybe the speakers are blown?
Bad speakers will make it stay in "protect"
Try other speakers after the unplug-plug back in routine.
Try the Denon website for a manual

Did you "enable" this input on your Denon? After seeing it, you still need to enable it in souce

I have repaired many of these Denon receivers over the last few years.

Since the headphones work, that means if you dis-connect the speakers it will turn on and not go into protect (when power cuts off a few seconds after turning the unit on).

The most likely problem is a bad speaker. to find out which speaker is causing the problem, do this.

Start out with just one speaker connected and then turn on the unit. If it turns on and plays music, you know that speaker is good.
Now turn the unit off again and add another speaker and keep the first speaker connected. Once again, if the unit plays, that speaker is also good.

Keep doing this same procedure one speaker at a time. As soon as you connect a speaker and then try to turn on the unit and it goes into protect, the speaker you just connected is bad.

To confirm that this speaker is the bad speaker, dis-connect all speakers and only plug the suspected bad speaker into a speaker jack that worked with one of the other speakers.
If the unit still goes into protect you know then that you have found the bad speaker.

If the unit still goes into protect, that speaker is bad and you will need to take it in for repair or replace it.
make sure you use 8 ohm speakers. if i remember correctly these Denons can use 6 ohm speakers, but those are harder to find and most home speakers are 8 ohms.

If the unit does not go into protect and that suspected bad speaker plays in one of the other speaker jacks, what you really have is a bad channel in the amplifier, the channel that the suspected bad speaker was previously connected to.

If you find out you have a bad channel, you will need to take it in to an repair center. Preferably an authorized Denon service center. There are not very many of those around. I work at the only authorized Denon service center in the entire state of Michigan.

If I can be of more assistance, don't hesitate to ask. And a good rating is always appreciated. :)

Get the adabtor that can take the headset output and convert it to compatible connections for your sound system. I believe your sound system uses the RCA phono plug type connections.

Places like Radio Shack should be able to help you with what you need.
