Missing the input 1 and 2 cables

You need a set of normal rca cables (red.yellow,white) and another single rca cable..
OPTION 1 :If you have a digital satellite receiver, Connect the 3 colour cables to the corresponding colour jacks on VIDEO 2 of your dvd player to corresponding colour jacks on the VIDEO OUT Of your digital satellite receiver...Connect the single stand alone rca cable to MONITOR OUT on your player to the VIDEO IN input of your tv..

OPTION 2 STRAIGHT TO TV: connect the 3 colour cables directly to the corresponding colour jacks on the SIDE of the tv...Connect the single stand alone rca cable to MONITOR OUT on your player to the VIDEO IN input of your tv..

OPTION 3 IF YOUR PLAYER HAS AN OPTICAL INPUT: if this is the case you can just connect a single optical cable to the optical ports on your player and tv and this will enable the sound from your tv to play through your dvd player as well

Check the back and front of your system. The AUX input may be either:
- two red and yellow holes (known as phono L R)
or
-a 'headphone' jack input hole

the cable might not have been supplied with the system. Also, the cable you need may not connect to your iPod through the large connection, it may actually connect through the headphone jack.

So, you may need either:
-a cable with a headphone jack on both ends (one for the system and one for the ipod)
or
-a cable with phono L R on one end (for the system) and headphone jack on the other end(for the ipood)

What kind of input jack for tape and phono?
You could make the right cable from the ipod to the tape input with the right adapters or correct cable. You want to use the tape line level input rather than the phono preamp input. I am assuming you don't need an external preamp for the phono input.
I have seen this unit on EBay with a 1/8 inch plug added as a mod for ipod or other mp3 input. I image they just connect to the tape input leads and drill a hole for the 1/8 input jack. Then you just need a 1/8 inch cable to go from the ipod to the intercom.
There are dealers that can do the upgrade if you don't have the schematics. some of the upgrades are really over the top.
you can get the manual online at PDF heaven.

Yes, you can. You will need a cable like this

that you will plug in the headphones socket on the Ipod and the Line In Audio connections at the back of the Denon.

i am wanting to know the answer to the exact same question. did you ever find the answer?

use your headphone jack, you will need an adapter cable that converts the signal to left / right male RCA jacks. (available at radio shack or on ebay)

these can plug into any red / white inputs EXCEPT phono I use the input labeled CD for my blackberry to listen to MP3's and stream music from Pandora.com

If you dont have an ipod port, then run a 1/8" audio cable from the Headset jack to the Line Input or Aux input of your stereo. If your stereo receiver has Left and Right RCA style connector inputs, you can find simple cheap adapters at Best Buy.
Good luck

The KC-550 is a MONAURAL amp and since the Ipod emits STEREO you have to use a special cable to MIX both the left and right from the Ipod into a single, monaural signal.

You can MAKE a cheapy mixer that will serve your purpose by using a series resistor, say 1K from each of the two Ipod output channels to go to the single mono input to the KC-550.

I would build it this way: Find an old IPOD cable or any 1/8 inch stereo cable and seperate the two wires and the shield. In a 1/4 inch plug, connect the shield from the Ipod cable to the shield (barrel sleeve) of the 1/4 inch plug. Connect one lead of each of TWO 1K resistors to the TIP connection of the 1/4 inch plug. Connect each of the two signal leads from the Ipod to the two remaining floating resistor leads. Insulate the splices.

DON'T forget to put the shell for the 1/4 inch plug over the cable before connecting the cable to the 1/4 inch jack. All parts should be readily available at Radio Shack.

I don't know that I have ever seen a suitable ready made mixer cable for this function.

There should be two RCA input jacks, (L & R), for audio input on the Elan. Use a cable with an 1/8 inch plug on one end that splits to two RCA plugs. Plug the 1/8 plug into the earphones jack and the RCA plugs into the audio input RCA jacks on the Elan. Set the iPod volume low so you won't distort the input signal.

You can do this a couple of ways, depending on the model of iPod.
1. Almost every iPod has an 1/8" earphone jack. Almost every Receiver has RCA input jacks. At Radio Shack, or any store with an electronics section, ask them for an cable with the 1/8" earphone plug on one end and stereo RCA jacks on the other.
Plug the RCA jacks into the receiver, taking note of the name of the input (Aux, iPod, Tape, etc) and plug the other end into the iPod. Set your receiver for the input you're connected to and press Play on your iPod. Enjoy music.
2. From the Apple Store, or any iPod dealer, purchase an iPod Dock for your particular model. Ask the same friendly folks for an audio connection cable and do the same as above for the Receiver end. On the iPod end, just set the iPod into the dock and press Play.
