I just connected a cable to the RCA input jacks on my alpine so I can direct connect my iPod. Once I remembered how to turn the auxilary inputs on, I found that it produced a steady volume output that I cannot change using the alpine volume control, nor the iPod volume control. the connection cable for the iPod has the left and right RCA jack's on the end for connection to the stereo and the iPod dock connector on the iPod end, so I am NOT plugged into the iPod via the headphone jack. Is there a way to change the output volume level when your input is received via the aux input jacks? Also, if I leave the iPod playing and change source back to the radio, I can still hear my iPod playing in the background. Is this normal? I would assume that I would only hear the aux item when I have the source switched to AUX.
Your problem stems from the fact that the CDA-7892 is not equipped with an RCA aux-input jack. If you're plugged into RCA connectors at the back of the head unit, they're outputs, not inputs. The sound you hear is just feeding back through the outputs and into the head unit's amplifier. If you want to play your iPod through this head unit, you need to purchase either the auxiliary input adapter (KCA-121B) or iPod adapter (KCA-420i).
This is a easy one. You're not tapped into input jacks, those are output jacks for a external amp. If you're adept at soldering its possible to interrupt the stereo L&R that is fed to the volume control on the head unit (with a double throw switch for example, or the interrupt contacts on a female mini stereo plug) and let the iPod feed into that point.. The head unit tone and volume controls should work just as though the audio was coming from the head unit tuner. Sometimes tone controls are wired ahead of the volume control so the proper place to interrupt and inject audio would then be into the input of the tone controls rather than into the volume control wired downstream.
Yeah, I did that too, thinking the rca jacks in the back of the deck would work. However, I did purchase the "aio-net" adapter from best buy (not alpine, but an aftermarket) and connected my dvd player to the rca jacks. I am having the same problem as I did before--no volume control at the deck. any ideas? I tried to change all the settings on the deck. The deck recognizes the "aux" device and the sound comes through the deck, but at a much too low volume. anyone?? anyone at all?
