Have nsx-a505.What is the plug size for the headphone jack?

If your Aiwa does not have an iPod connector (30-pin or Lightning), but has an AUDIO IN jack, you can connect your iPod to that jack from the headphone jack of the iPod using an audio cable with 3.5 mm. plugs at both ends.

When you put your headphones in does it switch off the speakers? If it does it could be a faulty headphone jack.

There are lots of different sized jack plug adapters on the market, you should be able to find one to do the job. I would try Amazon first, they have a good range and decent pictures of products.

The keyboard has a mic jack that is the same size as the headphones. You probably put the headphone plug into the wrong jack is all.

hi there headphone jacks usually only come in 2 sizes, an obviously large one or a small one, (the headphone and the microphone jacks on your computer will be the small ones) if you have a favorite set of phones with a small jack and you need the large one you can buy an adapter that fits the large jack when you plug the small one in. good luck

Headphone jacks are either 1/4" or 1/8". If it's about the size of a pencil, its 1/4". If it's more like the size of your mouse wire, it's 1/8".

There should be a "Demo" button. push it and it should turn off for good. (until the power goes out)

Dear shelnaaqua,
Please connect the headphone to your system and check the sound quality,If it sound good then the connection of the speakers are not ok. This system has HI & low frequency output. Connect woofer to LOW frequency output and tweaters to HI frequency.
please take trouble to vote for me if this solve your problems

There are three sizes of standard headphone plugs:

TRS audio jack: 1/4"
mini: 3.5mm (~1/8")
submini: 2.5mm (~3/32")

According to specs, your RCA system should accept the 3.5mm jack.

Although the manufacturer can pick any option, most large headphones would have the 1/4" and/or 3.5mm jacks. Small earbuds are more often 2.5mm.

RadioShack, or similar store, would have adapters to convert between these sizes.

hopefully u didnt get the male 1/8"-male 1/8" adapter (aka.. headphone-headphone sized jack)

..what u need is the headphone sized jack (that plugs into your ipod) with an end that is RCA stereo (red n white) these go in the back of the stereo...

hook everything up, and voila...

(no need to tell u what u already know, as far as pressin aux.. and all that..)
