Hello.

Since I want to listen to my YDP 162 and my iPad at the same time - using a single pair of headphones - I bought a Y splitter with the following outcome:
- Whenever I use the Y cable the sound of the DP decreases around 30%
- When I turn the iPad on, the sound of the DP decreases another 50% more.
So if I used to set the volume around 30%, now to get the same volume from my DP I need to set it at around 70-80%.
I guess I'm not using the right cable. Is there a nicer solution to my little problem?

Thank you.

The y splitter is to get output from one keyboard and split it to go to two places. You want to get two different outputs and combine (mix) them to one headphones. The volume changes when you connect up in different ways because the cable you are using connects the outputs together in a way they are not designed for.

Try something like this:

(Caveat I have not used this little mixer)

That could work. Note that one wants to be powered by usb, which means another cable. Battery power may be more convenient.

Suppose both YDP162 and iPad have the same output impedance. Using a Y splitter will short-cut these outputs and gives you a signal which is a mean - not a sum - of both signal.

A « mean » means you divide both signal amplitude by 2… and the power by 4 : 25% or -6dB.

If the impedance are different, you have a weighted mean : one signal is divided by less than 2, the other by more than 2.

A powered mixer can amplify the signal which compensate the power reduction.

An alternative would be one of the Behringer Xenyx mixers (the smallest of them is the 502):

https://www.amazon.com/Behringer-502-Premium-5-Input-British/dp/B000J5UEGQ

It has a microphone preamp on one channel, and two stereo input channels, mixed down to stereo output (with separate headphone amp).

. . . channel 1 (mono, with mic preamp if you want it) has a gain control;
. . . channels 2 and 3 have a shared gain control,
. . . channels 4 and 5 have a shared gain control.

I have the next model up (Xenyx 802). The headphone amp is happy driving my AKG K240 phones, which are not very sensitive.

You'll need the appropriate "splitter cables" to get from the stereo output jacks of your signal sources, to the individual R and L jacks (R = channel 2 and 4, L = channel 3 and 5) of the mixer.

It needs an AC outlet for power.

Thank you.
It looks very good, but there's an exportation fee that makes me hesitate.

Don't hesitate to look for used equipment in your local market. There may be bargains.

I got a Shure mixer on Ebay. New $250. Used $45 (including shipping).

Check the Thomann website, it may give you a lower price.
