Hi,
I'm planning to build my own mobile music player for use in my garden or to bring along on holiday. The idea is to use a Raspi 2 with the AMP+ and some 25watt 3-way car speakers. As storage I can use a sd card or, when I'm at home, stream through my music collection using wifi. Besides that it would be realy nice to be able to plug in (a friends) Ipod/Iphone etc throug some kind of line in to be able to play music from there.
Do you know of any possibility to add a line in of some sort? Jack, RCA etc? I did a lot of searching and noticed this (quitte expensive for just a line in) possible sollution: http://www.suptronics.com/Xseries/x300.html
Since this board has an extra set of GIO pins on top, would it be possible to mount the AMP+ to this board and be able to use the line in of the x300?
I really hope you guys can help me out...
Kind regards,
Bram

HiFiBerry team Hi Bram,
for the iPhone/iPad, the easiest way would be also to us WiFi and Airplay (using shairport).
The board you have shown in your link basically is an external USB sound card. A simple external USB sound card might be the easier option here. I can't say if the Amp+ is compatible with this X300 board.

Bram81 Hi Daniel,
Thank you for the quick reply! I'll go and look for an external USB audio card then. Do you happen to know which one is best to use? Can I use the mic in on a for example https://learn.adafruit.com/usb-audio-cards-with-a-raspberry-pi/cm108-type can be used for stereo input or would that be mono?
Best regards,

HiFiBerry team Most microphone inputs are Mono. I can't say about the specific card. Note that cheap cards might limit the sound quality.
I don't have any recommendation for a good USB sound card with the Raspberry Pi. Long time ago I used the Behringer UCA 202. While it works only up to 48kHz, the sound quality is quite good for the price. However, there are lot better cards on the market. But these are much bigger and more expensive.
Is there a reason why you don't want to use Airplay?
Best regards

Bram81 Hi,
I'm not that familiar with Airplay yet, but does that require an internet connection all the time or can I juist connect to the Pi's wifi dongle even when the pi itself it not actualy connected to the internet?
Another question, I've searched the forum to seee wheter it's possible to still use unused GIO pins while the amp+ is mounted on top. I understand that the amp is blocking them all, but not using them all. Could I solder an stackable header to the amp or the pi board to overcome this problem?
Kind regards,

HiFiBerry team Hi Bram,
while you could solder a stackable header, there is the risk that you damage the board when removing the original header. We don't recommend this.

Samuel Darby @Bram81 - it should be possible to use a phone as a wifi access point for the Pi to listen for airplay sources when you are away from a home wifi router. Shairport does not need an internet connection to run.
I'm thinking of seeing if one of the "piface shim" PCBs will help with access to the GPIO/I2C pins so that I can add a display. -
Fishd Hi Daniel,
Following up on this, I'd also be interested in a version with a stackable header to attach LCD displays and give access to a smart power switch.
Any chance you guys would consider this as a manufacturing option? -
HiFiBerry team Hi,
we might think about this in the future. However I can't say if and when we might implement this. Good quality stacking headers are not easy to source.
Best regards
Daniel
