Speakers
From amBX wiki
The Philips Pro Gamer and Premium amBX set have a sound system integrated. It's stereo, with two speakers and a sub. A frequency filter splits the high and low tones. It's connected using a stereo jack. The volume knob on the right speaker controls the main Windows volume. So adjusting that will adjust the sound level in all of Windows. A few common questions:

Can I use the amBX to extend my 5.1 to 7.1?
Yes, just connect the stereo jack to your soundcard/mainboard. You will need to connect the sub although it's not used (the low frequencies are sent to the original sub). It's needed to get the sound signal to the speakers. If you don't want this, you could open the sub and do some hacking. Warning: a soldering iron, some wiring and basic experience with those is needed. Do this on your own risk.
Can I use a different soundset?
Yes, just don't connect the stereo jack and use your own soundsystem. You don't have to connect the sub at all this way.
If I use two amBX soundsets, can I use them to create 4.1?
No, since it's a stereo system, you'll get a 4.0 system without a seperate sub. You change this you are willing to do some hacking in the sub. Warning: a soldering iron, some wiring and basic experience with those is needed. Do this on your own risk.
The sound of the amBX set is too loud compared to my other sound devices
Since the amBX set is volume controlled using the main Windows volume, you'll need some extra hardware to adjust this. The easiest solution is using a simple headset extender with build in volume control or a small sound mixer.
My speakers are buzzing
A few options:
- a grounding issue: preferably use a grounded power socket. If one is not available, please don't try to use the heating system or the water supply for this. Turn the power connector 180 degrees in it's socket. This sometimes helps. Otherwise use a grounded multi socket extender which powers all equipment. This even though the extender isn't connected to a powersocket itself.
- some (most likely wireless) equipment is causing interference: try to move all other equipment away from the computer and especially from the amBX cabling.
- the speakers are always on, this can cause some hissing and bussing: lower the volume by using a simple headset extender with build in volume control or a small sound mixer.
