How do you control sound?

**UnrealTker** · 12-30-2005, 12:12 AM

I was wondering I see all these projects some with jsut the lcd but other with a HU as well but I was wondering what are people doing to control the volume level. From what ive read most epople generaly dont want to mess with it on thier touchscreen. And if you run the sound through an optical cable you apprently have no sound control until after the signal has been changed back into analoge. Dont mind my stupidity if it seems that way im jsut new to this.

I'm going to use the Control Unit for my Alpine PXA-H701 DSP; it has integrated volume controls.

1) phidget volume knob and my program I made.
2) bass knob of amp

the bass knob is NOT a volume control....lol

as mentioned above, the Alpine PXA-H701 is a great unit....quite a few people on here are using it...

I have wired my steering controls to a keyboard controller which then connect to the PS2 port on my CarPC. I have then mapped the keys in RR to the Volume controls - Works perfectly

I know the bass knob isn't but it gives me more control on the fly of my bass which is nice. Also with my install i don't want a head unit there if I wanted that i would not built a car computer. Thats my thinkin with this sorta thing but the phidget encoder works great for a volume knob if you were wondering....

just to clarify - the alpine that we are talking about is NOT a head unit - it's NOT anywhere as deep as a headunit, and it doesn't play cds in it....

that phidget encoder is pretty sweet! do you have pics of that installed in your link in your sig?

May I ask you how you connect this ?

**RedGTiVR6** · 01-01-2006, 09:12 PM

it has it's own connection....specific plug for the unit...

Basically schematic looks like this:

CarPC -> Alpine PXA-H701 -> Amp -> Speakers

Did I get this right ?
