Might sound like a wierd question but what can those digital I/O be used for? Is it so you can sample your laptop straight throught the headphone jack?

1/4 digital connections on mpc2kxl, I don't think they ever got them to work correctly.


Then there is history being made in my very bedroom... lol

My 1/4" jack digitals i/o are working perfectly. I got the input hooked up to my M-Audio 2496 SP/DIF out 24/7 with a regular rca-rca cable I found in my cable box, and a rca-jack converter plug on the MPC side.

Its great, ZE-RO noise, so you can effectively use the treshold thingy.

SP/DIF is plain coaxial, meaning that it will work with any rca-rca (or jack-jack, rca-jack or fricken xlr-speakon if thats your set-up). Read the article on coaxial SP/DIF, and youll understand (I read the dutch one tho, so I dont know how good the english one is. I suppose better really.)

I have wondered this too. What benefits/purposes are there for using the digital ins and outs? Is it just better quality connection or is some other type of info transferred? Since you got them hooked up and using them, please let us know.

hahaha sh-t youre right.

anyways,

any standard 75 Ω A/V cable can be used for coaxial connectivity

http://en.wikipedia.org/wiki/S/PDIF

definition of coaxial cable:

Coaxial cable, as a common example, has a wire conductor in the center a circumferential outer conductor and an insulating medium called the dielectric separating these two conductors. The outer conductor is usually sheathed in a protective PVC outer jacket.

http://en.wikipedia.org/wiki/Coaxial

Bottom line is, coaxial S/PDIF can be connected to any connector with two or more connection points. It just doesnt matter whether its a TS jack or an RCA. In fact, I find it rather strange that RCA is the standard for S/PDIF (because that is what it is) because a TS jack would have the same functionality, but would be much more durable.

Yeah its definitely better quality, but what do you mean with 'another type of into'?


Digital audio pros and cons

Good:
- No noise, no buzzing, just pure clean signal :D
- Cable isnt prone to ground loops, magnetic field or anything that might f--k up the signal.

Not good:
- Not every piece of gear has S/PDIF I/O
- You can't use the Rec Gain knob anymore. I dont know if you can set the digital gain on the 2000xl somewhere, but to reach a proper 0dB max, I just tweak the S/PDIF out on my soundcard.

Conclusion:
I prefer S/PDIF over analog. Simple.

Thats not right, coaxial cable is still prone to emf and noise, however, less so than standard audio cable. :P

Your digital device will send sound out at 24-bit/44.1kHz over s/pdif.......Im assuming w/ the digital i/o on the 8-outs will allow you to sample at this rate as well??

I was hooking my 2000XL to my mbox via the the spidf dig. out and never had good results with it although I have messed with lots of different settings.

Here`s the link to the thread that lampdog was talking about, it could be helpful:

Here's my knowledge on the matter: The difference between the two types of connections are: one is digital information and one is an audio signal.
Audio=electric current running through a wire.
Digital=a digital signal telling the computer what the soundwave looks like by describing it with a binary on/off message (1 or 0).
Your laptop headphone out is an audio out so connecting it to the digital in on your MPc would not work. You would want to connect to the digital ins and outs on your MPC to the ones on your audio interface for example. The purpose of the digital ins and outs is for two pieces of gear with digital ins and outs to communicate without having to record an audio signal and convert it(your soundcard and its drivers do this) and therefore there is no chance for a loss of quality (i.e. your 10cent radio shack audio cable from 1952 with no shielding can add distortion).

I agree RCA sucks it's not even grounded like a 1/4" or XLR which are the standards in most pro studios that I've been in. Lots of room for noise to be picked up. Numark makes turntables with digital outs for noiseless (less noise) sampling (the needle can still run over a dust bunny etc).
