Silly Question Time!

[squidgelet10]

I have powered-up a CD-ROM Drive, removed from a computer, and connected the analogue output to my hi-fi as the CD bit is being awkward about playing copied CD's. This arrangement doesn't appear to work!!!

Can somebody please tell me why?

Cheers.

Where is your power coming from??

[Danny2107]

and how are you going to get the sound to the hi-fi?

[squidgelet10]

Hi Danny2107.

From a comp PSU of course!!!

Cheers.

Basically you cant

[squidgelet10]

The original question was "Why?" though!!

[kempie]

There is no reason why this shouldn't work provided the CD-ROM Drive output line level is within the range of the Hi-Fi input line level.

Typically the CD-ROM should be putting out around 0.7V and the Hi-Fi should be able to cope with 0.3V to 2V.

If the output is too low for the input, a pre-amplifier is required to boost the signal.

Which input are you using on the Hi-Fi?

Hi Kempie.

A sensible answer at last!!!

I am using video/phono auxillary which is where I normally plug in the output from a turntable. The odd thing is that if I plug in a pair of stereo headphones to the miniature stereo jack at the front of the CD-ROM in the comp, I hear sounds. Doing this with the free-standing CD-ROM Drive I am experimenting with does not produce any sounds at all!!!

I would have expected it to work, but as it doesn't, why not use a jack to phono lead from the headphone out socket to the aux in of your hifi?

[kempie]

I presume that you have loaded a music CD and that it is spinning-up OK...

[squidgelet10]

Hi Kempie and Rojash.

Yes, I have loaded a CD: I ain't THAT stupid!

No, I haven't tried connecting a jack-to-phono lead 'cos there ain't any sound comming out when I plug headphones in!!!

Cheers.

P.S. The disk IS spinning.

[ugly_bob]

I might be wrong, but does the CD-drive not need the software from the PC to function?

[squidgelet10]

Hi Ugly Bob!

THAT is what I am trying to find out.

Local expert opinion reckons not!!!

Hey Guys:
Everything O.K. now. The CD-ROM drive I was using was duff!!!!!!! Different one works a treat.

Thanks for your help.

They can sometimes run on their own, depending on the drive itself. Some will not play a CD via analogue outputs on just the software inside.

You can get hi-fi units which read the entire CD off into RAM, and play back digitally from there, resulting in a theoretical silent machine, and error-free playback.

Hi Tomd.

Thanks for that. I am now a very happy chappie 'cos at last I am now able to play all them pirate copy disks as wot I have acquired over the past few months!!!!

Wa-hooooooooooooooooo!!!

Cheers.
