CD Player playback education.

[olilugo]

Hi all.
I wanted to start a new thread about getting more educated as to how to properly add a CD-player to your sound system and what to expect.

I don't own any SACD material so maily red-book CD ... I am hoping I am saying right...(regular CD's)

I am only talking about CD-players like Rotel RCD-1072, or Cambridge Audio 840c, possible the new Emotiva ERC-1 etc.

Most of these CD-players have left-right RCA(unbalance) connection, left-right XLR(balance) connection and a coax/optical connection. no mutichannel or hdmi out.

What I undestand so far is these type of CD-palyers can convert , decode and play up to 24bit/384kHz. Some can only go up to 24bit/192kHz.

I also read that if I choose RCA/XLR then the CD-Player will be using their internal DAC and decode and send it to the receiver for the sound to be sent to the speakers.

If I choose optical/coax then the signal goes in PCM and it is the receivers DAC doing the decoding and sending the sound to the speakers. but the max sampling is 48KHz.

1. So if I only have bookshelf spakers + a external Sub, How can I setup my receiver to make sure I am listening using 2.1 since my speakers might not have enough bass.

2. Is one connection more recomended than another RCA/coax/optical. sorry I don't have anything than can handle XLR.

3. Is there any relationship between the number 24bit/384kHz and the numbers I see on a speakers - overall frequency response 50Hz-27KHz

4. If I decided to connect them using RCA, is this the same cable as what people call interconnect. RCA cable that go from the receiver to the external amplifier?

Thanks

in shame ... a bit of a bump.
I was hoping these would have been a few interesing questions...

2. In your case, RCA. Any of the players above will sound better than letting your receiver decode.

3. No.

4. Correct.

1. What kind of receiver and speakers do you have? The crossover point between satellites (your bookshelf speakers) and sub is determined by what you have.

Thanks Danny, Face.
The mains are Rti6.

I know that my receiver has something called pure direct which is for 2ch sound out.

I was hoping to get more information what Analog to Digital Conversion 24bit/384KHz means and how does that translate into sound which somehow works within the speakes frequency response.

Thanks,

384Khz is the sampling rate, how many samples per second. It has nothing to do with frequency response of the speakers.

1. the best set up here would be to run your subwoofer with the speaker level inputs if it has them. this will give you more control over matching the sub with your bookshelf speakers and then it takes out the additional processing that the receiver has to do so you could put it into pure direct mode (wich by its nature is 2 channel only 2.0 and no sub) but that would not matter.
