Also I wonder if the PSX is reading the data like a normal CDP or if it's doing DAE.


I have the SCPH 1002 and it has the different sound effects options offered on the TV screen. Not sure how you select these aprt from moving the pointer around the screen, wouldn't want to accidently select if all you had was the controller

Are you saying there IS a lack of detail or not?
Thanks

when we have a cd and it sounds harsch we use roll off with an eq or something.

if the harshness was caused by the tonality a treble roll off can fix it.

if the harshness was caused by distortion or noise adding roll off can`t fix it because we will reach a point we won`t be able to attenuate treble anymore because it will cause lack of detail.

but the ps1 sounds crystal clear with no lack of detail so it isn`t the case.

i hope you understand now.
you see english isn`t my mother language so i did my best.

Hi, could you provide a screen shot if possible? Every model I know that released before the 101 don't have this kind of thing.

Default something wrong

Well tried shorting the (+ve of first cap to -ve of 3rd cap) caps but something wrong. Heavily distorted on both channels.

It's hard to see if traces run underneath the caps. I am right in assuming that the DAC output goes to the +ve (side of the cap with a dark mark) and the 3rd cap is also polarised the same way ?

I appear to be able to measure resistance from the +ve of the 3rd cap to the RCA center !?!?!?!?!?! That would imply the 3rd cap is the wrong way round ? That cannot be ...... I'll retrace my steps

Could it be the opamp not being disconnected?

I think that while making the scheme the first pair of caps was not connected the same polarity as with the A/V MULTI OUT.

One thing you could try would be to remove one of the pairs of caps to disconnect the opamp.

Also, maybe exchanging the place where you wires are connected.

Well, that's the CD player interface that I have on my PSOne SCPH-101. The select button activates a visualization feature instead of stopping the CD.

On the old PSX SCPH-1001, it looks like in the attachement.

The pic. comes form my 15" PC screen with a poor quality composite to VGA adapter.

On mine the DSP buttons are the onces that have a yellow tint. They read 'DOME', 'CATHEDRAL',HALL, STUDIO,DIRECT, and appear to add progressively less echo.

The Q is is DIRECT really DIRECT

Think you are right about the opamp being in circuit. I'll remove the first caps, I now have a small bit for the soldering iron and it's getting easier.

bypass only the first pair of caps and then use the AV /CONNECTOR.
add two female rca from the AV/CONNECTOR outout and you are done forget about the existing rca.
the AV/CONNECTOR out after you bypass the first pair of caps will only have 2 resistors 1k in the signal path no opamps nothing else

Thanks back, but I thought the second set of caps were for AV, while the first and third were for the RCA ?
