plugging a Cdplayer to Vintage sx-880 Pioneer

i have Pioneer CDL D504 (old laser disc ) as a cd player opinions about this old good player is good sounding piece?
do i need to overhaul or some maintenance ?
i only clean the laser with a Cd lens cleaner
Thanks

After your knowledge and learned understanding cdp & vintage receiver now i m receiving advises for a good matching cdp for my SX-880 Thanks guys

I've run many 70's Pioneer and Yamaha receivers and integrateds with various CD players, never a problem...currently a Pioneer SX-737 (refurbished) with Onkyo C-7030 CD  sounds great...Yamaha CA-810 with same CD,  also great ...

No you will not damage the SX-880 if you don’t crank up the volume control knob to high causing the amplifier to start to distort. If you turn the volume control up to high that will drive the amp into clipping, then you could fry your speakers.

If you read any of the links I provided the common thread is not to turn the volume control up too high which would overload the amplifier and cause it to distort and further increase in the volume clipping.

You can drive any amp into distortion/clipping if you crank the volume up high enough. (Depending on the connected source)

If Al, (almarg), by chance has seen your thread maybe he will take the time to chime in. Al will be able to explain in technical terms in a way the layman can easily understand.

.....dont know the tolerances..,,

final words could the cdp causes some damage to the receiver components we dont the tolerances of the inputs (maximous ) 
Thanks

Let’s work through a real example to make things easier to follow (using data for my Pioneer SX-1250 receiver and Marantz CD-65SE CD player - typical of many vintage amp / modern CD player combinations) :

Input sensitivity of SX-1250 "Aux" (and "Tape") inputs : 150mV
Output voltage from CD-65SE at maximum signal level : 2000mV (2V)
So the CD player output signal is 20 * log(2000 / 150) = +22dB higher than that required for full output power from the SX-1250.

What this means is that the receiver’s full power of 160 watts will be produced with the volume control set to -22dB (referenced to maximum = 0dB). Fortunately, in common with much high-end equipment, the SX-1250 has a volume control marked in -dB, making it easy to see where this occurs.

Perhaps the most "surprising" thing to come out of this calculation is just how little the volume needs to be turned up to get full output : -22dB on the SX-1250 corresponds to somewhere between the 11 and 12 o’clock positions.

• according service manual 

  
  

• input/sensitivity

• phono 2.5mV/50kohms

• AUX  150mV/50kohms
  

• tape play  1 an 2 the same  150mV/50kohms
  

Thanks

Loudness is off
i  ve already had the same services file  from that data base well what i m trying to do now is adjust dc power offset to hjave the same level in each channel because now right channel is louder but the diagram is uncomplete picture and instructios refering some pointed numbers not showed at photo ????? Thanks

i tried both Aux and monitor tape 1 or 2 i dont understand why the monitor tapes inputs sounds better to me and the aux sounds louder but too much mids a highs a little bit exagerated i read many people prefer the monitor over the aux .

Make sure the "Loudness Switch" is in the off position.

People said output of cdp are 2V and input line are 150mv and so .

I believe the "tape in" inputs and "AUX" inputs are 2v

I could not find an owners manual for the SX-880.
Here is the service manual for the SX-880.
Note the #3 Block Diagram.

Claim that for aux is 13X times more and for monitor inputs are only 6X times and these can damage the receiver Thanks

do i need some attenuator because signal ouput from Cd player is higher than the tape inputs

No.

The "tape in" and "AUX" inputs are line level inputs. Just don’t try to use the phono preamp input.

Is there a reason you can not use the AUX input for the CDP?
