Clipping with record player only

[toolfan]

Hi, I have some smaller advents paired to a restored pioneer SX780 and with FM radio and Bluetooth it's fine, but when I use the record player if I go past the 10 o'clock setting on the volume, I start getting clipping . I've tried using tape 1 and 2 with player on phono and line and phono setting on the amp both ways too, it doesn't change anything . It sounds great up to the 10 oclock setting . My record player is an audio-technia AT-LP60x. Would an older player be a better match or fix this?
Thanks for any advice

The clipping you're hearing is almost certainly caused by a signal level mismatch rather than a fault with your turntable or amplifier. Here's what's happening: the AT-LP60X has a built-in phono preamp and outputs a line-level signal. The SX-780 also has its own phono preamp built in. When you connect the LP60X to the phono input on the Pioneer, you are running a line-level signal through a second phono stage, which amplifies it far too much - hence the clipping at low volume positions.

The fix is straightforward: connect the AT-LP60X to a line-level input on the SX-780, such as AUX, CD, or Tape. Do not use the phono input. The LP60X has a small switch on its underside or rear that toggles between phono output and line output - make sure this is set to line (sometimes labelled "line" or shown with a symbol). With the turntable outputting line level and connected to a line input on the amp, the levels should match properly and you should be able to use the full range of your volume control.

You do not need a different turntable. An older player without a built-in preamp would connect to the phono input correctly, but the LP60X can work fine with the SX-780 once the signal routing is sorted as above. If you want to use the Pioneer's phono stage instead, you would need to disable the LP60X's internal preamp via that switch, then connect to the phono input.
