How to hook up a turntable to a pioneer vsx-1019

any pioneer turntable

According to the specs there aren't any phono inputs which would have their own preamp. Everything else is line level so I'm pretty sure you'll need a preamp either between the turntable and one of the line level inputs or built into the turntable.

You need to have a turntable with a built-in preamp. The receiver does not have a phono preamp in it like the older receivers did.

hold the tune down (-) button and multi zone on/off button for two seconds then receiver should reset on the VSX-1019AHK model!!!

you can "release" the error by pressing the "down arrow" and the "zone 2 on/off" for 2 seconds.

It should work fine. The Pioneer VSX 1019 AH-K has been made so that it can accept 4 HDMI inputs (of which 3 are assignable, and 1 is for the BD player)
If you still have a problem, you can resort to the Official Thread on the Pioneer VSX 1019 AH-K on avsforum. A lot of helpful guys out there, and a very active thread.

The DVI output usually transmits only video (I'm almost 90% sure about this). It would be better if you did not use the DVI to HDMI cable. Receivers and displays can be very picky when it comes to using HDMI. Your Motorola DSR505 has other output options on its rear. I would suggest using the Component out for video (the 3 outputs colored green, blue and red) and either an optical or coaxial for the audio. The Pioneer VSX 1019 AH-K has the required inputs. Of course, you would require new component and coaxial/optical cables to do the job.
Hope this helps. If you're still in a tangle, you can consult the Official Thread on the Pioneer VSX 1019 AH-K on avsforum. There are a lot of helpful people out there.

You need to connect most turntables to a PHONO input or buy a PHONO preamp. Many newer receivers do not have a PHONO input. The AUX port you are using would work fine for a device like a CD player, but turntables need to be amplified. You can buy an external Phono pre-amp from Radio Shack. I don't know anything about this site, but something like this device should work for you. http://www.phonopreamps.com/tc400pp.html
