Purchased stanton T.52 Turntable. hooked it up to stereo but volume is very very low. cannot find line / phono switch if there is one on this model.

so you have a pre-amp otherwise you aint trying to use otherbinputs
, but the ground cable goes with your sungle phono soursce to the PHONO-preamp and the output is a Line-level , which you should here

If your unit doesn't have a PHONO connection you will have to get a Phono Preamp to connect between the TT and any Line Level input, like Aux.

eBay always has some... http://shop.ebay.com/?_from=R40&_trksid=p3984.m570.l1311&_nkw=phono+preamp&_sacat=See-All-Categories

Google "Stanton T.60 Turntable cartridge" and sift through the multitude of offerings.

For example:

Have a look on the back input panel of the sc-dv290. Check for a "PHONO" input. If there is no phono input it will not play turntable. If there is: then plug it the turntable in and switch the SC-DV290 to PHONO mode.
Another way would be to purchase a "phono preamplifier" from ebay: Hook the turntable into the phono preamplifier, and the preamplifer into the SC-DV290 AUX input.

You need to make sure that you plug it into the receiver with PHONO input.
New receivers today does not have PHONO stage so the sound will be very very low and not listenable at all.

what model is your receiver?

Try the switch in the other position and see if that fixes the problem. some turntables had a phono level that is different than a standard rca line level input. Also try a different cable if the rca is not hardwired in to the turntable. The cable could be bad. If worse comes to worse upgrade to another amplifier or tuner that has a separate phono input. hope that helps.

Is this a sudden onset problem or has it always been like this?

A traditional turntable requires a Phono preamp inline with it to PRE amplify and frequency-balance the minute signal produced by it's cartridge for later amplification by a power amp. Most stereo receivers and preamps have Phono connections and internal preamplification strictly for that purpose. Recent AV Receivers generally do not.

You don't say what electronics you're running this through. I suspect you have it jacked into a Line Level input instead of a specific Phono input. The result would be very low, tinny sound.

If so, you need to get a Phono Preamplifier.

Make sure it's plugged into the PHONO section. There's a good reason they label it for that - only Phono requires PRE-amplification to boost the tiny signal from the cartridge to a suitable level for the following stages to use.

You can use either type of input but you have to tell the Stanton which one.

I hope you realize that "Phono" isn't just a generic connection with a different name. It actually goes to a preamplifier (either in the Stanton or in your receiver) that not only raises the level of the signal but radically modifies its frequency respone via the RIAA curve (look it up) to make it normal.

A normal turntable without internal electronics would not have the LINE option.

1) There is a switch marked PHONO/LINE on the rear apron.

2) Select PH if you're connected to PHONO on your receiver or select LINE if you're connecting to a line level (non-phono) input, say, a soundcard or a standalone amplifier without a a phono section.

You have a VERY nice turntable! TWO quick questions: 1) How do you define "minimal" volume? It is not NECESSARILY unusual that your turntable / receiver combination will have lower volume than your tuner, CD or DVD player. What happens when you CRANK IT UP?! Don't worry about the position of the volume control! 2)Are you changing the turntables output settings via the switch under the platter? Please post a reply and we'll go to the next step! Note: Ceramic cartridges are pretty much extinct. They were strictly low-end, low-cost, low-fidelity devices used in cheap audio systems of "yesteryear". Have you ever seen a BSR or Garrard turntable? Or your grandad's Magnavox Console Stereo? THAT'S where you'd find a ceramic cartridge!
