Turntable cartridges output a very low level (typically 2 to 5 mV, or 2/1000 to 5/1000 of a volt) and require a special amp to bring the low level signals up to line level (around 0.5 volts to 2 volts), and at the same time perform a special "EQ" on them.
When records are cut, high frequencies are boosted and low frequencies cut so that the maximum amount of information can be pressed into the groove (and also to help deemphasize surface noise on playback)... this is called RIAA equalization. When you playback a record, it requires a reverse RIAA equalization to get back the original signal, as well as a (relatively) large amount of amplification to bring the signal to line level.
So anyway... what you need is called a phono stage or phono preamplifier to hook in between the turntable and the receiver, unless your receiver specifically has a "phono" input on it (in that case, the extra amplification and reverse EQ would be performed by the receiver). Most newer receivers and amps do not have "phono" inputs, because turntables are not in widespread use anymore.
Hope this clears it up...

Also, I JUST used the turntable at home w/ an old amp, and the volume was fine. I only had to have the knob about 1/4 of the way up for good volume. Could I somehow incorporate that old amp into my Onkyo receiver, and use it as a phono stage?
What you could do would be to run the turntable to the old amp, and the "record out" (for tape recording, if the amp has one) to one of the Onkyo receiver's inputs -- or to your Meta42. Otherwise you'd either have to just use the old amp, or buy a separate phono stage. It might be a good idea to just get a separate phono stage so you don't waste power running both the old amp and the receiver at the same time.
