Sub woofer connections

I am considering buying PSW10 sub. What is best way to hook this sub to a Onkyo TXDS 494 surround sound receiver. It appears that there is only one sub out on back . Is this what is referred to a LFE?

LFE stands for Low Frequency Effects. That is what you want to run your cable from the sub out on your AVR to the LFE on the sub.Sunfire TGP, Sunfire Cinema Grand, Sunfire 300~2 (2), Sunfire True Sub (2),Carver ALS Platinum, Carver AL III, TFM-55, C-19, C-9, TX-8, SDA-490t, SDA-390t

I dont think the PSW10 has a lfe connection --- just line in left and right

Just hook the LFE out from your receiver to one of the line in's in the PSW10. The left or right, it doesn't matter -- they are joined internally anyway. Your receiver will route the LFE effect plus any bass below the crossover frequency you define for your speakers to the sub.

Do you have the owners manual? Most of the time it will tell you how to hook up a mono input to the L/R inputs. On my Sunfire it says that if only one signal use the left input. But each is different.
tcrossma might be right that it does not matter which input but I would RTM and be sure. If you don't have the manual call Polk and they can tell you.Sunfire TGP, Sunfire Cinema Grand, Sunfire 300~2 (2), Sunfire True Sub (2),Carver ALS Platinum, Carver AL III, TFM-55, C-19, C-9, TX-8, SDA-490t, SDA-390t -

You're partially correct. You can use either of the L and R inputs alone and the sub will be "fine", but it will play softer than it would if you used a Y-Splitter to both input channels. The reason for this is that both channels are amplified in tandem, and if only one channel gets used, you get less of an input signal. The loss in db from using a splitter (0.5-1db) is far, far less than what you'll lose by only getting one channel's worth of input gain from the sub's input channels.
LFE inputs on subs are unfiltered inputs. That is, they bypass the subwoofer's internal crossover network and feed the sub everything that your AVR (receiver) sends it. That means if your receiver uses a true LFE output, it will send everything from 200 Hz and below. If your receiver uses a more typical subwoofer out channel that is not specifically indicated to be an LFE output, it will use its own internal crossover (usually configurable) to determine the cutoff frequency to the sub.
If your receiver uses an LFE output, then you will be best served by using the L/R inputs via a Y-Splitter, with the splitter being at the sub for minimal signal loss (and minimal hit to the wallet for cables). If your receiver uses a sub out, then use the sub's LFE input and let your receiver control the output frequencies. NOTE: The PSW10 has no LFE input. For $50 more, you get double the wattage, a lower frequency response, and an LFE input in addition to the L/R inputs by purchasing a PSW110 instead.
While the lack of an LFE input isn't significant if you aren't a demanding listener, it is a huge plus depending on the receiver you have. The reason for wanting both inputs is that you have the best of both worlds AND the most options in being able to make your sub blend well with your main speakers.
NOTE: If you use a receiver's "sub out" that has its own crossover and decide to use the L/R inputs for more signal gain, set the receiver's crossover to its maximum, and use your sub's crossover to fine tune the sub's output.
