Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.

SOURCE: Onkyo TX-SR705 Muting Problem
if what Dark_Orbit said does not work try doing a master reset by ressing and holding the dvr/vcr button and stand by button simultaneously. This would erase all your assignments so you would need to reassign all your sources hooked up to your onkyo.

It may be your amplifier protection circuitry is being activated and shutting down automatically. This is usually caused by a faulty output transistor in one or more of the channels. I recently repaired my Onkyo TX-SR500 which had this problem.
Using a multimeter on ohms check between C and E on each of the ten output transistors. I found Q6051 and Q6061 to be short cct on all pins. Once you have located the faulty channels check the adjacent components for open or short cct.
I replaced the following components,
R6091 (2.2ohm fusible)
R6081 (2.2ohm fusible)
R6101 2x 0.22ohm 2W
The amplifier now works perfectly, cost of the parts is about $15-$20.
If you don't feel confident doing this yourself just find a friend or tech who can do it for you.
