Question about Sony STRDH710

Open Question

I have the Sony Str-dh710 and a Polk Audio PSW-10. My subwoofer isn't blown and it is on, not hot at all, and my reciever is working perfectly besides the fact that it isn't sending any subwoo

I also pulled off the front grid of the sub and pulled the cable out a bit and it makes a "Humming" noise. It has to be the reciever.

SOURCE: how to hook up a mp3 to a str-dh710

For just listening, anything with a headphone/earbud output can be connected to any available analog Line Level input (except PHONO) with a simple adapter. They don't tell you that in the manual because they want you to purchase expensive accessories like docking stations.

Distance is linear spatial separation of two points. dB is audibility, sound pressure level, volume. The distance setting affects how the various channels are delayed to arrive at the primary listening position at the appropriate time to provide a plausible sound field. Simply making one or more speakers louder or softer will not affect the spatiality of it.

SOURCE: my sony str-dh710 constanstantly goesinto

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Optimum set up for Polk Audio PSW 10?


Run 2 RCA cables from the two Purple connections on your Receiver (Labled "PRE OUT SUBWOOFER") to the Red and White connectors on the back of your Sub (it does not matter which Purple connecter you plug into either the Red and White)

Set the volume control on the Sub to about 75%, and keep the power switch in the "ON AUTO" position. To set the Low Pass value, look at the back of one of the front speakers in your setup, and note its frequency range (will look something like 100Hz - 17kHz). Set the Low Pass at a value slightly higher than the low value on the back of your surround speakers.

To set the phase switch, stand in the middle of the room with some music on (something with some bass, but not over the top bass) and have someone switch between 0 Deg and 180 Deg. Listen for which setting sounds "Louder and Fuller". This is the one you want. You will need to do this each time you move the Sub, as its position may change its phase in relation to the rest of your system.

Good Luck!

PSW 10 Not working


Your 2A 250v slow-blow fuse is blown, located under the back pannel. Mine just did the same thing. Problem is the problem with my PSW10 goes beyond the fuse. I have contacted Polk tech support to help me trouble shoot.
