The DSP-E492 adds-on to a 5-channel receiver, a 2 channel receiver, or a separate system by using either a tape loop (line in & rec out) or the pre-amp/amp couplers that are included as a feature on many products.
In your case you would have to use the tape loop. Hook up by following the general rule of "ins" on one piece of equipment go to "outs" on the other piece of equipment.

I think you've answered your own question, circuit power is not going from one side of the DSP chip to the other and that suggests that the DSP's core is at-least partly DOA. You are indeed correct that functional power should be at 3.3V and yes 0.3V does make a difference to the components that rely on a 3.3V feed, however if the DSP is fried you are not going to see normal functionality or be able to diagnose further.

Are you saying the unit dies in 30 seconds at home but it works fine at Radio Shack?

Maybe you need to assess your power sourcing or any other condition that's unique.

Generally speaking, an amp protects 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. Eure 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.

How do I hook up headphones to my Pioneer KRP 500M Plasma TV?

Well if it has a headphone input, then that's simple. However; this still may be possible if you purchase additional equipment. Wireless comes at a heft price, but you can also buy something similar to this item.

Want to use all 5 speakers on surround sound yamaha htr-6230 on tv programs. how set up?

Depends on the audio source for your TV sound. If it's a digital cable box, run a coaxial or optical cable from it to an available digital input, assign it as "TV" and you're done; or if the cable box has 5.1 analog outputs, usethose to the Multi Ch imputs.

If your TV sound source is only RCA cables (stereo) you're stuck with DSP surround modes.

I cannot get the functions on the remote to pbass dsp/eq etc?

The P.BASS function is only available with 2 channel LPCM sources such as mp3,Divx,cd
and wma. Press P.BASS button and "POWER BASS ON" will be displayed on the screen.
The P.bass does not work with DSP/EQ or DOLBY PRO LOGIC ll modes.
If you press P.BASS in the DSP/EQ mode, the DSP/EQ mode is automatically shut off and the P. BASS function comes on.
The DSP/EQ function is only available in STEREO mode.
Press the PL ii mode button to show STEREO on the display.
This feature works with CDs, MP3-CDs, 2 channel DVD-Audio, DivX and Dolby Digital discs.
When playing a DVD disc encoded with two or more channels, multi-channel mode will be selected automatically and DSP/EQ function does not work.

this is something a tech expert on electronics can handle. even replacing parts has to be attended by a pro-technician. something is wrong with your DSP processor or system components. it could be the switch only or it could be the processor.
