Hello! I have problem with my STR DB780. There is no sound out from the amp.(All 5 chanels) I have checked for bad conections on the main bord,(Relay,voltreg. IC801.802) I have supply 52 Volt to the end...

Could we back up a bit?

What started this? Did it ever work? Do you know there is a program flowing through the receiver that could be amplified? Try FM. It's internal and so there are no connections to get wrong. What happens with the speaker setup routines?

Staying with FM stereo:

Still no sound at the speakers? Run an audio cable pair from one of the Video 1 or 2 Audio Out pairs to an input on, say, your TV so you can use its speakers as a diagnostic tool. Assumes you know how THAT works.

Anything there?

NO: Then there are no audio signals circulating inside the unit. Give up on the amplifier diagnostics and get into the preamp area.

YES: You have audio inside, just need to get it to the amps. Check for mispositioned Tape switches, Mute button.

Used banana plugs for my amplifier, but bare ends of cable were too long, and then my amplifier short circuited. Silly. I would like to know if the IC is toasted or the power supply (or both). Is this...

If you were playing with the speaker out ----off sure the amp IC is blown or the related circute problem as occured
if you smell the shot circute ...tipically a silicon burn smell....then ...there is a problem in side....
remove the cover and physical check for the blown parts using a tourch if you fing any parts or the bord blackning.........
fault may be there\
some times with a small blown fuse replasement ...cure's it .........

Need to know if we can hook a phantom powered microphone to our shs audio amplifier

Does your microphone have it's own built in phantom power? If it's just a regular mic, you should be able to connect into any MIC inputs on your Amplifier. Otherwise, you'll have to utilize a mic/line mixer to provide the phantom power your mic needs. Then you would connect your mixer to the amplifier.

Which SHS Audio amp do you have? The ones that I am familiar with do not have any MIC inputs.
