No sound will come out the speakers until amp has sat on for half hour or so. After waiting, I have to flip through sound settings. Usually, the 'unplugged', or 'orchestra' setting will emit sound first. After one of those works, the rest will work.

Sounds like an overheating issue. Check the heatsinks are fixed properly.

Go to settings, General, blue tooth and remove any "other" previous paired BT devices & Turn off BT, then go to Sett. General, scroll down to reset and reset network settings, this will not delete anything. Power off BT speaker. after iPad re-boots turn on BT Speaker First, make sure BT is off on iPad as well as WIFI-wait like 10-15 seconds and then turn BT on in iPad it should see your speaker now and let you pair it up.

first is to hear if sound is there when a DVD etc is connected to one of the rear audio and video inputs on the set.

Also check speakers in the set are in menu switched ON and not OFF.

If a cable box, sat box, receiver are in use check their settings for sound also==not a bad idea to unplug each unit and then after a few minutes plug each back (set , box, etc) to allow each to try to boot up.

Let me know what you find.

The volume setting on the speakers has LITTLE to do with how hard you are driving them. Your source might be extra hot and overdriving them. Read the specs on the speakers and use a sound meter to check your level. The speakers, being only 12 inch, should fill a room 20 foot by 20 foot to about 95 to 100 Db which you are only allowed 2 hours in MAX to prevent hearing loss. At 6 hours you should keep it down to 85 Db SPL. I know several deaf musicians that were exposed to high sound levels in rock bands... a deaf musician is kind of washed up.

To programme a Bose Cinemate remote control for Sky+ & Sky HD

1. Press and hold the Setup button until all 5 green lights show
   

2. Press SAT button
   

3. Using number buttons, enter code 01175. The SAT button should blink.
   

4. Press SAT again. You should now be able to control the Sky box.
   

Note: Use "Exit" for "Backup". Also there is no green button to access the planner on Sky+

I am assuming you are using the standard sonamp 260 not a 260x3
and that when you say you are getting sound on only 1 pair that means only on 1 side (left or right channel only?)

Are using a speaker selector box? you must to regulate the resistance (ohms)

if so first unhook all but on pair of speakers and see if both channels are working.

if they do your problem is in the speaker selector not the amp if no then check to see what the amp level is set to. These are the two small holes on the front right of amp make sure they are set about equal at around half way up.

If that doesn't work flip the RCA cables coming to the amp perhaps you have a bad cable if that doesn't work make sure your receiver (source) is outputing a stereo signal to begin with.

lastly 8 sets of speakers off 1 amp? that's pushing it.even with a high quality Niles or speakercraft selector that controls the resistance going to an amp I wouldn't go past 5 sets.

The right way to do it would be to use 260x3 or a sonance or speakercraft 12 channel amp.

audio board is burnt out and needs replaced. open unit, and trace speaer wires to the small audio bd. remove board, flip over. if burnt, thats the problem. must replace.

be more specific!...how is the tv hooked up? hdmi, component, straight to the tv, or into the amp then tv?....what audio out? optical, digital? also what are you trying to view? local programming? cable/sat? dvd? your best bet is to ignore video on the amp and go straight to tv. can't help u more until i have more specifics.

Go to hardware set up and turn off the hdmi audio output,sounds daft but it should work,also make sure the B speakers are not on as this puts the menu up the left.
hope this helps.

GO TO HARDWARE IN MENU SWITCH HDMI AUDIO OUT OFF, IF THIS DOSE NOT WORK MAKE SURE B SPEAKERS ARE NOT ON AS THIS PUTS THE MENU UP THE LEFT ,SOUNDS DAFT BUT IT DOES.IF YOU STILL HAVE PROBLEMS YOU HAVE A FAULT.
