I wonder if anyone can help : my friend owns a restaurant has been left high and dry by an av company who went bust in the middle of a job and he has no money to pay anyone else. There are 8 JBL ceiling speakers fitted plastered in and cables running to behind bar area, they have used regular 42 strand speaker cable for each speaker . The speakers are 8 ohm 80w rated. luckily they left the amp a Teac AR610 with 130w per ch output at 8ohm or 100w per ch at 4 ohm. each speaker is in a different section of the restaurant so Ideally i'd like to run them in mono so that theres no sound separation in that area. Can I bridge the output from the AR610 to mono at the amp and connect amp to some sort of connector then each speaker to that connector.? also can I put an in line volume control to each speaker? obviously I'm concered with potential impedence problemd and damage to amp etc Any help would be appreciated. Thanks!
