i am using an ultra stereo js 105-195 processor, i have lost some level (down to apprx.60%)on the centre channel and the dialouge seems spread over left and right, all else seems fine, i am getting some dialouge in my surrounds, but i'm not sure if it's related. although, my monitor says that the centre is pumping out at normal level, i checked the amps and speakers and all seem fine. my local tech suggested i swap the matrix card with the spare, but no change! if anyone has any thoughts on what the problem might be , i would appreciate any posts. p.s i hope this all makes sense, it's gone midnight.

Darryl is on to a possibility. I have had the same thing happen on several Ultra-Stereos, one turned out to be a defective format card, and the others had a bad EQ cards. Since you have a spare processor, use the process of elimination.Let us know what the trouble was when you fix it. Also, "re-seat" the cards.....

To add to Gordon's post about the relays: Yes....they can be a little troublesome. Those were most of the failures I have experienced on the older model EQ cards.Incidently, if you are using 1/4-inch phono plugs from the output of the processor to the input to the power amplifiers, you might want to take a peek at those. If those pulgs are not "exercized" about once every 6 months or so, they could build up a film of oxidation that will prevent a good connection.

Pssst...."phono" plugs are also known as (aka) "RCA" plugs...1/4" plugs are also know as "PHONE" (as in telePHONE) plugs...A minor detail, to be sure.1/4" plugs should have stayed with the telephone switch boards too...the action of plugging and unplugging them kept the contacts clean....I absolutely HATE them for permanent installations. Likwise, use "phono" plugs on your phonograph. Steve ------------------ "Old projectionists never die, they just changeover!"
