This organ is used in a large church where the organ and two speakers are separated by approx. 150 ft.
Recently, the left side speaker has quit. However, when the speaker output plugs at the organ are switched, the left side speaker functions, but the right side speaker now does not, which tells us the problem is not with the remote speakers or their built-in amplifiers.
We suspect the preamps at the organ but without a schematic or wiring diagram, we are not sure where to start.
Does anyone have access to a schematic and/or wiring diagram for this model?
Does anyone have a suggestion as to what may be causing this audio failure?
Any suggestions would be greatly appreciated!
