|Problem: I use the JA12 with a generic amplifier and only six speakers are working (half of the dodecahedron).|
The JA12 dodecahedron has two groups of six transducers each (6 Ohm load each), connected, respectively, to the terminals 1+1- and 2+2- of the SpeakOn input connector. Normally the JA12 is powered with two amplification channels separated by means of a cable and 4-channel SpeakOn connector.
Check that you have properly carried out the basic operations by answering the following questions:
a) Was the wiring done correctly?
b) Did you raise both volumes of the amplifier?
c) Did you send the audio signal onto both channels of the amplifier (with an external bridge or internally with a dedicated selector)?
If you answered "yes" to all the questions above, contact our service centre at:
