I have just installed 4 X Up2stream v4 2.0 streaming amps via WiFi and all working fine except there is a reverb on vocals on all media through ceiling speakers(various brands).
When i remove the 2 outside stereo jumpers this reverb disappears but there is static on the speakers.
When I remove the 2 inside jumpers and re-install the outside ones the static is gone but only one speaker working.
How do I get stereo working without the reverb, any ideas?
Thanks.strong text
