Problem Solution
“ON” LED lights
green but no audio
output
Check the wiring and make sure that all cables are working and connected correctly.
Check if you have selected the correct input via the SOURCE switch on the back panel of the
speaker.
Connect an audio source directly to the speaker. If you do hear audio now, the malfunction is in
your signal path.
If the back panel of the speaker is very hot, it may be that the internal thermal protection of the
amplifiers has shut down the audio output to prevent electrical damage. Turn the unit o, let it
cool down and repower.
Hum, buzz and noise Disconnect all signal cables. If the noise is gone, check your audio cables and the equipment in
your signal path.
Check if you have any electrical devices that potentially produce high amounts of RFI (cellpho-
nes, switching power supplies, radio equipment) sitting next to your speakers.
Try to connect the speakers to a dierent power socket.
“OL” LED lights up
constantly
Reduce the input audio level either on the source or with the help of the GAIN control.
“SYNC” LED lights
up but no audio
Check if you have selected the HEDD BRIDGE input via the SOURCE switch on the back panel
of the speaker.
Check if you have routed the audio source correctly to the HEDD BRIDGE output of your
HEDD Bridge extension card.
Speakers vary in
volume
Use the GAIN control to compensate for any level dierences.
