20 A SERIES MANUAL [ENGLISH] 21A SERIES MANUAL [ENGLISH]
There is a very low level in the bass region:
Check your wiring and cables, particularly unbalanced-to-balanced cables. These
cables should be wired like this:
Unbalanced source XLR Pin
Ground Pin 1 & Pin 3
Signal Pin 2
The most common error is that pin 3 in the XLR is not connected to anything and the
result is a loss of bass.
Acoustical cancellations in the room can reduce bass level significantly, so review the
loudspeaker and listening positions relative to the room walls and adjust positioning
as suggested in section 3.
There is no front panel LED lit up and no audio can be heard:
Check the fuse on the back panel. If it is broken, replace it with EXACTLY the same
type. Contact your nearest service centre if it breaks a second time.
8. SHIPPING
Keep your loudspeaker packaging in case your loudspeakers ever need to be transported.
Without the original packing it is extremely difficult to protect your loudspeakers so that
they can be shipped without damage. ADAM Audio cannot accept responsibility for transit
damages caused by improper packaging.
