BEHRINGER is constantly striving to maintain the highest professional standards. As a result of these efforts, modifications may be made from time
to time to existing products without prior notice. Specifications and appearance may differ from those listed or illustrated.
7.5 Bass signal too low
s
Check the EQ settings on your mixing console or on an
external EQ, if applicable.
s
Check the speaker cable pin assignment (see fig. 1.3).
Incorrect pin assignment can cause phase cancellation
and the frequency incursions related to it.
7.6 Poor sound characteristics
s
Check the speaker cable pin assignment (see fig. 1.3).
Incorrect pin assignment can cause phase cancellation
and the frequency incursions related to it.
s
Check if large objects (e.g. effect racks and similar
equipment) are placed in front of the loudspeakers. They
too can negatively influence sound dispersion.
s
Check the sound quality of the input signal by listening to it
on a set of headphones.
s
Also see the instructions in the chapters 7.3, 7.4 and 7.5.
