Final Words
NOTE
Any form of
tampering with this
product, will void
the warranty.
8. SYMPTOM: NO SOUND FROM THE MAIN SPEAKERS
Probable causes:
Speakon connectors are not connected properly.
Remedy:
Please make sure that the speakon connectors are locked it
tight. Please also note that there are two groups of speakon
connectors (i.e. Group 1 +1, –1, Group 2 +2, –2). Make
sure that your speakers have the multifunction that enable the
connection to the Group 2 for different signal inputs. The
basic connection is on Group 1 (+1, –1).
9. SYMPTOM: SOMETIMES THE SPEAKERS HAVE NO
SOUND.
Probable causes:
When the master volume closes to the maximum level, so the
speaker automatically shut down with no sound. It is because
this speaker has a built-in auto circuit to protect the speaker
when the master volume becomes too high.
Remedy:
Change to a higher power amplifier to work with the
speakers. Please make sure the output power of the amplifier
can match that of the speakers. Another option is to add
more speakers or subwoofers for higher output as below.
1. Add one more loudspeaker DFS-915.
2. Add one more powered subwoofer DFS-118 SUB.
We highly recommend you hiring an audio professional to
advise you on the right engineering for the amplifier and
speakers.
