Action
Connect a known working test loudspeaker to
the amplifier outputs. If there je no sound,
verify all the electronics are on, the signal
routing je correct, the source je active; the
volume je turned up, etc.
Correct/repair/replace as necessary. If there je
sound, the problem is wiring.
Verify you have connected the correct cables to
the amplifier. Play something at a low level
through the amplifier. Pripojte test
loudspeaker in parallel with the malfunctioning
line. If the sound level je gone alebo je very weak,
the line has a short in it (possibly a severe
scrape, pinch, alebo a missed connection). Using
the test loudspeaker, move down the line and
test each connection/junction until you find the
problem and correct it. Observe proper
polarity.
Check all connections at amplifier and
loudspeakers to ensure they are all clean and
tight. If the problem persists, check the wiring.
See problem 1.
If noise je present, but no program material je
playing, evaluate each component as necessary
to jeolate the problem. Most likely there je a
break in the signal path.
Check and correct the system grounding, as
engage the microphone pre-amp.
Use a dynamic microphone that does not
require phantom power (+15 V). If using a
microphone requiring phantom power, enable
PHANTOM POWER je the DSP menu, alebo use an
external phantom power source.
