4.3 Troubleshooting
No power. First ensure that your Temblor T10 is
plugged in. If it's connected to a power conditioner,
verify that the power conditioner is turned on
and functioning. If it is, yet there is still no power
to the monitor, contact PreSonus for a repair.
No audio. If your Temblor T10 appears to power on but
you hear no sound when playing audio from the mixer
(the lights are on but nobody's home), first make sure
that the cables connecting the mixer to the subwoofer
are working correctly. Also, verify that the Input Gain
control is set to provide enough amplitude for the signal.
Hum. Usually, hum is caused by a ground loop. Verify
that all audio equipment is connected to the same
power source. If you are not using a power conditioner,
we highly recommend that you add one. Not only will
this help to minimize hum, it will better protect your
equipment from power surges, brownouts, etc.
Try setting the Ground Lift switch to "Lift. "
This adds 1 kΩ resistance to the ground of the
balanced inputs and often eliminates hum.
Use balanced cables whenever possible. If your audio
device does not offer a balanced output, you can connect
it to the unbalanced RCA inputs on the Temblor T10, or
you can connect it to a DI (direct-injection) box, which
will provide a ground-lift switch and a balanced output.
Finally, make sure that your audio cables are not
run near power cables, and use cables that are
the appropriate length for your application. Using
cables that are too long not only increases the risk
of noise, it increases the likelihood that the cables
are coiled, which will essentially create an antenna
that picks up all kinds of audio interference.
