4.1 Troubleshooting
No power. First ensure that your Sceptre S6/S8 is
plugged in. If it’s connected to a power conditioner,
verify that the power conditioner is turned on
and functioning. If so, yet there is still no power
to the monitor, contact PreSonus for a repair.
No audio. If your Sceptre S6/S8 appears to power on but
you hear no sound when playing audio from the source
signal (the lights are on but nobody’s home), first make
sure that the cable connecting the source signal to the
monitor is 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.
Use balanced cables whenever possible. If your audio
device does not offer a balanced output, 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.
