Problem Check the following
No sound The SA750 amplifier is correctly plugged in and switched on
Your audio source is correctly connected, the correct input is selected
and it is not muted
The SA750 is not in protection mode, as described below
Sound cuts-out unexpectedly The SA750 may enter a protection mode if a fault is detected.
The front panel LED will indicate the fault type, according to the list below
FLASHING WHITE: The internal temperature of the unit reached an
unsafe level. Allow the SA750 to cool off
FLASHING RED: The SA750 amplifier detected a speaker short
circuit. Should this happen, please inspect all the speaker cables
to make sure none of them are shorted together. This fault is
very common when bare wires are being used to make speaker
connections
FLASHING ORANGE: The amplifier detected a DC offset.
Following any of the faults described above, the amplifier will turn itself
off and power to the speakers will be removed. To continue using the
SA750, the fault must be removed and the unit must be turned OFF then
back ON
The unit responds erratically or not
at all to the remote control
There are fresh batteries in the remote control
The front panel window is visible and you are pointing the remote
control towards it
The remote is in the correct mode to control the unit i.e by pressing the
AMP button before controlling the SA750.
The front panel display is blank The display hasn’t been turned off. Press the button on the
remote control. See "Display" on page EN-12
Hum on the analog input All cables are making a good connection. If necessary withdraw the
cable from the connector and plug it fully in again (turn the power off
before doing this)
The connections inside the source cable connector are not broken or
badly soldered
If the hum originates only when one particular source component is
connected, that an aerial cable, or dish connection to this source is
ground isolated. Contact your installation contractor
