Troubleshooting

Always refer any service problems to your Classé dealer. However, if you run into
a problem, we recommend referring to this section first as sometimes an error is
not a malfunctioning product, but simply an oversight in the proper setup of the
component. This section provides suggested solutions to potential problems.
If none of these solutions work, please consult your Classé dealer for assistance.
There are no user-serviceable parts inside the Sigma SSP.
Verify that the power amplifier(s) connected to the SSP is
powered off before checking any cable connections and
before power cycling the unit.
1 Everything appears to be powered on, but there is no sound.
P Adjust the volume control to a moderate level - audible but not
excessive (e.g. -35.0 dB).
P Make sure that the selected source component is powered on,
not in Standby mode, that it is playing an audio track and not in
pause mode.
P Ensure that the proper connector has been selected for the
current source.
P Verify that the Mute control is NOT engaged. This also applies
to sources such as USB connected devices. For example, muting
iTunes will result in no output even though the SSP is setup and
operating properly.
P Ensure that the amplifier is powered up and not in Standby
mode.
P Check the Menu -> Status page to verify an audio signal is being
received.
P Verify that all cables are securely connected to the proper inputs
and outputs, with no kinks or stress points.
2 There is no sound and neither the Standby LED/Status
Indicator nor the touchscreen is lit.
P Ensure that the SSP is properly connected to the electrical outlet
- the AC cord is positioned firmly in the AC mains receptacle in
the rear panel and the power switch is in the ON position.
P If the SSP is properly plugged in and the power from the
electrical outlet is at the proper level, try the following: Put the
SSP in Standby mode, switch off the main power switch on the
rear panel, and unplug the unit for at least thirty seconds. Then
plug the cord back in and try powering up again. Sometimes, a
brown-out (short-term power loss/drop) can activate a protection
mode, which requires a power cycle to reset the SSP to its normal
operating mode.
P Remove the AC cord from the unit, and open the fuse holder
adjacent to the AC cord inlet. If the fuse is blown (best verified
using an ohm meter), contact your qualified Classé dealer.
