Troubleshooting
Here is an overview of the most common problems. If you have any further questions please contact your Spectral dealer.
Problem
Possible cause
Solution
SCA3 system does not
turn on
The power cable is not connected from the socket to the SCA3 system
Check connection
The power has not been turned on
Switch to “ON”
Sound reproduction too soft
Volume of SCA3 system set too low
Increase the volume using the volume control. Increase the volume of the source device.
SCA3 system does not
respond to remote control
The battery is flat
Change the battery, observe correct polarity at insertion.
No sound
reproduction
Sound format of the source device wrongly selected (Digital input „AUX“)
Please check the correct setting of your source device (see Page 34).
„DTS“ or „Dolby Digital“ coded output formats cannot be reproduced
Source device not producing any signal
Digital output on the source device not activated (please refer to device instructions)
Cable not correctly connected / faulty cable
Check the connection of the source device to the SCA3 and change the cable where necessary
SCA3-system hums
Signal line from amplifier to SCA3-system too long
Use shorter signal line
Signal line used is not fault-protected or the protection has been damaged (defective)
Change signal line for a fault-protected line
Ground loop (ripple pickup) generated
A ground loop can be generated when two or more devices connected via a signal line (cinch) are plugged
into separate sockets (e. g. amplifier and computer). All devices connected to the amplifier should be
plugged into the same multiple socket outlet
Another piece of equipment on the same circuit has no interference suppression
(e. g. fridge)
Switch off possible sources of interference to test; unplug the device concerned to see if the humming noise
disappears or connect the source of interference to a different circuit (L1, L2 or L3). (Where necessary take
advice from your electrician.) Insert a special “ferrite common mode filter” (available from specialist retailers)
between the amplifier and the SCA3-system to eliminate the humming Disconnect and rotate the mains
plug to reduce the so-called ripple voltage. (Particularly important if the amplifier is not earthed)
No playback via
Bluetooth.
There is no connection between the SCA3 System and the mobile end device.
Connect your mobile end device as described.
You are outside of the range.
The mobile end device is paired but no playback takes place.
Reduce the distance to the unit to less than 10 m.
The mobile end device must be connected again.
You are out of range.
Set the volume on the mobile end device to maximum.
Increase the volume of the SCA3 System.
Ensure that interference sources like a WLAN router or laptop are not set up in direct proximity of the SCA3
System.
Concurrent operation of WLAN and Bluetooth from a mobile end device is not possible without interferen-
ces in most cases. (Disable WLAN at your mobile device.)
