SoundCore hums.
Signal lines from source device to
Roth NEO 6.2 SoundCore 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). Plug all devices
connected to the Roth NEO 6.2 SoundCore into a multiple
socket output using safety plugs.
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 Roth NEO 6.2 SoundCore
to eliminate the humming.
• Turn the power plug round to reduce the so-called ripple
voltage (particularly important if the source device is not
earthed).
No playback via
Bluetooth.
There is no connection between the
Roth NEO 6.2 SoundCore and the
mobile device.
Connect your mobile device as described
The mobile device is paired but no
playback takes place.
• The mobile device must be connected again.
• You are out of range.
• Set the volume on the mobile device to maximum.
• Increase the volume of the Roth NEO 6.2 SoundCore.
• Ensure that interference sources like a WLAN router or
laptop are not set up in direct proximity of the Roth NEO
6.2 SoundCore.
• Concurrent operation of WLAN and Bluetooth from a
mobile device is not possible without interferences in
most cases. (Disable WLAN at your mobile device.)
