Solution
The speaker connec-
ted to the Connect 5.1
is buzzing.
1. The signal cable from the source device to the
analoque input [AUX] of the Connect 5.1 is too
long.
1. Use a shorter and/or higher quality (better shielded) signal
cable.
2. Used signal cable not shielded or the shield on
the cable used is interrupted (defective).
2. Replace the cable with a shielded and/or higher quality
cable.
3. Ground loop (hum loop) “generated”.
A ground loop can occur if at least two
interconnected devices with safety plugs
(e.g. amplifier and computer) are connected to
locally separated power outlets.
3. Connect all devices connected to the Connect 5.1
with a safety plug to a single power strip (multiple socket).
4. You are operating a non-interference suppres-
sed consumer (e.g. fridge) at the mains.
4.1 For testing purposes, turn off any possible sources of
interference; have the relevant device suppressed for interfe-
rence if the humming sound disappears, or initially connect
the source of interference to another mains phase (L1, L2 or
L3) (consult a specialist, if necessary).
4.2 Insert a special “sheath current filter” (available from spe-
cialist retailers) between the sound source and the Connect
5.1 to eliminate the humming.
4.3 Turn the power plug round to reduce the so-called hum
voltage (particularly important if the source device is not
earthed).
The Connect 5.1
unintentionally
switches to the input
[BT].
1. The function BT Select [BTS] is activated and
your (mobile) device plays system sounds, such
as typing on the keyboard.
1. Deactivate the function BT Select [BTS] and set it back on
Manual [MAN].
2. Disable all system sounds on your (mobile) device.
The Connect 5.1
unintentionally
switches on.
1. This can happen when your (mobile) device is
playing system sounds such as when typing on the
keyboard, a digital source is turned on, or an
analogue source is playing.
1. Change the standby function from Auto [AUT] to ECO,
NSB or MAN.
