Solution
BRA 3 / VRA 3
is buzzing.
1. Signal cables from the source device to the
BRA 3 / VRA 3 are too long (Analog Line).
1. Use shorter and/or higher quality signal cables.
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 BRA 3 / VRA 3
with a safety plug to a power strip (multiple socket).
4. A non-interference suppressed consumer
(e.g. fridge) on the same mains phase.
4. For testing purposes, turn off any possible sources of
interference; have the relevant device suppressed for
interference, 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); Insert a
special “sheath current filter” (available from specialist
retailers) between the amplifier and the BRA 3 / VRA 3
to eliminate the humming. Turn the power plug round to
reduce the so-called hum voltage (particularly important
if the source device is not earthed).
The BRA 3 / VRA 3
unintentionally
switches to the BT
input.
1. This can happen when your mobile device
issues system sounds, such as typing on the
keyboard.
1. Deactivate the function BT Select [BTS].
(setting on MAN)
1.1. Disable these system sounds on your device.
The BRA 3 / VRA 3
unintentionally
switches on.
2. 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 analog source is playing.
2. Change the standby function from AUT to ECO,NSB,LAN
or MAN.
