Problem Possible cause Solution

Subwoofer

does not turn

1. The power cable is not connected from the socket to the

subwoofer

Check connection

2. The power has not been turned on Switch to “ON”

3. The switch for automatic switching on is not in the “ON”

position or the “AUTO” or “AUTO HIGH” positions

Check switch setting

4. The subwoofer is not connected with the ampliﬁer (re-

ceiver) through its speaker outlet (High Level) or subwoofer

outlet (cinch) cable

Check connection

5. Defective signal line (cinch) Test with another cinch cable and change cable if necessary

6. The volume of the ampliﬁer has been set too low

Increase volume level to test

7. With a “Dolby Digital” receiver (amplier): the receiver is

not set for subwoofer operation (operating method “Small”

or “ActiveSub = On”)

Check operating mode

8. The outlet level on the ampliﬁer is set too low for the

subwoofer outlet (cinch outlet)

Increase the outlet level of the ampliﬁer

9. The microfuse in the subwoofer has blown (fused) Get a specialist to change the microfuse

Subwoofer

does not

switch off

1. Switch for automatic switching on (Standby) set to “ON” Switch to “Auto” or “OFF”

2. Constant humming at inlet of subwoofer

Use a shorter signal line from the ampliﬁer to the subwoofer or remove any possible sources of

interference (see “Subwoofer hums”)

Subwoofer

hums

1. Signal line from ampliﬁer to subwoofer too long

Use shorter signal line

2. Signal line used is not fault-protected or the protection

has been damaged (defective)

Change signal line for a fault-protected line

3. 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

4. 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 lter” (available from specialist retailers) between the amplier and the subwoofer 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)

Subwoofer

respond to

remote control

1. The battery is ﬂat Change the battery

2. The remote control is not registered on the subwoofer Turn the subwoofer off, wait for 30 seconds then turn it back on. Activate the remote control

and press the “- Phase”, “+ Phase” and “Power/Auto” buttons in quick succession. The sub-

woofer and the remote control are now synchronised
