ENG Problem Subwoofer does not turn on Subwoofer does not switch off Subwoofer hums Possible cause 1. The power cable is not connected from the socket to the subwoofer 2. The power has not been turned on 3. The switch for automatic switching on is not in the "ON" position or the "AUTO" or "AUTO HIGH" positions 4. The subwoofer is not connected with the amplifier (receiver) through its speaker outlet (High Level) or subwoofer outlet (cinch) cable 5. Defective signal line (cinch) 6. The volume of the amplifier has been set too low 7. With a "Dolby Digital" receiver (amplifier): the receiver is not set for subwoofer operation (operating method "Small" or "ActiveSub = On") 8. The outlet level on the amplifier is set too low for the subwoofer outlet (cinch outlet) 9. The microfuse in the subwoofer has blown (fused) 1. Switch for automatic switching on (Standby) set to "ON" 2. Constant humming at inlet of subwoofer 1. Signal line from amplifier to subwoofer too long 2. Signal line used is not fault-protected or the protection has been damaged (defective) 3. Ground loop (ripple pickup) generated 4. Another piece of equipment on the same circuit has no interference suppression (e. g. fridge) Solution Check connection Switch to "ON" Check switch setting Check connection Test with another cinch cable and change cable if necessary Increase volume level to test Check operating mode Increase the outlet level of the amplifier Get a specialist to change the microfuse Switch to "Auto" or "OFF" Use a shorter signal line from the amplifier to the subwoofer or remove any possible sources of interference (see "Subwoofer hums") Use shorter signal line Change signal line for a fault-protected line 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 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 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) 27

Problem
Possible cause
Solution
Subwoofer
does not turn
on
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 (amplifier): 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 filter” (available from specialist retailers) between the amplifier 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)
