3. Variable Notch Filter
For details on how to operate the Variable Notch Filter,
see Page 10.
4. Line Level Input
If your amplification system has a dedicated subwoofer it
should be connected to the line level input. If you have a
mono connection from your amplifier you may use either
connection. The output sockets can be used if an
additional subwoofer is to be added to your system.
Note: To prevent damage to the amplifier, only connect
using high level inputs OR line level inputs.
DO NOT USE BOTH METHODS OF CONNECTION AT
THE SAME TIME
5. Volume
This control allows you to adjust the volume of low
frequency output from your subwoofer amplifier to
obtain the best sound/balance within your surroundings.
6. Phase
This allows you to match the time integration of your
subwoofer to the other speakers in your system. This is
especially useful when the subwoofer and any other
speakers in your system are positioned at different
distances from the listener.
7. Frequency
This is used to adjust the point at which the crossover will
separate the low frequencies being used by the
subwoofer from the higher frequencies played by the rest
of the system. Raising the Low Frequency Cut-Off will
increase the frequency range that the MS309W will
reproduce. Lowering the Low Frequency Cut-Off will
limit the range of frequencies reproduced.
8. AC Power Socket
Use this socket to connect to an appropriate mains
socket via the AC Power Cable supplied.
