1. Level
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.
2. 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 3090 will reproduce. Lowering the Low Frequency Cut-Off will limit
the range of frequencies reproduced.
3. Phase
This allows you to optimise the phase of your 3090 to different listening positions
and that of other speaker systems used at the same time.
4. Power Auto/On
If switched to auto, the subwoofer will remain in standby mode until a signal is
detected at the input. The unit will then automatically switch itself on. It will then
automatically return to standby mode if no input signal is present for approximately
5 minutes. With the switch in the 'ON' position the unit remains permanently on as
long as the main power switch is on. The LED positioned on the rear panel indicates
whether the unit is on or in standby mode (red for standby and green when on).
5. Line Input
If your amplification system has a dedicated subwoofer line output it should be
connected here (see fig.1 opposite).
6. Power Switch
Turns the subwoofer on and off.
