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 4070 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 4070 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).
