Hooking Up The Subwoofer
1. Plug the Power Cable to the subwoofer and into the electrical outlet.
2. Turn on the subwoofer – press the POWER switch to ON. The POWER Status LED will be
blinking for a few seconds and should turn on otherwise the subwoofer is working in abnormal
conditions – turn off the subwoofer and check the cables and connections.
3. AUTO POWER switch (selected models) – some models maybe be additionally equipped with
the auto audio signal detection feature.
When the subwoofer is turned on choose one of the two operating modes:
AUTO POWER (ON) – when the POWER switch is in the ON position, the subwoofer will remain
continuously on. The POWER Status LED will remain turned on.
AUTO POWER (AUTO) – when the POWER switch is in the ON position: if no input audio signal
is detected for a some period of time the subwoofer will go into the standby mode (the POWER
Status LED will turn off). If the subwoofer receives the input audio signal it will automatically go out
of the standby mode and will start working (the POWER Status LED will turn on).
Note!
If the input audio signal is too weak, the AUTO POWER (AUTO) mode may not operate
properly - try to increase the subwoofer output level in your audio equipment settings or use the
AUTO POWER (ON) mode.
Note!
The time necessary to turn on and off of the AUTO POWER (AUTO) mode may vary on the
input audio signal strength and the time of the subwoofer’s activity.
4. CROSSOVER regulator (L/R LOW INPUT ONLY) – it allows the adjustment of the low-pass
filter. The adjustment can be smoothly made between the frequencies ranges as marked on
the rear panel below this regulator. After it is set it will determine the highest frequency that the
subwoofer will reproduce.
Adjust the CROSSOVER regulator until the frequency range of the subwoofer blends well with
that of the front speakers. Setting the crossover at the too low level will create a gap between the
frequency response of the front speakers and the subwoofer. Setting the crossover frequency too
high will cause that certain frequencies will be duplicated or offset.
5.PHASE switch – it helps to fully integrate the subwoofer with the rest of your sound system.
When you hear that the subwoofer bass is weak or offset, it may mean that the subwoofer works
out-of-phase – try to change the phase using this switch.
6. VOLUME regulator – you can adjust the sound volume of the subwoofer from minimum (the
knob – max counterclockwise) to maximum (the knob – max clockwise).
Note!
Distortion and sound quality worsening may occur when the knob is in the maximum
position. It may damage the subwoofer. This may void your warranty.
Operation
The HIGH INPUT connectors can accommodate up to 10AWG speaker cables as well as most of
popular plugs (banana etc.). A 10AWG cable is recommended for longer connections (longer than
20 meters / 66 feet). For shorter lengths you can use 12/14 or 18 AWG cables. It is recommended
to leave about 150 cm (5 feet) of extra cable at the subwoofer end to facilitate positioning and
installation of the subwoofer. Do not use staples, nails or other metal objects to secure the cables.
You will get the best sound quality and least amount of hum by keeping the cables away from
other electrical wires and cables.
Note!
Avoid to short-circuit of cables – it can damage this subwoofer or your audio equipment.
This may void your warranty.
Note!
Not all connection cables are provided with this product – refer to the KIT CONTENT.
Please refer to your audio equipment instruction manual for more information.
Your subwoofer is ready for operation.
