SW118HA - ACTIVE VERSION INSTRUCTIONS ( FIG. 4 / 5 / 6)
1. INPUT LEFT (combo XLR-JACK input)
This is a female combo connector, which accepts a XLR or a JACK plug from almost any type of equipment with a balanced
or unbalanced line level outputs. The XLR input is wired as follows:
Pin 1 = shield or ground
Pin 2 = + positive or "hot"
Pin 3 = - negative or "cold"
The JACK input is wired as follows:
Tip = + positive or "hot"
Ring = - negative or "cold"
Sleeve = shield or ground
When connecting an unbalanced signal, wire them as follows:
Pin2 / Tip = + positive or "hot"
Pin 1-3 / Sleeve = shield or ground
NOTE: Whenever possible, use always balanced cables. Unbalanced lines may also be used but may result in noise
over long cable runs. In any case, avoid using a balanced cable for one channel and an unbalanced one for the other.
2. LINK LEFT (XLR output balanced)
This is a male XLR connector, it is connected in parallel with the respective line input, so the LINK is wired as the input.
Connect these to the inputs of other powered speakers to make an array.
3. OUT LEFT (XLR output balanced)
This is a male XLR connector, it provides a balanced line-level signal. This signal is filtered with an high-pass filter to
connect a sat speaker. This output is wired as follows:
Pin 1 = shield or ground
Pin 2 = + positive or "hot"
Pin 3 = - negative or "cold"
4. INPUT RIGHT (combo XLR-JACK input)
Same as above. Use both inputs and outputs when connect a stereo system to a single subwoofer (1 sub + 2 sat). In the
case of mono system (1 sub + 1 sat for each channel) you can use left or right input without distinction.
5. LINK RIGHT (XLR output balanced)
This is a male XLR connector, it is connected in parallel with the respective line input, so the LINK is wired as the input.
Connect these to the inputs of other powered speakers to make an array.
6. OUT RIGHT (XLR output balanced)
Same as above. Use both inputs and outputs when connect a stereo sytem to a single subwoofer (1 sub + 2 sat). In the
case of mono system (1 sub + 1 sat for each channel) you have to use the same channel used for input: left or right.
7. GND LIFT switch
This switch lift the ground of the balanced audio inputs from the earth-ground of the amplifier. If you have HUM noise
problem on one or more loudspeaker try to change the position of these switches (often all up or all down for all the
amplifiers in the system). Please note that to have an effect all cables must be balanced.
8. FILTER 80 / 125 Hz switch
Use this switch to set the crossover frequency at 80 Hz or 125 Hz for the internal filter and for the OUT LEFT and RIGHT
connectors. Choose the crossover frequency by your taste or music genre.
9. LEVEL control
Rotary level control: it attenuates the level of the signal sent to the subwoofer speaker. The attenuation ranges from "0"
fully closed (the signal is completely attenuated) to "10" fully open, nominal level (the signal is not attenuated in any way,
so is fed to the internal amplifier at the same level at which it arrives on input).
10. SIGN/CLIP indicator
GREEN LED illuminates to indicate the presence of the signal at the built-in amplifier input.
RED LED illuminates when the internal amplifier's output is limited. When this LED flashes reduce the input signal level.
11. PHASE 0° / 180° switch
This switch reverses the polarity of the subwoofer. Depending on the placement of the subwoofer relative to the full-range
sat speakers, you can get a better low-frequency response in the room if you reverse the polarity of the subwoofer's signal.
Listen in different positions of the venue in order to try which is the best sounding setting.
