User Manual

1. LINE IN (XLR-JACK combo input)
This is a female combo connector, which accepts an XLR or a JACK plug from almost any type of equipment
with a balanced or unbalanced output. 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 they 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 connected in parallel with the respective line input, so the LINK is wired as the
input. Connect it to the input of another powered speaker to make an array.
3. OUT LEFT (XLR output balanced)
This is a male XLR connector providing a balanced line-level signal. This signal is filtered with a high-pass filter
to connect a satellite 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 connecting a stereo system to a single subwoofer (1 sub +
2 sat). In the case of a 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 connected in parallel with the respective line input, so the LINK is wired as the
input. Connect it to the input of another powered speaker to make an array.
6. OUT RIGHT (XLR output balanced)
Same as above. Use both inputs and outputs when connecting 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 must use the same channel used for
input (left or right).
7. GND LIFT switch
This switch lifts the ground of the balanced audio inputs from the earth-ground of the amplifier. If you have
HUM noise problems on one or more loudspeakers try to change the position of these switches (often all up
or all down for all the units in the system). Please note that to have an effect all cables must be balanced.
