REAR PANEL
9)
Power supply connector :
The base area is the IEC standard, the centre pin is grounded. For
security reasons, it must always be connected.
10 °)
The rear panel has 4 channels. Each channel has an input and an audio output.
11 °) Audio input connector XLR female 3-pin:
These connectors are wired as completely
symmetrical: pin 1: ground, pin 2: hot, Pin 3: COLD. Pin 1 of the two inputs is connected directly to
the chassis and feed the signal processing chains. You can use them with an unbalanced source by
connecting pin 3 to ground lug to the source.
12 °) Audio outputs Connector XLR male 3-pin:
These connectors deliver the balanced outputs
processed signals and they are wired as follows: pin 1: ground, pin 2: hot, Pin 3: COLD. You can use
them with an unbalanced source by connecting pin 3 to ground lug to the source.
Note:
pin 1 of the output is decoupled from the mass for audio frequencies but is grounded to
ensure the rejection of radio frequencies, ensuring electromagnetic compatibility of the processor.
Result:
The amplifier connected to the processor provides grounding the cable shield connected to
their inputs.
Note:
The processor uses a circuit ground loop eliminator. If a parasite snoring occurs in a facility, it is
not due to a ground loop.
During use of the subwoofer (activation of function 6) With Sub), the output of channel 3
is used for the Sub signal (the input 3 is deactivated). For speakers DX12 or DX15, only
input and output of channel 4 are activated.
The main fuse must be replaced only with the same type and value.
