MX Series — MX36 Operating Instructions Page 11taxConnecting To Your MX36: Analogue Line Inputs and OutputsThe inputs are made via 3-pin XLR connectors, which are electronically balanced and shouldbe connected via a high-grade twin core screened cable, as follows:PIN1: Screen (see note below)PIN2: Hot (signal +)PIN3: Cold (signal -)The unit is designed to operate with fully balanced equipment and ground loops or loss ofperformance may be experienced if connected to unbalanced sources. If it is unavoidablehowever, the following wiring should be used. The cable should still be twin core plus screen.PIN1: Screen - connected to the chassis of the unbalanced equipment - or left disconnectedat the unbalanced end.PIN2: Hot (signal +)PIN3: Cold (ground 0V)NOTE: This unit is wired to the latest industry recommendations. PIN1 is connected directlyto the chassis/mains earth. If ground loops (mains hum) are encountered remove the screenconnection from the other end of the cable and leave it open circuit. If problems persist,consult your dealer/supplier.DO NOT TAMPER WITH OR ALTER ANY GROUND (EARTH) CONNECTIONS INSIDE THE UNIT.Additionally, there is a front panel unbalanced stereo 3.5mm jack socket for connection to aline source (such as a laptop/tablet/mobile phone).1: Screen2: Left3: RightOutputs are also made via 3-pin XLR connectors wired as follows:PIN1: Screen (see note above)PIN2: Hot (signal +)PIN3: Cold (signal -)Note that the rear panel outputs are electronically balanced and so are not galvanically(electrically) isolated. Front panel outputs are transformer balanced and so are isolated.The headphone socket (6.4mm) is stereo, but audio is always mono — do NOT use a mono jackas the output is balanced:1: Screen2: Left (mono)3: Right (mono)
