QUICK STARTBack panels description(1) Mains connectorsThis is the mains input for the NXAMP. There is one mains plug on NXAMP4x1 and twomains plug on NXAMP4x4.• On NXAMP4x1, the plug is a Powercon 20A for the 100 ~ 120 Volts model (ref.NXAMP4x1U) and a standard IEC 3 pin for the 220 Volts model (ref. NXAMP4x1C).• On NXAMP4x4, the plugs are two Powercon 30A for the 100 ~ 120 Volts model (ref.NXAMP4x4U) or the 110 ~ 120 / 220 ~ 240 Volts model (ref. NXAMP4x4W) and twoPowercon 20A for the 220 Volts model (ref. NXAMP4x4C).The amplifier requires high-power so that it can demand high current from the AC service.Connections must be properly rated for reliable operation. See specification part for details.(2) Balanced audio inputs with linkFor each of the four analog audio inputs you will find an XLR3 female input connector, andalso an XLR3 male connector in parallel for sending back the input signal to another unit.4 3 1 2 567PAGE 18 OF 140
