NEXO NXAMP 4X1 Owner's Manual - Yamaha Commercial Audio

NXAMP4X1 VERSUS NX242: WHAT’S NEW ?Computing resourcesThe DSP resources have been multiply by 3.5 between the NX242ES4 and the NXAMP4x1(so it means by 7 between the NX242 and the NXAMP4x1). This will ensure that theNXAMP4x1 will have enough DSP resources to deal with many years of algorithmimprovements. Other key components like CPU speed, memory quantities and so on havebeen also upgraded.Four separate inputsThe analog input stage now offers 4 separate symmetrical inputs, each on XLR with link(due to the 3U height of the unit, there is plenty of space for connectors at the back, aswell as space for air cooling inside the rack itself). All the inputs offer a considerable 28 dBuheadroom (same than on the NX242). These analog inputs leads to last generation 24 bitsconverters running at 48 KHz (like on the NX242-ES4).Power supplyThe NXAMP Powered TDcontroller uses three separate switch mode power supplies (SMPS).A first small power supply is used for powering the TDcontroller digital board, and to initiatethe power amp. The two other big power supplies are used for power amplifier channels 1& 2 (on one power supply) and for channel 3 and 4 (on the other one). The two largepower supplies are precisely tailored to work around a precise Mains voltage, so separatemodel of NXAMP4x1 exists for 100 ~ 120 Volts on one side (this is model NXAMP4x1U),and for 220 ~ 240 Volts on the other side (this is model NXAMP4x1C).Ethersound optional boardThe NXAMP4x1 is designed to accept the optional NXES104 board witch offers four digitalinputs among a bidirectional 2x 64 channels Ethersound ES100 network. This optionalboard uses the new NEXO slot which prevents the necessity to open the top panel of theamplifier for installing the board. NXAMP4x1 firmware upgrade can also be performedthrough this Ethersound port.User interfaceThe front panel LCD display is now a comfortable 2 x 40 characters display, for easy accessto the parameters for each channel.PAGE 11 OF 80
