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

GENERAL DESCRIPTIONDSP).All signals, audio or sense, use 24 bits converters. The CPU can also set up the analoginput and output gain for each channel, thus ensuring that the dynamic range of thesystem is always optimized (regarding volume, gain, patch and bridge settings).Monitoring of the amplifier modules and power supplies (including multiple measurementsuch as temperature, voltages, current, integrate current, …) are done both by the CPUand the DSPs.Power amplifier blocksThe power amplifier part is a custom design to fit the very unique concept of digitalprotection of an analog amplifier. On the pure amplification side, it utilizes customtransistor (thin chip and small thermal resistance), and the well known Yamaha EEEnginetechnology, that offers the sonic quality of the conventional class AB amplifier with theefficiency of the class D. You can learn more about the EEEngine technology at thefollowing address:http://www.yamahaproaudio.com/topics/leading_technology/learn_more_about_eeengine/index.htmlPower outputs blockThe power outputs block is used for current and voltage sensing at the output of the amplifier. Thesedatas will be used by the DSP for protecting both the amplifier and the NEXO loudspeaker connected.This stage features also a programmable routing unit that allows using the amplifier in bridge modeon the same speakon pins than in non bridge mode.When using the NXAMP4x1 Powered TDcontroller in four channels mode, here is the output routing:PAGE 26 OF 80
