Description
The nXp Series NXP4002 2-Channel 400W Power Amplifier with Programmable Outputs & ProteaSoftware Suite from Ashly is a Class-D switching amplifier combined with a switch mode power supply. This amplifier meets the requirements of demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces, and convention centers.
This amplifier features the Protea DSP processing for efficient control. The rear panel has DIP switches for programming each channel output for either High-Z or Low-Z operation. This amplifier can be connected to a network with Ethernet control and features serial data control, aux preamp outputs, instant standby mode, preset recall, fault condition logic outputs, and optional network audio and digital audio capability, all controlled using the included Protea Software Suite.
The amplifier offers 32-bit SHARC DSP processing (with 48 & 96 kHz sampling) for comprehensive audio processing and built-in signal generator for test tone and noise-masking. It also offers swept load impedance monitoring on each amplifier channel output.
