Description
The lightweight nXp400 4-Channel Multi-Mode Network Power Amplifier from Ashly features programmable output on each channel selectable via rear panel DIP switches with swept load impedance monitoring. Audio is processed via the 32-bit SHARC DSP at 48 or 96 kHz sample rates and a built-in signal generator is provided for test tone and noise-masking.
The nXp400 amplifier comes pre-installed with Dante network audio module and features aux preamp outputs. Ethernet control is supported via the free Protea NE software (downloadable from Ashly's website) and serial data control is possible via Ashly programmable remotes or third party controllers (available separately). The Protea DSP (Digital Signal Processing) software is included for dynamics, gain, equalization, matrix mixer, crossover, delay, and metering.
The amplifier is suitable for live sound and fixed installation sound systems at performance venues, stadiums, arenas, convention centers as well as schools, store fronts, and places of worship.
