Product Overview
Ashly's NX Multi-Mode Power Amplifiers are designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers. This model, the nXe754BD comes with the following factory installed digital input options: an Ashly OPDAC4 Internal 4-Channel DAC (Digital to Analog Converter) Option Card and an Ashly OPDante® module that is capable of transmitting Dante® digital audio from their post-DSP input channel signals.
Available in three amplifier series, NX offers 2 or 4-channel models as NX (base model series), NXE (networkable), or NXP (networkable + DSP). This model, the nXe754BD, is a 4 channel multi-mode amplifier capable of driving 2 Ohm loads at full power that fits into a 1U sized unit.
