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. 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 nXp 752, is a 2 channel multi-mode amplifier capable of driving 2 Ohm loads at full power that fits into a 1U sized unit. Another useful feature is that this model offers selectable outputs and Protea™ DSP audio suite software.
