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 in a single rack unit. This model, the nXe752BD 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 nXe752, is a 2 channel multi-mode amplifier capable of driving 2 Ohm loads at full power that fits into a 1U sized unit.
