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, this version comes from the NXP (networkable + DSP) offerings. This model, the nXp 1504D is a 4 channel nXp amplifier with Ashly’s OPDante® module installed making it capable of transmitting Dante® digital audio from their post-DSP input channel signals.

nXp amplifier inputs are available to the Dante® Controller as individual digital audio sources (transmitters) for use with other Dante® devices. Signals are sampled after the nXp input DSP section but before the routing and matrix mixer section as shown in Protea™ DSP audio suite software. The Protea DSP audio processing suite features the following attributes:

  • Automatic Feedback-suppressor
  • Auto-Mixer
  • Ambient Noise Compensation
  • Dynamics processing with auto-ducker
  • EQ and crossovers including FIR filters
  • Time-alignment and tower delay
  • Variable noise-masking with RTC
  • Swept AC load-analysis with baseline logging

NOTE: Actual product may vary in appearance and specification. For more information on this and other products, please contact your Sales Pro.
