Asystems – NT2504D

The NT series is a range of network-enabled amplifiers designed for installations requiring premium sound quality and high output power.

The NT series network amplifiers offer next-generation D-class amps. The NT2504D is a four-channel amplifier at 250 Watts per channel. NT amplifiers offer a highly efficient power supply that draws less power and produces less heat for saving on energy and air conditioning. Ethernet connectivity ensures complete control of the NT system’s functions regardless of your location, while optional Dante connectivity enables all signals to be routed to remote units with ease.

r2p – Netspire NAM2i

The NetSpire™ NAM2i is an intelligent, network enabled amplifier. The device receives network digital audio and provides output to speakers using two integrated 12 watt Class D amplifiers, digital signal processing, and digital voice announcement.

The NetSpire™ NAM2i devices are housed in IP66 rated enclosures suitable for installation in harsh, outdoor, and rolling stock environments, where immunity from dust, water and physical deformation is required.

The NAM2i units integrate seamlessly with the NetSpire system and allow audio zones to be created anywhere a connection to the network is available. Each speaker is connected to an independent audio channel, and can be assigned to separate announcement zones or grouped in the same zone. The NAM2i can be configured to perform a different series of audio processing functions on each of the output channels. The 24bit DSP can perform the following configurable chains of audio processing functions on each channel:

  • Delay
  • Gain adjustments
  • Dynamic Range Compression & Expansion
  • Power Limiting
  • Parametric Frequency Equalisation

The NAM2i units also have a single balanced audio input which can be used to connect an Ambient Noise Sensing Microphone (ANC). The microphone is used to measure the ambient noise conditions of zone and adjust the volume of announcements automatically to compensate.

The NAM2i housing is IP66 rated, and encompassess the cable terminations on the NAM2i carrier bracket.

Ashly – nXe3.04bd

The nXe3.04bd is a 4 channel multi-mode amplifier capable of driving 2 Ohm loads at full power. The maximum rated output power is 3,000W per channel at Low Z, 2,450W per channel in 70V mode, and 1,250W in 100V mode. There is an automatic but defeatable sleep mode consuming <1W, and instant standby mode controlled by contact closure or software. A switch mode power supply auto-detects 120VAC or 240VAC mains, and a Neutrik® powerCON is used for the AC cord. Each channel has selectable output mode of Low Z, 70V, or 100V, an 80Hz high-pass filter, input limiter, and input gain settings of 26dB, 32dB, 38dB, or 1.4V. Each channel has remote DC level control. Input connectors are Neutrik® XLR/TRS combo jack and Euroblock, while output connectors are Neutrik® speakON. The unit has a front panel power switch and level controls that can be disabled. LEDs indicate Protect, Sleep, Disabled, Com, and Bridge mode status, as well as Temperature, Output Current, Output Signal, and Clipping/Mute status per channel. The unit has Ethernet control with a real-time clock for event scheduling. The unit has serial data remote control, aux preamp outputs, preset control, fault condition logic outputs, optional network audio and AES3 digital audio capability. The amplifier has temperature dependent variable speed forced-air cooling.
