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.
