Features:
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:
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.
The SMA-4P0808 is a powerful System Amplifier with four analog inputs, two AES3 inputs, two Dante inputs, four outputs (4x800W @ 4 Ohms), 10 PEQ bands per input and output and a frequency range up to 40kHz. The rugged analog input stage accepts input voltages of up to +23dBu thus matching any source on the market today, with an excellent dynamic range of 118dB. Using a switch-mode power supply for clean power supply rails and superior ruggedness, 64-bit digital processing and some of the best converters available on the market today, the SMA-4P0808 offers sound quality that sets standards in professional as well as high-end home audio.
