Smart pi NAM

The Smart pi NAM (Network Amplifier Modules) are commercial and industrial amplifiers that can be installed in the field and close to the speaker location, this allows ease of changing audio zoning, sources, priorities and volume for every single speaker within the system.

Indoor and Outdoor (IP66) NAMs are available for each model.

Each NAM has 4 x 12-Watt RMS class D amplifiers, an Ethernet switch with 2 fibre and 2 ethernet ports, and built in DSP (EQ, FIR, delay and gain).

The NAM-HP has 4 x 75-Watt RMS class D amplifiers further offering the ability to incorporate TCoil and induction loops into PA systems for the hearing impaired.
