In the search for solutions that simplify sound infrastructures, the MP-124SIP is a Class D digital amplifier that integrates directly into IP telephony environments. By using the SIP protocol, the amplifier is accessible as just another telephone extension on the network, allowing voice announcements to be made directly from any system terminal without the need for additional control equipment.
The compact design of the MP-124SIP is intended for surface mounting, allowing the amplifier to be installed close to the loudspeakers even if the sound source is far away. This leads to significant savings in 100 V line wiring, as the signal travels over the data network until it reaches the amplifier. Such a capability is particularly is particularly useful for systems distributed over large areas, such as beaches, promenades, commercial complexes, or industrial plants. The unit can be placed in surface enclosures near the emission points to provide security announcements or information—such as sea conditions at a beach—simplifying installation in environments where running long stretches of audio cable would be costly or complex.
Regarding amplification capacity, the unit delivers 120 W RMS, providing enough power to drive groups of several horn speakers (e.g., clusters of four 30 W RMS units) or rows of sound projectors, commonly found in streets and industrial zones. Furthermore, its 0 dB (775 mV) line output allows for adding more power if the installation requires it, facilitating the connection to conventional (non-SIP) power amplifiers to increase the number of speakers without complicating the network architecture. The MP-124SIP also includes volume control, LED status indicators, and comprehensive protection circuits, establishing itself as a simple yet highly functional piece of equipment for modern IP public address systems.
