Product Description
The NS-P148 Network Speaker Amplifier is a high-power solution designed for large-scale IP audio and public address systems. Equipped with an industrial dual-core ARM + DSP chipset, it provides stable decoding performance and efficient network audio transmission even under heavy load. As a Network Speaker Amplifier, it is ideal for demanding environments such as transportation hubs, large factories, and expansive commercial facilities.
Offering an impressive 480W output capacity, the NS-P148 supports high-density speaker deployments through 100V line or low-impedance outputs. This powerful pa speaker amplifier ensures wide coverage and strong sound pressure while maintaining low distortion and low noise characteristics. Adjustable bass and treble controls allow fine-tuning for different acoustic environments.
Designed with system reliability in mind, the Network Speaker Amplifier supports SIP protocol and multiple network communication standards, enabling seamless connection to SIP PBX systems and centralized control platforms. Integrated protection circuits and a robust half-rack chassis make it a dependable backbone for mission-critical IP Paging Amplifier and large-scale audio broadcasting systems.
