HS-PA8108
The HS-PA8108 Network Broadcast Amplifier is a professional IP-based audio amplification solution designed for public address systems, schools, offices, factories, shopping malls, transportation hubs, hotels, and intelligent network broadcasting environments. Featuring a compact 1U aluminum alloy rackmount chassis, the amplifier combines network audio streaming, DSP processing, offline playback, and high-efficiency digital amplification into a single professional device. Designed for modern network audio systems, the HS-PA8108 supports installation anywhere within a LAN or WAN environment using a proprietary network transmission protocol for dynamic audio streaming. The built-in 10/100M RJ45 network interface supports TCP/IP, UDP, and SIP standard communication protocols, enabling seamless integration into IP public address and intercom systems. The amplifier supports playback of background music, emergency paging, alarm signals, and network audio streams, with more than seven levels of intelligent priority management divided into background broadcast, business broadcast, and emergency broadcast categories. Users can also customize terminal priority settings for flexible system management. Equipped with a professional DSP audio processing chip and a 10-band parametric equalizer, the HS-PA8108 delivers high-fidelity CD-quality sound performance. The integrated high-quality decoding chip supports 16-bit MP3/WMA/WAV/PCM audio streams with sampling rates up to 48kHz. For reliable standalone operation, the amplifier includes 4GB built-in storage supporting offline playback and scheduled local program playback, with automatic backup of schedules to an SD card. Additional features include AUX input/output expansion, EMC emergency input, automatic standby energy-saving mode, and multiple protection systems for stable long-term operation. Its built-in 80W high-efficiency digital amplifier supports both 70V/100V constant-voltage output and 4–16Ω constant-resistance output, achieving over 90% power efficiency for commercial audio installations.
