The Multi-Purpose Mixer Power Amplifier is a cost-effective and high-performance solution designed for a wide range of public address (PA) applications. Engineered with maximum versatility in mind, this unit is ideal for schools, offices, places of worship, and medium-sized environments where clarity, reliability, and simple operation are essential.
With multiple power output options, the amplifier ensures flexibility for different setups. In addition, its paging function and dual-zone coverage provide tailored sound distribution, making it suitable for both announcements and background music. Therefore, it is a reliable choice for facilities that require effective communication and sound reinforcement.
The user-friendly front panel allows easy operation, even for non-technical users. Furthermore, the amplifier includes two electronically balanced microphone inputs for clear speech delivery and two AUX inputs for connecting external audio sources such as players or media devices. A recording output is also provided for added functionality.
To enhance sound quality, the unit supports phantom power on MIC 1, ensuring compatibility with condenser microphones. Moreover, the wide tone-control adjustment range of ±10 dB for both bass and treble allows fine-tuning of audio output. As a result, users can enjoy crisp highs and deep lows tailored to their environment.
For flexible speaker connections, the amplifier provides 70V / 25V line outputs or 4Ω speaker outputs, ensuring compatibility with various speaker systems. Built with durability and efficiency, this mixer power amplifier is designed for long-term use while maintaining consistent performance.
