The Fonestar PROX-240S is a professional-grade PA amplifier designed to deliver exceptional sound reinforcement for a wide range of applications.
- Crystal-Clear Audio: Reproduces sound accurately across a wide frequency range (40 Hz - 20,000 Hz) for natural audio reproduction of both music and speech.
- Minimal Distortion: Maintains pristine audio quality with a low THD+N (Total Harmonic Distortion + Noise) rating of less than 1% at 1 kHz.
- High Signal-to-Noise Ratio: Delivers a clean and clear signal with a high signal-to-noise ratio greater than 77 dB, minimizing unwanted background noise.
- Versatile Connectivity:
- Multiple Microphone Inputs: Equipped with three balanced microphone/line inputs with switchable phantom power (+48V) for both dynamic and condenser microphones.
- Auxiliary Inputs: Features two stereo auxiliary inputs (RCA and Euroblock connectors) for connecting music players, keyboards, or other audio sources.
- Emergency Input: A dedicated emergency input with the highest priority level ensures critical announcements are heard clearly during emergencies.
- Speaker Outputs: Drives both low impedance (4Ω) and high impedance (100V line) speaker setups for flexibility in various installation requirements.
- Comprehensive Controls: Dedicated knobs provide precise control over microphone volume, input selection, master volume, tone control (bass and treble), and more.
- Priority System: Prioritizes microphone and emergency inputs over other audio sources, guaranteeing critical announcements are heard loud and clear.
- Reliable Performance: Built-in safeguards protect the amplifier from overcurrent, DC spikes, and short circuits for long-lasting operation.
- User-Friendly Design: Features intuitive controls and clear indicator lights for easy operation.
- Temperature-Controlled Cooling: The forced ventilation system ensures the amplifier stays cool even during extended use.
