AT-SSA-3500 DP

AT-SSA-3500 DP: Professional 350-Watt 5-Channel PA Mixer Amplifier with Digital Media Player

The AT-SSA-3500 DP is a robust and feature-rich mixer-amplifier engineered for professional sound reinforcement and public address systems. Designed for reliability and high-output performance, this unit delivers clear, powerful audio suitable for medium to large-sized installations, including auditoriums, commercial buildings, places of worship, and event spaces.

Key Features:-

• High Power Output: 350 Watts RMS nominal power output, suitable for medium to large-scale PA and sound reinforcement.
• Integrated Digital Player (DP): Features a built-in MP3 player module with an LCD screen for media playback via USB drive and SD/MMC card reader.
• Multiple Inputs: Equipped with multiple input channels (typically 5 to 7 Mic/Aux inputs), each with individual volume control for versatile source mixing.
• Flexible Speaker Outputs: Supports multiple output configurations for various PA systems, including low impedance (4Omega, 8Omega) and 70V/100V Line speaker systems.
• AC/DC Operation: Designed for dual power mode, operating on standard AC mains and featuring a provision for 24V or 36V DC (Car Battery) backup for continuous operation during power outages.
• Tone Control: Includes dedicated Bass and Treble rotary controls for adjusting the system’s tonal response, plus a visual graphic equalizer on the front panel.
• System Protection: Features a Resettable Circuit Breaker for protection against overload and short circuits.
• Line Connectivity: Includes Line Output (for Booster Amplifier) and Preamplifier Output (for recording) to integrate with larger or more complex audio setups.
• Box Speaker/Driver Unit Selector: A switch to optimize the amplifier’s output for either general box speakers or high-frequency driver units (which often reduces bass boost for safety).
