LD Systems XS700 Class D Professional Power Amplifier | 2 × 350W @ 4Ω | 700W Bridged | 1U Rackmount PA Amplifier LD Systems XS700 – Compact Class D Power Amplifier for Professional PA Systems Powerful Performance in an Ultra-Compact Design The LD Systems XS700 is a professional two-channel Class D power amplifier designed to deliver impressive output power while maintaining an extremely compact and lightweight form factor. Built for musicians, DJs, rental companies, houses of worship, commercial installations, conference facilities, and professional audio integrators, the XS700 provides reliable amplification without occupying valuable rack space. Thanks to its 1U rackmount design and weight of only 3.4 kg , the XS700 is an excellent solution for portable sound systems as well as permanent installations where space, efficiency, and reliability are essential. Despite its compact dimensions, it delivers enough power to drive a wide variety of passive loudspeakers with confidence. Whether you’re powering full-range PA speakers, stage monitors, installation loudspeakers, or distributed audio systems, the XS700 offers clean amplification with the dependability expected from professional audio equipment. High-Efficiency Class D Amplification At the heart of the XS700 is a modern Class D amplifier architecture , designed to maximize efficiency while minimizing weight, heat generation, and power consumption. Unlike traditional analog amplifiers that generate significant heat, Class D technology converts electrical energy into audio power much more efficiently. This allows the XS700 to deliver substantial output while remaining compact and lightweight. Benefits of the Class D design include: Higher energy efficiency Lower operating temperatures Reduced power consumption Lightweight construction Excellent reliability Smaller rack footprint For mobile sound companies and installers alike, this translates into easier transportation, reduced cooling requirements, and lower long-term operating costs. Professional Power Output The XS700 delivers the ideal balance between power and portability. Output ratings include: 2 × 350 Watts @ 4 Ohms 2 × 200 Watts @ 8 Ohms 700 Watts Bridged @ 8 Ohms This versatile output configuration allows the amplifier to power a wide range of professional passive loudspeakers, from compact installation speakers to larger full-range PA cabinets. Whether operating in stereo for left/right systems or in bridged mode for higher power applications, the XS700 delivers clean and consistent performance suitable for demanding professional environments. Flexible Operating Modes One of the strengths of the XS700 is its ability to adapt to different system configurations. The amplifier supports three operating modes: Stereo Mode Ideal for traditional left/right PA systems where each amplifier channel powers an individual loudspeaker. Parallel Mode Allows a single input signal to feed both amplifier channels simultaneously, simplifying installations that require identical program material on both outputs. Bridge Mode Combines both amplifier channels into a single high-power output capable of delivering up to 700 Watts at 8 Ohms , making it suitable for larger passive loudspeakers or subwoofer applications. This flexibility makes the XS700 equally useful for portable PA systems and permanent commercial installations. Professional Connectivity The LD Systems XS700 provides comprehensive input and output options for seamless integration into virtually any professional sound system. Inputs Balanced XLR Balanced 6.35 mm TRS Jack Unbalanced RCA These options allow compatibility with professional mixing consoles, digital mixers, DSP processors, audio matrices, media players, and consumer audio devices. Speaker Outputs The amplifier features professional speaker outputs including: Speakon-compatible connectors Binding post terminals These industry-standard connections ensure secure speaker wiring for both portable and installed sound systems. Intelligent Protection Circuitry Professional amplifiers must perform reliably under challenging conditions. The XS700 incorporates multiple protection systems designed to maximize reliability and protect both the amplifier and connected loudspeakers. Protection features include: Short-circuit protection DC protection Thermal overload protection Over-current protection Soft-start circuitry Integrated limiter These systems continuously monitor amplifier operation and respond automatically whenever abnormal conditions are detected. The result is greater reliability, longer component life, and increased confidence during live performances and permanent operation. Optimized Cooling System The XS700 uses a low-noise forced-air cooling system to maintain stable operating temperatures during extended use. Efficient airflow ensures consistent performance even when operating at higher output levels for long periods. The cooling design balances effective heat dissipation with quiet opera
