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 operation, making the amplifier suitable for:

• Conference rooms
• Houses of worship
• Hotels
• Theaters
• Educational facilities
• Live performance venues

---

Compact 1U Rackmount Design

Rack space is valuable in professional audio installations.

The XS700 occupies only 1U while providing power levels typically associated with much larger amplifiers.

Its compact dimensions allow installers to maximize rack capacity while reducing overall system weight.

The amplifier is particularly attractive for:

• Portable racks
• Touring systems
• Mobile DJs
• Rental companies
• Commercial AV racks
• Equipment cabinets
