Chassis material

When delivering powerful, clear sound in professional audio setups, reliability and performance are paramount. The LD System XS 700 PA Power Amplifier offers a robust solution for musicians, DJs, event organizers, and sound engineers who demand consistent, high-quality amplification without compromising on portability or ease of use. Whether you’re powering speakers for a live concert, a corporate event, or a public address system, this amplifier ensures your audio signals are delivered with precision and power, enhancing the overall experience for your audience.

A key challenge with many power amplifiers is balancing output power with sound fidelity and protection against damage. The XS 700 addresses this with its Class D output circuitry, delivering 2 x 350 watts at 4 ohms and 2 x 200 watts at 8 ohms, or a bridged output of 700 watts at 8 ohms. This means you get substantial power output capable of driving a wide range of speakers, whether in stereo or bridged mono configurations, providing flexibility to match your setup’s demands. The Class D design also contributes to high energy efficiency and reduced heat generation, which translates into a lighter, more compact device that won’t overheat during extended use.

Sound quality is uncompromised, with a frequency response spanning 20 Hz to 20 kHz, covering the full audible spectrum for rich bass, clear mids, and crisp highs. The total harmonic distortion is kept below 0.1%, ensuring the sound remains clean and accurate even at high volumes. This level of fidelity is critical for professional applications where audio clarity can make or break a performance. Additionally, the amplifier features multiple gain settings (36 dB, 27 dB, and 31 dB) and input sensitivities tailored to different signal levels, allowing you to optimize volume and tone without distortion.

User protection and system longevity are also prioritized. The XS 700 includes comprehensive protection circuits against DC faults, over-current, short circuits, thermal overload, and features a soft start to prevent power surges. These safeguards ensure the amplifier operates reliably under demanding conditions, reducing the risk of damage to both the amplifier and connected speakers. Controls such as gain adjustment, ground lift to eliminate hum, limiter to prevent clipping, and mode selection offer precise management of your audio signal. Visual indicators for clip, mode, power, protection, and signal status provide real-time feedback for quick troubleshooting during live setups.

In terms of connectivity, the amplifier is equipped with two line inputs featuring both 6.3 mm jack and RCA connectors, allowing seamless integration with various audio sources, from mixers to playback devices. Speaker outputs support both Speakon-compatible and terminal posts, ensuring secure and versatile connections to your loudspeakers. The unit’s low-noise cooling fan maintains optimal operating temperature without introducing distracting noise, which is crucial in quiet environments or recording scenarios.

Physically, the XS 700 is designed with professional use in mind. Its rack-mountable form factor measures 482 mm in width, 44 mm in height, and 244 mm in depth, making it a standard 1U rack unit that fits effortlessly into most audio racks. Weighing only 3.4 kilograms, it is highly portable without sacrificing durability. The amplifier supports both 115 V and 230 V AC operating voltages via a switchable power supply, making it suitable for use worldwide. Despite delivering up to 860 watts at full load, its compact and lightweight design makes transport and installation straightforward.

This amplifier is ideal for a wide range of applications such as live music venues, DJ setups, houses of worship, conference rooms, and outdoor events where reliable, high-power amplification is essential. Its combination of power, sound clarity, protection features, and connectivity options makes it a versatile choice for professionals who need consistent performance in demanding environments.

In summary, the LD System XS 700 PA Power Amplifier offers a compelling mix of power, precision, and protection tailored for professional audio users. Its high output power, low distortion, comprehensive safety features, and flexible connectivity provide confidence that your audio setup will perform flawlessly. Whether you are amplifying vocals, instruments, or playback tracks, the XS 700 ensures your sound is delivered with clarity and strength, making it a trustworthy centerpiece in any professional sound system.
