Studiomaster QX4-8000 4-Channel 1U Digital Power Amplifier (4 x 3400W @ 4 Ohms)
DETAILS
The Studiomaster QX4-8000 is a ultra high-power, four-channel digital power amplifier designed for the most demanding large-scale professional audio systems.
The QX4-8000 delivers a massive 4 x 3400 watts into 4 ohms, with the ability to supply up to 4 x 4760 watts at 2 ohms, making it one of the most powerful amplifiers in the QX Series.
This exceptional output capability makes it ideal for driving large line array systems, high-performance subwoofer arrays, and complex multi-speaker PA installations where maximum headroom and system stability are essential.
Despite its enormous power output, the QX4-8000 is housed in a compact 1U rackmount chassis weighing under 12kg, offering an outstanding power-to-weight ratio for touring and portable sound systems where transport efficiency is critical.
Advanced Digital Amplification Technology
Utilising advanced amplifier adjustment technology, the QX4-8000 achieves over 95% efficiency while maintaining stable performance under high current and low impedance conditions. This ensures reliable continuous operation even in the most demanding professional environments, with reduced heat generation and lower power consumption compared to traditional amplifier designs.
As part of the QX Series, the QX4-8000 is designed to integrate seamlessly with both 2-channel and 4-channel models, allowing system designers to scale installations from medium-sized venues to full arena systems using a consistent amplifier platform.
Global Power Supply with Active PFC
The QX4-8000 features an active power factor correction (PFC) system and an ultra-reliable soft-switching power supply, capable of operating universally between 90–250VAC. This makes it perfectly suited for international touring and rental companies, delivering consistent performance regardless of local mains conditions while maximising electrical efficiency.
Built for Continuous Professional Use
Engineered for mission-critical applications, the QX4-8000 includes comprehensive protection systems covering thermal, overload, DC output, and low voltage conditions. Variable speed fan cooling ensures effective thermal management under heavy loads, while thermal, fault, and limiter indicators provide clear real-time system status. The internally modular design allows for fast servicing and long-term reliability in professional environments.
