DETAILS

The Studiomaster QX2-2000 is an ultra high-power, two-channel digital power amplifier designed for large-scale professional audio systems and demanding rental applications.

The QX2-2000 forms part of the Studiomaster QX Series of advanced digital power amplifiers, featuring intelligent amplifier adjustment technology to deliver over 95% efficiency and extremely stable performance under high current and low impedance conditions. Active power factor correction (PFC) and a highly reliable soft-switching power supply ensure consistent output and dependable operation across a wide range of professional environments.

Despite its exceptional power output, the QX2-2000 is housed in a compact 1U chassis and weighs just 12kg, making it ideal for touring racks, portable systems and fixed installations where space and weight are critical. With universal 90–250VAC operation and support for 2 ohm loads, this amplifier is perfectly suited for high-demand applications such as large subwoofer systems, line array rigs, nightclubs, theatres and rental production systems.

Delivering up to 2 x 1700W at 4 ohms, and a massive 5780W in bridged mode at 4 ohms, the QX2-2000 provides serious headroom and system flexibility. Stereo, parallel and bridge modes, selectable gain settings and a built-in output limiter allow precise system configuration for complex multi-speaker setups.

Performance & Configuration

The QX2-2000 supports stereo, parallel and bridged operating modes, allowing it to adapt to a wide variety of professional sound system designs. Multiple selectable gain settings and an integrated output limiter provide fine control and system protection, ensuring stable operation even at extreme output levels.

With stable 2 ohm performance and an exceptionally high damping factor, the QX2-2000 maintains tight control over loudspeaker drivers, delivering accurate low-frequency response and consistent performance in high-power applications.

Protection, Cooling & Connectivity

Built for professional reliability, the QX2-2000 features comprehensive protection including low voltage, overload, thermal and DC output protection. Variable speed fan cooling ensures efficient thermal management while keeping operational noise to a minimum.

Balanced XLR inputs provide clean integration with professional audio sources, while professional speaker connectors and a 32A mains input make the amplifier suitable for high-current touring and installation systems. Front panel indicators display thermal status, faults and limiter activity for easy system monitoring.
