DETAILS

The Studiomaster QX2-3000 is a high-output, two-channel digital power amplifier designed for large-scale professional sound systems and heavy-duty rental applications.

The QX2-3000 forms part of the Studiomaster QX Series of advanced digital power amplifiers, utilising intelligent amplifier adjustment technology to deliver over 95% efficiency and stable performance under high current, 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 extremely high power capability, the QX2-3000 is housed in a compact 1U chassis and weighs under 12kg, making it well suited to touring racks, portable PA systems and fixed installations where rack space and weight are critical. Universal 90–250VAC operation and stable 2 ohm performance make this amplifier ideal for driving large subwoofer systems, line arrays, club systems, theatres and high-power rental rigs.

Delivering up to 2 x 2550W at 4 ohms, and an enormous 7140W in bridged mode at 4 ohms, the QX2-3000 provides exceptional headroom and system flexibility for the most demanding professional audio applications.

System Performance & Power Handling

The QX2-3000 offers stereo, parallel and bridged operating modes, allowing it to adapt easily to a wide range of system designs. Multiple selectable gain settings and a built-in output limiter provide precise system control and help protect loudspeakers in high-output environments.

With stable 2 ohm operation and an extremely high damping factor, the amplifier maintains excellent control over loudspeaker drivers, delivering tight, accurate low-frequency response even when driving large subwoofer arrays.

Cooling, Protection & Reliability

Designed for continuous professional use, the QX2-3000 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 in real-world installations.

The internally modular design allows for quick servicing and maintenance, making the amplifier particularly attractive for rental companies and venues operating large multi-amp systems.

Connectivity & Installation

Balanced XLR inputs ensure clean signal integration with professional mixing consoles, processors and system controllers. Professional speaker outputs and a 32A mains power connector provide the current handling required for high-power touring and installation systems.

Front panel status indicators display thermal conditions, fault states and limiter activity, allowing quick visual monitoring of system health during operation.
