DETAILS

The Studiomaster QX2-1300 is a high-output, two-channel digital power amplifier designed for demanding professional audio installations and rental applications.

The QX2-1300 forms part of the Studiomaster QX Series of advanced digital power amplifiers, engineered to deliver extremely high efficiency and stable performance in high-current, low-impedance conditions. With over 95% operating efficiency and active power factor correction (PFC), the QX2-1300 provides powerful, reliable amplification while keeping energy consumption and heat generation to a minimum.

Housed in a compact 1U chassis and weighing just 12kg, the QX2-1300 is ideally suited to professional environments such as large-scale sound installations, touring systems, line array applications, live venues, conference facilities and rental companies. The universal switching power supply allows operation from 90–250VAC, ensuring consistent performance across a wide range of electrical environments.

Delivering up to 2 x 1100W at 4 ohms, and remaining stable down to 2 ohms, the QX2-1300 offers flexible deployment for high-power speaker systems. Stereo, parallel and bridge modes, selectable gain settings and an integrated output limiter make this amplifier highly adaptable for complex system designs and demanding real-world use.

Performance & Configuration

The QX2-1300 supports stereo, parallel and bridged operation, allowing the amplifier to be configured for a wide range of system layouts. Multiple selectable gain modes and a built-in output limiter provide precise control and system protection, making the amplifier suitable for both fixed installations and portable sound systems.

With stable operation down to 2 ohms and extremely high damping factor, the QX2-1300 maintains tight control over loudspeaker drivers, even in high-demand scenarios such as large subwoofer arrays or long cable runs.

Protection, Cooling & Connectivity

Designed for professional reliability, the QX2-1300 features a comprehensive protection system including thermal, overload and DC output protection. Variable speed fan cooling ensures efficient thermal management while minimising operational noise.

Balanced XLR inputs provide clean signal integration with professional mixing desks and processors, while professional speaker connectors and a 32A mains input socket make the amplifier suitable for high-power touring and installation environments. Front panel indicators display thermal status, faults and limiter activity for easy system monitoring.
