The QST QX-1 is a classic Class AB power amplifier designed to perform equally well in home audio, karaoke, studio, and PA systems. Unlike traditional pro amplifiers, the QX-1 features a clean, modern design that looks just as good in a living room as it does in a rack.
Built with an all-aluminum chassis, aluminum volume knobs, and a gloss black front panel, the QX-1 combines premium aesthetics with serious power. Its high-current Class AB output stage delivers smooth, natural sound, clear vocals, and deep, controlled bass.
Designed for 110–120V / 15A North American power, the QX-1 delivers up to 600 W × 2 at 8 Ω, 700 W × 2 at 4 Ω, or up to 1500 W bridged (depending on load and operating conditions).
Balanced XLR inputs ensure clean signal input, while SpeakON outputs and binding posts support both professional PA speakers and high-fidelity home speakers. Built-in protection and limiter circuits help safeguard your system, with Stereo, Parallel, and Bridged modes for flexible system setups.
One amplifier. Any system.
Important:
This unit is a power amplifier only and requires an external preamplifier or audio source with volume control to produce sound.
Use Cases:
External power amplifier for home theater receivers to drive larger or more demanding speakers
Power amplifier for karaoke systems
Bridged mono operation for subwoofers
Stereo power amplifier paired with a preamp for hi-fi audio systems
