QTX is a UK audio and lighting brand launched in 2009 as part of the AVSL Group, a Manchester-based electrical distributor. The brand sits at the budget-to-mid tier of the live sound and entertainment market, with products distributed widely through UK and European retailers like Gear4music, DJKit, and Sound Services rather than through boutique pro-audio dealers.

The sound side of the catalog centers on portable PA systems aimed at mobile DJs, buskers, fitness instructors, and small-venue entertainers. Notable lines include the QR PABT series of battery-powered active PA speakers (available in 8", 10", 12", and 15" formats), the QXPA series with built-in Bluetooth and VHF wireless microphones, and the PAL series with TWS pairing and onboard LED effects. The range extends to powered and passive loudspeakers, power amplifiers, wireless microphone systems, and audio accessories such as cables and connectors.

Alongside audio, QTX produces a broad lighting and effects catalog — LED PAR cans (the SmartLIGHT family), moving heads, multi-effect fixtures like the TetraCube (combining RGB wash, strobe, magic ball, and laser), party lights, mirror balls, fog and haze machines, bubble and snow machines, and DMX controllers. The combined sound-and-light scope is reflected in the brand's positioning toward clubs, bars, schools, theatres, and event entertainers who need affordable all-in-one solutions.

QTX has 2 products cataloged on Equipboard, including Guitar Power Amplifiers.
