Description
The QTX VH1 is a VHF wireless microphone system built around a half-width 1U receiver and a handheld transmitter. It runs on 173.8MHz, which is license-free in the UK, so you can set it up and use it without any paperwork or ongoing fees. That makes it a sensible pick for schools, clubs, small venues and anyone who wants a straightforward radio mic (US: wireless microphone) without extra cost.
You get up to 50m of range between the transmitter and receiver, which covers most rooms and halls with room to spare. The handheld transmitter runs on a single 9V PP3 battery, and both the battery and a jack lead are supplied in the box, so there is nothing else to buy before you start. The receiver takes its power from a 10Vac 250mA supply, also included, and offers both XLR and 6.3mm jack outputs so it connects easily to a mixer, amplifier or powered speaker.
Audio performance is solid for the price, with a signal-to-noise ratio of more than 85dB and total harmonic distortion (THD) under 0.2%. The handheld transmitter measures 270mm long by 45mm in diameter and weighs 190g without its battery, so it sits comfortably in the hand. The receiver measures 45 x 210 x 180mm and weighs 573g. If you need a simple, self-contained wireless setup for speech or vocals, the VH1 gives you the essentials in one box.
