{"product_id":"qtx-vh45b-handheld-vhf-wireless-microphone-system","title":"QTX VH45B Handheld VHF Wireless Microphone System","description":"\u003ch5\u003eDescription\u003c\/h5\u003e\n\u003cp\u003eThe QTX VH45B is a handheld VHF wireless microphone system built around a compact desktop receiver. It runs on a fixed operating frequency of 174.5MHz and gives you a working range of up to 50 metres, which suits small venues, presentations, karaoke and community events where you need to move around without a trailing cable.\u003c\/p\u003e\n\u003cp\u003eEverything you need to get going comes in the box. The receiver takes a 9 to 15Vdc 200mA power supply, and the handheld transmitter runs on a 9V PP3 battery, both supplied. A 6.3mm jack lead is included too, so you can connect the receiver straight to a mixer, amp or powered speaker. The transmitter has on\/off and mute controls on the body, letting you cut the audio between uses without switching off the whole unit.\u003c\/p\u003e\n\u003cp\u003eOn the performance side, the system posts a signal to noise ratio of more than 85dB and total harmonic distortion below 0.2%, so speech and vocals come through clean. The handheld transmitter measures 250 x 50mm in diameter and weighs 280g, while the receiver is a small 150 x 110 x 35mm and weighs 190g, so it sits neatly on a desk or shelf. Note that VHF (very high frequency) systems use a single fixed channel, so this is a straightforward one-mic setup rather than a multi-channel rig.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply : receiver\u003c\/td\u003e\n\u003ctd\u003e9 - 15Vdc 200mA (supplied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery : transmitter\u003c\/td\u003e\n\u003ctd\u003e9V PP3 (supplied)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating frequency\u003c\/td\u003e\n\u003ctd\u003e174.5MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum range\u003c\/td\u003e\n\u003ctd\u003e50.0m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput connection\u003c\/td\u003e\n\u003ctd\u003e6.3mm jack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eS\/N ratio\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;85dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTHD\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;0.2%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions : transmitter\u003c\/td\u003e\n\u003ctd\u003e250mm x 50mmØ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions : receiver\u003c\/td\u003e\n\u003ctd\u003e150mm x 110mm x 35mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight : transmitter\u003c\/td\u003e\n\u003ctd\u003e0.28KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight : receiver\u003c\/td\u003e\n\u003ctd\u003e0.19KG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/171801UK_2a925ddb-e70e-41fc-bc63-696c81b2c39a.pdf?v=1784987302\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is supplied in the box?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe VH45B comes with the handheld transmitter, desktop receiver, a receiver power supply, a 9V PP3 battery for the transmitter and a 6.3mm jack signal lead.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat frequency does it run on?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt operates on a single fixed VHF frequency of 174.5MHz.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow far will the microphone work?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe maximum range is 50 metres in good conditions with clear line of sight to the receiver.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I connect the receiver to my system?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe receiver uses a 6.3mm jack output, so you can run the supplied lead into a mixer, amplifier or powered speaker.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I run more than one microphone at once?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. This is a single-channel VHF system on one fixed frequency, so it is designed for one microphone at a time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow is the transmitter powered?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe handheld transmitter runs on a single 9V PP3 battery, which is supplied.
