Size: 49 x 26.5mm / 1.93 x 1.04" Display Size: 24 x 15mm / 0.94 x 0.59" Instruction: 1, Use battery or step-down transformer type regulated power supply as power source. Switch-mode power supply without filter such as power bank, phone charger, switch voltage regulated DC-DC module can NOT be used because the conversion interference of switch-mode power supply will affect this module. 2, If you need USB audio broadcast function, you need to plug in USB cable and connect module to a computer. 3, If you need LINE channel as a source of sound emission, plug on end of audio cable into 3.5mm audio socket, and the other end into your audio equipment (e.g. mobile phone), then the module will automatic switch to LINE channel. 4, If you need this module MIC as a source of sound emission, simply unplug the USB and LINE, and module automatically switches to MIC channel as the source of FM. Note: 1, Power supply voltage must be DC 3V to 5V. 2, Do NOT touch the back of the module components when it is working, otherwise it will probably not work normally or burn out from a short circuit. Package Includes: 1 x Module Review: Great. And for only £10, even greater. - For the price, absolutely fantastic. For around £10, you get a fully functional transmitter with great sound quality. It probably puts out a dodgy signal, as when I power it on, I can barely pick up other stations—but the power is so low that it doesn’t really matter. The sound itself is brilliant, with clear highs and strongly defined bass. Stereo channels are swapped round, though, so you’ll have to fix that in software. By attaching this to a stretched-out coat hanger (the best antenna the world has ever seen!), I can comfortably get to the end of my road—and it goes out even beyond that, though it starts to break up. This is around 0.1 miles of range, and I’m sure you could go further with, y’know … an actual antenna. Could you buy better? Sure. But if you’re spending £10 on a transmitter, buying better probably isn’t your goal. For the price, and for what it is, it’s excellent. Review: Nice cheap kit - Set up with a 70cm wire antenna connected to an old mp3 player and signal reached end of street. Might half the antenna length as don’t need or going that far. There was a bit of hum but after adding a ground wire of similar length to the transmitter the hum has now gone. Shame it’s micro USB not USB-C. The other issue is my one anyway transmits slightly of what you programme into it. So for stereo 87.5Mhz becomes 87.55Mhz. Apparently that’s down to low chrysal quality on the board. ## Features - Advanced digital audio processing (DSP) and FM phase-locked loop modulation technique (PLL) ensure less sound distortion and more stable performance - LCD display is more intuitive and accurate, and has very low power consumption and tiny noise interference - Built-in 30-class digital volume adjustment can easily complete volume adjustment by pressing buttons - Automatic storing data when the power is out - Using quartz crystal for frequency stabilization, and emission frequency will not drift when temperature changes ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0762JM715 | | Antenna Location | Podcasting, Streaming, Video Recording, Karaoke | | Audible Noise | 30 Decibels | | Audio Sensitivity | 30 Decibels | | Box Contents | Battery, Transmitter, USB Cable | | Brand | Walfront | | Brand Name | Walfront | | Colour | Multicolor | | Compatible Devices | Personal Computer | | Compatible devices | Personal Computer | | Connectivity Technology | USB | | Connectivity technology | USB | | Connector Type | USB | | Connector type | USB | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 20 Reviews | | Enclosure Material | Metal plastic | | Frequency Range | 0.05 khz 18 khz | | Frequency Response | 18 KHz | | Hardware Platform | Smartphone | | Impedance | 32 Ohms | | Item Weight | 0.02 Pounds | | Manufacturer | Walfront | | Manufacturer Part Number | Walfrontw6a1xpg4n2 | | Microphone Form Factor | Handheld | | Model Number | Walfrontw6a1xpg4n2 | | Number of Channels | 1 | | Power Source | Battery Powered, Corded Electric | | Recommended uses for product | Podcasting, Streaming, Video Recording, Karaoke | | Special Feature | Volume Control | | Special feature | Volume Control | | UPC | 663862243109 | ## Product Details - **Audio sensitivity:** 30 Decibels - **Brand:** Walfront - **Colour:** Multicolor - **Compatible devices:** Personal Computer - **Connectivity technology:** USB - **Connector type:** USB - **Included components:** Battery, Transmitter, USB Cable - **Item weight:** 0.02 Pounds - **Recommended uses for product:** Podcasting, Streaming, Video Recording, Karaoke - **Special feature:** Volume Control ## Images ![Walfront DSP & PLL Digital Wireless Microphone Stereo FM Transmitter Module 87-108MHz - Image 1](https://m.media-amazon.com/images/I/61CeESKQXwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great.

Very clear transmission and easy to set the volume and frequency. Bought to use as a fm transmitter for the Halloween show on my house. Can’t wait to see and now hear it. 👍 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/51572779-walfront-dsp-and-pll-digital-wireless-microphone-stereo-fm-transmitter](https://www.desertcart.pl/products/51572779-walfront-dsp-and-pll-digital-wireless-microphone-stereo-fm-transmitter) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-06-01*
