Positive Grid Spark Link XLR

The Positive Grid Spark LINK XLR is a wireless XLR audio system for dynamic microphones and more. This compact, portable system replaces your microphone cable with a reliable digital 2.4GHz connection with studio-quality sound. Connect the transmitter (TX) to your dynamic microphone and plug the receiver (RX) into the XLR input of a PA, mixer or audio interface - within seconds you have a wireless connection. Spark LINK XLR is ready to use right out of the box, with automatic pairing and all necessary accessories included. It is ideal for performing musicians, singers, content creators and speakers who want to move freely without the hassle of cables.

Professional sound quality
Despite its wireless convenience, Spark LINK XLR delivers uncompressed, full-range sound with 24-bit/48kHz audio resolution. The frequency range of 20 Hz to 20 kHz ensures that every nuance of your voice or instrument is transmitted. With a dynamic range of 103.7 dB, both soft and loud passages remain clear and detailed, so your audience won't miss a thing about your performance.

Ultra-low latency
Live performers will appreciate Spark LINK XLR's ultra-low latency. At <3 milliseconds, the signal delay is practically zero. So you hear yourself back in real time without noticeable "lag" or echo. This means your vocals or speech stay perfectly in sync with your performance - no distractions, just focus on your sound.

Complete wireless freedom
With Spark LINK XLR, you get total freedom of movement on stage. The stable 2.4GHz connection offers a range of up to ~21 meters (line of sight), so you can walk around unhindered without signal loss or dropouts. The built-in lithium-ion battery lasts up to about 7 hours on a single charge - more than enough for a long play session, gig or presentation - and is fully recharged in about 2 hours via the USB-C connection. So you don't have to worry about failing halfway through.

Plug-and-play convenience
Ease of use is paramount: as soon as you turn on the transmitter and receiver, they automatically pair with each other. No need to scour frequency channels or go through complicated menus. LED indicators on both units show you at a glance whether your connection is active and the status of the battery. In addition, the transmitter features a mute function: at the touch of a button, you can quickly mute or unmute the microphone - useful for interim announcements or to prevent feedback. You can use up to four Spark LINK XLR sets simultaneously in the same room without interference, meaning an entire band can go wireless without any problems.

Spark LINK XLR is designed for dynamic microphones (XLR) that do not require phantom power. So condenser microphones are not supported (no 48V phantom power is transmitted). In addition to microphones, you can also wirelessly connect other XLR devices with microphone-level output - for example, a DI box or modeler - to your mixer or PA, if necessary. The system is robust but lightweight and hangs directly from your microphone and mixer, without a separate bodypack or long cable. Spark LINK XLR comes complete with both the transmitter and receiver, a USB-C to USB-C charging cable (1.5 m) and a manual, so you can get started right away.
