Positive Grid Spark Link Wireless System

Spark LINK: A Positive Grid Solution Designed for Modern Playing, Both in Rehearsal and on Stage

Designed to simplify wireless access, the Spark LINK focuses on the essentials: fast connection, intuitive use, and stability suited for demanding environments. Its management of 4 channels allows equipping multiple musicians without multiplying constraints, while maintaining immediate startup.

Who Is the Spark LINK For?

The Positive Grid Spark LINK is made for guitarists and bassists who want to regain the feel of a cable without the clutter. It is also well suited for instruments equipped with an output (electro-acoustic guitar, etc.). In rehearsal, it facilitates positioning and movement; on stage, it helps keep the setup clean and allows freer playing without sacrificing responsiveness.

Audio Performance and Ergonomics: Simplicity, Low Latency, and Compatibility

Detailed and Responsive Audio

With a frequency response from 20Hz to 20kHz and 48kHz / 24-bit conversion, the Spark LINK aims for clear and precise sound reproduction. Its latency under 3ms helps maintain a natural playing feel, especially appreciated on tight rhythms and fast passages.

2.4GHz Wireless and Comfortable Range

The connectivity relies on a proprietary Positive Grid wireless audio system at 2.4GHz, with a stated range of up to 21 meters line of sight. Convenient for stage, rehearsals, and studios where freedom of movement is desired.

Adaptive Design and Convenient Charging

The 110deg angled jack secures the connection on various guitar bodies and sometimes challenging configurations (front jack, side jack, tight spaces). Charging is done via USB Type-C, and the included cable facilitates daily power supply.
