Why the S1 Pro+ Wireless Instrument Jack Transmitter makes sense on stage
Instead of managing another instrument cable, you can keep your stage area tidier and move more naturally while playing. The wireless connection helps you step forward, change position or engage the audience without unplugging. Built-in charging and onboard storage reduce the risk of misplacing accessories between sets. This transmitter is especially well suited to solo performers, duos and mobile musicians using guitar, keyboard or similar 6.3 mm Jack (1/4-inch) sources with the S1 Pro+ active speaker, whether for rehearsals, small venues, corporate events or quick setup situations.
What makes this wireless instrument transmitter different
What separates this model from many generic plug-in wireless systems is how closely it works with the Bose S1 Pro+ Battery-Powered Active Speaker platform. There is no separate receiver to mount, power or carry, because the S1 Pro+ already has wireless receivers built into Channels 1 and 2. Pairing happens directly through the speaker, and the transmitter recharges there between uses or by USB-C when needed. For performers who value portability, fewer loose components and a streamlined workflow, that integrated Bose design is the main reason to choose it.

How to get started with the S1 Pro+ Wireless Instrument Jack Transmitter
Start by powering your Bose S1 Pro+ Wireless PA System. Remove the cap from the wireless transmitter charging port for Channel 1 or 2, insert the transmitter fully, and wait about five seconds for pairing to complete. While docked, the transmitter also begins charging. When you are ready to play, press and release the back of the transmitter to remove it, connect it to your instrument’s 6.3 mm (1/4-inch) Jack output, and power it on. For smooth operation, charge it before longer sessions and store it back inside the speaker after use.
