The Bose S1 Pro Plus Mic/Line TX is designed for the wireless transmission of signals to the compact Bose S1 Pro Plus PA system. The wireless device can simply be connected directly to an instrument's output socket to tap its audio signal, and will run for six hours on a single charge. The unit has a range of 10 metres, so it can be used to wirelessly transmit a signal from an ordinary microphone, an on-stage mixing console, or any line signal with an XLR connection to the Bose S1 Pro Plus – or anywhere else in the entire venue. An integrated mute switch allows musicians to mute their own signal.
Thanks to its compact dimensions, the Bose S1 Pro Plus Mic/Line TX in its sleek black housing could scarcely be more unobtrusive, especially since it weighs just 102g. It has an XLR connection which will connect it directly to an instrument or other output, transmitting at a frequency of 2.4GHz. On the right-hand side of the transmitter is the on/off switch, and next to that is the mute button – that's all there is to it. The Bose S1 Pro Plus Mic/Line TX is charged either via its USB-C connection (opposite the XLR socket) or by inserting it into one of the two charging slots on the Bose S1 Pro Plus, which are located on the back of the larger unit, next to the channel inputs.
For more freedom of movement, many singers, presenters, and entertainers want to be able to transmit their voice wirelessly, speaking to the audience from all over the stage – or even handing the mic to someone in the audience. Wireless signal transmission makes live events endlessly flexible, and the Bose S1 Pro Plus Mic/Line TX is also remarkably easy to use. Simply connect it to a microphone and it's ready to go. The XLR socket is equipped with a secure push-switch for a reliable connection, so all users need to do is ensure the device is switched on and not muted.
Bose is an American manufacturer founded in 1964, and is known for its audio products designed with psychoacoustics in mind. The idea is to focus not on the performance of a loudspeaker, but on the perception of the sound. The 901 speaker system, which was produced from 1968 to 2008, became legendary. Bose manufactures audio technology for both private and professional use, from hearing aids to sound systems and from headphones to vehicle stereo systems.
To transmit a wireless stereo signal to a Bose S1 Pro Plus PA unit, two Bose S1 Pro Plus Mic/Line TX can be used simultaneously. This allows keyboardists, for example, to move around the stage with a keytar. Judicious use of the on/off switch will save power, meaning the integrated battery will have enough charge for longer. If the signal seems to be suffering from interference, a quick first diagnostic step would be to mute the transmitter's audio signal to check whether the interference is coming from the source itself – and not from the receiver. Bose also manufactures these compact and flexible transmitters with a 6.3mm jack, meaning all kinds of instruments can be connected to the Bose S1 Pro Plus base unit.
