Portable wireless sound for any occasion...

Versatile, portable, powerful — the S1 Pro+ delivers professional-grade sound quality with a full-frequency range, spanning from 62Hz to 17kHz and a wide dispersion coverage of 120° H x 50° V, all packed within a compact, lightweight design. This makes it the perfect solution for your installation clients' portable audio requirements — whether indoors or outdoors. S1 Pro+ is ideal for awards ceremonies, small lecture halls and auditoriums, multipurpose spaces, fitness centers, parties/weddings, tailgate/pep rallies, and more.

..and for many applications.





The S1 Pro+ is always up for any get-together. With four positioning options and Auto EQ, it automatically senses the PA’s orientation to adjust settings for peak performance. Place it vertically, tilted back, horizontally, or on a speaker stand (its integrated speaker stand hole is compatible with standard 35mm stands).


Mixer on board… and on your smartphone.

Connect your equipment with an integrated 3-channel mixer and access controls including independent EQ, reverb, and ToneMatch presets with intelligent OLED displays. Or, get it all on your phone through the Bose Music app, which delivers intuitive mixing capability—right in the palm of your hand. 

Change the volume, tone and mixer settings instantly from your mobile device. Walk the room, hear how the mix sounds, and fine-tune as you go. And you can stream music right from your favorite app via Bluetooth® connectivity. 

Channels 1 and 2 for mics and instruments

Channel 3 for three additional audio inputs: 1/4" Line, aux 3.5mm, and Bluetooth® , which can be used simultaneously. 


No cords. No cables. No problem.

Optional XLR and instrument wireless RF transmitters give you the freedom to say goodbye to cables. Simply plug them in to your mic or instrument, and they effortless pair with the system’s integrated wireless RF receivers for up to 4 hours of play time. They store neatly in the loudspeaker and recharge when not in use.

More bass. Less space.

For more punch and low-frequency performance, the Bose Sub1 bass module makes the perfect complement. The optimized EQ setting of the S1 Pro+ pairs perfectly with the Sub1 to deliver room-filling sound in a space-saving footprint.

The Sub1 features an integrated subwoofer with a unique RaceTrack driver design for amazingly powerful bass. Its slim 7×13" driver delivers performance that rivals a conventional 12" woofer—but in a smaller and less cumbersome package.


Battery-powered for go-anywhere sound.

No external power source? Its rechargeable lithium-ion battery provides up to 11 hours of play time* on a single charge and can be easily swapped out for a fresh spare for extended play time.

Rugged and lightweight, the S1 Pro+ is designed for durability and transport using the convenient carry handle. And at just 14.4 lbs., it’s a breeze to bring to any location.

*As with any battery-operated device, battery performance can vary based on a number of different factors.

What makes the Bose S1 Pro+ Wireless PA System different from other PA systems?

The S1 Pro+ is the ultimate all-in-one PA, floor monitor, practice amplifier, and primary music system. Multiple positions, supported by Auto EQ, ensure that you always sound your best. And with a 3-channel mixer, reverb, Bluetooth streaming along with integrated wireless receivers, the S1 Pro+ is ready to be your go-anywhere PA.

How do I set the system up?

  1. Choose your system orientation based on the application
  2. Plug in the AC power cord or use battery
  3. Turn the power on and turn up the volume controls
  4. Connect the audio source with a wire or wirelessly with the optional wireless transmitters accessories. If using a guitar or microphone, set the ToneMatch switch to the appropriate setting and dial it in even further with the Bose Music app

What is the optimal placement when using the S1 Pro+?

The versatile S1 Pro+ System operates in four unique modes and can be set up differently based on the application.

Elevated surface
Position the S1 Pro+ on a surface. This projects sound clearly and evenly throughout the audience, and ensures that audience members enjoy the full frequency range of the system.

For performances where your audience is close to you, tilt the S1 Pro+ onto its back edge. For best results, you should stand or sit to one side of the loudspeaker to avoid blocking sound from the audience.

Monitor mode
To use the S1 Pro+ as a personal floor monitor, place it on the ground horizontally, in front of and pointing toward the performer. Tilt the loudspeaker onto its side edge. Rotate the Bose logo counterclockwise to match your chosen mode.

Speaker stand
Place one or two S1 Pro+ Systems on speaker stands (sold separately) for general-purpose sound reinforcement.

What function does Auto EQ perform?

Auto EQ provides optimal performance by sensing the orientation of the S1 Pro+ multi-position PA System using internal sensors. Once placed into a new position, the system applies the optimal equalization curve to maximize the quality of sound.

Is the S1 Pro+ multi-position PA System designed for mobile DJs?

Yes. The enhanced portability, easy set-up, and professional sound quality of the S1 Pro+ System makes it suitable for a variety of applications as a smaller PA system: DJs, community and athletic events, business presentations, or wherever high-performance and easy-to-use sound amplification is needed.

The S1 Pro+ features Bluetooth streaming with one-button pairing. A ¼" TRS input and a 3.5 mm input allow for connecting additional wired sources like a DJ mixer, laptop, CD, or portable audio device. When making announcements, simply plug a dynamic handheld microphone into one of the microphone/instrument channels.

Two S1 Pro+ Systems are recommended for DJ applications to help reproduce stereo sound. Additionally, a single S1 Pro+ System can be conveniently used as a satellite system for larger DJ events.

What are the benefits of the integrated ToneMatch processing?

Whether you’re using an acoustic guitar or a handheld dynamic microphone, ToneMatch allows you to match the sound of the source by maximizing the sonic properties through equalization.

How many channels does the S1 Pro+ System have?

Three. The S1 Pro+ System has two full-featured channels designed for live speech or musical performance and one channel dedicated to prerecorded material using Bluetooth streaming or a ¼" TRS and 3.5 mm source.

Does the S1 Pro+ multi-position PA System have an analog audio output for expansion?

Yes. The S1 Pro+ multi-position PA System has a XLR balanced line output to send the master mix out to another S1 Pro+ or to an audio console.

Are the S1 Pro+ Systems compatible with T4S/T8S ToneMatch mixers?

Yes. However, please note that the optional ToneMatch power supply is required for operation. For musical performances that require access to our most advanced tone shaping library, a full suite of studio quality effects, dynamics processing, and expanded inputs and outputs, ToneMatch mixers are the recommended choice.

To use the T4S/T8S ToneMatch mixer with the S1 Pro+ multi-position PA System, connect a master output of the ToneMatch mixer to input 1 or 2 on the S1 Pro+ System. Adjust the master level of the ToneMatch mixer to at least 50% and adjust the S1 Pro+ input volume knob to the desired level.

How can I take advantage of instruments or devices that deliver stereo output?

A single S1 Pro+ multi-position PA System can combine the two channels and fill the venue with one speaker. For instruments or recorded material where stereo reproduction is essential, two S1 Pro+ Systems can be used to deliver stereo sound.

How are you able to obtain such a high level of performance from a smaller system?

Great care was taken in the design process to ensure that all the speakers and electronics perform as one integrated system. This allows the S1 Pro+ multi-position PA System to be extremely efficient and maximize its acoustical output while maintaining its small profile.

Is the S1 Pro+ water resistant?

The S1 Pro+ is not water resistant.

Can I connect an external subwoofer, such as the Bose Sub1 or Sub2 bass module, to the S1 Pro+ Wireless PA System?

You can use Sub EQ with any powered subwoofer, but for optimal performance, we recommend the Bose Sub1 or Sub2 Powered Bass Modules. The S1 Pro+ includes a Sub EQ setting and is a crossover that optimizes system EQ for setup scenarios in which a powered subwoofer is connected to the system LINE OUT port. Once you enable Sub EQ, it stays enabled until you disable it, or the system powers off.

For information on how to connect the system to a Bose Sub1 or Sub2 Powered Bass Module, refer to the Bose Sub1 & Sub2 Powered Bass Module Owner’s guide. Visit the Bose Portable PA support section.

Where should the S1 Pro+ Wireless PA System be positioned on stage?

System placement requirements for the S1 Pro+ multi-position PA System are flexible. For optimal sound for both the audience and performer, position the system directly behind — or behind and slightly off to one side of — the performer.

Does the S1 Pro+ have a universal power supply, so it can be used with any wall outlet?

Yes. The S1 Pro+ has a universal power supply that allows it to operate in regions ranging from 100V – 240V. The proper power cord for the specific region in which the system was purchased is included in the product carton.

What is Insert Mode and how do I use it?

When you connect a wireless transmitter to a channel which has the Insert setting set to Auto, the ¼" (6.35 mm) TRS channel input becomes a series channel insert (also known as an effects loop). You can connect effects units or pedals to the input using an insert cable, all while using your instrument or mic wirelessly.


  • An insert cable (¼" or 6.35 mm TRS to dual ¼" or 6.35 mm TS) is required to connect an effects unit to a channel insert. You can purchase an insert cable at your local music retailer. 
  • Don’t connect an instrument or other audio source to the input using a standard ¼" (6.35 mm) cable when a wireless transmitter is connected to the channel. This prevents audio from playing from both the wired and wireless source.

What is Live Stream mode?

Live Stream mode allows the system to be recognized as an audio interface when you connect it to your computer using a USB-C® cable. This lets you perform live for an online audience or record audio directly to your computer’s digital audio workstation (DAW).

When Live Stream mode is enabled, the system passes a dual mono mix of Channels 1, 2, and 3 to a connected computer. In this mode, the channel volume controls behave like faders on a mixer. Adjusting channel volume using either the channel controls or the Bose Music app, adjusts the level of that channel within the mix being sent to your computer.

A monitor volume control also appears on Channel 3, allowing you to adjust the master volume of the system speakers without affecting the computer mix. Once you enable Live Stream mode, it stays enabled until you disable it, or the system powers off.

Can the S1 Pro+ Wireless PA System be used together with an L1 System?

Yes. All systems can share the same stage. The L1 Compact and L1 Model II Systems have longer line arrays than the S1 Pro+ and can project sound further with less drop-off of sound levels than the smaller array found on the S1 Pro+.

How does the Bose Music app work with the S1 Pro+?

Using the app, you can control the system remotely, manage system settings, and access exclusive features like ToneMatch preset customization, channel and reverb mute, saved Scenes, and Dual Wireless Streaming. If you have already created a Bose Music app account for another Bose product, see “Add the system to an existing account.”

What is Dual Wireless Streaming?

The Dual Wireless Streaming feature in the Bose Music app lets you play Bluetooth audio from both the system and another compatible Bose system at the same time in either dual mono or stereo. You can access this option from the Settings menu.

Compatible systems include:

Bose S1 Pro+ Wireless PA System
Bose L1 Pro8 & L1 Pro16 Portable Line Array System
Bose L1 Pro32 Portable Line Array
More systems may be added periodically.

What is the warranty period on the S1 Pro+ multi-position PA System?

The S1 Pro+ multi-position PA System has a two-year limited warranty.
