Bose S1 Pro+ Wireless PA System and Wireless Mic/Line Transmitter – XLR

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.

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

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.

Tilt-back
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.

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.

Yes. The enhanced portability, easy setup, and professional sound quality of the S1 Pro+ system make 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" (6.35 mm) 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.

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.

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" (6.35 mm) TRS and 3.5 mm source.

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

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.

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.

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.

The S1 Pro+ is not water resistant.

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.

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.

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.

When you connect a wireless transmitter to a channel that 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.

NOTES:

• 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.

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.

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+.

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.”

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.

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