Rated 5 out of 5 by from Excellent Tonal Range I use this for karaoke mainly. Mostly Indian bollywood karaoke, for which the background music is very demanding; not just guitar for instance. The S1 Pro handles it all. Voice comes through clean and clear and the reverb is fine. I am fussy about fidelity in speakers, and really, am quite pleased with the S1 Pro. Mostly I use it hooked up to a Mackie Mixer at home but I could use it at someone's home on battery I guess, without a mixer. Volume seems fine for a group of up to 50 people, though a friend performed at a busy restaurant with probably over 100 people seated, all talking, :) but yet we could clearly hear his vocal/guitar performance. He would have done well to have a set of two S1 Pros. Bass is really very good for a 15 pound speaker but I'm not surprised because my SoundLink is small and yet has good bass.

What makes the Bose S1 Pro multi-position PA system different to 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 three-channel mixer, reverb, Bluetooth® streaming and ToneMatch processing on board, 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 cable or use the battery
  3. Connect audio source. If using a guitar or microphone, set the ToneMatch switch to the appropriate setting
  4. Turn the power on and turn up the volume controls

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 an elevated 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 reaching 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 towards the performer. Tilt the loudspeaker onto its side edge. Rotate the Bose logo anticlockwise 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 in a new position, the system applies the optimal equalisation curve to maximise sound quality.

Given its smaller size, does the S1 Pro system project sound as far as the L1 Compact system?

The S1 Pro multi-position PA system produces horizontal coverage that is comparable to that of L1 systems. Longer line arrays, such as those found in these systems, can project sound further with less dropoff of sound levels than the smaller array found in the S1 Pro.

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

Yes. The enhanced portability, easy setup 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 best-in-class Bluetooth® streaming with one-button pairing. A 3.5-mm input for connecting a DJ mixer, laptop, CD player or portable audio device allows for wired operation. 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 maximising the sonic properties through equalisation.

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 3.5-mm source.

Does the S1 Pro multi-position PA system have an analogue audio output for expansion?

Yes. The S1 Pro multi-position PA system has a 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 of the speakers and electronics perform as one integrated system. This allows the S1 Pro multi-position PA system to be extremely efficient and maximise its acoustic 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 B1 bass module, to the S1 Pro multi-position PA system?

No. The system does not support adding bass modules. However, the S1 Pro does provide a reasonable amount of bass from its integrated high excursion woofer.

Where should the S1 Pro multi-position 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 to one side of—the performer.

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

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

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.

Can the S1 Pro multi-position 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 dropoff of sound levels than the smaller array found on the S1 Pro.

Where can I learn more about the S1 Pro multi-position PA system or L1 portable line array systems and obtain tips on maximising the benefits of my system?
