Gain Staging

For each channel you are using on the S1 Pro System,

  1. Turn the channel volume off
  2. Connect your sound source
  3. Set the source outputs (ToneMatch mixer, third party mixer, or instruments) to the maximum you will use during your performance.
  4. While playing/singing as loud as you will during your performance, bring up the channel volume until you see solid green on the channel indicator light. Occasional flickers of red are okay. If you see solid red or you hear distortion, turn down the volume.

Input Gain

Microphone vs Guitar Volume

Question
Why do I have to turn up the microphone higher than guitar?
Answer
The output level of the guitar is louder than the output level of the microphone. That's why we have to turn up the microphone higher.


In the picture above the

  1. Microphone is connected to channel 1
  2. Guitar is connected to channel 2

The volume on channel 1 (microphone) is higher than on channel 2 (guitar) because the signal from the microphone is lower than from the guitar.


More information
  • The power amps are running at full volume
  • The volume controls are trim controls:
  • Note how quiet the S1 Pro is when there’s no input source and the volume, is all the way up – The volume controls are trim not preamp/gain controls
  • The center détente is a convenient point of reference, especially when you can't see the controls well at a gig
    It is not an indication of a specific amount of gain
  • When you turn the volume controls all the way up, you have reached the maximum volume the S1 Pro is capable of producing for that source
  • Note the clip lights. If you see red, turn down to avoid distortion. You have reached the maximum usable volume just below clipping

We hit maximum usable volume for an input is just before the clip lights come on. With a guitar with a preamp, that might be at 12:00 o’clock compared to a microphone at 3:00-4:00 o’clock.  There’s no dysfunction here. It’s a reflection that the output level of the guitar is higher than the microphone.



ToneMatch® Presets

On Channels 1 and 2 you can select a ToneMatch® Preset.

S1 Pro ToneMatch Switch.jpg

These are the equivalent Presets on the ToneMatch® mixers (T1, T4S, T8S)

Off

Category: Utility
Preset: Flat

L1® Compact equivalent: Channel 2, Line Level (switch position down)

Guitar

Category: Acoustic Guitars
Preset: Steel String w/piezo

L1® Compact equivalent: Channel 2, Guitar (switch position up)

Microphone

Category: Vocal Mics
Preset: Handheld Mics

L1® Compact equivalent: Channel 1

The Microphone Preset includes a sharp low-cut filter, keeping only that part of the audio spectrum where the microphone is useful. Using the microphone with this preset minimizes bass regeneration. The microphone preset was developed for close microphone use (“eat the mic”), which is the best way to optimize your vocal signal for tone and gain before feedback[1].
About the presets: No mic that I know of sounds good for close vocal, even for recording for that matter. All our presets compensate for this. A lot of these mics sound a lot more natural when you back off a foot or so from them. Of course, this is true in the studio too. No one does this for a live performance (backs very far off the mic) since you want to maximize gain before feedback by eating the mic. And so then you get funny sound and so then you need our presets to make it natural. [2]

S1 Pro Battery

Run Time

Up to 11 hours of play .

The full output of the S1 Pro system is available even when running on the internal battery. This is unlike some systems that throttle performance to extend the battery life.

Charging Times

Estimates:

  • 6.0 hours Trickle charge (system idle, connected to AC Power), switch in Off or Play position
  • 2.5 hours Fast charge (connected to AC Power), switch in Fast Charge (down) position


Checking the Battery Level

To check the battery, turn on the S1 Pro (switch in the top position). Wait until the power light is steady blue. Double tap the Bluetooth button (tap tap in under a second). Count how many times the power light blinks before returning to steady blue.

NOTE If you are running your S1 Pro System and battery LED turns solid red - the battery is nearly out of power. Connect to AC power to keep the show going.

Flying with the Lithium Ion Battery

Here's some information about Flying with Lithium Ion batteries from the FAA

https://www.faa.gov/about/init.../more_info/?hazmat=7

Size limits: Lithium metal (non-rechargeable) batteries are limited to 2 grams of lithium per battery. Lithium ion (rechargeable) batteries are limited to a rating of 100 watt hours (Wh) per battery. These limits allow for nearly all types of lithium batteries used by the average person in their electronic devices. With airline approval, passengers may also carry up to two spare larger lithium ion batteries (101-160 watt hours). This size covers the larger after-market extended-life laptop computer batteries and some larger batteries used in professional audio/visual equipment.

The battery in the S1 Pro is rated at 79.20 Wh. That's not in the documentation, but it is on the label on the battery.

Pole Cup Switch

The S1 Pro uses an accelerometer to determine if it is in the tilt-back, horizontal or vertical position. It also has a switch inside the pole cup to determine if it is mounted on a speaker stand. Based on the orientation and the switch, the S1 Pro automatically applies the correct EQ. If you depress the switch the speaker stand EQ is applied regardless of the orientation of the S1 Pro.

Here's a picture of the switch inside the pole cup.

S1 Pole Cup 1.png

S1 Pole Cup 2.png

Warning - Do NOT use Speaker Stands Like This

Ultimate Support TS30.png

Bose recommends using speaker stands that have solid, smooth surfaces. Do not use stands like the one shown to the right. It will damage the switch in the pole cup.


Channel 3 Volume Control

Slow to Respond

If you find the volume control seems slow to respond (especially between 7-11 o'clock) please turn up the volume at the source (Bluetooth or physical connection).

S1 Pro Channel 3

Steps in Volume

The S1 Pro has a digital gain knob on channel 3 which is divided into incremental steps. When you slowly turn the volume knob up with a strong input signal present, you may hear steps in loudness.

We are aware of this behavior and it is not a symptom of a fault or malfunction.

Noisy Volume Controls

On S1 Pro system channels 1 and 2: When you rotate the volume controls back and forth within 10 seconds of turning on the unit, you may hear a scratchy sound.

This is not a symptom of a hardware issue with the volume controls that warrants concern.

The noise is related to a start-up process within the unit, not the volume controls. The noise you hear is not the result of a physical problem with the volume controls.

When you turn on the unit and rapidly turn one of the volume controls back and forth you may hear a noise. This can happen on either channel, 1 or 2.

After several seconds, the sound stops. At this point, the volume controls on both channels 1 and 2 should work as expected, quietly.

If you cycle the power off and back on, you can get the same result on the other channel, 1 or 2.

If you turn on the unit and let it sit for 20 seconds, the volume controls are quiet. That doesn't mean you have to wait for 20 seconds before you can use the unit. You just have to wait for 20 seconds if you don't want to hear the noise when you rotate the volume controls quickly.

Orientations and Dispersion

Dispersion

In the speaker stand, tabletop, and tilt-back orientations

  • Horizontal 120 degrees
  • Vertical 50 degress

In the Horizontal (monitor) orientation

  • Horizontal 50 degrees
  • Vertical 120 Degrees

Auto EQ

If you take a loudspeaker and put it on a speaker stand, then a table top, and then on the floor, the sound will change*. When the speaker is on a table top or the floor, it is interacting with the boundaries (table top, floor, walls and ceiling too). This means, if you want great sound in all situations you have to EQ the loudspeaker.

Bose tuned the S1 Pro to sound great in all four positions (speaker stand, table top, floor (both tilt-back and horizontal)) taking into account the boundaries. And the engineers carefully considered how you would be using the S1 Pro . That's why there are two settings for the floor (tilt-back and monitor).

I encourage you not to second-guess the automatic EQ. To use them in ways other than Bose intended you'd have to put the loudspeaker in a free field (a room without reflections).

But if you could put the S1 Pro in a free field here's what might hear.

Using the speaker stand position as a reference:

   Table top: a little less bass than speaker stand
   Tilt-back: a little less bass than Table top.
   Horizontal: about the same as Tilt-back except there's some EQ treatment to support use as a monitor.

Line Out

¼ inch (6mm) Tip-Ring-Sleeve jack: Nominal +2.4 dBu, Max +20 dBu

Output Impedance: 9.4 kilo-ohm kΩ

Note: Using a Tip-Sleeve unbalanced cable will result in a drop in the audio level of -6dBu.

Note: There is no limiter on this output so you may get more than the rated maximum, but it could sound distorted.

Bluetooth

Version

The S1 Pro system supports Bluetooth version 4.2

Bluetooth Pairing

  1. Turn on the Bluetooth feature on your mobile device.
    Note: The Bluetooth feature is usually found in the Settings menu.
  2. Press and hold the Bluetooth Pair button for two seconds.
    Note: When ready to pair, the Bluetooth button will flash white.
  3. Select your Bose® SI Pro system from the device list.

Note: When the device pairs successfully, the Bluetooth button will turn solid white. Note: If your paired phone receives a call, any music playing will be paused and the ring will come through the phone: no calls or notifications will come through the SI Pro.

Once you have paired the S1 Pro system to a Bluetooth device, the S1 Pro system will automatically connect to that device when you turn on the S1 Pro system if it is powered on and within range. If you want to terminate that connection, terminate the connection on the Bluetooth device.

Clear the Bluetooth Pairing List

  1. Press and hold the Bluetooth button. until it goes dark (about 7-10 seconds).
  2. On your Bluetooth device, remove the Bose S1 Pro from the device list.

You are now ready to pair the S1 Pro to a Bluetooth device.

Turn off Bluetooth

You cannot turn off Bluetooth however, Bluetooth will turn off after about two minutes after you turn the power on unless the S1 Pro successfully connects to a Bluetooth device.

When you turn on the power on the S1 Pro, it will attempt to connect to a paired device via Bluetooth. If there are no paired device, it will go into pairing mode.

If the S1 Pro cannot connect to a paired device, the Bluetooth light will blink for about two minutes while it is attempting to connect. If it doesn't make a connection, the Bluetooth light will turn off (time out). At that point, the Bluetooth is off until the next time you turn the power off/on.

Disconnect a Bluetooth connection

If you have Bluetooth connection active and you want to disconnect it. If you manually disconnect, the S1 Pro system will time out after about 2 minutes, and Bluetooth will remain off until the next time you power off/on.

IOS

Starting with iOS 9, Apple has added a new option for Bluetooth devices:

  • Open Settings, select Bluetooth
  • Tap the "i" circle button to the right of the accessory.
  • From there, you can see the new "Disconnect" option, alongside the legacy "Forget This Device" choice.
Android

  • From home, tap Apps > Settings > Connections tab > Bluetooth.
  • Tap the ON/OFF slider to turn Bluetooth on.
  • Tap the connected device, and then tap OK to disconnect.

Reconnect a Bluetooth Connection after a time out

If the S1 Pro system Bluetooth light is off (because it has timed out), if you press it briefly, it will blink.

With the Bluetooth light blinking, I've been able to initiate a Bluetooth connection from a previously paired device. This worked with:

  • An IOS 11.4 device
  • An Android 7.0 device
  • A Windows 10 device


Checking the Battery Level

To check the battery, turn on the S1 Pro (switch in the top position). Wait until the power light is steady blue. Double tap the Bluetooth button (tap tap in under a second). Count how many times the power light blinks before returning to steady blue.

NOTE If you are running your S1 Pro System and battery LED turns solid red - the battery is nearly out of power. Connect to AC power to keep the show going.

Bass Content in Bluetooth

How can I reduce the bass in Bluetooth music
The S1 Pro System reproduces the audio received over Bluetooth. To change the EQ use an app in the Bluetooth source device.
See IOS Equalizer
See Bass over excursion... Community discussion
Will Bose issue a firmware update to change the bass response in Bluetooth content?
We tested the S1 Pro system with a wide range of applications including live music, music playback with various styles of music, public speaking, and more. We tuned the bass response for the best overall performance for the widest number of people. We continue to listen to customer comments here and through all channels. We know that most of our customers are extremely happy with the sound of the S1 Pro system.
We have explored ways to change the response in the low frequencies. We found making the S1 Pro system more tolerant of heavy bass diminishes the overall performance in other ways. We don't have plans to change the sound profile of the S1 Pro system through a firmware update. Source

S1 Pro System Bass Distortion with Bluetooth through Channel 3

There have been some discussions in the Bose Portable PA Community about bass distortion with Bluetooth sources through Channel 3. Will Bose issue a firmware update to fix this?
If you hear bass distortion you're hitting the maximum volume (bass) the S1 Pro system can handle. We tested the S1 Pro system with a wide range of applications including live music, music playback with various styles of music, public speaking, and more. We tuned the bass response for the best overall performance for the widest number of people. We continue to listen to customer comments here and through all channels. We know that most of our customers are extremely happy with the sound of the S1 Pro system.
If you need more overall volume for music playback you need a bigger enclosure. The L1 Compact and the larger L1 systems may be a better choice.

FAQs

S1 Pro system FAQ

What makes the Bose S1 Pro multi-position 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 and ToneMatch processing onboard, 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 optional 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 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, the performer 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.

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 drop-off of sound levels than the smaller array found in the S1 Pro.

Is the S1 Pro multi-position PA system designed for Mobile DJ’s?

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 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 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 1/8” (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 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. It does however ship with a slip cover for normal transport.

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 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 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 drop-off 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 maximizing the benefits of my system? Please visit the Bose Pro Portable PA Community
