Understanding Your Bose S1 Pro’s Connectivity Options
Before diving into the connection process, it’s essential to understand the various connectivity options available on your Bose S1 Pro speakers. Knowing these options will allow you to choose the best method for your specific needs and equipment.
Exploring Input And Output Ports
The Bose S1 Pro features a versatile selection of input and output ports, designed to accommodate a range of audio sources and configurations. Let’s take a closer look at each one:
- Channel 1 & 2 Inputs: These are combo XLR/TRS jacks, meaning they can accept both XLR (balanced) and 1/4-inch TRS (balanced or unbalanced) connectors. These channels are typically used for microphones, instruments (like guitars or keyboards), or other line-level audio sources. Using balanced cables (XLR or TRS) is generally recommended for longer cable runs to minimize noise and interference.
- Channel 3 Input: This channel features a 3.5mm (1/8-inch) auxiliary input for connecting smartphones, tablets, laptops, or other devices with a headphone output.
- Bluetooth Connectivity: The S1 Pro offers convenient Bluetooth connectivity, allowing you to wirelessly stream audio from your smartphone, tablet, or other Bluetooth-enabled devices.
- Line Output: This is a 1/4-inch TRS output that allows you to send the audio signal from your S1 Pro to another device, such as another S1 Pro, a mixer, or a recording interface. This is the key to connecting two S1 Pros for stereo or dual-mono sound.
Mono Vs. Stereo: Choosing The Right Configuration
When connecting two Bose S1 Pro speakers, you’ll need to decide whether you want to run them in mono or stereo. Understanding the difference is crucial for achieving the desired sound.
- Mono: In a mono configuration, both speakers output the same audio signal. This is ideal for situations where you want to distribute the sound evenly across a wide area, such as for presentations, solo performances, or small gatherings. Mono is also simpler to set up, as you only need to send one signal to both speakers.
- Stereo: In a stereo configuration, each speaker outputs a different channel of the audio signal (left and right). This creates a wider, more immersive soundstage, allowing listeners to perceive the spatial separation of different instruments and sounds. Stereo is ideal for music playback, DJ sets, or any situation where you want to create a more dynamic and engaging listening experience.
Connecting Two S1 Pro Speakers: Step-by-Step Guide
Now that you understand the basics, let’s get down to the business of connecting your two Bose S1 Pro speakers. We’ll cover the two most common methods: using the line output and using Bluetooth.
Method 1: Using The Line Output For Wired Connection
This is the most reliable method for connecting two S1 Pros, especially in situations where you need a stable connection and minimal latency.
- Step 1: Gather Your Equipment. You’ll need two Bose S1 Pro speakers, an audio source (e.g., a mixer, smartphone, laptop), and a 1/4-inch TRS cable (also known as a balanced cable). The length of the cable will depend on the distance between your speakers.
- Step 2: Connect the Audio Source. Connect your audio source to one of the S1 Pro speakers (the “master” speaker). You can use the XLR/TRS input on Channel 1 or 2 for microphones or instruments, the 3.5mm input on Channel 3 for smartphones or laptops, or Bluetooth for wireless streaming.
- Step 3: Connect the Line Output. Connect one end of the 1/4-inch TRS cable to the Line Output of the master S1 Pro.
- Step 4: Connect to the Second S1 Pro. Connect the other end of the 1/4-inch TRS cable to the XLR/TRS input on Channel 1 or 2 of the second S1 Pro (the “slave” speaker).
- Step 5: Set the Levels. Adjust the volume levels on both S1 Pro speakers to achieve the desired balance and overall loudness. Make sure the input gain on the slave speaker is appropriately set to avoid clipping or distortion.
- Step 6: Configure for Mono or Stereo. If you want a mono setup, ensure the audio source is sending a mono signal. If you want a stereo setup, you’ll need a mixer or audio interface that can split the audio into left and right channels. Connect the left channel output of your mixer to the master S1 Pro and the right channel output to the slave S1 Pro.
Method 2: Using Bluetooth For Wireless Connection
While not officially supported for true stereo pairing by Bose, there are some workarounds to use Bluetooth to transmit signal to one S1 Pro, and then daisy-chain the signal to a second speaker. This method is generally not recommended for professional applications as you may experience latency and potentially some sound quality degradation. However, in some simple scenarios, it can get the job done.
- Step 1: Pair the First S1 Pro. Put your first S1 Pro (the “master” speaker) into Bluetooth pairing mode. Then, on your Bluetooth device, select the S1 Pro to pair with.
- Step 2: Play Audio. Send the audio signal via Bluetooth from the device to the master S1 Pro.
- Step 3: Connect to the Second S1 Pro via Line Out. Using a 1/4″ TRS cable, connect the master S1 Pro’s Line Out to Channel 1 or 2 of the second S1 Pro (the “slave” speaker).
- Step 4: Adjust Levels. Adjust the volume level on the Bluetooth-connected S1 Pro and the wired S1 Pro to balance the sound.
Important Note on Latency: Bluetooth connections can introduce latency (delay) between the audio source and the speakers. This can be particularly noticeable when using two speakers, as the slight delay between them can create a phasing effect. This is why using a wired connection is always preferred.
Optimizing Sound Quality And Performance
Connecting two Bose S1 Pro speakers is only the first step. To truly maximize your audio experience, you need to optimize the sound quality and performance.
Placement And Positioning
The placement of your speakers plays a crucial role in how the sound is perceived. Consider the following:
- Distance: The distance between the speakers and the listeners should be consistent to ensure a balanced sound.
- Height: Elevating the speakers on stands can improve sound dispersion and prevent the sound from being absorbed by furniture or other obstacles.
- Angle: Angling the speakers slightly inwards can help to focus the sound and create a more immersive listening experience.
- Room Acoustics: Be aware of the room’s acoustics. Hard surfaces can reflect sound, creating echoes and reverberation. Soft surfaces can absorb sound, making the sound dull. Experiment with different speaker placements to find the optimal position for your room.
Understanding The ToneMatch Feature
The Bose S1 Pro features a built-in ToneMatch feature that optimizes the sound for different instruments and microphones.
- Channel 1 & 2 ToneMatch Presets: Each channel has a switch to select different ToneMatch presets. These presets are designed to enhance the sound of specific instruments and microphones. Experiment with different presets to find the one that sounds best for your audio source.
- Using the ToneMatch App: For even more control, you can use the Bose ToneMatch app (available for iOS and Android) to customize the ToneMatch presets. This allows you to fine-tune the sound to your exact preferences.
Using A Mixer For Advanced Control
For more advanced control over your audio, consider using a mixer. A mixer allows you to:
- Control Individual Channel Levels: Adjust the volume of each audio source independently.
- EQ and Tone Shaping: Fine-tune the tonal balance of each channel using EQ controls.
- Effects Processing: Add effects such as reverb, delay, and chorus to enhance the sound.
- Stereo Imaging: Create a wider, more immersive stereo image by panning the audio signals between the left and right speakers.
Troubleshooting Common Issues
Even with careful setup, you may encounter some issues when connecting two Bose S1 Pro speakers. Here are some common problems and how to solve them:
- No Sound from One Speaker: Check the cable connections, volume levels, and input gain settings on both speakers. Make sure the slave speaker is turned on and that the input selector is set to the correct input.
- Distorted Sound: Reduce the input gain on the affected channel. Make sure the audio source is not sending a signal that is too loud. Check for damaged cables.
- Hum or Buzzing: Use balanced cables (XLR or TRS) to minimize noise and interference. Ensure that all equipment is properly grounded. Try plugging the speakers into different power outlets.
- Bluetooth Connectivity Issues: Make sure Bluetooth is enabled on your device and that the S1 Pro is in pairing mode. Move closer to the speaker to improve the Bluetooth signal. Try restarting your Bluetooth device and the S1 Pro. If the Bluetooth connection is dropping out, switch to a wired connection.
- Latency Issues: Use a wired connection instead of Bluetooth to minimize latency. Close any unnecessary applications on your device that may be using processing power.

Whether you’re a musician, DJ, presenter, or simply someone who loves great sound, connecting two S1 Pros is an investment that will pay off in spades. Remember, wired connections are always preferable for reliability and sound quality. So, go ahead, connect your S1 Pros and unleash the power of two!
Can I Connect Two Bose S1 Pro Speakers Wirelessly For True Stereo Sound?
Unfortunately, the Bose S1 Pro does not support true wireless stereo pairing between two units out of the box. While you can connect them using wired connections, direct Bluetooth pairing for left and right channel separation isn’t a feature the S1 Pro offers. This limitation stems from its design primarily as a standalone, portable PA system rather than a specifically designed stereo speaker system.
To achieve a wider, more immersive sound, you could use a mixer with Bluetooth capabilities. Connect your audio source via Bluetooth to the mixer, then route the left and right outputs of the mixer to each S1 Pro speaker individually. This setup, while requiring a separate mixer, would effectively provide a stereo sound experience using two S1 Pro units.
What Cables Do I Need To Connect Two Bose S1 Pro Speakers Together?
The most common method for connecting two Bose S1 Pro speakers is using XLR cables. You will need at least one XLR cable, preferably two if you wish to send a dedicated left and right signal. These cables are essential for transmitting balanced audio signals, reducing noise and interference, especially over longer distances.
Alternatively, you can use 1/4-inch TRS cables (balanced) or 1/4-inch TS cables (unbalanced). However, XLR cables are generally preferred for their superior noise rejection. Ensure the cables you use are of good quality to avoid signal degradation and maintain optimal audio fidelity.
How Do I Daisy-chain Two Bose S1 Pro Speakers?
Daisy-chaining involves connecting one S1 Pro speaker to another in a series. Connect your audio source to the first S1 Pro’s input channel. Then, using the first speaker’s “Line Out” or “Mix Out” output, connect it to the input channel of the second S1 Pro speaker.
This method essentially duplicates the signal from the first speaker to the second. All controls on the first S1 Pro will affect the sound output from both speakers, meaning level adjustments need to be done carefully to maintain a balanced sound between the two units. Keep cable lengths as short as possible to minimise signal loss.
Can I Connect A Subwoofer To One Or Both Of My Bose S1 Pro Speakers?
Yes, you can absolutely connect a subwoofer to enhance the bass response of your Bose S1 Pro setup. The S1 Pro features a “Line Out” or “Mix Out” output, which you can use to send the full-range signal to a subwoofer with its own built-in crossover. This allows the subwoofer to handle the lower frequencies, freeing up the S1 Pro speakers to focus on the mid and high ranges.
For optimal sound, connect the “Line Out” of one S1 Pro to the input of the subwoofer. You can then adjust the crossover frequency on the subwoofer to blend seamlessly with the S1 Pro. Alternatively, if you are running two S1 Pro speakers, you could connect the “Line Out” from a mixer (if you’re using one) to the subwoofer for a more controlled and balanced low-end response.
What Is The Best Way To Control The Volume Of Both Bose S1 Pro Speakers When They Are Connected?
The ideal way to control the volume of both speakers depends on your connection method. If you are daisy-chaining them using the “Line Out” of the first speaker to the input of the second, then the volume control on the first speaker will essentially control the overall volume of both. However, this provides limited independent control over each speaker.
A mixer is the preferred method for controlling the volume of each S1 Pro individually. Connect your audio source to the mixer, and then connect the left and right outputs of the mixer to the individual inputs of each S1 Pro speaker. The mixer allows you to independently adjust the volume, EQ, and other settings for each speaker, providing maximum control over your sound.
What Are The Potential Limitations Of Connecting Two Bose S1 Pro Speakers?
One limitation is that connecting two S1 Pro speakers, especially via daisy-chaining, doesn’t provide true stereo separation. While you get increased volume and coverage, the same signal is essentially being duplicated. For a true stereo image, a separate mixer or audio interface is required to send distinct left and right signals to each speaker.
Another limitation relates to power distribution, especially when running on battery power. Connecting two speakers increases the overall power consumption, potentially reducing the battery life of each unit, especially if they are both running on battery. Consider using AC power whenever possible for extended use.
Can I Use The Bose Connect App To Control Two Connected S1 Pro Speakers Simultaneously?
The Bose Connect app is primarily designed for managing individual Bluetooth connections and settings for single devices. Unfortunately, the app does not offer the functionality to simultaneously control two connected S1 Pro speakers for volume, EQ, or other settings. The app treats each S1 Pro as a separate device.
Therefore, if you require simultaneous control over multiple S1 Pro units, particularly for volume and EQ, you will need to rely on a physical mixer or other external control device. The app is helpful for initial Bluetooth pairing and basic settings, but for synchronized control, a mixer is the superior option.
