Scope of this manual
This document describes the recommended use and care for SOWA and SOWA Pro loudspeakers by SOWA.
SOWA is a wireless loudspeaker system that allows setting up as many speakers as you want, playing the same audio, within a very large area.
The SOWA is for use in the home, and the SOWA Pro is for use at public events, venues and offices.
🚀 Quick start
🖤 The SOWA Product
At SOWA we try to do our part in being as sustainable as possible. We do that by designing our cabinets to minimise the amount of components used, as well as designing with a long product life in mind.
Our speakers are highly modularised and easy to service, meaning that if your product ends up not working, we can easily fix it for you. If your product is out of warranty, we will gladly supply you with the components and help you need to fix a SOWA speaker by yourself. We think that consumers should have the right to repair the products they own.
We sincerely hope that you enjoy your SOWA product for many years into the future. If you have any issues, ideas, or anything in between, please reach out on email@example.com
// Villads, Andreas & The rest of the SOWA Team.
🎛️ User Interface
SOWA Link interface
Stereo channel selection
Audio channels mute
Individual delay setting
The audio inputs of the SOWA are only available during Host and Single Speakers modes. In Join mode, the SOWA will receive any audio that is coming into the connected Host speaker. In other words, any audio sources directly connected to the SOWA in Join mode will not be played. If the SOWA is switched from Join to any of the other modes, playback of analog inputs will be resumed, and Bluetooth connections reconnected.
🎤 Connecting Audio Devices
Connecting a device via Bluetooth
- try toggling off/on the Bluetooth advertisement on the SOWA Speaker, by pressing the Bluetoth Pair button twice.
- Try toggling off/on Bluetooth on the device you are trying to connect to your SOWA.
- Try “forgetting” or deleting the SOWA on your device.
- Try the steps above individually or together. If nothing works, you can try erasing the Paired devices in the SOWA. To perform this clearing of the device-list in the SOWA, press and hold the Bluetooth Pair button until it starts flashing rapidly.
Connecting audio source via AUX (Mini Jack)
The SOWA Speakers are equipped with a 1/8” TRS stereo mini jack port designed for -10 dBV consumer line level signals. This can be plugged into many computers, smartphones, and televisions.
Connecting Microphones or Other Devices (SOWA Pro only)
The SOWA Pro accepts dynamic microphones, as well as line signals from most professional audio equipment.
The XLR output on the SOWA Pro does not provide Phantom power for condenser microphones.
The SOWA Pro is equipped with a balanced mono combo XLR and 1/4” Jack designed for microphone signals or up to +4 dBU pro audio line level signals.
Some equipment, often mixing consoles, may output peaks or signals louder than the common “pro” line level definition of +4 dBu. Consult your equipments user manual to verify correct volume of the equipment you will be using with your SOWA. If your equipment has an output rated higher than the max levels below, we recommend you use a device between the SOWA and the equipment to attenuate the levels appropriately.

Max peak input level allowed (single ended input)

Selecting a Microphone Preset (SOWA Pro only)
When using a microphone, make sure that the Microphone Preset button is set to “Handheld”. This adds a static gain to the input, allowing dynamic microphones to be used. It also adds processing to the XLR input to make most common live-use microphones sound better. The processing used is equalisation, noise gate, compression.
To get the optimal experience using a microphone with your SOWA system, select a high quality microphone with a high sensitivity, for example a Sennheiser e935 or Shure Beta58. Choosing a high sensitivity microphone reduces the noise floor, and increases the output you can get from the microphone.
Muting and Mixing Inputs (SOWA Pro only)
It is possible to mute the inputs on the SOWA Pro. The channel-on/off buttons can be found above the three input types. The buttons lights blue when the input is on. The SOWA Pro can play two inputs in parallel at the same time, mixing the two. The TRS Min Jack and the XLR inputs are exclusive, meaning you can only play through one of them at a time.
When two inputs are on, their signals are mixed directly, meaning there is no side-chaining or bias towards any of the inputs.

▶️ Playback Modes
Play as a single loudspeaker →
Single Speaker mode.
Host audio for other SOWA →
Join another SOWA →
Single Speaker Mode (default)
In Single Speaker Mode, you can use a SOWA as an ordinary Bluetooth or cabled speaker. Simply connect the audio source you want.
This is the default mode of a SOWA speaker, the first time it is turned on. Subsequently, the SOWA starts in whatever mode it was powered down in.
Single Speaker Mode can be recognised by the absence of light in the HOST and JOIN lights of the user interface.
In Single Speaker Mode, it is not possible to select the Left, Right, or Mono audio channels. The SOWA will default to playing the input as mono.
On SOWA Pro, it is also not possible to adjust the Local Volume setting. Only the System Volume knob is available.
Using SOWA Link to Play on Multiple SOWA Speakers
Follow the Quick Start guide to get up and running with SOWA Link in moments.
In Host mode, a SOWA Speaker broadcasts the audio coming in on one if its inputs to as many Join SOWA’s as you want within limitations of range.
To set your SOWA in Host mode, press the Link button to select the role of the SOWA speaker until HOST is lit.
In Join mode, a SOWA Speaker listens to the audio coming from a nearby Hosting SOWA within limitations of range.
To set your SOWA in Join mode, press the Link button to select the role of the SOWA speaker until JOIN is lit.
Selecting stereo channels on a multi-speaker SOWA System
When a SOWA is taking part of a SOWA Link system, either as Host or Join speaker, it can be set to play either the left, right, or a mono sum of the two stereo channels fed either into the Bluetooth input, or the Aux input of the Hosting speaker. The XLR input is per definition mono, and will therefore always transmit equally to SOWA speakers configured as left or right.
Making Independent SOWA Systems with Different Content
Running parallel SOWA Link systems within same area
You can run four separate stereo SOWA Systems simultaneously within range of each other..
To create separate systems, press the Link button (this is called PAIR on early versions of SOWA Pro). The Link button and System Volume knob will start flashing to indicate channel selection. Turn the System Volume knob to select on of the four channels. Repeat this process on all speakers you want to play together.
The SOWA and SOWA Pro are fully battery operated speakers, meaning you can bring them anywhere and not worry about cables for a very long time. The battery in SOWA Speakers is 97 Wh (Watt hours), meaning you can bring it onto most airplanes. Please consult your specific airline for specific or local regulations.
You SOWA should easily play music at 80% volume 20 hours in Host Mode, and can in certain conditions play even longer, or less.
By playing at lower volumes, you can extend the playtime, while playing louder shortens the playtime.
The speaker Hosting a SOWA System will consume slightly more power than the speakers Joining the SOWA system. A speaker in Single Speaker Mode is consuming the least energy of the three available playback modes.
SOWA In Host mode
maximum energy consumption (+20 hours playtime)
SOWA in Join mode
medium energy consumption
SOWA in Single Speaker mode
minimal energy consumption
The ambient temperature also affects the battery life. Colder temperatures reduce the amount of time you can play the SOWA Speaker. Avoid charging your SOWA Speaker at very low temperatures, and avoid exposure to extremely high temperatures during use.
To charge the battery in your SOWA Speaker, plug in the power supply that came with the speaker. The power adapter is 26V 2A DC, and is designed for European 230V mains voltage. Do not use other power supplies other than the one supplied by SOWA. Charging your SOWA from drained state to full battery takes about 4 hours.

📶 Optimising conditions for SOWA Link and Bluetooth
Both SOWA Link and Bluetooth are wireless technologies that depend on a number of factors to work well. Both technologies share the 2,4 GHz radio band with Wifi. Factors that may reduce the wireless range of both SOWA Link and Bluetooth are:
- Number of nearby devices operating on 2,4 GHz (smartphones, laptops, routers, access points, televisions, etc.).
- Obstructions (e.g. walls, people).
If you are experiencing bad connections on either Bluetooth or SOWA Link, you can work with these three factors to regain a proper connection. Reduce the distance between devices, reduce obstacles between devices (ideally enabling them to get free “line of sight” between each other). For SOWA Link in particular, you can also try changing the channel which the SOWA Link system operates on.
The SOWA Speakers are a Class II Bluetooth product, meaning that the Bluetooth range is between you device and the SOWA is rated at 10 meters.
🔨 Taking Care of you SOWA Speaker
Firmware Updating you SOWA Speaker
SOWA and SOWA Pro speakers can be updated with the latest firmware using a Windows application. SOWA can sometimes release new firmware versions with new features or bug fixes.
- On a Windows 10 or 11 computer, download the SOWA Firmware Updater App.
- Install the firmware update app on the computer.
- Power down the SOWA. Then hold the power button on the SOWA until it starts flashing.
- Wait a couple of seconds, then press the Bluetooth button (if it is not already flashing).
- Open the SOWA Firmware Updater App and follow the instructions.
