Introduction
The Marmitek BoomBoom 100 is a versatile 2-in-1 Bluetooth audio device designed to enhance your audio experience. It functions as both a Bluetooth audio receiver and a Bluetooth audio transmitter. In receiver mode (RX), it allows you to stream music wirelessly from your smartphone, tablet, or computer to your existing audio system (e.g., Hi-Fi, home cinema). In transmitter mode (TX), it enables you to send audio wirelessly from an audio source (e.g., TV, CD player) to Bluetooth headphones or speakers. It supports high-quality audio codecs like AAC, aptX, and aptX Low Latency for superior sound and minimal delay.

- Ensure your audio system is set to the correct input source.
3. Transmitter Mode (TX) Setup
Use this mode to transmit audio from a non-Bluetooth audio source (e.g., TV) to Bluetooth headphones or speakers.
- Set the TX/OFF/RX switch on the BoomBoom 100 to the TX position.
- Connect your audio source to the BoomBoom 100 using one of the following methods:
- Analog Audio: Use the 3.5mm stereo jack cable or the 3.5mm to RCA converter cable. Connect one end to the '3.5mm AUX Audio In' port on the BoomBoom 100 and the other end to an available audio output on your TV or audio source.

Operating
Bluetooth Pairing
After connecting the BoomBoom 100 as described in the Setup section, you need to pair your Bluetooth devices.
- Ensure the BoomBoom 100 is powered on and in the desired mode (RX or TX). The LED indicator will flash, indicating it is in pairing mode.
- On your Bluetooth device (e.g., smartphone, headphones), enable Bluetooth and search for available devices.
- Select "BoomBoom 100" from the list of found devices.
- Once connected, the LED indicator on the BoomBoom 100 will turn solid.
Multipair Party Mode (Connect 2 Headphones)
In transmitter mode (TX), the BoomBoom 100 allows you to connect two Bluetooth headphones simultaneously for shared listening.
- Pair the first pair of Bluetooth headphones as described above.
- Once the first headphones are connected, put the second pair of Bluetooth headphones into pairing mode.
- The BoomBoom 100 will automatically search for and connect to the second pair of headphones.
- Both headphones will now receive audio from the connected source.
Audio Codecs (AAC, aptX, aptX Low Latency)
The BoomBoom 100 supports advanced audio codecs to ensure high-quality sound and minimal latency:
- AAC: Advanced Audio Coding, commonly used by Apple devices, provides efficient compression with good audio quality.
- aptX: A high-quality audio codec that delivers CD-like audio over Bluetooth.
- aptX Low Latency: This codec significantly reduces audio delay, ensuring that audio and video remain synchronized, which is ideal for watching TV or movies. For aptX Low Latency to function, both the transmitter (BoomBoom 100) and the receiving device (e.g., headphones) must support it.
Maintenance
To ensure the longevity and optimal performance of your Marmitek BoomBoom 100, follow these maintenance guidelines:
- Keep the device clean by wiping it with a soft, dry cloth. Avoid using liquid cleaners or solvents.
- Protect the device from moisture, water, and extreme temperatures.
- Do not expose the device to direct sunlight for extended periods.
- Avoid dropping the device or subjecting it to strong impacts.
- Store the device in a cool, dry place when not in use.
Troubleshooting
If you encounter issues with your BoomBoom 100, refer to the following common problems and solutions:
| Problem | Possible Solution |
|---|---|
| No power/Device not turning on | Ensure the USB power cable is securely connected to both the BoomBoom 100 and the power adapter, and the adapter is plugged into a working wall outlet. Try a different USB port or power adapter. |
| Cannot pair Bluetooth device | Make sure the BoomBoom 100 is in the correct mode (RX or TX) and its LED is flashing, indicating pairing mode. Ensure your Bluetooth device is also in pairing mode and within range (typically 10 meters). Turn off and on Bluetooth on your device, or restart both devices. |
| No audio output/input | Verify that all audio cables (3.5mm AUX, Optical) are correctly and securely connected to the appropriate input/output ports on both the BoomBoom 100 and your audio equipment. Check the input selection switch on the BoomBoom 100 (AUX, OPT, BT) and ensure your audio system is set to the correct input source. Adjust volume levels on all connected devices. |
| Audio delay (lip-sync issues) | If experiencing delay in TX mode, ensure both the BoomBoom 100 and your Bluetooth headphones/speakers support aptX Low Latency. If not, some delay may be inherent. |
| Poor audio quality or intermittent connection | Reduce the distance between the BoomBoom 100 and the paired Bluetooth device. Remove any obstacles that might interfere with the Bluetooth signal (e.g., thick walls, large metal objects). Avoid placing the device near other wireless devices that might cause interference. |
