Use

Switching on
The BoomBoom 100 does not start connecting to your devices if these are already switched on. Therefore, it is advisable to switch on the BoomBoom 100 first, followed by the previously connected devices.

Re-pairing
Previously paired Bluetooth devices connect automatically with the BoomBoom 100 when switched on.

Adjusting the volume
The BoomBoom 100 is a passive transmitter or receiver and does not have volume settings. The desired volume level must be set on the devices that are paired with the BoomBoom 100.

Removing paired devices
To remove previously paired devices from memory, please follow these steps:
Ensure that the BoomBoom 100 is switched on in RX or TX mode. Slide the multifunctional switch (2) all the way to the right (BT) for 6 seconds.
The LED will first flash red/blue and then turns red/blue constantly.

Low volume level.

In TX mode: check the volume on both your Bluetooth headphones and your TV, as both may be able to adjust the volume.

In RX mode: check the volume of your smartphone and the app you are using. Also check the volume of your audio system.
I connected my BoomBoom 100 to the headphone jack of the TV and use my TV’s USB port to power the BoomBoom 100, but I hear a ‘buzz’ in the audio.
Please use a USB adapter to power the BoomBoom 100, or use your TV’s Toslink connector. In your TV’s settings, please ensure that Toslink is set to PCM Stereo.

Poor audio quality and/or audio stutter.

1. To achieve the most low-noise audio possible, set the volume on your audio source to the highest possible level. Then adjust the volume to the desired level on your headphones.
2. Please ensure that you are within range of your Bluetooth device.
3. Bluetooth devices are susceptible to interference from other Bluetooth devices, cordless phones, routers, microwaves and wireless devices operating on the 2.4 GHz band. Please eliminate as many potential sources of interference as possible while using your Bluetooth headphones/speakers.

Audio has a delay (latency)

1. Bluetooth is a digital wireless signal and you can expect some delay due to, for example, the required encryption/decoding and compression/decompression steps.
2. The aptX and aptX Low Latency audio codecs supported by the BoomBoom 100 ensure a much smaller delay compared to regular Bluetooth audio. AptX Low Latency is not even noticeable (<40ms).
3. Use the BoomBoom 100 with a pair of headphones that supports aptX or aptX Low Latency such as the BoomBoom 577.
4. Some modern TVs and receivers also have an audio delay option. To minimise delay, please ensure that the audio delay is set to 0.

What is SBC?

SBC (Low Complexity Subband Coding) enables you to wirelessly listen to audio with reasonable sound quality. SBC is the standard method to send audio via Bluetooth.

What is AAC?

AAC (Advanced Audio Coding) enables you to wirelessly listen to CD-quality audio. This codec is, for example, used by Apple in their iPhones and iPads. However, the audio delay is much greater than with aptX or aptX Low Latency and about 120ms +/-30ms.

What is aptX?

AptX® enables you to wirelessly listen to CD quality audio. When your device is equipped with aptX, it is no longer necessary to use the entire bandwidth to transmit music via Bluetooth. A Bluetooth connection is a sort of data pipeline between different devices. This pipeline only has a maximum width and therefore it can sometimes be difficult to send large music files through it. AptX solves this problem by reducing the size of the music files being sent wirelessly via Bluetooth. The files can be sent through the wireless pipeline without affecting the quality of the files. This allows you to use aptX to listen to CD quality music anytime, anywhere. The BoomBoom 100’s green LED will start to flash slowly with an aptX connection.

What is xptX Low Latency?

aptX Low Latency ensures a very short audio delay of less than 40 ms. With a regular Bluetooth connection, this is more than 100 ms. Both the transmitter and the receiver must have aptX Low Latency to be able to use this feature. With the BoomBoom 55, 77, 93 and 100, the LED lights up green to indicate an aptX Low Latency connection.
