Practical info and function information:
USB/SD/Bluetooth player:
The USB/SD card player supports drives up to 32 GB. Compatibility with all brands and types is not
guaranteed as several manufacturers maintain different standards. Larger drives may be supported, but
loading time may increase when storage devices with larger capacity are used.
The standard Bluetooth password is:
1234
Use this password to connect your mobile device to the speaker, to stream audio and music.
Asymmetrical horn dispersion:
The compression driver of the speaker (capable of producing mid-high and high frequencies), is mounted in
a moulded asymmetrical horn. The horn dispersion is wide at the bottom and small at the top. This way, the
sound dispersed on small distance is projected very wide. The dispersion for longer distance is narrow, as
the high frequencies need more coupling to carry them further and provide the complete room with sufficient
sound pressure.
Bass reflex ports:
The bass reflex ports of this speaker have two functions:
- Produce airflow, caused by the woofer. As the woofer is constantly moving, the built up air pressure needs
to be able to enter and exit the cabinet, otherwise the pressure in the cabinet will be too high for the speaker
to move sufficiently (and thus produce less sound pressure). By adding bass reflex ports, more sound
pressure is created and more bass response is created easily.
- Create airflow for cooling. The rear of the speaker, where the amplifier module is located, creates heat
when used for a longer period of time on high volume. The airflow makes sure that sufficient cooling takes
place to cool down the internal components.
Do not block the bass reflex ports as this has a negative influence on your maximum sound pressure level,
the sound quality of the speaker and the internal components.
Built-in mixer:
The built-in mixer on the rear panel is used to control several inputs at the same time. For example, when
you wish to use the Bluetooth connectivity to stream background music and wish to connect a microphone, it
is possible to mix the two input signals with the volume levels for each signal input.
