Design for life
Sporting Astell&Kern’s recognisable signature angled design, influenced by the reflective interplay of shadow and light, the ACRO BE100 makes a striking design statement that can seamlessly fit into any living space. The triangular shapes on front metal-grille mesh compliments the premium faux leather finish of main unit, while the top aluminium-hewn knurling-patterned knob allows accurate fine tuning of the volume, level-by-level, with a gentle touch.
The area below the volume control illuminates and acts as an indicator, flashing different colours for each mode or volume level, helping users to easily identify the speaker status and control it intuitively.
Declaring its hi-fi sound credentials, the BE100 arrives with an onboard 32-bit high-quality DAC (digital-to-analogue converter). Where most common Bluetooth speakers rely on the limited DAC embedded into the Bluetooth chipset, the BE100’s dedicated DAC is based on the technology from Astell&Kern award-winning portable digital audio players. The separate internal circuitry ensures it has the capabilities to deliver a superior and detailed audio performance beyond its rivals.
To help realise this class-leading sonic performance, the mid/bass driver and 2x tweeters have been custom-built. The 4in mid-bass cone is made from ultra-durable yet lightweight Kevlar fabric to improve response speed and timing and provide a more accurate bass sound. Furthermore, the rear port is installed to extend the speaker’s bass response. The two silk dome tweeters produce crystal clear high-frequencies, while sound-absorbing material inside the wooden cabinet reduces resonance by completely sealing the interior, enabling a full, rich fidelity.
Poorly designed amplifiers can produce clipping sounds at maximum volume. Employing its renowned expertise in amp design technology, Astell&Kern has developed a Class-D amplifier that guarantees consistent sound quality without distortion even at top volume.
The amp’s onboard digital crossover also ensures a clear and precisely timed sound by splitting the audio signal into different frequency range. In addition, dynamic range control (DRC) is used to protect the speaker unit as it hits maximum output power. To minimise jitter – the undesired deviation in time from the transmitted signal – the Bluetooth chipset is equipped with a 50ps clock to enable incredibly accurate sound.
The latest high-definition wireless connectivity options are covered with the ACRO BE100 boasting Bluetooth 5.0, providing greater range and a more stable wireless connection when streaming from a compatible device such as a smartphone, tablet or laptop. Support for 24-bit aptX HD (48khz) and LDAC (96khz) codecs, offers the best possible wireless sound quality.
Elsewhere, music fans can tweak the sound with the onboard five-level treble and bass settings, while a 3.5mm AUX input allows the connection of Astell&Kern’s portable digital audio players and similar devices.
