Power House - is here, OVP, 12 Houres of use.
KANN ALPHA, the third product in the KANN series of Digital Audio Players.
While the goal of the Astell&Kern KANN line is to provide ultra high power output to drive any headphone or IEM,
KANN ALPHA has not forgotten the essence of being a portable DAP,
so you can enjoy a near-perfect sound experience wherever you are.
The first Astell&Kern DAP to feature a 4.4mm balanced output
Complete separation of balanced lines to provide noise-free output
Crosstalk of 141dB and top-notch audio performance through a complete circuit redesign
Powerful 12Vrms ultra-high output support
14 ½ hours of continuous playback
Equipped with the latest version of Bluetooth, Bluetooth 5.0
Artistic design and ultra-precision metal shaping technology that Astell&Kern has perfected
First A&K DAP to Feature 4.4mm Balanced Output Port,
Completely Noise-Free
The newly introduced feature of the 4.4mm balanced output port is exciting, however, the most important part is how we implemented it.
Unlike other manufacturer’s products, KANN ALPHA has physically separated the 2.5mm and 4.4mm outputs using micro relays.
When 2.5mm and 4.4mm structures that are connected only to the mute circuit they do not prevent noise interference
that may occur because each signal is not properly blocked.
KANN ALPHA boasts noise-free output because we built in an independent structure that completely blocks
interference from outputs that are not being used and to be switched off therefore preventing the noise from occurring.
Gold PVD Coating Method
In order to minimize contact noise from the output,
a gold PVD coating method is applied to the headphone connector instead of the typical rings used by other products.
This improves both design and function.
By adopting NDICS' Pentaconn 4.4mm connector,
KANN ALPHA not only satisfies the requests of users, but the implementation boasts excellent quality and durability.
Powerful 12Vrms Output
With 14 ½ Hours of Continuous
Playback
KANN ALPHA supports the same powerful 12Vrms output as the existing
KANN CUBE, however the player has been optimized to be more compact.
This is achieved through the miniaturization of numerous parts such as resistors
and capacitors, by rearranging various components and through circuit optimization.
This resulted in the modification of more than 60 parts during the development process.
Ultra-small tantalum capacitors, which were developed exclusively for Astell&Kern
through a collaboration with Matsuo Electric in Japan to meet our high performance
requirements, supply stable power to the player and suppress electrical noise.
This redesigned power circuit used in KANN ALPHA also allows us to achieve
14 ½ hours of continuous playback.
