AK Recorder


True Recording with Astell&Kern Players, AK Recorder

We at Astell&Kern wanted to go beyond merely listening to music to creating it. With the help of the ultimate technology that is represented in each Astell&Kern player, we envisioned a product beyond any other product available that will fulfill the highest possible synergy.

The AK Recorder is a modular recorder product, designed to be used in combination with any AK300 Series(AK380, AK320 and AK300) product, that delivers live-quality recording and playback of vocals and instrumentals.

This portable, handy recorder offers a wide range of features,
such as DSD 5.6MHz recording (the first of its kind in a portable
recorder), support for professional condenser microphones
through independent phantom power, detailed control of microphones and pre-amplifier Gains, an interface that spans both analog and digital, a digital limiter for professionals, a peak hold, a low cut filter, and support for a number of recording options including pre-recording.

Product Concept
The AK Recorder, which refers to a combination of any AK300 Series device and the Recorder Module, provides you with a whole new level of product. The AK Recorder is a professional recording device that provides you with studio-quality sound, the ultimate goal of all Astell&Kern; products. No matter which AK300 Series product you choose, you will be surprised to find an aesthetically pleasing design and the ability to take advantage of the advanced recording technology in the AK Recorder. Take your first transformational step from music consumer to music producer by combining the AK Recorder with an Astell&Kern; Portable Player. The AK Recorder features professional functions never found before in a portable recorder. The AK Recorder is capable of recording sounds from a variety of sources. You can record live sessions, vocals, instruments and speech, as well as both analog and digital sources by connecting it with other devices.
Wireless Control with Mobile App
No more crouching in front of recording equipment! The AK Recorder supports remote control recording via Wi-Fi. Simply install the free, dedicated application on your smartphone or tablet and you can record as much as you want from the convenience of that device, even if the actual recorder is somewhere else. You can start/stop/pause recording, adjust Gain, view level meters in real-time and access other professional features with just a touch. The application supports up to 4 AK Recorders and of course you can start/stop/pause the recordings of each individual recorder.
DSD Recording
The AK Recorder is the first portable recorder product in the world that supports DSD 5.6MHz recording. While many expensive, professional products typically support up to 24bit/192kHz recording, the AK Recorder provides support for DSD 5.6MHz recording for a proper recording of original sound. With the support of DSD 5.6MHz recording you will be able to record each and every second of a live music recording in DSD 5.6MHz format, the format closest to analog in terms of quality. Just like Astell&Kern; products provide listeners with the ultimate sound quality via DSD playback, using the DSD 5.6MHz recording feature on the AK Recorder you can record the entire live session experience, from the breath of the main vocalist to the sound of air that fills the space in the best sound possible. The goal of Astell&Kern; is to convey sound in a form that is faithful to its source. Now you can record, play and listen to the most faithful sound possible with the AK Recorder.
A Complete Recording Solution
The AK Recorder is a complete recording solution that allows recording via microphones and supports input from both analog and digital sources. Though small in size, the AK Recorder provides 5V/48V phantom power necessary for professional condenser microphones. Support for Mini XLR LINE1 and 3.5mm LINE2 allows you to connect a number of external audio devices with ease. You can connect the phono amplifier of a turntable to record analog LP signals as a perfect digital signal and connect easily with products that have digital-out ports via the AES3(AES/EBU) digital input ports. Furthermore, detailed control of microphones and pre-amplifier Gains are available. Depending on the purpose and environment of each recording, the microphone levels can be increased by 3dB and the pre-amplifier can be increased by 0.5dB using the touch interface. The AK Recorder is suitable for any and all forms of recording, whether it be a performance, a live concert, an interview, a meeting or an analog LP signal.
Advanced Recording Technology
The AK Recorder provides a number of features to give you an easy-to-use system through which to produce the highest possible recording quality. Advanced Compressor/Limiter, Peak Hold, Low Cut Filter and Pre Recording features are all designed to produce a quality recording. During a recording, a loud noise the user is incapable of controlling may be fed into the device. This phenomenon is called "clipping." The AK Recorder's Compressor/Limiter feature prevents clippings. The Compressor/Limiter automatically adjusts any sound level that exceeds a user-defined threshold to prevent sound distortion. As a result, you can rest assured that your recordings will be clipping-free.
Convenient User Interface
Dull black and white displays, a hoard of buttons that you can never fathom the use of without a manual - These are not true for the AK Recorder. A large, touch-enabled display allows you to record conveniently and intuitively. The AK Recorder also provides a Welcome Guide with easy-to-follow, on-screen instructions. The main interface consists of the most frequently used recording features and intuitive graphics that allow you to easily differentiate between analog and digital inputs. Just sliding your finger up or down will adjust the Gain of the microphone and the pre-amplifier; advanced recording options such as Pre Recording and Low Cut Filter can be set all at once. The convenient and easy to use interface lets you enjoy the entire recording process.
Perfect Match
The AK Recorder was designed as an embodiment of the "light and shadow" concept that Astell&Kern; pursues. Its body features light-reflecting surfaces that glisten when exposed to light and produces small sparkles of detail. The same form of the embodiment of light and shadow that is applied to Astell&Kern; Portable Players is also applied to the right side of the AK Recorder to express the continuity of the design. The AK Recorder is designed to function as one unified product. The wheel at the back of the product acts as a physical link between the Astell&Kern; Portable Player and the AK Recorder Module and is a representation of Astell&Kern;'s unique design identity. The AK Recorder is a complete, unified product combining the AK Recorder Module with either the AK380, AK320 or AK300.
Professional-grade AK Stereo MIC Kit
Through our collaboration with DPA(Danish Professional Audio), manufacturer of world-class microphones, we proudly present the AK Stereo MIC Kit. The AK Recorder's AK Stereo MIC Kit comes with DPA's model SC4061 omnidirectional miniature MIC set. The DPA SC4061 MIC is manufactured exclusively at DPA's factory in Asnæs, Denmark. During production, each microphone undergoes scores of testing by highly trained members of our Quality Assurance team and must pass a 15-point function inspection before receiving final approval. The SC4061 MIC can be used to record vocals, musical instruments and interviews. Its SPL(Sound Pressure Level) of 144dB helps produce an optimal recording sound that is free of clipping, even when a loud noise is introduced. The SC4061 MIC's level of quality is proven by the number of studios and sound engineers who use it worldwide.
