TERATON ALPHA, The Essence of A&K Audio Technologies
Achieving the powerful output for the most detailed headphones and managing the complex signal paths of a dual tube and triple amp system with minimal noise would have been impossible without TERATON ALPHA, AK's Ultimate Sound Solution. Astell&Kern has refined TERATON ALPHA, incorporating insights from the Hybrid Tube System in the SP2000T and the noise reduction advancements from the CA1000.
TERATON ALPHA, developed through extensive research, is Astell&Kern's proprietary technology designed to deliver audio playback as close to the original sound as possible. This is achieved through effective power noise removal, efficient power management, unwavering amplification, and a fully converted audio output interface. The HEXA-Audio Circuitry structure and independent dual audio circuit, first introduced in the SP3000, are integrated with TERATON ALPHA's sound solution to produce the purest and most authentic sound.
4-Levels of Gain and up to 15Vrms Output for the Perfect Head-Fi Setup
To drive the most detailed IEMs and the most demanding headphones perfectly, an output that matches the characteristics of the receiving device is essential. The ACRO CA1000T supports four gain level settings, allowing almost any headphones to operate optimally.
These four gain levels enable users to create the ideal output for their device's characteristics and sound, fine-tuning the volume to their preference. With up to 15Vrms output, the CA1000T effortlessly powers high-impedance headphones.
The electrical capacity of the output ports has been increased to ensure stability when operating devices with different impedances at various gain levels.

Custom Design to Minimize Microphonic Noise
We've designed a special custom solution to reduce microphonic noise caused by external shocks and vibrations. Addressing the inherent structural challenge of vacuum tubes, which can generate noise from even minor shocks or vibrations, we rigorously developed and tested new designs during prototyping.
Each vacuum tube is encased in flexible silicone covers on both sides to absorb shocks, while magnetic force physically isolates it from the PCB. This ensures enhanced stability and isolation during operation. At Astell&Kern, we meticulously refine these intricate details to deliver unmatched audio quality, setting our products apart from the competition.
*A patent application has been made for this technology.
Crossfeed, Speaker Effect When Listening Through Headphones
In a headphone setup where left and right channels are closely separated, extended listening can lead to ear fatigue. Activate Crossfeed to achieve a balanced and comfortable sound experience from the moment it's switched on.
Crossfeed blends portions of the original signal from one channel and routes it to the opposite channel with a time delay, centering the sound image for a more natural listening sensation. Fine-tune your listening experience with precise adjustments like Shelf Cutoff, Shelf Gain, and Mixer Level to personalize the level of crossfeed to suit your preferences.
Optimize Device Care With USB-PD 2.0 Charging and Battery Protection Mode
The ACRO CA1000T supports USB-PD 2.0 charging at 9V/3A, providing up to 11 hours of continuous playback when fully charged. To preserve battery longevity despite prolonged connections to various audio devices, it's essential to manage charging durations effectively.
Equipped with a battery protection mode, the ACRO CA1000T optimizes battery life by limiting charging to 85% capacity initially. If the battery level falls below 80%, it resumes charging back up to 85%, ensuring optimal battery health over time. Enjoy powerful sound with extended battery life, thanks to the ACRO CA1000T's innovative battery protection mode.
*Battery protection mode will be supported through a firmware update.
