High-precision, feedback-free design
DC-coupled design with flat frequency response from DC to 1 MHz
As the first in our custom product lineup, the 1-input, 4-output distributor "ACS-8101" has been completed. This product functions to split a single signal into four outputs and features feedback-free discrete buffers, with four circuits for both the left and right channels, for a total of eight circuits. Each circuit operates independently, preventing any interference or leakage between circuits and ensuring pure signal transmission.

Additionally, this buffer employs a DC-coupled design without coupling capacitors, providing a flat frequency response from DC to 1 MHz. It can drive connected cables efficiently without increasing time constants in the low range, minimizing impact on sound quality. The ACS-8101 buffer avoids output reduction common in typical buffer circuits and, thanks to its feedback-free design with accuracy exceeding four digits, keeps DC offset below 1 mV.

The unit is powered by 5V DC, 0.7A, allowing use with USB power sources or mobile batteries. With a gain close to 1 and wideband frequency characteristics, it is ideal for precise audio comparisons or bi-amp connections. The ACS-8101 was developed to facilitate smooth amplifier comparisons, enabling faithful signal distribution while eliminating the hassle of swapping cables.
The ACS-8101 is the optimal choice for professional audio environments to distribute signals accurately while preserving sound quality and achieving high-precision music playback.
