Ladder Boya is a new digital interface that provides precise audio signal processing thanks to FEMTO Clock technology and DSD512/PCM768kHz support.
The device is based on a modern AMR STM32F466 microcontroller, which works in conjunction with FPGA for buffering and restoring a digital signal. The LADDER technology used allows you to isolate and stabilize the USB input, and a low-jitter crystal generator improves signal transmission to an external DAC. Connection via USB 2.0 Type B makes working with a PC convenient, and the use of Boya DDC significantly improves the sound quality when playing from a computer.
