The Bryston BUC-1 USB Converter provides a high resolution, ultra low jitter, digital audio signal interface between your USB source (Laptop, Desktop, Notebook etc.) and audio device. It utilizes a single USB cable and allows for native 24 bit resolution at sampling rates of up to 192 kHz. The BUC-1 is built upon low phase noise clocks, to run as the master audio clock, resulting in extraordinarily low jitter output. The goal of any quality USB converter is to convey the exact bits in the audio signal, with the least amount of ‘jitter’ possible, and the BUC-1 accomplishes this goal with exceptional performance.

The Bryston BUC-1 Converter allows for native 24 bit resolution at sampling rates up to 192 kHz. The Bryston USB Converter is built upon low phase noise clocks inside the Bryston USB Converter to run as the master audio clock, resulting in extraordinarily low jitter output. Digital Outputs include AES/EBU, BNC and COAX. High quality output transformers isolated the output signal from any computer noise.
The goal of any quality USB converter is to convey the exact bits in the audio signal, with the least amount of ‘jitter’ possible. Most USB Converter devices are capable of delivering the correct bits. However, the timing is a different matter. Timing errors in the signal can come from a number of different sources: noisy power supplies or clocks, timing errors already present on the audio signal being encoded, and noise in the transmission line, just to name a few.
Most crucially, the Bryston USB Converter controls the master timing of the audio system. So, rather than the computer (Laptop) running the master clock, and the audio device slaving to this, the main system clock is in the Bryston USB Converter, and the rest of the system slaves to it.The last feature, which is frequently referred to by the technical name “asynchronous” (as opposed to “isochronous”), is the key to obtaining ultra-low jitter on USB devices. With asynchronous USB receivers, the jitter is essentially limited only by the clocks on the audio device, plus any [typically very small] timing errors from additional logic gates that the clock signal must travel through.
