{"type":"firestarter.listing","listing":{"id":"lst_xjn0VzEP","product_name":"Matrix SC-1 Audio Grade Reference Clock","category":"Audio Clock","description":"Matrix Audio SC-1 precision clock source\nMatrix Audio proudly presents its first clock source product, meticulously designed for the streamers, DACs and CD players with synchronized reference clock inputs. With outstanding performance, it breathes new life into your audio system, unlocking a new realm of sound quality enhancement. At its core is a 10.000 MHz ultra-low phase noise OCXO module, delivering better than -118 dBc/Hz phase noise at 1 Hz and 20 fs jitter at the output port.\nPrecision OCXO at the core\nAt the core of the SC-1 lies Matrix Audio's custom-made OCXO (Oven-Controlled Crystal Oscillator) module, utilizing an SC-cut crystal. Although this cutting process is highly complex, it enables the clock module with superior phase noise and aging characteristics. With precise temperature control by the oven chamber, the crystal operates in a highly stable environment, effectively minimizing the impact of ambient temperature fluctuations on phase noise and jitter.\nFour independent buffers\nThe SC-1 is equipped with four independent buffered clock outputs, all derived from the same source. While ensuring synchronized output, each output is equipped with its own buffering circuit, providing not only stable output impedance but also excellent driving capabilities. Whether using a single output or multiple outputs simultaneously, it delivers precise and stable performance, meeting your diverse requirements.\n-118dBc ultra-low phase noise\nFor a clock source device, the output noise is closely related to the internal OCXO clock module. However, the actual output noise is not exactly the same as the OCXO output noise, as the output buffering circuit introduces some performance loss. Therefore, phase noise at the output port of the device provides more practical reference value. With the excellent design of SC-1, it achieves ultra-low phase noise of better than -118dBc at 1Hz frequency at the clock output ports, delivering purer, more stable clock signals.\nClear status i","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-matrix-audio-audio-clock-matrix-sc-1-audio-grade-reference-clock-1220554617.png?v=1770841508","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-matrix-audio-audio-clock-matrix-sc-1-audio-grade-reference-clock-1220554616.png?v=1770841448","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-matrix-audio-audio-clock-matrix-sc-1-audio-grade-reference-clock-1220554615.png?v=1770841387","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-matrix-audio-audio-clock-matrix-sc-1-audio-grade-reference-clock-1220554614.png?v=1770841327","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-matrix-audio-audio-clock-matrix-sc-1-audio-grade-reference-clock-1220554613.png?v=1770841268","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-matrix-audio-audio-clock-matrix-sc-1-audio-grade-reference-clock-1220554612.png?v=1770841207","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-matrix-audio-audio-clock-matrix-sc-1-audio-grade-reference-clock-1220554611.png?v=1770841148"],"price":5499,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:56.079Z"},"share_url":"https://firestarter.network/l/lst_xjn0VzEP","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
