{"type":"firestarter.listing","listing":{"id":"lst_VZxvbZYL","product_name":"SMSL G1 Master Clock Generator","category":"Audio Clock","description":"\nTiming is everything\n\nAn external master clock that makes timing the foundation of your system. The SMSL G1 locks your digital gear to a single 10 MHz reference so transients are tighter, imaging feels realer, and bass is locked in. An SC-cut OCXO with ±3 ppb accuracy sits under a constant-temperature shield, fed by a low-noise linear supply and four independent buffer stages that drive up to four components at once. Compact, solid, and compatible with CD transports and DACs that accept a 10 MHz input, like SMSL’s own PL200T MQA-CD Transport and PA200 GaN Power Amplifier.\nBring your music in lock step\nDigital audio lives and dies by clock accuracy. The G1 provides a single, steady 10 MHz reference to your DAC, transport, and other digital gear so they agree on when “now” is. Less nanosecond-level jitter means crisper imaging, fewer smeared transients, and low frequencies that stop and start when they should. \n\nSC-cut OCXO for long-term stability\n\nAt the center is an SC-cut oven-controlled crystal oscillator (OCXO) with phase noise measured at −105 dBc/Hz at 1 Hz offset and frequency accuracy within ±3 ppb. In plain terms: drift is tiny and noise is low. It reaches basic thermal stability in about two minutes, and it settles further after roughly ten minutes.\n\nconstant-temperature shield, calmer phase noise\n\nThe OCXO sits inside a dedicated, insulated chamber that evens out micro-temperature swings and blocks external heat sources. Stable temperature equals stable frequency, and it’s one of the simplest ways to keep phase noise down and microdetail intact.\n\nfour 10 MHz outputs with independent buffers\n\nOne clock, four destinations. Each BNC output is driven by its own buffer to hold output impedance steady and handle real-world loads without sag. Run a transport and a DAC in parallel, add a DDC or streamer, and keep everything on the same timeline. Outputs are 3.3 Vpp square wave with selectable 50/75 Ω loading to match the gear on the other end.\n\nlow-noise power wi","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107811.jpg?v=1757449498","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107809.jpg?v=1757449491","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107803.jpg?v=1757449373","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107802.jpg?v=1757449370","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107801.jpg?v=1757449368","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107800.jpg?v=1757449364","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107799.jpg?v=1757449360","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107798.jpg?v=1757449359","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107797.jpg?v=1757449256","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107796.jpg?v=1757449253","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107795.jpg?v=1757449250","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107794.jpg?v=1757449247","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107793.jpg?v=1757449244","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107792.jpg?v=1757449242","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107791.jpg?v=1757449238","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107810.jpg?v=1757449494","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107808.jpg?v=1757449488","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107807.jpg?v=1757449485","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107806.jpg?v=1757449482","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107805.jpg?v=1757449479","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-smsl-external-clock-smsl-g1-master-clock-generator-1192107804.jpg?v=1757449376"],"price":529,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.318Z"},"share_url":"https://firestarter.network/l/lst_VZxvbZYL","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
