The C18 is equipped with an ultra-low noise oscillator.\n\n\n\n\n\nOCXO 10MHz\nThe oscillator used here is a 10MHz OCXO, designed to promote a constant temperature and thus minimize changes in output frequency caused by temperature variation. Specially designed for audio, it allows you to achieve a greater level of detail, a more realistic sound signature and a higher dynamic range.\n\n\n\n\n\nIndependent Output Stage\nThe output circuit of the C18 maintains and does not deteriorate the low phase noise signal provided by the main oscillator. The GDRV-P1 can also provide both a sine and a square wave signal to accommodate different devices.\n\n\n\n\n\nDiscrete Power Supply\nThe C18 features a discrete Class A power supply circuit that is highly efficient, providing low ripple and fast response.\n\n\n\n\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_1_5abba96c-85e3-4adf-bc9b-541da5055f46.jpg?v=1662019660","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_3_b27cec82-0d6f-47ba-9301-f90812e541fd.jpg?v=1662019751","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_2_89ac083b-fbfb-4d6e-941c-e3d43435c423.jpg?v=1662019751","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_4_a09c0a3d-cc58-47f2-9c64-44fbb9ac0a10.jpg?v=1662019681","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_5_7614fb37-1fee-4207-a82f-8233800e790e.jpg?v=1662019689","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_6_a42c74d5-5e83-425b-82f1-3c60f00d8487.jpg?v=1662019694"],"price":1599.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:47.293Z"},"share_url":"https://firestarter.network/l/lst_4zAmCw53","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
