The Drawmer D-CLock is a dual input, twenty output word clock distributor with a 16 character blue LCD display providing a high accuracy reference measurement of the incoming sample rate. It uses a high stability TCXO (temperature compensated xtal oscillator) along with a microcontroller to measure the incoming sample rate to an accuracy of 2ppm and displays the information in three different formats, actual frequency (to one decimal place), nominal frequency +\/- ppm error, or nominal frequency plus percentage of pull up or pull down.\u003c\/span\u003e\u003c\/p\u003e \u003cp style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003e \u003c\/span\u003e\u003c\/p\u003e \u003cp style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003eIt has both AES\/EBU and BNC word clock inputs featuring a zero latency loopthrough output with switchable high impedance to maintain the correct level of the digital signal for onward distribution. Sixteen BNC clock outputs are situated on the rear panel with a further four BNC clock outputs on the front panel for quick patching to other digital devices.\u003c\/span\u003e\u003c\/p\u003e \u003cp style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003e \u003c\/span\u003e\u003c\/p\u003e \u003cp style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003eThe wordclock outputs can be fed from the wordclock input at any sample rate between 32KHz and 768KHz or derived from an AES11 input or stripped from an AES3 audio signal at any sample rate between 32KHz and 192KHz. Using an audio signal to provide the clock means even products without a wordclock output, such as some analogue to digital converters, or one of the many mic pre-amplifiers with internal A\/D conversion but no word clock output, can be the master wordclock source for the whole digital studio.\u003c\/span\u003e\u003c\/p\u003e \u003cp style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003e \u003c\/span\u003e\u003c\/p\u003e \u003ch2 style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003eFeatures Include:\u003c\/span\u003e\u003c\/h2\u003e \u003cul class=\"feature\"\u003e \u003cli style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003e2 in x 20 out Clock Measurement and Distribution Amplifier.\u003c\/span\u003e\u003c\/li\u003e \u003cli style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003e16 character blue LCD display providing a reference measurement of the incoming sample rate.\u003c\/span\u003e\u003c\/li\u003e \u003cli style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003eMeasures incoming sample frequencies up to 768 kHz to an accuracy of 2ppm or 2 microseconds.\u003c\/span\u003e\u003c\/li\u003e \u003cli style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003eDisplay modes: ppm, ±ppm \u0026amp; % pull up\/down for video users.\u003c\/span\u003e\u003c\/li\u003e \u003cli style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003eInputs: BNC with zero latency, 33 Ohms impedance.\u003c\/span\u003e\u003c\/li\u003e \u003cli style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003eAES with with zero latency loopthrough.\u003c\/span\u003e\u003c\/li\u003e \u003cli style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003eOutputs: BNC loopthrough \/ AES loopthrough.\u003c\/span\u003e\u003c\/li\u003e \u003cli style=\"text-align: justify;\"\u003e\u003cspan style=\"color: #000000;\"\u003eUniversal voltage filtered mains power input.\u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"Drawmer","offers":[{"title":"Default Title","offer_id":35115060035738,"sku":"D Clock","price":999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0422\/1291\/7402\/products\/DClock_front__86154.jpg?v=1601997751","url":"https:\/\/www.305broadcast.com\/products\/drawmer-d-clock","provider":"305broadcast","version":"1.0","type":"link"}
