Internally, it's composed of a composite of OPA1612+OPA1656, Viking resistors, Murata and Samsung C0G capacitors, and quality connectors\/relays sourced from Taiwan.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eInput Capabilities\u003c\/h3\u003e\n\u003cp\u003e2 channels balanced with impedance of 200\/100kOhm (bal\/unbal). Accepts a 3.5mm jack with up to 20\/10Vrms (bal\/unbal). Unique MONO mode: When only the left input is utilized, the signal automatically routes to the right channel as well. Moreover, the Cosmos APU's short cables are seamlessly compatible with the Scaler.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eOutput Proficiency\u003c\/h3\u003e\n\u003cp\u003e2 channels balanced with impedance of 20\/10hm (bal\/unbal). 3.5mm jack support with up to 20\/10Vrms (bal\/unbal). The Cosmos APU's short cables are equally fit for Scaler's output. Variable Gain Table: This device comes with 16 positions that can be adjusted using its knob. Ranges from 0db to 26.078db. Notably, in the \"Auto\" position, the Scaler acts as an ultra-fast autoranger (100mS) with the left channel targeting 4.5Vrms. Only the 20Hz-20kHz range is valid for the autoranger.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eFrequency Response\u003c\/h3\u003e\n\u003cp\u003eThe Scaler exhibits a remarkable frequency response of .2Hz-570kHz @ 26db gain +.5\/-3db. It can stretch up to .2Hz-7.11MHz @ 0db gain, although this heavily depends on the cable's capacitance. It's stable up to 7m of mic cable.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eResidual Noise\u003c\/h3\u003e\n\u003cp\u003eA minimal noise footprint of 250nVrms(A) @ 26db gain.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eDistortions\u003c\/h3\u003e\n\u003cp\u003ePrecise measurements are challenging due to the immense loop gain OPA1612+OPA1656 composite. However, estimates suggest it's about 100 times lesser than the Cosmos ADC or H3, sitting at around -175db@1kHz at 0db gain.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eCrosstalk\u003c\/h3\u003e\n\u003cp\u003eDemonstrates exceptional crosstalk performance with L-\u0026gt;R at -133db and R-\u0026gt;L at -158db@1kHz when unused input is shorted at 0db gain.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"E1DA","offers":[{"title":"Default Title","offer_id":68211155239216,"sku":"E1DA-Cosmos-Scaler","price":129.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/6528\/0304\/files\/1_96c79c1d-41b2-4d0a-ad19-5155f62f7aa3.jpg?v=1793308728","url":"https:\/\/homezorvella.shop\/products\/e1da-cosmos-scaler","provider":"Avelisse","version":"1.0","type":"link"}
