【 】Made with sandblasted, black anodized aluminum featuring precise laser markings. Internally, it’s composed of a composite of OPA1612+OPA1656, Viking resistors, Murata and Samsung C0G capacitors, and quality connectors/relays sourced from Taiwan.
【 】Ultra-low THD+N variable gain buffer tailored for Cosmos ADC. 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.
【 】The 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.
【 】 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.
