ADC1 USB er en to kanals, 24 bit/192kHz analog til digital audio konverter med innebygget USB for tilkobling til at PC eller Mac. På samme måte som DAC1 presser den grensene for konverteringsteknologien samtidig som den ivaretar et akseptabelt prisnivå. Utgangssamplefrekvenser er 44.1, 48, 88.2, 96, 176.4, og 192kHz, og i 24bit. Hovedtilkobling ut er samtidig på XLR, BNC og 192-kHz Toslink. Formatene til utgangssignalene er AES/EBU, S/ PDIF og ADAT. En sekundær utgang gir 44.1 eller 48kHz med valgbar 16 eller 24bit oppløsning. Sølvutgaven leveres uten rackører.

Engage the Music with Benchmark’s ADC1 USB
The barrier between analog and digital should not limit the listening experience. Benchmark’s digital converter technology maintains the sense of musical engagement that was originally present when the sounds were created. The life of the music is never lost in a quagmire of digital artifacts. The depth is never hidden, the image never smeared. Benchmark converters always deliver faithfully, and consistently exceed expectation. The ADC1 USB continues this tradition. The ADC1 USB is a 2-channel 192-kHz 24-bit analog-to-digital audio converter with an unprecedented feature set. This converter was designed to consistently deliver reference quality conversion in ‘real-world’ conditions. It features Benchmark’s jitter-immune UltraLock™ clock system and an extraordinary analog front-end.
Jitter-immune UltraLock™
The UltraLock™ system delivers consistent, high-quality conversion even when slaved to a poor quality external clock. The performance of the ADC1 USB will not degrade when in slave-mode - a claim very few converters can make. Enjoy the convenience of a clock input that automatically recognizes AES/EBU, S/PDIF, Word Clock, or Super Clock sources – all with the unsurpassed jitter immunity of Benchmark’s UltraLock™ clock recovery system.
World-Class Analog Circuitry
The analog front end of the ADC1 USB delivers superior low-noise, low-distortion, high-bandwidth performance over a wide gain range (-6 to +39dB). Precise gain and calibration controls allow for accurate channel matching. The nine-segment, dual-range, digital LED meters enable high-precision level monitoring.
Intelligent Output Options
Two fully-independent auxiliary outputs allow for multiple media and simultaneous back-up recordings. This is extremely helpful when an immediate CD recording or real-time digital transmission is required, while simultaneously providing full-resolution outputs to your primary recording devices. The auxiliary outputs can be operated at independent sample rates and/or bit-depths, or matched to the main outputs.
The ADC1 USB solution provides a native interface, which is capable of streaming up to 96 kHz / 24-bits transparently without requiring special software. This interface is directly compatible with Mac OS X and Windows Vista / XP / 2000.
