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 is never smeared. Benchmark converters always deliver faithfully and consistently. The ADC1 USB continues Benchmark's tradition of excellence. 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.

FLEXIBLE DIGITAL OUTPUTS


The ADC1 USB has a total of 5 digital outputs (1-XLR, 2-coax, 1-optical, and 1-USB). These can operate simultaneously at up to three independent sample rates. One of the coaxial outputs can be configured for 16-bit TPDF dithered output. This unique flexibility allows simultaneous recording to a CDR, while recording high-resolution to a digital recorder and a DAW. For example the CDR may operate at 44.1/16 while the DAW operates at 88.2/24 while the digital recorder operates at 192/24. Backup and/or reference recordings can be created with ease while high-resolution outputs are fed to primary recording devices. The optical output supports AES or ADAT formats at resolutions up to 192/24. In ADAT mode, high sample rates are supported using SMUX2 and SMUX4.

INTELLIGENT METERS


The nine-segment dual-range, digital LED meters enable high-precision level monitoring. Meter response times are matched to the response of the human eye so that every peak is clearly visible. All metering is fully-digital and is not subject to calibration errors. A peak hold function allows an infinite hold to verify that an over has not occurred. Dual ranges allow signal presence monitoring, or precise headroom indication. The meters even use an upsampling technique to detect and display inter-sample peak overloads. This upsampled metering warns of potential overloads that may not be detected by conventional digital meters.
