Benchmark ADC1 USB - 2-Channel ADC with USB 24-bit 192kHz
The ADC1 USB is a reference-quality, 2- channel, 192-kHz, 24-bit, analog-to-digital converter featuring Benchmark's Advanced USB Audio™ technology, phase-accurate UltraLock™ clock system with multi-function clock input and word clock output, and Benchmark’s 9-segment dual-range digital LED metering.
The ADC1 USB is designed for maximum transparency and is well suited for the most demanding applications in studios and mastering facilities. A rugged and compact half-wide 1 RU enclosure also makes the ADC1 USB an excellent choice for location recording, broadcast facilities, and mobile rigs. The internal power supply supports all international voltages and has generous margins for over and under voltage conditions.
