The ADC2 was designed for recording situations where there is no room for compromises. Every detail in its intricate circuitry serves to perfectly capture every nuance of the incoming audio and maintain the signal’s integrity all the way to your recording medium. Whether the input comes from microphones or line-level sources, the ADC2 is the choice for recordings that are meant to last forever.
CAPTURE EVERYTHING
Use the ADC2 to record live music on location or in a studio, with microphones connected to the unit’s two high-end microphone preamps. Or use the line inputs to capture the stereo output of an analog mixing or mastering desk — or to digitize analog tapes for remastering or archival purposes. Whatever the input source, the ADC2 will capture every detail without compromise or coloration.
PURIST SIGNAL PATH
The ADC2 uses state-of-the-art A/D chips in our proven Correlation Technique configuration. Every audio channel uses two converter channels which reduces converter imperfections. The analog input stages are kept balanced from the input connectors all the way to the converter chips. The input levels are controlled by a relay attenuator circuit with 1 dB steps, for perfect matching between the channels and easy, accurate recall. The built-in peak limiter guarantees that clipping can never occur.
OUTPUT AND METERING
The output formats are AES/EBU in one or two-wire technique, S/PDIF in single-wire as well as Firewire for a direct connection to computers. The Firewire connection can also be used to feed a signal from the computer to the S/PDIF output of the ADC2. A large bar graph shows input and output levels, overload conditions, and the gain reduction in the aforementioned peak limiter.
