10 Introduction to the 02R Similar to the internal stereo effects, the dynamics processors are patched directly into the signal path while the audio data remains in the digital domain. Signal quality is unaffected by conversion to and from digital as would be the case if you used an external dynamics processor. The dynamics program settings are stored in the dynamics library as well as the scene memory. There are 40 preset programs for you to recall and 88 user programs for you to store your own dynamics programs Parametric EQ with Library The Digital Recording Console 02R contains a high-performance four-band, fully parametric equalizer. Each input channel, tape and effect return, and the stereo output channel features an equalizer. You can tailor the equalization curve with a high degree of precision, covering the entire dynamic spectrum from 21 Hz to 20.1 kHz. Select the center-frequency (F) and adjust the bandwidth (Q) and the gain (G) until you have achieved the perfect sound. The EQ setting for each channel is stored in the scene memory and can be adjusted in real-time with the dynamic automation system. The 02R also has an extensive EQ library which allows you to store frequently used equalizer settings for instant recall. An equalization program stored in the EQ library is a good starting point and reference when making adjustments to the equalization. Digital Benefits You're probably already familiar with the many benefits of digital audio, but what exactly are the benefits for digital audio mixing? An audio mixer has the job of combining audio signals from various sources, at differing levels and impedances, usually into a stereo signal. It must do this without introducing any new distortions and noise. Most analog mixers do a pretty good job, but even with the best designs, nonlinear effects caused by circuit components are unavoidable. In the digital realm, audio mixing consists of adding and multiplying the binary numbers that represent audio signals. The 02R uses a 32-bit DSP (Digital Signal Processor) chip for these calculations, ensuring a very high degree of precision. Once past the analog-to-digital conversion, audio signals are essentially immune from standard signal degradation. With the 02R, noise, distortion, and crosstalk are virtually eliminated. You'll hear a new clarity in your mixes. Once in the digital realm, there's little point converting back to analog. The 02R features stereo digital outputs for direct mixdown to DAT and other digital recorders. It uses the industry standards AES/EBU or IEC958 Part2 (Consumer) for its digital inputs and outputs. With one of the optional digital I/O cards installed in your 02R, you can record direct-to-digital to your modular digital multitrack recorder. Digital Recording Console 02R Getting Started Guide
