10 Introduction to the 02R
Digital Recording Console 02R Getting Started Guide
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.
