domain. The dynamics program settings are stored in the dynamics library.
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 02R contains a high-performance four-band, fully parametric EQ. Each
input channel, tape and effect return, and the stereo output channel
features an EQ. You can tailor the EQ 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.
EQ settings can be stored and recalled using scene memories, and can be
adjusted in real-time with the dynamic automix system. The 02R also has
an extensive EQ library which allows you to store frequently used EQ
settings for instant recall. An EQ program stored in the EQ library is a good
starting point and reference when making adjustments to the EQ.
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 Part 2
(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.
