Key Feature Discussion
Configuration
The 03D provides a total of 26 inputs (including 8 digital inputs), stereo output (analog
or digital), 4 bus outs, 4 aux sends, 2 internal effects sends, and 8 assignable digital out-
puts via a single YGDAI (Yamaha General Digital Audio Interface) slot. Each input
channel features four-band parametric EQ and a dynamics processor. Input channels 1
to 8 feature balanced XLR and phone jack connections, with individually switched
phantom power. Inputs 1 and 2 feature analog inserts. Input delays can be used for
microphone-placement compensation, while output delays can be used for delay-com-
pensation in multi-speaker systems. The number of inputs can be increased by digitally
cascading two 03Ds together, sharing Bus, Aux, Stereo, and Solo buses. YGDAI digital
inputs and outputs can be configured as bus outs, aux sends, input channel direct outs,
or stereo outs. So although the 03D is a four-bus mixer, assigning the four buses and
four aux sends, or the channel direct outs to the YGDAI slot’s eight outputs allows
eight-track simultaneous recording.

Benefits of a Digital Mixer
You’re probably already familiar with the many benefits offered by digital audio, but
what exactly are the benefits for digital audio mixing? Well, an audio mixer has the job
of combining audio signals from various sources, at differing levels and impedances,
usually into a stereo mix. And it must do this without introducing any new distortions
and noise. Analog mixers do a pretty good job, but even with the best designs, nonlinear
effects caused by circuit components are unavoidable.

and noise. 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 binary numbers
that represent audio signals. The DSP (Digital Signal Processor) chips used for these
calculations never get their sums wrong. So once past the initial A/D conversion, audio
signals are immune from signal degradation. With the 03D, noise, distortion, and
crosstalk are virtually eliminated. You’ll hear a new clarity in your mixes.

Once in the digital domain, it makes sense to keep audio data digital, as multiple
AD/DA conversions can degrade signal quality. With the optional YGDAI interface
cards, the 03D can be connected directly to a modular digital multitrack recorder,
thereby keeping audio data in the digital domain for both recording and mixing. The
final stereo mix can be transferred to a two-track digital recorder using the 03D’s
AES/EBU or Coaxial digital output.

Onboard digital effects and dynamics processors mean that signals remain in the digital
domain, eliminating unnecessary AD/DA conversion. Signal processing is performed
by third-generation Yamaha DSPs, as used in the Yamaha ProR3 Digital Reverberator.

03D Sonic Performance
The 03D’s linear 20-bit 64-times oversampling A/D converters provide a typical
dynamic range of 105 dB. The 03D can generate the industry standard sampling rates
of 44.1 kHz and 48 kHz, or synchronize to an external wordclock source from 32 kHz
–6% to 48 kHz +6%. The stereo output and monitor output feature 20-bit 8-times
oversampling D/A converters, while the aux sends and bus outs feature 18-bit 8-times
oversampling D/A converters. Oversampling techniques effectively increase the inter-
nal sampling rate, so side effects caused by steep low-pass filters, which are used to filter
out sampling frequency components during D/A conversion, are virtually eliminated.
Consequently, audio signal integrity is maintained from input through to output.
