2. THE CONCEPT
2.1 The quality of components and circuits
Behringers philosophy guarantees both perfect circuit design and no-compromise selection of components. A
24-bit DSP is used as the heart of the VIRTUALIZER, which is one of the best components available owing to
its outstanding specifications and excellent sonic characteristics. Top-quality 20-bit AD/DA converters ensure
the high-precision conversion of all signals. Additionally, the VIRTUALIZER uses metal-film resistors and
capacitors with very tight tolerances, high-grade switches as well as other select components.
The VIRTUALZER VIRTUALIZER was manufactured using SMD technology (Surface Mounted Device). These
sub-miniature components known from aerospace applications not only guarantee extremely high packing
densities but also increased reliability. Additionally, the VIRTUALIZER was built to meet one of the highest
industrial standards - ISO9000.
2.2 True stereo or stereo effects on a mono input signal?
For maximum performance and flexibility, we have designed our VIRTUALIZER with two independent processing
engines, enabling the following to be achieved:
Dual effects programs, processing two completely different signals with individual mono-effects in
parallel
Parallel processing of two different effects is provided by our dual programs (prg. 25 .. 32) with reverb or echo
on the right channel and chorus, flanger, pitch, tremolo or delay on the left channel.
Multi effects programs process two different stereo effects on a mono summed input signal
In our multi effects (prg. 20 .. 24) the left and right input signals are added and two editable effects are
calculated for a stereo output signal.
Process a stereo input signal with true stereo effects
The delay/echo/flanger/chorus/tremolo and pitch programs (prg. 10,11,17 .. 20) are so called true stereo effects,
which calculate the left and right signals independently. Therefore, the pan position of the input signal has an
impact on the pan position of the effect signal.
Combine all the processing power to implement the extremely elaborate reverb programs
It took us quite some time to determine whether we should also maintain this true stereo feature for our
dedicated reverb algorithms or to provide the maximum processing power for calculating a real virtual acoustic
stereo field from a mono summed input signal. As a result of our analysis of acoustic simulations, it turned out
to be much more realistic and convincing, to compute exact early reflections - the soundwaves which reach the
ear before the diffused reverberation - rather than sacrificing these for true stereo operation. This is one of the
major advantages of our VIRTUALIZER compared to other multieffects units. At last, thanks to the VIRTUALIZER,
the benefits of virtual acoustic simulations are available in a very affordable reverb processor with high class
sound quality.
