QUANTUM
Digital Multiband
Processor
The dbx Quantum II is the first studio mastering tool that offers sampling rates up to 96kHz, with
a true 48-bit digital signal path, and the superior dbx dynamics processing that has been making
the hits for 30 years.
Insert the Quantum II into the master outputs of any console or workstation and turn out a professional master every time. The patented dbx dynamics processing is now available in a 4-band
multiband system. The 4-way crossover splits the signal into 4-bands, and each band may be individually gated, compressed, and limited.
The patented dbx TYPE IV™ Conversion System allows you to retain the warmth and body of the
signal, while adding punch and depth. In addition, the intuitive user interface puts all the mastering processes you need right at your fingertips.
The Quantum II’s intuitive operating system allows you easy access to the strongest mastering toolbox ever produced. A quick surf through the menu driven system gives you a glimpse of the packed
feature set. Use the 4 band crossover with independent slope selection to split the incoming signal
into 4 bands that are then each controlled separately for individual gating, compression, and limiting.
The 5-band parametric EQ offers unprecedented control, with variable Q, adaptable or constant Q,
and Lo and High shelving features, making the Quantum II the most versatile and useful tool to use
for any mastering application.
The Quantum II also comes with the patented TYPE IV™ Conversion System. The TYPE IV™ conversion system transfers the character of any analog signal to the digital domain in a way that defies
description. With the help of TSE™ Tape Saturation Emulation, the Quantum II retains the original
warmth of analog recording, while giving it the clarity and versatility we need in today’s digital world
of music production and mastering. You can also dither your signal down to 24, 20, or 16 bits, using
our custom dither algorithms. For more versatility use full MIDI/SysEx control, and internal/external
sync capability. In addition, software upgrades can be downloaded from the dbx website and installed
through the MIDI ports. In addition to these uncomprimising features, the Qauntum II also offers GUI
control and software downloads from www.dbxpro.com.
