Once again, the industry leader in dynamics

processing has redefined the standard of audio

excellence for which all others are certain to follow.

The dbx is the first studio

mastering tool that offers sampling rates up to

96kHz, with a true 48 bit digital signal path, as well as

the legendary dbx dynamics processing which has

been the industry forerunner for more than 25 years.

The dbx Quantum’s intuitive operating system allows

you convenient access to the most powerful

mastering tool ever produced. The patent-pending

dbx Conversion System allows you to

retain the warmth and body of the analog signal,

while adding punch, depth and focus. By utilizing dbx’s

proprietary Tape Saturation Emulation, the

dbx Quantum retains the original warmth of analog

recording, while delivering the digital clarity and

versatility required in today’s digital world of music

production and mastering. The dbx Quantum also

offers dbx’s patented dynamics processing in a 4 band

multiband system. The 4 way crossover splits the

signal into 4 bands which then may be individually

gated, compressed, and limited. This uncompromising

quality and flexibility combined, make the dbx

Quantum the ideal tool of choice for any

recording application.
