Marketing Information |
Designed to provide incredible
flexibility, sonic excellence and intuitive control for performance
applications, the DriveRack® 4800 is the new flagship of the hugely
successful DriveRack family. From the powerful 96 kHz DSP engine and
standard analog and digital I/O, to the QVGA display and multiple
control surfaces, the 4800 provides all the processing, flexibility and
control necessary for both installation and live use. The menu-based
set-up procedure includes selectable DSP inserts on all inputs and
outputs including classic dbx compression, limiting and advanced
feedback suppression (AFS) among others.
The DriveRack 4800 is the next generation of the famous DriveRack
family, and like its predecessor it is engineered to provide “Everything
you need between the mixer and the power amps”. In keeping with this
philosophy the 4800 includes four inputs and eight outputs with both
analog and digital connectivity. The 96 kHz processing engine is capable
of offering insert processing functions to customize the processing path
for your application, in addition to the standard system processing
functions all with extremely low latency and extended frequency
response. From Signal Routing, EQ, and Bandpass Filters, to classic dbx®
Dynamics and Feedback Suppression all the processing is available and
with the sonic excellence that you would expect from the world's leading
system processing manufacturer. With all this processing power
available, control is of paramount importance. The DriveRack provides a
full color display to speed manual operation; this combined with
intuitive front panel controls, an easy to use GUI and optional wall
panel controllers means that whether your application is tour sound or
installation, the DriveRack 4800 has what it takes. |
