DriveRack 4800/4820 Family

Applications

STEREO FOH w/ SUBS ON AN AUX

As the centerpiece of this system, the DriveRack 4800

provides all the Signal Routing and Processing needed.

With Speaker Processing elements including: Bandpass

and Crossover Filters with up to 48 dB/Octave slopes,

Output Parametric EQ, Delay and Limiting, DriveRack

provides everything necessary to make the speakers per-

form their best. The 4800 also offers system-wide EQ with

both an Input Parametric EQ for the House or System

while also providing an Input Graphic EQ for the Front

of House Engineer. Additional processing is also available

including Noise Gating, Notch Filtering, or classic dbx

Compression that can be linked across all the input chan-

nels or Feedback Suppression. The DriveRack 4800 is a

complete solution for this high-powered system.

STEREO FOH w/ SUBS & MONITORS

The DriveRack 4800 is perfect for this very common

application where a single console is feeding both the ste-

reo Front of House system as well as a couple of Monitor

mixes. With the enormous amount of processing power

that the DriveRack offers there is plenty of EQ for both

systems; the System Technician or Contractor can have a

House Parametric EQ that is set then locked away while

the Engineer uses the Input Graphic EQs for the Stereo

FOH and the Monitors. The Monitors would also benefit

from the use of our Feedback Suppression algorithm that

can pinpoint feedback frequencies down to 1/100

of a

Hertz.

LCR w/ EXT . ROOM & AUX ZONES

The flexibility of the DriveRack 4820 is showcased in this

system that uses three inputs from the console to create an

LCR plus Sub system. The send to the subwoofer could

be an additional input from the console, or it could just

be an output that is receiving a signal summed from the

combination of the LCR inputs. The Extension Room

likewise uses an internal sub-mix to create quasi-stereo

or mono with a Delay. The Auxiliary Zones are mono

sends created using the Mid-Mixer in the 4820. Each of

these sub-systems benefits from the DriveRack's wealth

of processing. Wall panel control adds simple elegance; in

the main system this ZC-3 wall panel is recalling presets,

while the panels in the other areas are providing local

volume control.
