The 241 DriveRack™ Complete Equalization and Loudspeaker System from dbx®Professional
Products continues the legacy of excellence for all-inclusive loudspeaker management systems
set by the 480 DriveRack™. Following in the footsteps of its legendary big brother, the 480
DriveRack™, the 241 is the only unit required between the mixing console and poweramps.
With the 241 DriveRack™, you will no longer have to contest with the obstacles presented by
the large and cumbersome loudspeaker management system racks of the past. With the 241
DriveRack’s all-inclusive signal processing combined with its single rack unit chassis design and
affordable price point, the 241 DriveRack™ is an absolute must for any loudspeaker
management application.

From the company that has been redefining the standard of signal processing for more than 25
years, dbx

Professional Products offers a product that provides all aspects of loudspeaker
management. The design of the 241 DriveRack™ Complete Equalization and Loudspeaker
Management System was methodically executed to accommodate the needs of even the most
discriminating user. The 241 offers a 2 input and 4 output XLR and Euroblock input/output
configuration, while being housed in a single rack space chassis.

The 241 has an incredible menu list including: a 31-Band Graphic or 9-Band Parametric Pre EQ
on each input, numerous Crossovers with Butterworth, Bessel, and Linkwitz-Riley types, 2-Band
parametric post EQs and up to one second of delay on all four outputs, Compressor/Limiter and
Post Delay with up to 365 milliseconds of delay and Output Phase compensation. The stream­lined front panel of the 241 protects all programming information from tampering, while all
aspects of the aforementioned features can be controlled by the included DriveWare™ Interactive
software. Software updates can be downloaded instantly from www.dbxpro.com.
