The goal was quite simple: design an all-inclusive product that offers a complete inte- gration of all of the elements required to achieve state-of-the-art loudspeaker manage- ment. This design goal was reached and exceeded with introduction of the DriveRack® series. The 481 DriveRack® includes all of the functionality and features of the 480 DriveRack®. The 481 incorporates 4 inputs and 8 outputs using Euroblock connectors. The 481 DriveRack® also has a streamlined front panel which makes it ideal for per- manent install applications. All programming functions of the 481 DriveRack® can be performed through a 480 master, the 480R, or via the Windows GUI. By using the DriveRack® network system, up to 99 DriveRack® units can be chained together.

The 481 DriveRack® continues the legacy DriveRack® series, which has been created by the company that has been redefining the standard of signal processing for more than 30 years. dbx® Professional Products has created a product that caters to numerous applications in tour sound and sound contractor requirements.

The 481 DriveRack® was designed with the purpose and vision of providing four independent input and eight output channels of processing power that include 31- Band Graphic equalizers, as well as dbx’s own industry standard dynamics process- ing. All aspects of the aforementioned features can be controlled by the included dbx Professional Products Interactive DriveWare™ software. Software updates can also be downloaded instantly from www.dbxpro.com through the RS 232 port.

481 DriveRack specifications

The dbx Pro 481 DriveRack is a powerful audio processing tool designed for professional sound engineers and musicians seeking to enhance their live sound and recording setups. This versatile device serves multiple purposes, including equalization, dynamics processing, and feedback elimination, making it an essential component for both live performance and studio applications.

One of the standout features of the dbx Pro 481 is its advanced automatic feedback suppression technology. This feature uses sophisticated algorithms to detect and eliminate feedback before it becomes a problem, allowing for a smooth and uninterrupted audio experience. This capability is invaluable in live settings where feedback can disrupt performances.

The DriveRack also includes a comprehensive equalization system, providing users with up to 31-band graphic EQ capabilities. The equalizer allows for precise control over frequency response, enabling sound engineers to tailor the audio output to fit the acoustic characteristics of the space. With its intuitive interface, users can easily adjust the EQ settings to ensure that the sound meets their desired specifications.

Another notable characteristic of the dbx Pro 481 is its digital signal processing (DSP) capabilities. The built-in DSP allows for high-quality signal manipulation with low latency, ensuring that the audio remains clear and natural. This feature is particularly beneficial when applying compression, limiting, and other dynamic processing techniques, as it eliminates the sonic artifacts often associated with lower-quality processors.

Additionally, the dbx Pro 481 features a user-friendly LCD screen that provides real-time feedback on various parameters, making it easy to monitor and adjust settings on the fly. The intuitive layout allows users to navigate through its various functions seamlessly, ensuring that they can focus on their performance rather than the equipment.

The device also offers multiple input and output options, facilitating integration with various audio systems. This flexibility ensures that it can be used in a wide range of applications, from small venues to large-scale events.

In summary, the dbx Pro 481 DriveRack integrates advanced feedback suppression, comprehensive equalization, powerful DSP capabilities, and a user-friendly interface into a single device. Its versatility and performance make it a go-to choice for audio professionals aiming to achieve top-notch sound quality in any environment.
