user with different modes of functionality including: coarse/fine encoding (successive presses will toggle the knob between a fast and slow mode of operation) and horizontal-vertical navi- gators, which allow the parameter buttons (when used in program and configuration mode) to navigate the program screen horizontally and vertically.

Input Meters

The 480 DriveRack™ provides the user with four independent 12 seg- ment Lightpipe™ input meters that range from -30 to +22 dBu. Note: These meters are calibrated for the +22dBu setting of the gain jumpers.

Threshold Meters

The threshold meters indicate that the threshold level has been exceeded within the dynamics section (compressor/limiter), and gain reduction is taking place within the specific output channel.

Output Meters

The 480 DriveRack™ provides the user with eight independent 12-seg- ment Lightpipe™ output meters that range from -30 to +22 dBu. Note: These meters are calibrated for the +22dBu setting of the gain jumpers.

Output Mutes

The eight output mute buttons are used for independently muting each output on all eight outputs of the 480 DriveRack™.

Power Switch

Turns the 480 DriveRack™ on and off. Note: dbx Professional Products recommends that power amps connected to the DriveRack™, should be powered down prior to cycling the DriveRack™.

1.3 Rear Panel Connections (481)

IEC Power Cord Receptacle

The 481 comes with an International power supply that will accept voltages ranging from 100V- 240V at frequencies from 50Hz-60Hz. An IEC cord is included.

RS485 Control Bus Input (DB-9 connector type)

This input network connection is used to receive information being sent from other units in the DriveRack™ network link.

RS485 Control Thru Bus (DB-9 connector type)

This Thru network connection is used to pass information to other units in the DriveRack™ net- work link.

480 specifications

The dbx Pro 480 is a professional-grade dynamics processor renowned for its versatility and exceptional performance in various audio applications. Designed for both live sound and studio environments, the dbx Pro 480 stands out as an essential tool for sound engineers and musicians alike.

One of the main features of the dbx Pro 480 is its dual-channel operation, which allows users to process two audio signals simultaneously. This functionality makes it particularly advantageous for stereo mixes, providing the ability to manage dynamics across left and right channels cohesively. The unit employs patented dbx OverEasy compression technology. This unique approach to compression allows for smooth transitions between compression and limiting, preventing abrupt changes in audio levels that can disrupt the listening experience. The result is a more musical sound, making it ideal for vocals, instruments, and other dynamic sources.

Additionally, the dbx Pro 480 boasts comprehensive control options, including adjustable ratio, threshold, attack, and release parameters. This level of control enables users to tailor the dynamics processing to fit specific audio material, whether subtle shaping or more aggressive control is required. The inclusion of a high-pass filter on the sidechain input further enhances its versatility, allowing for frequency-dependent dynamics processing that can be particularly useful in managing low-end rumble or controlling sibilance in vocals.

Another notable characteristic of the dbx Pro 480 is its robust build quality, designed to withstand the rigors of both studio and live environments. The device features a rugged metal chassis that protects its internal components while providing reliable performance under various conditions. Additionally, high-quality XLR inputs and outputs ensure that audio signals remain clean and free of interference.

In terms of connectivity, the dbx Pro 480 is equipped with balanced connections to minimize noise and signal degradation, making it suitable for professional setups. Its intuitive front-panel interface includes LED metering for easy monitoring of input and output levels, facilitating prompt adjustments on the fly.

In conclusion, the dbx Pro 480 is a powerful dynamics processor that blends advanced technology with user-friendly features. Its dual-channel processing, unique compression algorithms, and robust build quality make it a top choice for audio professionals seeking to enhance their sound with precision and control. Whether in a recording studio or a live performance setting, the dbx Pro 480 continues to be an invaluable asset in the audio processing landscape.
