W A R N I N G : TO REDUCE THE RISK OF FIRE OR ELECTRIC￿ SHOCK DO NOT EXPOSE THIS EQUIPMENT TO RAIN OR MOISTURE

The symbols shown above are internationally accepted symbols that warn of potential hazards with electrical products. The lightning flash with arrowpoint in an equilateral triangle means that there are dangerous voltages present within the unit. The exclamation point in an equilateral triangle indicates that it is nec- essary for the user to refer to the ownerÕs manual.

These symbols warn that there are no user serviceable parts inside the unit. Do not open the unit. Do not attempt to service the unit yourself. Refer all ser- vicing to qualified personnel. Opening the chassis for any reason will void the manufacturerÕs warranty. Do not get the unit wet. If liquid is spilled on the unit, shut it off immediately and take it to a dealer for service. Disconnect the unit during storms to prevent damage.

WARNING

FOR YOUR PROTECTION, PLEASE READ THE FOLLOWING:

WATER AND MOISTURE: Appliance should not be used near water (e.g. near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc). Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings.

POWER SOURCES: The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance.

GROUNDING OR POLARIZATION: Precautions should be taken so that the ground- ing or polarization means of an appliance is not defeated.

POWER CORD PROTECTION: Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.

SERVICING: To reduce the risk of fire or electric shock, the user should not attempt to service the appliance beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel.

FOR UNITS EQUIPPED WITH EXTERNALLY ACCESSIBLE FUSE RECEPTACLE:

Replace fuse with same type and rating only.

U.K. MAINS PLUG WARNING

262 specifications

The DBX Pro 262 is a highly regarded professional audio processor that excels in delivering versatile signal processing capabilities. Designed for both live sound and studio environments, the Pro 262 combines high-quality dynamics processing, filtering, and precision mastering features, making it a powerful tool for audio engineers and producers.

One of the standout features of the DBX Pro 262 is its dual-channel design, allowing users to process two different audio signals independently. This makes the device particularly well-suited for a variety of applications, from live concerts to studio recordings. Each channel is equipped with a comprehensive set of controls, including threshold, ratio, attack, release, and gain make-up, allowing for precise dynamic control over the audio signals.

The Pro 262 employs advanced VCA (Voltage Controlled Amplifier) technology, which delivers transparent compression without colorizing the audio. This technology is crucial for maintaining the integrity of the original sound while ensuring that levels are controlled efficiently. Additionally, the unit features a peak limiter that safeguards against unwanted distortion by preventing signals from exceeding a set threshold.

Another notable characteristic of the DBX Pro 262 is its inclusion of a full parametric equalizer. The EQ section provides users with up to 12 bands of adjustable frequency bands, enabling detailed shaping of the audio signal. This precision EQ allows for effective problem-solving in both live performance and studio mixing environments.

In terms of connectivity, the Pro 262 comes with balanced XLR inputs and outputs, ensuring that the signal integrity is maintained throughout the audio chain. It also features a sidechain input, which allows users to set up external control for dynamic processing based on different input signals.

The unit is designed with an intuitive, user-friendly interface that allows engineers to make quick adjustments during live performances. LED meters provide real-time feedback on levels and gain reduction, ensuring that users can monitor performance at a glance.

Overall, the DBX Pro 262 is not just a versatile processor; it is a reliable tool that brings professional-grade dynamics processing and equalization to a wide range of audio applications. Its cutting-edge technologies make it a must-have for any audio professional seeking to elevate their sound quality and creative expression.
