XTA DP 446 for Sale | 4-In / 6-Out Loudspeaker Management Processor

The XTA DP 446 for sale is a professional 4-input / 6-output digital loudspeaker management processor from XTA’s 4 Series. Designed for touring PA, clubs, theatres, festivals and permanent installations, it combines high-resolution DSP, flexible routing, extensive EQ, crossover filtering, precision delay and professional limiting in a compact 1U rackmount unit.

With four inputs rather than the conventional two-input architecture found on many loudspeaker processors, the DP446 provides additional flexibility for sophisticated multi-way and multi-zone professional sound systems.

XTA DP 446 Technical Specifications

4 Inputs and 6 Outputs

The defining configuration of the DP446 is:

4 × Inputs

combined with:

6 × Outputs

This gives system designers significantly more routing flexibility than a basic stereo crossover.

Multiple source signals can be processed and distributed across different loudspeaker sections, zones or outputs from a single processor.

Flexible Routing Architecture

The DP446 provides flexible signal routing between its inputs and outputs.

This can be useful when configuring:

Main PA systems

Subwoofer feeds

Front fills

Delay speakers

Monitor systems

Separate venue zones

or more complex multi-way loudspeaker configurations.

For professional installations, this flexibility can reduce the number of separate processors required.

96 kHz Processing

The XTA DP446 operates at a native:

96 kHz Sample Rate

with professional 24-bit conversion.

This architecture is designed to provide excellent audio transparency while supporting the extensive filtering, EQ, delay and limiting required for professional loudspeaker management.

The result is a processor suited to systems where both precise control and high audio quality matter.

Extensive Input Processing

Each input provides detailed processing options for system-wide tuning.

The available tools include graphic and parametric equalization, allowing engineers to make both broad tonal adjustments and narrow corrective changes.

This can be useful for:

• System voicing
• Room-response correction
• Feedback control
• Tonal balancing
• Source-specific processing
• Overall system optimization

Powerful Output EQ

Each of the six outputs provides extensive parametric equalization.

This is especially important for multi-way systems because different loudspeaker sections often require individual correction.

For example, separate processing can be applied to:

Subwoofers

Bass sections

Midrange

High-frequency sections

Fills

and

Delay cabinets.

Advanced Crossover Control

The DP446 provides comprehensive crossover filtering with slopes reaching up to approximately:

48 dB per Octave

depending on the selected filter configuration.

Available filter families include commonly used professional options such as:

Butterworth

Bessel

Linkwitz-Riley

This provides considerable flexibility when integrating different loudspeaker components and system sections.

Precision Delay

The processor offers delay of up to approximately:

650 ms

providing substantial scope for professional time alignment.

Delay can be used for:

Driver alignment

Sub-to-top alignment

Delay towers

Distributed loudspeakers

Balcony fills

Front fills

and other physically separated loudspeaker positions.

Phase & Polarity Management

The DP446 provides additional tools for managing the relationship between different loudspeaker sections.

Combined with delay and crossover processing, these functions can help system engineers optimize acoustic summation around crossover regions.

Proper adjustment should be based on system measurement rather than generic settings.

Professional D-Max Limiting

Loudspeaker protection is another important strength of the DP446.

The processor incorporates output limiting together with XTA’s:

D-Max Limiter

The limiter architecture is designed to control excessive signal levels while maintaining professional audio performance.

Correct thresholds should always be configured according to the connected amplifier and loudspeaker specifications.

Independent Output Control

Each output can be individually managed using functions such as:

Gain

Mute

Polarity

Delay

EQ

Crossover filtering

and

Limiting.

This allows each loudspeaker section to receive processing appropriate to its specific role within the system.

Compact 1U Design

Despite its extensive processing capability, the DP446 occupies only:

1U of Rack Space

in a standard 19-inch professional rack.

Approximate physical dimensions are:

482 mm wide

44 mm high

305 mm deep

with a weight of approximately:

3.5 kg

This compact design is particularly useful for touring and rental racks where space and transport weight matter.

Professional Touring Applications

The DP446 is well suited to professional touring environments.

Potential applications include:

• Concert sound
• Touring PA systems
• Festivals
• Live events
• Rental companies
• Theatre productions
• Club systems
• Corporate AV
• Fixed installations
• Multi-zone audio systems

Its four-input architecture can be particularly valuable in systems requiring more complex signal distribution.

Suitable for Multi-Way PA Systems

One DP446 can manage several independently amplified sections of a professional loudspeaker system.

For example, its outputs could be configured for combinations involving:

Sub-bass

Bass

Low-mid

Mid/high

Fills

and other loudspeaker zones.

The exact configuration depends on the loudspeakers, amplifiers and system design.

Professional System Protection

When configured correctly, the DP446 provides a centralized layer of loudspeaker protection.

The combination of:

High-pass filtering

Low-pass filtering

EQ

Gain management

Peak limiting

and

D-Max limiting

allows engineers to establish operating parameters appropriate for the connected loudspeakers.
