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.
