Any input can be routed to any output or combination of outputs, making the processor ideal for:

• multi-way loudspeaker systems
• delay towers
• monitor routing
• distributed speaker systems
• subwoofer management
• zone-based installations

This flexibility is especially important in large venues and touring applications where multiple loudspeaker zones require independent processing and alignment.

Advanced Input Processing Tools

Each input channel provides extensive DSP functionality for detailed tonal shaping and system optimization.

Input processing features include:

• 28-band graphic EQ
• 8 parametric EQ bands
• multiple filter response types
• notch filtering
• shelving filters
• all-pass filters
• elliptic filtering
• variable Q adjustment
• phase adjustment in 2° increments

This level of processing allows engineers to precisely optimize source material and room interaction before routing signals into output processing chains.

Experienced system engineers understand that detailed input processing is critical for achieving balanced system performance in difficult acoustic environments.

Powerful Output DSP & Crossover Management

Each of the six output channels includes advanced loudspeaker management functionality such as:

• up to 9 parametric EQ bands
• crossover filtering
• output gain adjustment
• polarity switching

• up to 48 dB/octave filter configurations

Available crossover curve types include:

• Butterworth
• Bessel
• Linkwitz-Riley

This level of flexibility allows the DP446 to integrate with virtually any professional loudspeaker system configuration.

Precision Delay Alignment & Phase Accuracy

The XTA DP446 provides extremely accurate delay management with:

• maximum delay up to 650 ms
• ultra-fine 0.325 µs resolution

Precise delay alignment is essential for:

• subwoofer integration
• line array timing
• front-fill alignment
• delay tower synchronization
• monitor systems
• distributed loudspeaker zones

Even small timing inconsistencies can negatively impact phase coherence and system intelligibility.

The DP446 allows engineers to achieve extremely accurate loudspeaker timing relationships across complex sound systems.
