XTA DP 448 processor for Sale | 4-In / 8-Out, Fully Working

The XTA DP 448 processor for sale is a professional 4-input / 8-output digital loudspeaker management processor designed for demanding touring, live sound and fixed-installation applications. These XTA processors are perfectly working, with all batteries confirmed OK, and worldwide shipping is available.

With four inputs, eight independently configurable outputs, 96 kHz processing, extensive EQ, crossover control, delay and professional limiting, the DP448 provides a powerful central processing platform for complex PA systems.

XTA DP 448 processor – Product Details

4 Inputs / 8 Outputs

The DP448 provides:

4 × Inputs

and

8 × Outputs

This 4-in/8-out architecture provides considerable flexibility for professional system design.

The processor can manage multiple loudspeaker sections and signal paths from one compact rack unit, making it suitable for sophisticated stereo and multi-zone configurations.

Perfectly Working XTA Processors

These units are specifically described as:

Perfectly Working

This makes them suitable for buyers looking for operational professional processing equipment rather than units requiring repair or restoration.

For used touring equipment, functional condition is particularly important because the processor may sit at the heart of the loudspeaker management chain.

All Batteries Are OK

The internal batteries have also been confirmed as:

All OK

This is an important detail for buyers considering older professional digital processors.

The listing should highlight this alongside the working condition so buyers know the battery status has been checked.

96 kHz Professional DSP

The DP448 uses a high-resolution DSP architecture operating at:

96 kHz

with 24-bit conversion.

The processing platform provides the precision required for detailed system alignment while maintaining professional audio performance.

It is designed to handle crossover, EQ, delay, gain and limiting without requiring multiple separate processing devices.

Flexible Input-to-Output Routing

The DP448’s routing architecture allows the four input channels to be distributed across its eight outputs according to the required system design.

This makes it suitable for configurations involving:

• Main left/right
• Subwoofers
• Bass sections
• Mid/high sections
• Front fills
• Delay speakers
• Side fills
• Additional venue zones

A system engineer can therefore create a configuration specifically suited to the loudspeaker and amplifier inventory.

Extensive Input Equalization

Each input provides comprehensive EQ capabilities.

Processing includes graphic and parametric equalization for detailed system tuning.

This can be used for:

Overall system voicing

Venue-response correction

Frequency shaping

Problem-frequency correction

and

Input-specific optimization.

Independent Output Processing

Each of the eight outputs can be individually configured.

Output processing includes:

Parametric EQ

High-Pass & Low-Pass Filtering

Delay

Gain

Polarity

Mute

Limiting

This makes the DP448 particularly useful for systems where each loudspeaker section requires different processing.

Professional Crossover Management

The DP448 can function as a sophisticated multi-way crossover.

Available filter families include professional crossover types such as:

Butterworth

Bessel

and

Linkwitz-Riley

with slopes reaching up to approximately:

48 dB per Octave

This provides substantial flexibility for configuring different loudspeaker systems.

Precision Delay & Alignment

Independent delay processing enables accurate time alignment between different loudspeaker components and physical locations.

Typical applications include aligning:

Subwoofers with main speakers

Individual driver sections

Front fills

Delay towers

Balcony speakers

and

Distributed venue systems.

Accurate delay settings should ideally be established through professional acoustic measurement.

D-Max Limiting & Speaker Protection

The DP448 incorporates XTA’s professional limiting architecture, including:

D-Max

alongside individual output limiters.

When correctly configured, the limiter system helps prevent excessive signal levels from reaching connected amplifiers and loudspeakers.

Thresholds should always be matched to the actual amplifier gain and loudspeaker specifications.

Excellent for Multi-Way Systems

With eight processed outputs available, one DP448 can manage substantial multi-way configurations.

For example, outputs can potentially be allocated to:

Sub-bass

Bass

Low-mid

Mid

High-frequency

Fills

and other system sections.

The exact configuration remains fully dependent on the connected equipment.

AudioCore Remote Control

The processor can be managed using compatible XTA control software.

Remote control is particularly useful when multiple processors are installed in professional racks because engineers can access system parameters without manually navigating each unit.

Settings such as:

EQ

Crossovers

Delay

Limiters

Gain

and

Routing

can be managed as part of the system configuration.

Compact 1U Rackmount Format

Despite its extensive processing capability, the XTA DP448 occupies only:

1U

in a standard 19-inch professional equipment rack.

Approximate dimensions are:

482 mm wide

305 mm deep

44 mm high

with an approximate net weight of:

3.5 kg

This makes it highly practical for both touring racks and fixed installations.

Ideal Professional Applications

The XTA DP448 is suitable for:

• Touring PA systems
• Festivals
• Concert production
• Nightclubs
• Theatres
• Live music venues
• Professional rental companies
• Large fixed installations
• Multi-way speaker systems
• Delay systems
• Front-fill management
• Monitor systems
• Professional system racks

Its combination of eight outputs and detailed DSP makes it especially useful where a basic 2-in/4-out processor would not provide enough channels.

Useful with Professional Amplifier Systems

The DP448 can be integrated into systems using professional amplifiers from manufacturers such as Powersoft, Lab Gruppen, MC² Audio, Full Fat Audio and other touring-grade platforms.

It can also manage systems using professional loudspeakers from different manufacturers, provided the correct crossover, EQ and protection parameters are configured.

Worldwide Shipping Available

Shipping is available worldwide.

International professional audio buyers can therefore inquire about delivery to their country.

The final shipping charge should be calculated according to destination, quantity and packaging requirements.

Condition Summary

No price, flightcase or additional accessories were specified, so these should not be advertised as included until confirmed.
