Mosconi Pro 4|10-AAB EVO 4 Channel High Performance Amplifier

.

Analog Reference. Engineered for Maximum Sonic Precision.

The MOSCONI PRO 4|10 AAB EVO is a 4-channel amplifier designed for demanding car audio systems where sound quality and control take center stage.

At its core is AAB technology, an amplifier concept fundamentally different from conventional Class AB amplifiers.

Instead of using a shared control stage for all power transistors, the output stage operates with distributed regulation at the component level.

The result is exceptionally stable and linear signal processing, even under real-world conditions such as temperature fluctuations, load variations, or highly dynamic music signals.

AAB Technology: Component-Level Control

• In conventional amplifiers, the entire output stage is controlled through a common operating point.
• This approach assumes that all power transistors behave identically - something that never fully occurs in real-world operation.

.

AAB technology follows a different approach:

• Each individual power transistor is monitored and regulated separately.
• Local control loops ensure that every component remains within its optimal operating range at all times - regardless of:
• temperatures,
• current flow,
• load behavior,
• component tolerances.
• This results in significantly more stable and consistent operation across the entire amplifier stage.

Stability Instead of Compromise.

This distributed architecture reduces typical issues found in conventional amplifiers:

• thermal drift,
• uneven transistor behavior,
• unstable operating points,
• dependency on component tolerances.

Even at high output levels, with complex speaker loads and dynamic music signals, the amplifier remains controlled and predictable.

Separated Signal and Power Paths Create a Clean Foundation for Sound.

The internal architecture consistently separates the sensitive audio signal path from the power supply section.

The power supply handles high currents and rapid load changes.

The signal path, in contrast, operates with extremely small voltages and reacts sensitively to interference.

The clear separation on both layout and grounding level prevents these influences from reaching the audio signal.

This specifically reduces:

• interference caused by current peaks,
• load-induced feedback into the power supply,
• internal crosstalk within the amplifier.
• As a result, the signal remains clean, stable, and uncolored even at high output levels.

As a result, the signal remains clean, stable, and uncolored even at high output levels.

Sound Character: Control and Naturalness

The combination of AAB technology and clean internal architecture ensures stable playback even under real-world conditions.

This becomes especially evident in the following characteristics:

• high detail resolution,
• stable spatial imaging,
• clean microdynamics,
• controlled behavior at high output levels.
• Even under increasing load, the sound remains calm, structured, and transparent.

Performance and Flexibility

Four powerful channels enable versatile system configurations:

• stereo operation,
• active multi-way systems,
• bridged operation for subwoofers.

The PRO 4|10 AAB EVO combines substantial power reserves with precise control over the loudspeaker.

Stability Under Real-World Conditions

The entire architecture is designed to remain stable even outside ideal laboratory conditions.

A high-performance power supply ensures consistent energy delivery, while internal monitoring continuously supervises temperature and operating status.

This allows the amplifier to remain reliable and controlled even under sustained high-load operation.

.

Precise signal adjustment without potentiometers.

Input sensitivity can be adjusted separately for each channel via DIP switches.

This allows for consistent and long-lasting settings without the need for mechanical wear parts.

Adjustments are made in 0.25-volt increments within the range of 1 to 8.75 volts.

Optimized DirectDSP input

The integrated DirectDSP input allows for direct connection to external DSP systems.

Since signal processing in the amplifier is eliminated, the audio signal remains unchanged and low-loss.

This is particularly relevant for fully DSP-based systems.
