Mosconi Pro 4|30 AAB EVO

Analog Reference. Engineered for Maximum Sonic Precision.

The MOSCONI PRO 4|30 AAB EVO is a 4-channel amplifier designed for high-end car audio systems where sound quality and control take center stage.

At its core is the AAB technology, an amplifier concept fundamentally different from conventional Class AB amplifiers.
Instead of using a shared control stage for all output 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 variations, load fluctuations, or dynamic music signals.

AAB Technology: Control at Component Level

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

AAB technology follows a different approach:

Each individual output transistor is monitored and regulated separately.
Local control loops ensure that every component always operates within its optimal working range – independent of:

• temperature
• current flow,
• load behavior,
• component tolerances.

This results in significantly more stable and consistent operation of the entire amplifier.

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 highly dynamic music signals, the amplifier remains controlled and predictable.

Separate Signal and Power Paths Create the Foundation for Clean 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, on the other hand, operates with extremely low voltages and is highly sensitive to interference.

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

This specifically reduces:

• interference caused by current peaks,
• load feedback into the power supply,
• internal electromagnetic interference 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 a clean internal architecture ensures stable playback even under real-world operating conditions.

This becomes especially evident in the following characteristics:

• high level of detail resolution,
• stable spatial imaging,
• clean microdynamics,
• controlled behavior at high listening levels.

Even under increasing load, the sound remains calm, structured, and transparent.

Power and Flexibility

Four powerful channels allow for versatile system configurations:

– stereo operation,
– active multi-way systems,

The PRO 4|30 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 current delivery, while the internal monitoring system supervises temperature and operating status.

This allows the amplifier to remain reliable and fully 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.
