Pronomic XA-1400 Power Amp 2x 3000 Watt

The Pronomic XA-Series Power Amps are designed for uncompromising continuous use in professional sound systems!

The XA series excels in every aspect. Absolutely dry, crystal-clear, and powerful sound, excellent workmanship, reliable protection circuits, generous cooling system, and high power supply reserves are just some of the qualities that make this power amp the first choice for demanding musicians as well as for tough touring in professional rental.

All essential protection circuits are naturally integrated:

• The power soft-start function prevents overloading the power grid when switching on the amplifier
• The output DC protection constantly checks for DC components at the speaker outputs and switches off the outputs if poor signals occur. This reliably prevents damage to speaker coils from excessive DC components.
• The integrated, barely audible clip limiter reliably prevents amplifier overload. It also prevents DC components from forming in the circuit.
• The sophisticated thermal monitoring and fan control ensure smooth continuous operation under heavy loads.
• The "Noise Free On Off" circuit prevents turn-on and turn-off noises, e.g., during power outages
• Standard protection circuits like short-circuit protection are a matter of course and naturally included.
• All protection circuits constantly check if the fault persists and immediately re-enable the outputs once the fault is cleared.

Advanced Power Supply Design

In analog power amps, the power supply design is extremely important. Therefore, the X-series power supply is uncompromisingly dimensioned:

• The entire power supply design is symmetrical, effectively suppressing RF interference from outside. This is the only way to achieve the excellent signal-to-noise ratio of 103 dB. Even on very large, loud systems, no background noise from the amps is audible.
• The additional input voltage HF filter further eliminates residual ripple in the power supply.
• The integrated multi-stage power management reduces load on the power grid at lower volumes. This ensures safe operation even with poor power supply, e.g., at smaller gigs. This circuit also optimizes heat generation in the amplifier.
• The power supply is generously dimensioned to allow absolutely perfect playback on both channels at full power continuously. For example, when used with powerful subwoofers, this guarantees the best possible performance.

Maintenance-Friendly and Durable Circuit Design

The meticulously thought-out design ensures smooth operation for many years:

• The cooling channels are completely separated from the electronics, preventing unnecessary dust from being sucked into the circuit. This guarantees reliable cooling even during long operation in extremely dusty environments.
• The cooling channels are acoustically optimized to keep the amplifier's self-noise as low as possible. Of course, the fans are controlled by temperature sensors.
• All power connections are excellently soldered, wired, and generally oversized. This greatly increases the lifespan of thermally stressed components.
• The centrally installed toroidal transformer ensures even weight distribution. It is mounted extremely solidly to suppress transformer vibrations.
