• Stability at 2 Ohms: Designed to safely handle low impedance loads, making it compatible with a wide range of speaker configurations.
• Comprehensive Protection: Equipped with protection circuits against short circuits, overload and overheating, plus a soft-start function to protect components when turning it on.
• Control and Flexibility: Features stereo, parallel, and bridged operating modes. Includes an adjustable crossover (45-960 Hz / 450-9600 Hz) with switchable high-pass and low-pass filters for advanced frequency management.
• Advanced Monitoring: A blue LCD screen displays critical information such as temperature, operating mode, and signal level. Each channel has LED indicators for signal, overload (clip), and bridge mode.
• Professional Sound Quality: With a high damping factor (Damping Factor >500) and a high response speed (Slew Rate of 60V/uS), it guarantees accurate bass reproduction and a clear transient response.
• Robust Construction: Mounted on a 2U chassis suitable for 19-inch rack mounting, it is designed for transport and heavy use on tours, by mobile DJs and in permanent installations.

Product benefits

The PDA-B2500 is designed for audio professionals who demand the highest standards. Its high power output and ability to handle low-impedance loads make it the perfect engine for large-format PA systems. Sound engineers and technicians will appreciate the comprehensive protection features and clear monitoring, which ensure reliable and safe operation event after event. The inclusion of a built-in crossover and automatic clip limiter simplifies system setup, reducing the need for external processors and ensuring that the sound remains clean and distortion-free, even at high volumes.

Use cases

This amplifier is the ideal choice for a wide range of professional applications. Its power and robust construction make it perfect for providing sound reinforcement at outdoor concerts and festivals, where sustained high sound pressure levels are required. It is also an excellent solution for permanent installations in nightclubs, concert halls, and theaters, where reliability and audio quality are paramount. Mobile DJs and sound rental companies will benefit from its rugged construction and flexibility to accommodate different speaker configurations, from full-range systems to setups with dedicated subwoofers.

Frequently Asked Questions

Can I connect speakers of different impedances?
Yes, the amplifier is very versatile. It's stable at 2, 4, and 8 ohms in stereo mode, and at 4 and 8 ohms in bridged mode. Always check the power specifications for each impedance to ensure optimal performance.

What is the "Ground Lift" function?
The "Ground Lift" function helps eliminate hum or ground loop noise that can occur when connecting different audio equipment together. It's a useful tool for troubleshooting noise problems in complex sound systems.

Do I need an external audio processor with this amplifier?
Although an external processor can always be used for more detailed equalization, the PDA-B2500 includes an adjustable 2-way crossover and high/low pass filters, allowing the signal to be split to feed subwoofers and full-range speakers without the need for an external crossover.

What type of output connectors does it use?
It uses industry-standard NL-4 output connectors (compatible with Speakon), which provide a secure and reliable connection for speaker wires.
