Vonyx VXA-2000 II - 2x 1000W PA Power Amplifier
The Vonyx VXA-2000 II is a high-performance stereo power amplifier designed to deliver reliability and powerful sound in professional audio installations. With a 2 x 1000W output, this amplifier is a versatile and affordable solution for mobile DJs, venue sound management, and stage setups requiring a robust power boost. Its robust construction incorporates advanced Surface Mount Technology (SMT) , which not only optimizes internal component space but also ensures superior thermal and mechanical stability, drastically reducing the risk of failure during transport or heavy use.
This "II" version has been refined to provide a wide and natural frequency response while maintaining an exceptionally low noise level. Thanks to its intelligent design, the VXA-2000 II allows for seamless integration into any standard 19-inch rack (occupying 2U in height), facilitating its mounting in flight cases for touring or in fixed control room cabinets. Its front panel offers a clear reading of the equipment's status via signal and peak LED indicators, allowing the sound engineer to monitor performance in real time and avoid unwanted distortion.
Flexibility is one of this amplifier's strengths. It offers both stereo and bridged operating modes, allowing you to combine the power of both channels to drive a passive subwoofer or a high-demand full-range speaker. Furthermore, it incorporates essential safety features such as a ground lift switch to eliminate ground loops and electrical hum, as well as DC output protection, ensuring your speakers are safeguarded against any electrical anomalies.
Main features
-
Versatile power: Capable of delivering up to 2000W in bridged mode (8 Ohms) or 1000W per channel in stereo mode (4 Ohms), adapting to different speaker configurations.
-
SMT Technology: Surface mount circuits that improve durability, signal stability, and vibration resistance.
-
Total connectivity: Flexible inputs via RCA and 6.3mm jack, with multiple output options including locking speaker connectors (compatible with Speakon/NL4), 6.3mm jack and screw terminals.
-
Noise management: Built-in "Ground Lift" switch to isolate the ground and eliminate parasitic noise in environments with complex electrical installations.
-
Visual indicators: Front panel with clip (peak) LEDs for immediate visual monitoring of signal saturation.
Product benefits
The Vonyx VXA-2000 II is designed to make life easier for sound professionals. Its greatest advantage lies in its power-to-portability ratio ; despite its high output capacity, it maintains a manageable weight for easy transport by a single person. The inclusion of multiple output connector types eliminates the need for external adapters, allowing you to connect virtually any speaker cable you have on hand. Furthermore, the reliability of its SMT circuitry ensures the amplifier maintains its performance night after night, minimizing maintenance and maximizing the return on your equipment investment.
Use cases
-
Nightclubs and Clubs: Ideal for amplifying main speaker systems or booth monitors where constant power is required.
-
Mobile DJs: Perfect for mounting on portable racks thanks to its vibration resistance and easy connection at weddings and private events.
-
Bars and Restaurants: Effective solution for high-volume background music or specific dance areas.
-
Small Live and Bands: Excellent as a power stage for floor monitors or to feed the main PA in medium-sized venues.
Frequently Asked Questions
-
Can I connect a subwoofer to this amplifier?
Yes, you can use "Bridge" mode to combine the power of the two channels and power a powerful passive subwoofer, or use one channel for a sub and another for a top if you use an external crossover.
-
Is it compatible with Speakon connectors?
Yes, the NL2/NL4 speaker outputs are compatible with standard 2- and 4-pole Speakon connectors.
-
Does it require special ventilation?
Like any power amplifier, it requires airflow. It is designed for 19" rack mounting, so it is recommended not to obstruct the front or rear ventilation grilles.
-
What does the Ground Lift switch mean?
This switch helps eliminate the "ground" hum that sometimes occurs when multiple audio devices are connected to different power outlets.
