Vonyx VXA-3000 - 2x1500W Stereo Bridgeable PA Power Amplifier

Vonyx VXA-3000 - 2x1500W Stereo Bridgeable PA Power Amplifier

The Vonyx VXA-3000 is positioned as a robust and versatile solution within the professional sound amplification range, designed to offer outstanding power performance in both fixed installations and mobile setups. This two-channel amplifier stands out for its ability to deliver a maximum power of 2 x 1500W at 4 Ohms , guaranteeing wide and powerful sound coverage, ideal for keeping the energy high in dance floors, bars, and live events.

The VXA-3000's internal engineering utilizes Surface Mount Technology (SMT) . This manufacturing method not only reduces the weight and size of the components but also dramatically improves circuit stability and long-term reliability, minimizing the risk of failure during intensive use. Thanks to this construction, the amplifier offers an extremely low noise level and a wide frequency response, ensuring that the audio signal remains clean and faithful to the original source.

One of the great strengths of this power amplifier is its configuration flexibility. The user can easily switch between standard stereo mode and bridge mode . In bridge mode, the amplifier combines the power of both channels to deliver up to 3000W at 8 ohms , a perfect feature for powering large passive subwoofers without the need for additional equipment. Furthermore, its standard 19-inch design allows for easy integration into any professional audio rack, occupying only 2U of height.

In terms of connectivity, the Vonyx VXA-3000 is ready for any scenario. It offers inputs via RCA and 6.3 mm jack connectors, facilitating connection to mixing consoles, DJ controllers, or audio interfaces. For speaker output, it provides three options: NL2 connectors (compatible with Speakon), 6.3 mm jacks, and screw terminals (binding posts), allowing the use of virtually any type of speaker cable available.

Main features

• Flexible power: Capable of operating at 2x1500W (4 Ohm) or bridged to deliver 3000W (8 Ohm) on a single mono channel.
• SMT Technology: Surface mount circuits that guarantee greater thermal stability and durability of the equipment.
• Visual indicators: Front panel equipped with signal LEDs, power and "Clip" (peak) indicators to monitor performance and prevent saturation.
• Comprehensive protection: Includes DC output protection and a ground lift switch to eliminate hum caused by ground loops.
• Efficient cooling: Forced ventilation system to maintain optimal operating temperature during long sessions.
• Universal connectivity: Multiple input and output options to accommodate professional and home cables.

Product benefits

The main benefit of the Vonyx VXA-3000 is its excellent power-to-price ratio . It allows mobile DJs, venue owners, and sound engineers to access professional amplification levels without a disproportionate investment. Its ability to operate in "Bridge" mode makes it a two-in-one tool: it can be your main stereo amplifier today and become the dedicated amplifier for your subwoofers tomorrow as your setup grows. Furthermore, the inclusion of a Ground Lift switch solves one of the most common and annoying problems at live events: electrical background noise.

Use cases

• Mobile DJs and Discos: Perfect for powering a pair of 12" or 15" passive speakers at weddings and private parties.
• Installations in Bars and Clubs: Ideal for dance areas that require constant and reliable sound pressure night after night.
• Stage Monitoring: Useful for feeding passive monitor wedges for live musicians.
• Bass Boost: Configured in bridge mode to drive a powerful passive subwoofer in modular PA systems.

Frequently Asked Questions

• Can I connect this amplifier to a standard rack?
  Yes, the VXA-3000 has integrated mounting ears and standard 19-inch dimensions, occupying 2U (two units) in height.
• What does the "Ground Lift" switch mean?
  This switch isolates the signal ground from the chassis ground. If you hear a low hum in your speakers, flipping this switch usually eliminates the noise.
• How do I connect the speakers in Bridge mode?
  You must put the rear switch in "Bridge" mode, connect the signal to channel 1 (or left) and connect the speaker using the positive (+) terminals indicated on the back (usually the red poles of both channels, as indicated by the silkscreen).
• Are the output connectors compatible with Speakon?
  Yes, the NL2 outputs are compatible with standard 2 and 4 pole Speakon connectors.
