Vonyx VDA1000 - Class D Stereo PA Power Amplifier 2x 500W (1U Rack)
The Vonyx VDA1000 represents an evolutionary leap in professional audio engineering, offering a high-performance amplification solution in an incredibly compact format. Part of the VDA series, this stereo amplifier has been designed for sound engineers, installers, and musicians who require reliable power delivery without the bulk and weight of traditional power amplifiers. Thanks to its advanced Class D technology, the VDA1000 delivers 500W per channel into 4 ohms (350W into 8 ohms), while maintaining superior energy efficiency and minimal heat dissipation.
One of the most outstanding features of this model is its physical design. At just one rack unit (1U) high, this amplifier maximizes space in transport racks or fixed installations, which is vital in crowded DJ booths or studio control rooms. Despite its slim profile, the construction is robust and durable, ready to withstand the demands of constant mobile use. Its quiet operation makes it a prime choice not only for noisy events but also for environments where background fan noise might be intrusive.
In terms of connectivity, the Vonyx VDA1000 offers professional versatility. The rear panel is equipped with combo jacks that accept both 3-pin XLR connectors and 6.3mm jacks , facilitating connection to a wide range of mixing consoles, signal processors, and preamps. For speaker output, it uses standard NL-4 connectors, ensuring a secure connection and preventing accidental disconnections during performance. The front panel includes LED indicators for signal and overload (clipping), allowing the user to monitor the amplifier's status in real time and protect the equipment from signal spikes.

Benefits for the user
The Vonyx VDA1000 is designed for professionals who value portability without sacrificing performance. Its lightweight design, at approximately 3.1 kg, greatly simplifies transport and setup, reducing logistical strain on tours or mobile events. By taking up less rack space, it allows technicians to fit more processors or equipment into a single carrying case. Furthermore, its high energy efficiency results in less heat generation, contributing to a longer lifespan for internal components and greater thermal stability within the rack.
Use cases
-
Mobile DJs and Mobile Discos: Thanks to its light weight and power, it is perfect for powering passive speaker systems at weddings, parties and private events.
-
Fixed Installations in Hospitality: Ideal for bars, restaurants and pubs that need a powerful but discreet sound system that can be easily hidden in a small rack.
-
Stage Monitoring: Its compact format allows it to be used to power stage monitor wedges without taking up vital space on the stage or in the main amplification rack.
-
Recording Studios and Rehearsal Rooms: Its quiet operation and flat frequency response make it suitable for amplifying passive reference monitors.
Frequently Asked Questions
-
Can it be mounted in a standard rack?
Yes, the VDA1000 is specifically designed to be mounted in standard 19-inch racks and occupies 1U in height.
-
What type of speaker cable do I need?
This amplifier uses NL-4 outputs, so you will need speaker cables with Speakon (NL-4) compatible 2 or 4 pole connectors.
-
Is it compatible with 8 Ohm speakers?
Yes, it works perfectly with 8 Ohm speakers, delivering 350W per channel at this impedance.
-
Does it have noisy fans?
