Balanced Audio Technology VK-90 Preamplifier

The Unistage design uses a single gain stage to process the audio signal. By eliminating extra stages and capacitors, it keeps the signal path as short and pure as possible, which helps prevent the coloration or distortion often introduced by more complex circuits.

Yes, the VK-90 is built on a fully balanced, zero-feedback architecture. To get the most out of its superior channel separation and noise rejection, it is best paired with balanced XLR components throughout your signal chain.

The transformer-coupled outputs use mu-metal shielding and high-quality Cardas copper wire to isolate the signal from noise. This results in a cleaner, more transparent output that maintains the integrity of your music before it reaches your power amplifier.

The dual-mono power supply ensures that the left and right channels are powered independently. This design prevents crosstalk between channels, providing a wider soundstage and more precise imaging.

Yes, the VK-90 features five XLR inputs, allowing you to connect up to five balanced audio sources simultaneously. It also includes two main XLR outputs and one dedicated tape output for added system flexibility.

The SuperPak utilizes a silver/oil hybrid construction that provides high-speed energy storage. This allows the preamplifier to respond quickly to dynamic musical transients, ensuring the sound remains punchy and detailed.
