REX 3 Preamplifier

Vacuum-tube power module now incorporates third-generation SuperPak Assembly

To support the control module’s signal-handling needs, the separate REX 3 power module contains 10 vacuum tubes supported by two, large toroidal transformers in true dual-mono configuration. Vacuum-tube rectifiers and user-configurable current sources—as well as vacuum-tube AC shunt regulators—provide further levels of refinement. The final filtering stage employs BAT’s newest SuperPak assembly, featuring additional bypass oil capacitors to deliver an even lower noise floor.

Trademarked Unistage design anchors control module

The signal in the REX 3 is transmitted through only one gain stage. Its Unistage circuit provides the ultimate simplicity of amplifying the incoming signal only once, while using zero global feedback. Eight 6H30 SuperTubes in the control module achieve extraordinarily high-current, low-impedance drive capability. Indeed, REX 3 would need nearly three dozen 6922 tubes to offer the same current delivery! But REX 3 doesn’t stop there. Imagine the robust nature of a vacuum-tube power supply designed to support such instantaneous current delivery, and you have a better idea of REX 3’s incomparable abilities and build.

More than just a preamplifier with an external power supply

Contrary to its external appearance, REX 3 is not simply a preamplifier with an external power-supply box. This conventional type of partition suffers from several well-known drawbacks, foremost being the high-impedance nature of the remote power supply. In REX 3, the control box offers the benefit of a low-impedance local power supply. BAT designed each box to contain the complete power supply for one polarity. What’s more, the size of each individual supply compares to that found in many power amplifiers!

Extreme performance, engaging musical reproduction

Easy to operate out of the box, REX 3 is just as simple to customize. Name your sources. Fix your volume for the MOVI input to take effortless control of your home-theater system from your pre/pro remote. Select a fixed balance adjustment for the phono input to accommodate an older phono cartridge. The possibilities are seemingly endless. Most importantly, REX 3 provides utterly beguiling levels of transparency, dynamic scale, and textural insight. The 18-tube statement lets you hear and feel the power, finesse, and beauty of music in ways you’ve never imagined.
