K&K Pure XLR Preamp Mach 2

What makes the Pure XLR Mach 2 Preamp sound so good? The circuit runs on a “voltage doubler” that provides 18 volts to the internal components even though it uses standard 9 volt input voltage. The result is high-powered clarity that simply cannot be achieved with a regular 9-volt circuit! Electronic circuits work more efficient on higher power and electronic components designed for low power consumption will never sound as good as the more power-hungry components that are optimized for tone quality.

There is a direct relation between power consumption and sound quality, meaning that preamps with 200+ hours battery life will compromise on sound quality. Phantom powered preamps, depending on their complexity, also need to compromise on power consumption issues as phantom power fluctuates and diminishes with the number of consumers connected. Generally, low power consumption equals less high-end response, less headroom (circuit peaks or overloads sooner), and less overall clarity. At K&K, we've always favored sound quality over power consumption in our external preamp line, but with the Pure XLR Mach 2 Preamp we went even further and run it on 18 volts.

This feature alone would make the new Pure XLR Mach 2 Preamp worthwhile, but we added a few more things that players have asked for:

• +/- 15dB Parametric band that covers 150Hz to 700Hz with adjustable notch width
• Full bypass of parametric stage if not needed
• Tuner output
• Mute switch input
• In addition to these features:
• Proprietary K&K high-power three band EQ (bass – mid – treble)
• Adjustable input gain
• Phase switch
• Master volume
• Simultaneously usable 1/4” line out and balanced XLR – DI output
