We offer a special power supply for the Trinity Pro Preamp with a slightly lower voltage output to avoid noise issues on the mic channel.

The Power Supply for Quantum Preamps works with Quantum Blender, Pure XLR Mach 2, Meridian Preamp (not Pro).

 

Preamp Power Supply

Designed to run our 9-volt battery-powered preamps, this power supply is especially efficient with most of our 2-channel preamps due to their relatively high power consumption.

Works with these preamps: Pure Preamp, Pure XLR Preamp, Dual Channel Pro & ST Preamps, PowerMix Pure XT, Bass Master RB, Bass Master Pro, Meridian Pro Preamp.

Not to be used with: Trinity Pro Preamp, Quantum Blender, Pure XLR Mach 2 Preamp. We offer different power supplies for these preamps (see other available options, left).

With our noiseless Preamp Power Supply, you can save batteries plus get better performance out of your preamp's circuit. This means better headroom, more clarity, lower distortion, and lower noise. Regular power supply adapters have a 60 Hz hum, but this supply has a special noise suppression circuit.

Use it whenever you do not need the extended freedom of movement with battery operation, save money on batteries, and get a cleaner sound with the noiseless Power Supply. All K&K preamp circuits can easily be driven by 12 volts without any risk of damage.

Connecting the Power Supply

Simply hook it up to the battery clip, instead of the battery. The thin and strong 3/32" cable exits on the in/output jack side of the preamp between lid and rear panel. The new K&K dual-channel models even have a little notch for the cable above the center jack (see picture #2). We use this thin cable for the first 5 feet in order to provide a comfortable weight and feel and of course to allow for use with any existing K&K preamp even without the notch on the rear panel.
