Power Supplies for K&K Preamps

Power Supply for Battery-Powered Preamps

With our noiseless Power Supplies, you can save batteries PLUS get better performance out of your preamp's circuit. This model supplies 10.5 volts (Trinity Pro model outputs 8.6 volts). 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.

It works with US and European voltage (with a simple travel adapter). Use it whenever you do not need the extended freedom of movement with battery operation, save money on batteries, support the environment, and get a cleaner sound with the noiseless Power Supply. And don't worry, all K&K preamp circuits can easily be driven by 10.5 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 extra-rigit 3/32" cable exits on the in/outputjack 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.
