No Need for DI/Direct Boxes or Mic Preamps , the A-Designs' KGB-II is an instrument pre-amplifiers that give a +4dB transformer balanced line-level output. Plug in your guitar, bass or keyboard into the KGBs (Keyboard/Guitar/Bass) and they will directly drive line level inputs of DAW interfaces, effects processors, power amps and line inputs of recording or FOH consoles without the need for a microphone preamp.

To accommodate any instrument, the front panel features High/Low Gain toggle switches and Switchcraft 1/4-inch Input and Thru Jacks. On the rear panels are balanced XLR output connectors and toggle switches for phase flip (each channel), ground lift of XLR Pin 1 and power on/off. The KGBs are each powered by an external wall transformer of 20-24VAC (supplied US only). A modified voltage doubler circuit is used for generating the regulated +/-24 volt rails that powers the custom designed discrete operational amplifier modules. Both models chassis are built of solid steel for durability. Made in the USA.

The use of CineMag output transformers allows for the use of long transmission line feeds through balanced output cables as for live sound applications. In addition, both KGBs are optimized for guitar and bass guitar pickup impedances, as well as the unbalanced outputs from electronic keyboards such as vintage synthesizers.

Operation is simple and immediate for either unit. The High/Low Gain toggle switch sets the operating range depending on what source you plug in, and a single aluminum knob sets the final output level.

In the studio or on the stage, the KGB-II are of a “no frills, no compromise” audio philosophy for pure sonic capture and reproduction. Designed by Carl Johnson.
