Dual channel device with two independent instrument pre-amplifiers in one box
This gives it great flexibility in many applications like; stereo output keyboards, two different instruments at one time and stereo guitar effects pedals to name a few and by cascading one channel into the other gives an even wider range of options.
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, both the KGB-Itf and the KGB-II are of a "no frills, no compromise" audio philosophy for pure sonic capture and reproduction. Designed by Carl Johnson.
