KGB-II and KGB-ITF

 

The KGB-II and KGB-ITF are single-ended, high input impedance, discrete audio pre-amps designed for high impedance, unbalanced outputs such as: guitar, bass guitar, and electronic keyboards. Just as a low impedance, balanced pre-amp is needed, (designed for use with microphones), a pre-amplifier designed for use with unbalanced high impedance instruments is also required. The KGB Series contains high voltage, discrete op-amps with balanced output transformers by Cinemag, Inc.

 

The KGB-II is a two-channel, solid state unit that allows use of both channels for stereo recordings or live performances. This works well with stereo output instruments such as: keyboards or stereo guitar pickups. For bass players, there is freedom to use two basses in a live performance, simply by picking up the other bass and playing without any delay between songs.

 

The KGB-ITF (Tone Filters) is a mono unit . It has the same features of the KGB-II, but includes three tone controls, High, Mid, and Bass.

 

GENERAL FEATURES:
– All Metal Chassis

– Switchcraft 1/4″ Input Jacks
– Bipolar Electrolytic Capacitors
– 1% Metal Resistors
– Blue Led Power Indicator
– 4 Rubber Feet
– Heat Vents
– Two Discrete Inputs with Thru
– Gain Select Switches for each channel – High/Low
– Phase Reverse Switch for each channel
– Gain Lift Switch
– External Power Transformer for a very low Noise Floor
– Single Discrete Input with Thru
– Gain Select Switch – High/Low
– Phase Reverse Switch
– Ground Lift Switch
– External Power Transformer for a very low Noise Floor
– Three Band fixed frequency Tone Filter with 12db cut/boost – High/Mid/Low

APPLICATIONS:
– Output to Line-In to FOH or Stage Monitors.
– Output to Line-In on a Recording Console.
– Output to Input of Digital Audio Converters.
– Output to Power Amplifiers.
– Both devices provide a Balanced, Line-Level +4db Output, which allows for bypass of the typical DI, Microphone Preamplifier and other input stages.
