No  Need  for  DI/Direct  Boxes  or  Mic  Preamps,  the A Designs KGB 1tf and  KGB-II  are  instrument pre-amplifiers  that  gives  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.

A Designs KGB 1tf & KGB II General Features: – All Metal Chassis – Discrete “Class A” Operational Amplifiers – Milled Aluminum Knobs – Cinemag Transformer Balanced Outputs – XLR Gold Neutrik Output Connectors – Switchcraft 1/4″ Phone Input Jacks – 1% Metal Resistors – Blue Led Power Indicator – 4 Rubber Feet – External 20-24VAC Power Supply (supplied US only) – Input Gain Select Switches – Phase Reverse Switches – Ground Lift Switch A Designs KGB 1tf A Designs KGB 1tf  is the single channel version with a three- band fixed frequency equalizer and the addition of an extra duplicate parallel transformer output (balanced) via a TRS ¼ inch phone jack. The tone controls are a modified Baxandall circuit with high/low shelving corner frequencies at 5 kHz and 180 Hz. The Midrange frequency is handled by a peaking EQ section with a broad Q centered at 1.8 kHz. Each section is capable of up to 12 dB of cut/boost. Further Information 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,   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   “Class   A”   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   pickups   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.
