Owen Posted March 2, 2016 Share Posted March 2, 2016 (edited) This is an exceptionally nice piece of kit but I have too many amps. Much as I would love to, I cannot keep everything. The EQ is really responsive in a useful, musical way. The dark/normal/bright switch is a lovely thing. I fancy keeping it, but I cannot keep everything (yes I am repeating that so that I remember). I will get some pics up later. Specs: [b]Tone section:[/b][list] [*][b]Treble Control: [/b]The treble control gives 6 dB of boost or cut at 4 kHz (6dB per octave, shelving type). [*][b]Middle Control:[/b] The middle give 6dB of boost or cut at 500Hz (wide Q, peaking type).Bass Control: The bass control gives 9dB of boost or cut at a selectable frequency of 60Hz or 120Hz (6dB per octave, shelving type). [*][b]Presence Control:[/b] The presence control gives up to 12dB of boost at a selectable frequency of 2kHz or 4kHz (active type, 6dB per octave). [*][b]Mode switch:[/b] Dark, is a high frequency cut fatting up your fundmental. Normal, flat opertion showing off more overtones. Bright, brings out the overtones on the dullest basses or speakers. [*][b]Internal Volume Trimmer: [/b]This control is designed to match the output volume of the VTBP-M-800D with the sensitivity of any Bass. [*][b]Effects Loop: [/b]in/out line level [*][b]Power Amp Outputs:[/b] Operating at 4 (800w), 8 (500w) or 16 ohm (250w). 1/4” & Speakon [/list] [b]Preamp Specifications[/b] [list] [*][b]Inputs:[/b] one instrument level 1/4” jack.
