the vsp-2 is vertigo sounds 3rd big impact design and is settinga new benchmark in microphone amplification.

the heart of this unit is vertigo sound discrete twin opamp circuit called the opa (operational amplifier) 1976.

these "in house" engineered & built discrete amplifier stage iscombined with jensens world famous jt-16 mic transformers andprovide a smooth warm and defined sound from the lowest bass to thevery top end of the sonic spectrum.the jt-16 transformer can handlevery high input levels and provides a very linear phase behaviourbecause of low capacitance problems due to it`s low ratio of 1:2.further the low ratio of the transformer forces the discrete op ampto provide most of the amplification in the vsp-2. this " fullthrottle","pedal to the floor" circuitry enables a unique, rich,full and characterful sound.

controls:

gain control: 10-position grayhill rotaryswitch with 6db stepincrements. the full range of the unit is 12-72db

fine gain control: 41 click alps 0-6db fine gain trim

120hz/off/80hz: switch that engages lowcut input filter 12db/octat 80hz or 120 hz.

signal & clip led: this led either indicates green for areasonable signal level presence at the output or red for close tooverload. there is no inbetween orange state to indicate clippingclearly.

led green: - 6dbu to 19dbu at the output of the vsp-2>>>> reasonable output level

led red: +19dbu at the output of the vsp-2 >>>>close to clipping level

note: the maximum output of the vsp-2 is +24dbu, the redclipping led indicates the maximum capable input level of mostcommon converters and analog gear.

instrument in: this is an unbalanced input for guitar, bass,samples, etc. this unbalanced input goes directly to the twin opainput without using any circuitry inbetween. (real di input) simplythrow the toggle switch and you're off. the output is muted whenswitching to avoid loud clicks in your monitors.

48v : 48v switches ramped phantom power.

-20db: pads the input signal 20db down. the pad does not affectthe input impedance of the vsp-2! the pad circuitry is switched outof the input stage completley when disabled.

please use the pad for the gain settings 12db-18db-24db and 30dbonly!!! the pad does not effect the sound of your signal butsettings like 54db with pad engaged e.g. will worsen your signal tonoise ratio.

phase: reverses the polarity of the pre amp's output.

 

the heart of the vsp-2 – the discrete op amp 1976

99% of all newer designs use an i-ntegrated c-ircuit for thisjob which makes production easy and cost extensive. here's the bigdifference!

the vertigo sound 1976 is a fully discrete operationalamplifier.

this very well thought out classic circuitry together with thejensen jt16 transormer and panasonic coupling caps plus thespecific choice of components of the op amp gives you a fresh,punchy precise colourful sound without sounding dull or nasty atanytime.
