TECHNICAL SPECIFICATIONS

LEVELS

•  maximum input levels: not a problem. You can inject signals well above the standard 700/1000mV of 

several hi-end and commercial devices. We tested the VERTICE in a very large scale of input voltages, even 

the absurd 10Vpp (+/-5V) of the Synthesizers.com Q106 VCO (we say “absurd” in the case of direct audio 

use, but obviously it's made with great wisdom if intended like a CV module...). So not be worried about the 

maximum input voltages: it is /-13V, an unreached threshold by every kind of audio equipment of 

all time, if you exclude some truly vintage valve design, and even in this case it is a very uncommon level. 

However giving a 30Vpp (+/-15V) in the audio inputs can be destructive, but maybe not fatal. Our machine 

has balls.

•  maximum output levels (@max A level+max VCA level+max EG level @ VCA+triggered EG):

- Mono/Parallel out: 9-10Vpp

- Stereo/Serial   out: 9-10Vpp

- A and B Rear    out: 14,6Vpp

•  normal output levels (@max A level+max VCA level+EG @ VCF+medium emphasis settings): 1,5-2Vpp

CIRCUITRY

The VERTICE is fully analog. The only time it saw a computer it was for pcb proto and trimming tests. And maybe 

for one or two goodbye takes before it leaves us. 

The VERTICE is fully analog and you notice that even before you switch it on, because of it's weight. However if 

you are curious to see the internal circuitry you will notice that no-one digital chips are used, even the little 7555 

timer are avoided. We just prefer not.

Digital may do spectacular things and we know that. But we also think that everyone may do the job that's right 

for himself. So OK digital, but "

staccato"

 from our pcb's.

Looking into VERTICE

If you unscrew the four handle holdings screws you can easily reach the circuitry. Please take care to 

UNPLUG the power cable from the wall socket before open or touch anything. 

THERE IS THE 220V/110V 

INSIDE THE UNIT EVEN IF IT IS TURNED OFF. It is on two different point and touching them by accident is 

not so difficult (trust me...). Be careful, especially if you’re not an electronic pro (as said, unplug that power 

cable and no problems can occur).

As always taking a look inside your new machine can be a rich source of knowledge about it and about the 

rest of the world. Please note the dimensions of our pcbs, of our power supply and related anti-EMF carter, 

the cure about the internal graphics and cables, the aluminum panels, the not-conductive finish method, 

eventual date and signs inside the unit (!) and so on.

Our aesthetic and technical research are made with extreme care and look inside the machine this is readily 

apparent. And we are honestly proud of the result.

VARIOUS

•  All pure through hole tecnology, slowly hand mounted by the machine creator. For vintage unit all single 

old component is manually checked, every rheophore is cleaned with propyl alcohol and double welded

•  Low production rate (max 20 unit/year), high quality standards for a reliable devastation of your sawthooths

•  Neutrik female ¼” TS mono connectors and TRS N.C. stereo connectors (EG Gate, AM In and Head Out)

•  Heavy phenolic fluted knobs with white top indicator line. Easy to turn, satisfactory touch sensations, 

fashionable vintage looking, "touch-my-tits-please" message to the eyes.

•  Alpha carbon potetiometers (15000 cycles @ full load)

•  Finger-breaking panzerfaust switches, to pretend to be on a T34 tank (100000 make and break cycles @ full load)
