Erebus Orifice from Zerosum Inertia

video upload by NOISEBUG

"A. Description:
The Erebus Orifice is a synthesizer module designed for processing audio signals.
It is also capable of generating audio which can be manipulated with Control Voltage.
The Control Voltage is made possible with the help of a VTL5C3 vactrol.
Modulation sources providing 0-10v signals are ideal, 0-5v signals will work too.
The basic design of the Erebus Orifice is a tube preamplifier with a tweaked feedback path.


B. Inputs, Outputs and Controls
There are 3 jacks available:
Enter is where audio signals are to be inserted.
Exit is where audio leaves the module.
CV is where Control Voltage signals are to be inserted.
There are 2 knobs available:
Top knob controls feedback.
Bottom knob controls gain.
The purpose of a knob is to manipulate the behavior of the audio signal being heard.
Twist the knobs and observe the results.
Choose your own adventure.
There are only 2 directions to go: left or right.

C. Power details
The tube used is a 7 pin 6CB6 sharp cutoff pentode.
The use of the tube requires the user to have a power source capable of providing
150 mA of +5 and 30 mA of + and -15 on average load.
The plate voltage is 48 volts and there is no risk of injuring the user.

D. Mounting details
The module is designed to take up 1 space in a synthesizers.com cabinet
sometimes referred to as "MU" for Moog Unit.
The Erebus Orifice is not designed to recreate or emulate such circuits.
It is an addition to the large format modular system, not a clone of any other design.
Rear depth of the module is a shallow 1.9 inches.
Power connection is provided by a 6 pin MTA connector  compatible with Synthesizers.com power distribution systems and QPS1 and QPS3 supplies.
The panel is 3mm thick aluminum with machine engraved print.
Panel will not flex or bend and print will not flake off."
