Limited warranty
Ritual Electronics warrants this product to be free of defects in materials
or construction for a period of one year from the date of purchase.
Malfunction resulting from wrong power supply voltages, backwards
or reversed eurorack bus board cable connection, abuse of the product
or any other causes determined by Ritual Electronics to be the fault of the
user are not covered by this warranty, and normal service rates will apply.
During the warranty period, any defective products will be repaired
or replaced, at the option of Ritual Electronics, on a return-to-Ritual
Electronics basis with the customer paying the transit cost to Ritual
Electronics. The return of your module is on us.
Ritual Electronics implies and accepts no responsibility for harm to person
or apparatus caused through operation of this product.

4Installation
Always turn your eurorack case o before plugging
or unplugging a module.
Do not touch any electrical terminals when attaching any
Eurorack bus board cable.
Ritual Electronics Crime does not require power.
You will need 4HP of free space in your Eurorack case to install
Crime.
I. Remove any diodes present in Miasma’s female
header on the back of the module (fig. I)
II. Connect the male end of the included cable to the
Miasma’s female header, blue stripe must face down
(red stripe if you have a pre-October 2019 module)
III. Connect the other end of the cable to Crime’s
male header, same colour facing down (fig. II)

Overview
Crime lets you chose from 6 dierent diodes for your
Miasma.
There are 2x6 diodes you can chose from using two rotary
switches, one for the positive part of the sound, the other
for the negative part. This way you can easily achieve
symmetrical and asymmetrical distortions.
Crime also has a female header on position VI for you to put
your diodes of choice. You can also have this position witout
diodes for extra harshness, but beware of the output volume!
Crime connects to Miasma with an included cable. It replaces
the diodes in Miasma’s female diode header. This way you
won’t have to take Miasma out of your case to change
diodes and explore new distortion flavours.
Note each diode has a dierent voltage drop, resulting in
dierent loudness. You can still compensate for volume
changes using Miasma’s level trimmer.
Crime can not be used without Ritual Electronics
Miasma.

7Diodes
Miasma uses two diodes to rectify the signal. These diodes
define the colour of the sound.
The diodes create a different shape of distortion. There is one
diode per waveform polarity, to achieve asymetrical distortion.
The diodes influence both the distortion sound and the feedback
texture and pitch.
Different diodes have different current and voltage consumption,
this yield to volume increase or decrease from a configuration to
an other.
Crime has 5 different type of diodes.
Position VI is yours. You can put your own diodes in Crime’s
female header or leave it empty.
The diodes are arranged in “loudness” order. As you go
from position I to V, the diode voltage drop decreases,
resulting in the sound being louder and louder.
I is 1N60, a germanium diode
II is 1N4148, a very classic silicon diode
III is 1N4004, a schottky diode
IV is 1SS133, a silicon diode used in the Metal Zone
V is a Blue LED

8Remarks
Crime has been conceived as a cheap and cheerful
expander for Miasma. It is mainly designed to help you
change diodes without unscrewing your module.
Note that when you switch from a diode to another there
is a brief moment where no diodes are connected resulting
often in a short noise.
Thus the module is more of a “set and forget” type than a
performance tool (even though a good rythmic switching
can be of great effect)
If you decide to mount diode on Crime’s header (position
VI), you can still achieve the “no diode” effect by setting the
switch in-between two positions.
