FLAMA +MIRROR Unipolarinverter
Short description
The module is an inverter for exclusively positive voltages. It inverts an applied positive volta-ge so that the maximum value becomes zero and zero becomes the maximum value. The input voltage is therefore not inverted into the negative voltage range (mirror axis 0v), but reflects a positive voltage around an adjustable axis within a fixed positive voltage range from 0v. There are 10 ranges, adjustable in 1V steps. The mirror axis is always on half of the set range. Negative voltages cannot be inverted with this module. Applied negative voltages are limited to approximately zero volts. The module has two identical function groups. Applications are, for example, the inversion within positive voltage ranges, GATE inversions (0/+5v to +5v/0v), or opposing melody lines (in connection with a connected quantizer).
Hardware / Connection
Connection to the euro rack modular system (Doepfer bus)
The module is delivered with a connected ribbon cable for the Doepfer bus. The red lead marks -12 volt. Connecting the module please note the right polarity! If the module is poled accidentally wrong safety diodes avoid the immediate destruc-tion of the module but further damages can-not be excepted.
So please pay attention: Check the con-nection various times before
switching on!

HANDLING
FUNKTION
The “+MIRROR” module is a unipolar inverter. Only positive voltages are
inverted around a mir-ror axis. The module inverts an applied positive voltage
in such a way that the maximum value becomes zero and zero becomes the maximum
value. The input voltage is therefore not inver-ted into the negative voltage
range (mirror axis 0v), but reflects a positive voltage around an adjustable
axis within a fixed positive voltage range from 0v. There are 10 ranges,
adjustable with a rotary switch in 1V increments. The mirror axis is always on
half of the set range. Negative voltages cannot be inverted with this module.
Applied negati-ve voltages are limited to approximately zero volts.
EXAMPLE:
If the +5V range is set, the input voltage (0..+5v) is mirrored around the
+2.5v axis. For example, with this setting, the inverted output voltages would
be:
- with 0v at the input, the inverted (mirrored) output is +5v,
- with 1v at the input, the inverted (mirrored) output is +4v,
- at 2.5v at the input, the inverted (mirrored) output is +2.5v,
- with 3v at the input, the inverted (mirrored) output is +2v,
- with 5v at the input, the inverted (mirrored) output is 0v.
If no cable is plugged into the input socket, the output voltages can be
adjusted manually with the “Manual” potentiometer. There are then two opposing
(mirrored) output voltages (example with switch position +5v):
The module has two identical function groups, each with a CV input and two CV outputs (one non-inverted output, one inverted output).
APPLICATIONS
- the inversion within positive voltage ranges
- GATE inversions (0/+5v to +5v/0v)
- opposite melody lines (in connection with a connected quantizer).
ADVICE:
Due to the component tolerances, the output voltages have a tolerance of up to
approx. 250mV. The 10V range does not reach the maximum value, but only
reaches about 9.5V.
