Doepfer style power cable included.
Screws not included due to the wide variety of case
and screw types used.

Mounting/Connection tips;
The supplied power cable is keyed.

That means it can only be fitted one way!
(Unless you use excessive force).

Pin one is at the top on our modules

(Doepfer fit their sockets upside-down).

AS Modules use a 14 pin 'boxed'

header on the

.

PCB

The two ends of the power cable are

different. Plug the 14pin socket end into
the Module power header.

Disconnect your case/

from the

PSU

mains, then plug the larger 16pin socket
into your case's power supply.

The pin out on both plugs is the same.

Note: Physically disconnect your power

supply/case from the mains electricity.

Ensure you connect up the module

correctly!

Ensure it is screwed into the case.
Ensure no metal parts can short out the

solder joints on the rear.

Ensure your case is 100% functional

before fitting the module.

Most issues trace back to plugging in

the power cable in incorrectly.

To change the

input level of the

audio signal,

turn this.

Peak (

Resonance) -

AKA

increase this to make the
sound more squiggy. As
it approaches maximum
you will get continuous
feedback & the sound
will be all like eeeeeeee.

Use this to alter

the level of the

CV

signal coming in

socket

The

-

control is used to

CUT OFF

change the tone of the signal.

When

is on

GAIN

(up) then the input

signal is boosted

and the filter input

can more easily

be over-driven.

Use this for a

dirtier sound.

When gain is on

the output level

will be higher.

When Q is on (up) then
the amount of feedback
possible using the

PEAK

control is increased. The
resonance will be more
pronounced - and -
louder! More

.

EEEEEE

If you cross-mod the cut-
off using audio from a
VCO, you will get a more
pronounced affect with
this turned on, and with
PEAK set to maximum.

These are the audio outputs from the
filter.
LP = Low Pass
BP = Band Pass
HP = High Pass
NOTCH = Well, notch.
All four can be used at once.
Or use two for S-T-E-R-E-O filtering.

The Telemark multimode filter is based on the filter of the legendary Telemark semi-modular synthesizer. It's routes lie in
the original 1970s Oberheim

, though it has developed a character of its own.

SEM

The filter is a 12db/Octave multimode type. Multimode means there are more than one type of filter output. There are in
fact four: low pass, band pass, high pass and notch filter. Additionally, notch filter can be varied for an even wider range of
sounds.
Use of Gain and Q allow for even wider possibilities.
No special knowledge is required to use this filter. Just plug your audio in the left, and your audio out on the right.
Optionally (and recommended!) patch a control voltage in to give the sound movement.
