Each waveform´s level can be adjusted with a dedicated volume slide potentiometer and is available at a separate output jack. The sum of the OSC1 and OSC2 waveforms can be blended either manually with the large potentiometer in the middle of the module or via CV and is available at the main OUT socket. Each sum is also supplied at the OSC1 and OSC2 output jacks separately (after BLEND). OSC1 (Principal Oscillator) NOISE - White Noise with a fixed high pass filter at 320Hz. SUB - Two Sub-octave waves based on the SAWTOOTH waveform. They can be activated individually with the SUB -1 and SUB-2 switches. PULSE - PULSE waveform with adjustable PULSE-WIDTH via PW knob or CV with a dedicated attenuator PWM CV. TRI/SAW - Either a TRIANGLE or SAWTOOTH waveform according to the TRI/SAW switch. TONE - Accentuates either low or high frequencies of all OSC1 waveforms. FM - FM input for either EXPONENTIAL or LINEAR FM, adjustable via FM switch (mid position is off). V/OCT - 1V per octave input and a precision duplicate output of the incoming CV signal for further external processing. FRONT PANEL CALIBRATION & GAIN - A trimmer potentiometer for V/OCT tuning and OSC GAIN is located on the front side of the module. OSC2 (Principal Oscillator) TRI/SAW - Either a TRIANGLE or SAWTOOTH waveform according to the TRI/SAW switch. PULSE - PULSE waveform with adjustable PULSE-WIDTH via PW knob or CV with a dedicated attenuator PWM CV. OSC1´s PWM CV input is normalized to the OSC2 pulse-width modulation input. TIMBRE - Buchla inspired timbre generator. The timbre setting can be changed with the TIMBRE knob or via the CV input with an attenuator. SINE - Pure and analog SINE wave. FM - Either EXPONENTIAL or LINEAR FM, adjustable via FM switch (mid position is off). Can be generated internally or via external CV. FM VCA - The FM input´s amplification can be controlled via an internal VCA. As soon as a jack is plugged into the FM VCA input jack FM modulation will only be applied in accordance to an incoming CV signal (such as an LFO or Envelope Generator). OSC SYNC - OSC2 can be loosely or tightly synced to OSC1. OVERLOAD - Feedback Distortion with Clipping LED for all OSC2 waveforms. V/OCT - Separate 1V per octave input. OSC1´s 1V/OCT signal is multiplied via a precision buffer and normalized to OSC2´s 1V/OCT input, if no jack is present at the OSC2 V/OCT input. This routing can also be deactivated with the V/OCT INV switch. Additionally the normalized V/OCT signal can be inverted and routed to OSC2, if the V/OCT INV switch is in the down position. FM OSC (Modulation Oscillator) FM OSC only modulates OSC2´s frequency. The RATE can be set with the FM RATE knob. The oscillator´s waveform can be changed from TRIANGLE to OFF to SQUARE WAVE with the FM switch. The amount of modulation applied can be adjusted with the FM CV attenuator, if no jack is plugged into the FM input jack. An LED indicates if FM modulation is active taking any FM VCA modulation into account. With the help of the the FM switch the modulation type can be set to either exponential or linear. MOD OSC (Modulation Oscillator) The MOD OSC is a low frequency oscillator that internally controls BLEND CV, OSC2 TIMBRE CV and OSC1 PWM CV (which is normalized to OSC2 PWM CV). Its RATE can be adjusted with the MOD knob and the final depth is set by the destination CV attenuators BLEND CV, PWM CV and TIMBRE CV. The oscillator´s waveform can be changed from TRIANGLE to OFF to SQUARE WAVE with the MOD switch. MIX & BLEND In order to mix both principal oscillators and their waveforms OBERHAUSEN features two 4-channel mixers and a additional blend mixer. With the help eight dedicated slide potentiometers each waveform´s level can be set. Additionally you can blend between OSC1 and OSC2 either manually, via CV at the BLEND input jack or internally with the MOD OSC and BLEND attenuator.

Mixer & VCA duck / duck ing module / 4 HP ⇣ If you ever have an issue with an overcrowded and muddy mix or you just want to achieve that „sidechaining-sound“, DUCK will bail you out without any signal compression. 1/3 key features Duck ing/Sidechaining Module Amount Control Duck ing Envelope Controls CV Input Wrong polarity protection specs & downloads width: 4 HP depth: 40 mm power: 35 mA @ +12V / 25 mA @ -12V documentation videos description / manual DUCK is a duck ing or sidechaining module that reduces the level of an audio signal when a CV GATE signal is applied. Trigger CV will work, but then you won´t be able to create slow duck ings. The module has four potentiometers that control the way the signals is „ duck ed“: AMOUNT sets the overall effect of level reduction. Fully counter-clockwise the level will be released to a maximum amount possible. Fully clockwise there is no level reduction at all. This lets you smoothly fade out the duck ing effect which is very useful in live situations. It also give you control over how much of the inserted signal should be reduced in level. HOLD determines the length of level reduction when the gate signal at the GATE input jack is high. If HOLD is turned to the left you will have a rather „plucky“ type of level reduction. RISE sets the amount of fade-in that‘s applied to level reduction. The more you turn RISE to the right, the slower duck ing is introduced, when gate is high. You can create some really slow fade outs with large rise values. The potentiometer is pretty sensitive here, leave it fully counter-clockwise to have short duck ings. FALL sets the mount of time the signal needs to fully recover from level reduction. In conjunction with RISE you may create some very slow fade-in and fade-outs with these controls. Obviously you can also set both to a very quick and responsive level reduction, especially if you are using duck ing together with a kick drum. Two LEDs indicate the signal level (left LED) and the level of signal reduction (right LED). Additionally you may control level reduction via CV. Any positive signal patched into the CV input will reduce the level of a signal applied to the IN jack. If you use the CV jack, HOLD, RISE and FALL will have no further effect. prev Up next

Effects gritzner / pt2399 delay with two switchable inputs and internal lfo / 8 HP ⇣ GRITZNER Delay is a special kind of module that is able to make all sorts of weird delay sounds, from chorus like effects to total destruction of the original signal. There are no boundaries for your crazyness here. Though the two switchable inputs and the LFO reset always make its output fit into a rythmical pattern of your patch. 1/3 key features PT2399 Delay Two Switchable Inputs, one High-Pass-Filtered Internal LFO for Input Switching Internal LFO for Delay Time Changes LFO with Attenuator and Reset Delay Time CV Input Skiff friendly Wrong polarity protection specs & downloads width: 8 HP depth: 28 mm power: 50 mA @ +12V / 30 mA @ -12V documentation videos description / manual GRITZNER is a short delay with two individual inputs that may be activated alternativley either by hand or with a gate signal. IN A is a standard audio input whereas IN B is a high pass filtered input. Frequencies below 320hz will be filtered out which is quite handy for some delay settings. If the MAN/LFO switch is on the left you can switch between both inputs manually using the A/B MAN switch. If the MAN/LFO switch is in the right position an internal square wave LFO automatically switches between both inputs according to the LFO range set with the help of the LFO potentiometer. Alternatively you may patch an external gate signal (from a sequencer for example) into GATE A/B in order to switch between inputs. The Delay itself is a classic PT2399 delay with its very special touch and a delay time ranging from 30-190mS. It has manual controls for the Delay Rate (going beyond the ICs operation range), Feedback and Wet. The delay rate can be voltage controlled with an external signal or with the help of an internal LFO. You can choose between a triangle and a square wave LFO and you may attenuate its signal with the LFO ATT attenuator. On top the LFO is resettable via the LFO RST input in order to get delay changes in a rythmical manner. The LFO rate can be adjusted with the LFO potentiometer. prev Up next
