Control Features and Connections Audio Signal Path Diagram The 2-pole Filter is a full analog signal processor with the following signal path: The input signal is first pre-amplified and then sent to the processing circuitry. This processing consists in a chain of three elements: Rectifier module - Multimode filter - Overdrive module. Finally, the signal is attenuated and buffered to provide the output. w The Activate switch provides a true bypass functionality on the signal path.
Introduction Introduction About this Manual Highlighted Control Features and Parameters This manual was written to help you getting familiar with the 2-pole Filter. It will also aid experienced users with routine tasks. All of the 2-pole Filter´s buttons, controls and parameters are highlighted in bold letters throughout the manual. Example: To avoid confusion, the terminology in this manual is based on the 2-pole Filter parameter names.
Introduction General Safety Guidelines Power Supply m • Unplug the device when you are not using it for longer periods. • Always pull the plug when unplugging the device, never the cable. Please read the following safety tips carefully! They include several precautions you should always observe when dealing with electronic equipment. Read all of the instructions before operating your device Operation Suitable Operating Conditions • Use the device indoors only.
Introduction Maintenance • Do not open the device or remove the cover. Refer all service and repair tasks to qualified personnel. There are no user serviceable parts inside the chassis. • Use only a dry, soft cloth or brush to clean the device. Never use alcohol, cleaning solutions or similar chemicals. They will damage the surface of the chassis. Proper Use This device is designed exclusively to process lowfrequency audio signals for the purpose of generating sound.
Setup and Connection Setup and Connection Connections Package Contents In order to get started with your 2-pole Analog Filter, you will need an AC power outlet. For the connection of the audio output, you will need either a mixing console or an audio interface. The Waldorf 2-pole Filter package comes complete with: • the Waldorf 2-pole Filter module • an external power supply (DC 12V / 500mA) • a printed quick start guide with use cases w + To connect the devices: 1. Turn all units off. 2.
w m If you do not choose to connect a mixing console, you can patch the 2-pole Filter’s output signals directly to an amp or an audio interface. Use an input usually called Line, Aux or Tape input. Before connecting and disconnecting the 2-pole Filter from a power supply source, turn your amp’s volume control all the way down to avoid damage due to on / off switching noise. The 2-pole Analog Filter produces a high level output signal.

Basic Operation Envelope Input Basic Operation This input drive the envelope follower unit. It is suitable for a regular synthesizer control voltage (supported voltage range: 0 V – 5 V), a foot-pedal (best impedance range: 10 k – 47 k) or a line level audio signal (audio interface, drum computer output etc.). The incoming signal is added to the envelope follower input. If you want the envelope following the input signal only, the trigger unit has to be disabled.
2-pole Parameters 2-pole Parameters LED indicator above Gain shows whenever an audio signal is present. The Waldorf 2-pole Filter consists of numerous soundshaping components. Of course, the pre-amplifier can be overloaded to get a saturated input sound. It is up to you to rise the gain, to obtain sounds ranging from smoothly saturated to real dirty / hard clipped. Activate Switch When activated, the signal is routed through the filter and the filter drive.
2-pole Parameters Rectify Cutoff Full-wave rectification is a type of audio signal processing where one half of the signal is inverted. Rectify is the dry / wet control for blending the incoming signal with the rectified signal. For your information: The rectifier stage is directly located before the filter module within 2-pole’s signal path. Cutoff controls the corner frequency of the lowpass and highpass filter types and the center frequency of the band pass.
2-pole Parameters Env Mod [ (= Envelope Modulation Amount). This bipolar control sets the amount and direction of the envelope modulation on the cutoff frequency. For positive settings, the filter cutoff frequency is increased by the envelope, for negative settings, the cutoff frequency is decreased. Use this parameter to change the timbre of the sound over time.
2-pole Parameters trigger sensitivity by using the Threshold control. Envelope Section w • Gate Trigger (middle setting) generates a continous state that lasts as long as Hold Time. You can set the trigger sensitivity by using the Threshold control. Hold Time can lenghten the trigger time, if necessary. • Envelope Follower (downmost setting) means, that the filter envelope is driven by the input signal itself. Threshold and Hold Time have no influence at all.
2-pole Parameters Decay Hold Time Decay is the rate used for the envelope to go down. If Mode Selector is set to Gate Trigger, Hold Time determines how long the envelope is in attack phase. If Mode Selector is set to Pulse Trigger, Hold Time determines the minimum time before any retrigger. Threshold Trigger Button / LED Threshold determines the sensitivity of the envelope trigger. Signals exceeding the level trigger the envelope.
2-pole Parameters LFO Section Speed Speed sets the frequency of the LFO depending on the position of the Range selector. At low settings, it might take some time for the LFO to perform a complete cycle while higher settings are up to the audible range. w Range The 2-pole Filter is equipped with a low frequency oscillator (LFO) that can be used for cutoff modulation purposes. The LFO generates a periodic triangle waveform with adjustable frequency and depth.

Appendix changed in some manner. For instance, an envelope that modulates the cutoff frequency of a filter opens and closes this filter so that some of the signal's frequencies are filtered out. An envelope is started via a trigger, usually a fixed trigger. Normally, the trigger is a MIDI Note. The classic envelope consists of four individually variable phases: Attack, Decay, Sustain and Release. This sequence is called an ADSR envelope.
Appendix pass, all others are dampened. A band stop filter does just the opposite, i.e. it dampens only the frequencies around the cutoff frequency. The most common type is the low pass filter. Low Pass Filter Synthesizers are often equipped with a low pass filter. A low pass filter dampens all frequencies above its cutoff frequency. Frequencies below the cutoff point are not affected. Filter Cutoff Frequency The filter cutoff frequency is a significant factor for filters.
Appendix 2-pole Filter use a full-wave rectification where the negative half of the waveform is sign inverted. Trigger A trigger is a signal that activates events. Trigger signals are very diverse. For instance, a MIDI note or an audio signal can be used as a trigger. The events a trigger can initiate are also very diverse. A common application for a trigger is to start an envelope. Release An envelope parameter.
