Each has its own Input (IN 1 and IN 2) and Low Pass, Band Pass and High pass outputs. Out 1 is selectable with the four way rotary switch (LP, BP, HP or VARY), additionally the mode of VARY can be swept from LP (Vary control at LP) to Notch (Vary control centered) to HP (Vary knob at HP). As well as being routed to the OUT 1 or (OUT 2) jacks, this output is also sent to the central mixer bus for combining VCF 1 and VCF 2.\u003c\/p\u003e \u003cp\u003eManual Control of Frequency is with Freq 1 (or Freq 2) controls, and there is also a Frequency CV input (FCV 1 and FCV2) allowing the level of Frequency modulation to be voltage controlled. The FCV1 and FCV2 level controls are attenuverters rather than regular level controls, this means that in the center (approx 12 o'clock) position, none of the modulation voltage patched to the FCV1 (or FCV2) input will affect the cut off frequency of the filter, however as the FCV 1 (or FCV2) control is turned clockwise from center then the voltage or waveform applied to the FCV input will increasingly affect filter frequency. If the control is turned anti-clockwise from center then an INVERTED voltage or waveform is applied to the filter cut off frequency, as an example, if +5 V DC voltage is applied to the FCV input, if the FCV control is rotated ant-clockwise than this would apply an increasing negative voltage to the filter cutoff, rather than a positive voltage if FCV control is rotated clockwise of center. This is much more useful than a regular level control, as it combines both level control and inverter in one convenient control.\u003c\/p\u003e \u003cp\u003eThere is also a 1 V\/Octave frequency control input too, this allows the filter to open at 1 V\/Octave for keyboard tracking, or correctly pitched sounds if the filter is in self resonating mode. It can also be used as a second frequency CV control, and this can be very useful when combined with an CV external mixer, such as the AJH Synth CV MIX, Offset\/VCA module - which would allow multiple modulation sources to be mixed. And of course the 1 V\/Oct control works at the same time as the FCV input too, so for example the output of an envelope generator could be patched to the FCV input and the output of a MIDI\/CV converter or sequencer to 1V\/Octave input so that both envelope and pitch tracking are possible simultaneously.\u003c\/p\u003e \u003ch3\u003eThree different Dual Modes\u003c\/h3\u003e \u003cp\u003eThe two independent filters can be combined in three different ways:\u003c\/p\u003e \u003cp\u003eSerial (Cascade) Mode: The mode toggle switch should be set to CASCADE position to select this mode.This connects the OUT 1 output from filter one to the IN 2 input of filter 2, and both filter one and two outputs are routed to the inbuilt cross-fader, the output of which is routed to the D-OUT output.So the signal is first treated by filter one, then this filtered signal is fed for further filtering by filter two.The four way rotary switches select the filter type for each filter signal sent to the Cross Fader, and the AUDIO MIX control allows crossfading between the filter one and filter two outputs, so in this case there is cross-fading between one and two filters. So if, for example, both filter one and filter two are set to Low Pass (LP) mode, then the AUDI MIX control will fade between 12 dB and 24d B Low Pass filter slopes.\u003c\/p\u003e \u003cp\u003eAs another example, selecting LP filter for filter one and HP filtering for filter two will combine to give a Band Pass response, but the frequency and resonance for each component can be individually controlled. This is quite different from using the BP setting on one of the individual filters, as it doubles the BP filter slope from 6 dB to 12 dB, but allows much more control over the BP characteristics too, and in this case the AUDIO MIX control would fade between LP (filter one) and BP (filter one and two in series). And of course any filter type from filter one and filter two can be combined.\u003c\/p\u003e \u003cp\u003eParallel (Dual) Mode: The mode toggle switch should be set to CASCADE position, and the INVERT switch set to VCF2 position to select this mode.This internally connects the output of filter one to the VCF 1 crossfader input, and the output of filter two to the VCF 2 crossfader input, so the crossfader output D-OUT is a mix of filter one and two. With the AUDIO MIX control at the 12 'o'clock position a 50\/50 mix of filter one and filter two will be heard, but if the AuDIO Mix is turned to zero (VCF 1) position then only the output of filter one will be heard, and if turned to the VCF2 position then only VCF2 will be heard, and as the AUDIO MIX control can be voltage controlled you can automate cross-fading between the two filters. As an example, using the four way rotary switches you could set VCF1 to LP mode and VCF2 to HP mode, then manually (with the AUDI MIX control) cross fade from a LP to HP filter type, or you could use a 0 to +5V or higher control voltage to do this automatically under voltage control. You could even use the vary outputs for both VCF1 and VCF2 to feed the crossfader, so it is possible to continually vary the individual filter type at the same time as cross fading between filters one and two!\u003c\/p\u003e \u003cp\u003eINVERTED Parallel (Dual) Mode: The mode toggle switch should be set to CASCADE position, and the INVERT switch set to INVERT position to select this mode.This is the same as Parallel mode (above) however the output of VCF2 is inverted before being sent to the crossfader VCF2 input, so VCF 2 is inverted against VCF1, which causes phase cancellations between the two filters when they are mixed together.\u003c\/p\u003e \u003ch3\u003eVersatile Central Mixing BUS\u003c\/h3\u003e \u003cp\u003eThe central mixing bus comprises control knobs for Audio MIX, Dual frequency control level (D-FCV) and Dual FCV mixing (D-FCV Mix), and it includes two CV Inputs, MIX CV input which allows voltage control of audio crossfading of the outputs of VCF1 and VCF2. There is also the D-FCV Input, which allows a dual frequency control voltage to be sent to both VCF1 and VCF2 simultaneously (or if no external CV is patched in it includes a, the amount being controlled by the D-FCV level control, and the amount sent to VCF1 and VCF2 can be controlled by the D-FCV Mix control. With D-FCV MIX in the center position, an equal amount of frequency control voltage from the D-FCV input is routed to both VCF1 and VCF2, however if the D-FCV MIX is turned fully anti-clockwise then the incoming D-FCV voltage will be routed to VCF1 frequency only, likewise with the D-FCV MIX control fully clockwise all of the D-FCV control voltage is routed to VCF2.\u003c\/p\u003e \u003cp\u003eIf no patch cable id plugged into the D-FCV Input socket then an internal voltage source is applied to the D-FCV Level control, so that Manual adjustment of the D-FCV Level control will change the frequency of one or both filters, again depending upon the setting of the D-FCV MIX control. This is very useful as it allows the cut-off frequency of both filters to be adjusted in varying mix amounts from a single control knob.\u003c\/p\u003e \u003ch3\u003eSelf Oscillation\u003c\/h3\u003e \u003cp\u003eThe vintage SEM filter is a beautiful sounding and very versatile filter with an unmistakeable sound, however it was not capable of self oscillation at high Resonance settings, so could not be used as a sine wave oscillator, nor could self oscillation be added to an input signal. As this is a useful addition AJH have added two jumpers to the rear panel, and it can be independently selected for each filter, so for example VCF1 could be configured as a vintage style SEM, whilst VCF2 could have self oscillation ability added, or both VCF's could have it added as desired.\u003c\/p\u003e \u003cp\u003eIn self oscillation mode the filter will track 1 V\/Octave reasonably well over a four octave range, but because the tracking is not temperature compensated it may be necessary to use a module such as the V-Scale buffer to allow the 1V\/Octave tracking slope to be slightly changed to get it to track perfect octaves. The sine wave produced is not perfect, it has a very slight asymmetrical shape which can add very low levels of harmonics, however t still sounds pretty similar to a perfect sine wave.\u003c\/p\u003e \u003cp\u003eIt should be noted that when self resonant mode is selected the output signal becomes considerably higher (hotter) than the usual 10 V p\/p Eurorack level, so if the filter output is being fed into modules downstream (such as a VCA, Ring Modulator etc) then the input level control on this downstream module should be attenuated to prevent it from being overloaded and creating clipping distortion.\u003c\/p\u003e \u003ch3\u003eOverdrive Mode\u003c\/h3\u003e \u003cp\u003eSometimes it can be nice to overdrive a filter to get a fatter, more distorted sound - so AJH have built this facility in too and it is part of the Input level control function.

It features three parametric Equalizers with a massive ±24 dB range, with variable Q - which increases with frequency gain\/attenuation. The parametric EQ bands cover the following ranges: LOW Band 25 Hz to 110 Hz, LO-MID Band 110 Hz to 700 Hz, and HI-MID Band 500 Hz to 2 kHz. The LOW Band also has a switch to select between peak and shelving EQ profiles. There is a fourth HIGH band, which again gives ±24 dB of gain, and this has switchable 2kHz or 5 kHz Shelving. The EQ section can be bypassed with the EQ-On switch, so it is quick and easy to hear the effect of the EQ profile compared to the untreated signal. The equalizer section is a Mono effect and works on the L\/MONO Input only\u003c\/p\u003e \u003ch3\u003eEnhancer Section\u003c\/h3\u003e \u003cp\u003eThe Enhancer\/Maximizer section is a fully analog circuit which adjusts the phase\/time shifting and amplitude on the treated signal to change the levels of fundamental and harmonics. The Enhancer\/Maximizer was originally designed to correct phase and amplitude distortion in speaker systems, so that the resultant sound would more accurately recreate the source sound and correct for the time distortions introduced by speaker systems. However, they can and do go beyond the original brief and are often used as a creative effect to deliberately add punch, bite and extra clarity to source sounds. The ENH-Lo covers the lower band and the ENH-HI the higher bands, they are different from regular tone controls and EQ because, rather than just boost or attenuate particular frequency bands they are a very useful \"finalizing\" tool. The ENH-ON toggle switch is a bypass switch, so again it is very easy to have an a\/b comparison against the untreated source sound. The Enhancer \/ Maximizer section of the Finaliser R-EQ is downstream of the equalizer section, so if the EQ and Enhancer are selected then the eq treated signal is fed to the Enhancer\/Maximizer input.\u003c\/p\u003e \u003ch3\u003eReverb\u003c\/h3\u003e \u003cp\u003eKeep it simple was the philosophy AJH adopted with the reverb, no hunting through sub menus and tweaking hundreds of parameters, just seven switchable reverb types that can be selected using a rotary switch.

Very easy control of the wet\/dry mix too - either manually with the reverb control knob, or by using a CV voltage patched into the REV-CV Input, in which case the Reverb control becomes an attenuator for this control voltage, so that it can accommodate a wider range of control voltages. With the reverb control fully clockwise a 0 to +5 V control voltage range will give full wet\/dry control.

It features three parametric Equalizers with a massive ±24 dB range, with variable Q - which increases with frequency gain\/attenuation. The parametric EQ bands cover the following ranges: LOW Band 25 Hz to 110 Hz, LO-MID Band 110 Hz to 700 Hz, and HI-MID Band 500 Hz to 2 kHz. The LOW Band also has a switch to select between peak and shelving EQ profiles. There is a fourth HIGH band, which again gives ±24 dB of gain, and this has switchable 2kHz or 5 kHz Shelving. The EQ section can be bypassed with the EQ-On switch, so it is quick and easy to hear the effect of the EQ profile compared to the untreated signal. The equalizer section is a Mono effect and works on the L\/MONO Input only\u003c\/p\u003e \u003ch3\u003eEnhancer Section\u003c\/h3\u003e \u003cp\u003eThe Enhancer\/Maximizer section is a fully analog circuit which adjusts the phase\/time shifting and amplitude on the treated signal to change the levels of fundamental and harmonics. The Enhancer\/Maximizer was originally designed to correct phase and amplitude distortion in speaker systems, so that the resultant sound would more accurately recreate the source sound and correct for the time distortions introduced by speaker systems. However, they can and do go beyond the original brief and are often used as a creative effect to deliberately add punch, bite and extra clarity to source sounds. The ENH-Lo covers the lower band and the ENH-HI the higher bands, they are different from regular tone controls and EQ because, rather than just boost or attenuate particular frequency bands they are a very useful \"finalizing\" tool. The ENH-ON toggle switch is a bypass switch, so again it is very easy to have an a\/b comparison against the untreated source sound. The Enhancer \/ Maximizer section of the Finaliser R-EQ is downstream of the equalizer section, so if the EQ and Enhancer are selected then the eq treated signal is fed to the Enhancer\/Maximizer input.\u003c\/p\u003e \u003ch3\u003eReverb\u003c\/h3\u003e \u003cp\u003eKeep it simple was the philosophy AJH adopted with the reverb, no hunting through sub menus and tweaking hundreds of parameters, just seven switchable reverb types that can be selected using a rotary switch.

Very easy control of the wet\/dry mix too - either manually with the reverb control knob, or by using a CV voltage patched into the REV-CV Input, in which case the Reverb control becomes an attenuator for this control voltage, so that it can accommodate a wider range of control voltages. With the reverb control fully clockwise a 0 to +5 V control voltage range will give full wet\/dry control.

Secondly, the re-trigger behavior is quite unique, multiple retriggering increases the output level so that either the volume increases incrementally or the filter opens incrementally with each extra key press.\u003c\/p\u003e \u003cp\u003eAJH have added independent Decay switches for each individual Contour Generator rather than the shared switch on the original synthesizer, these switches change the Contour response from AD (switch up) to ADSD mode (switch down).\u003c\/p\u003e","brand":"AJH Synth","offers":[{"title":"Default Title","offer_id":44450432548967,"sku":"120245","price":246.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/ajh-minimod-dual-contours-black_100095_1_1_33ad4c0a-8a5a-42f0-9d27-5150e8e09a20.jpg?v=1787093041"},{"product_id":"ajh-synth-minimod-vcf-black-demo-deal","title":"AJH Synth MiniMod VCF Black (Demo Deal)","description":"\u003cp\u003eThe stuff of legends, the Moog transistor ladder filter changed the face of the musical landscape forever.

This particular diode ladder filter was originally developed by Eugene Zumchak (a former Moog employee) as a \"work around\" of the original patent (held by Dr Bob Moog) for the transistor ladder filter - the diode ladder was considered sufficiently different that it did not infringe the patent at the time.
