The module is compact at only 6HP and very shallow, making it an easy install in various travel and performance cases. Features a golden (ENIG coated) panel.\u003c\/p\u003e\n\u003cp\u003eThe module has two sets of stereo inputs, which correspond to channels A and B, as well as a stereo output. The two channels are mixed together through the crossfader, and are then passed into the DJ style filter before leaving the module.\u003c\/p\u003e\n\u003cp\u003eCrossfader is controlled using the FADE knob. A switch just below the knob adjusts the volume curve between logarihtmic when flipped to the left or linear when flipped to the right. Logarithmic curve is more popular among DJs, while the linear curve is a more standard shape in passive crossfaders. The crossfade can also be controlled using CV through the FADE jack. An input of -5V will give 100% A channel, while an input of +5V will give 100% B channel. The FADE knob can be used as an offset when using the CV input.\u003c\/p\u003e\n\u003cp\u003eOutput of the crossfader is fed into the DJ style filter. The filter is based on Thomas Henry's VCF circuit, but modified to fit this use case. Cutoff is controlled using the CUT knob. The knob has a center detent for easier live performance. This is where the filter is completely open. As the knob is turned to the left, the signal gets lowpassed. As the knob is turned to the right, the signal gets highpassed. Resonances of LP and HP are controlled separately using the two RES knobs. Note that the filter itself is always active even when in neutral position, so resonance adds some coloration to the sound. Because of this, resonance knobs can be used as a sort of equalizer for the overall sound, even when the cutoff is in neutral position. Cutoff can also be controlled using CV through the CUT jack. An input of -5V will fully lowpass it, while an input of +5V will fully highpass it. Similar to the crossfader, the CUT knob can be used as an offset when using the CV input.\u003c\/p\u003e\n\u003cp\u003eFinally, the module also has a set of two red LEDs which flash when clipping is expected on the output. Internally, the module halves the volume of both channels to prevent internal clipping, and then boosts it back up on output. Some clipping can occur though when mixing two loud signals together or when high resonance is involved. The LEDs help in those cases.\u003c\/p\u003e\n\u003cp\u003eWebsite Page: \u003ca href=\"https:\/\/avalon-harmonics.com\/module\/MiniDJ\/\" target=\"_blank\" rel=\"noopener\"\u003ehttps:\/\/avalon-harmonics.com\/module\/MiniDJ\/\u003c\/a\u003e\u003cbr\u003eModularGrid Page: \u003ca href=\"https:\/\/modulargrid.net\/e\/avalon-harmonics-minidj\" target=\"_blank\" rel=\"noopener\"\u003ehttps:\/\/modulargrid.net\/e\/avalon-harmonics-minidj\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e- Stereo crossfader with adjustable curve\u003cbr\u003e- Stereo DJ style filter\u003cbr\u003e- Separate LP and HP resonances\u003cbr\u003e- CV inputs for crossfader and filter\u003cbr\u003e- Fully analog circuitry\u003cbr\u003e- Clipping LEDs for output\u003cbr\u003e- Wrong polarity protection\u003cbr\u003e- Skiff friendly\u003cbr\u003e- Size: 6HP\u003cbr\u003e- Depth: 26mm\u003cbr\u003e- Power: +12V: 93mA, -12V: 89mA\u003c\/p\u003e","brand":"Avalon Harmonics","offers":[{"title":"Default Title","offer_id":57944565776758,"sku":"AH0018PS","price":25.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0996\/5250\/1878\/files\/MiniDJ_PCB-Sqr.png?v=1779721371"},{"product_id":"avalon-harmonics-kickaid-pcb","title":"Avalon Harmonics KickAid PCB Set","description":"\u003cp\u003eThis article is for a set of empty PCBs used for building Avalon Harmonics KickAid yourself. \u003cstrong\u003eDOES NOT CONTAIN ANY COMPONENTS.\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eNOTE: This build requires soldering a very tiny BCM847BS SMD dual transistor package.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eGitHub BOM \u0026amp; Source: \u003ca href=\"https:\/\/github.com\/Thorinair\/Avalon-Harmonics\/tree\/master\/Modules\/KickAid\" target=\"_blank\" rel=\"noopener\"\u003ehttps:\/\/github.com\/Thorinair\/Avalon-Harmonics\/tree\/master\/Modules\/KickAid\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003cbr\u003e1x Avalon Harmonics KickAid Panel PCB\u003cbr\u003e1x Avalon Harmonics KickAid Front PCB\u003cbr\u003e1x Avalon Harmonics KickAid Main PCB\u003c\/p\u003e\n\u003cp\u003eKickAid is a module designed to help with various stages of processing kick rumble. It helps with amplifying an external kick instrument, automatically detecting the kick, performing ducking on a reverb from a send and return, equalizing the kick and rumble, and mixing them together. Note that the module still requires a kick source and a module that can provide the reverb effect.\u003c\/p\u003e\n\u003cp\u003eFirstly, a kick source should be connected to the IN jack. Module can accept either a Eurorack level kick or one from an external instrument. The up-most GAIN knob can be used to amplify the incoming signal up to 17 times if necessary. Amplified kick is then sent to the SEND jack, which should be connected to a reverb module of choice. Output of the reverb module should be connected back to the RTRN jack.\u003c\/p\u003e\n\u003cp\u003eOnce these connections are achieved, module can be used for its intended purpose: creating kick rumble. Kicks will stimulate a ducking effect on the reverb signal and thus create a sidechain effect. Both kick and rumble can be tilt-equalized separately using the EQ KICK and EQ FX knobs. The two signals can then be crossfaded using the MIX knob in the center. Final output is available on the OUT jack. Note that the output is AC coupled so it can only be used for audio signals.\u003c\/p\u003e\n\u003cp\u003eThe module allows for very fine control of the ducking behavior using six potentiometers and a switch, as well as monitoring of the behavior using four LEDs.\u003c\/p\u003e\n\u003cp\u003eTo achieve the ducking, the following processing chain is performed:\u003c\/p\u003e\n\u003cp\u003e1. The kick is first rectified with the status visible on the K LED.\u003cbr\u003e2. The rectified signal is then passed through an envelope follower, and the result is visible on the F LED. Smoothing of the follower can be adjusted using the FALL pot. The follower can be overriden with an external signal by plugging a cable into the EXT jack.\u003cbr\u003e3. The output is then passed through a thresholding circuit. Using the THRS pot, a trigger and gate signal is generated when the value is above the set threshold, with the gate shown on the G LED. Outputs of the trigger and gate are also available on the TRIG and GATE jacks. Behavior of the gate can be changed using the switch in the middle. When set to the left, gete is open when the value is above the threshold. When set to the right, the gate will have a static length set by the LENG pot.\u003cbr\u003e4. Finally, the gate is inverted and used to generate a ducking envelope. Attack can be set using the ATCK pot and decay using the DECY pot. Intensity of the ducking can be adjusted using the DUCK pot. Status is visible on the E LED. This envelope is used to duck the rumble, and is also available as an envelope on the ENV jack.\u003c\/p\u003e\n\u003cp\u003eThe module's primary purpose is for creating kick rumble, but can also be used for various other things. For instance, it can be used to duck basslines against a kick simply by plugging the bassline into the RTRN jack. Or it can be used to create big reverbs which fade in after a synth lead. The TRIG output can also be used to drive the clock of the rack based on a four-on-the-floor kick beat coming from an external instrument. The possibilities are only limited by the creativity of the operator!\u003c\/p\u003e\n\u003cp\u003eWebsite Page: \u003ca href=\"https:\/\/avalon-harmonics.com\/module\/KickAid\/\" target=\"_blank\" rel=\"noopener\"\u003ehttps:\/\/avalon-harmonics.com\/module\/KickAid\/\u003c\/a\u003e\u003cbr\u003eModularGrid Page: \u003ca href=\"https:\/\/modulargrid.net\/e\/avalon-harmonics-kickaid\" target=\"_blank\" rel=\"noopener\"\u003ehttps:\/\/modulargrid.net\/e\/avalon-harmonics-kickaid\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e- Kick rumble processor with tons of features\u003cbr\u003e- External amplification up to 17 times\u003cbr\u003e- Kick and rumble equalization\u003cbr\u003e- Kick and rumble mixing\u003cbr\u003e- Kick detection with trigger and gate outputs\u003cbr\u003e- Ducking envelope generator with envelope output\u003cbr\u003e- LED monitoring of the envelope stages\u003cbr\u003e- Usable for things beyond just kicks\u003cbr\u003e- Wrong polarity protection\u003cbr\u003e- Size: 8HP\u003cbr\u003e- Depth: 36mm\u003cbr\u003e- Power: +12V: 46mA, -12V: 41mA\u003c\/p\u003e","brand":"Avalon Harmonics","offers":[{"title":"Default Title","offer_id":57944565907830,"sku":"AH0013PS","price":20.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0996\/5250\/1878\/files\/KickAid_PCB-Sqr_88fcfed1-dd19-4297-8fcc-97452ca62ec3.jpg?v=1779723428"},{"product_id":"avalon-harmonics-ivca-pcb","title":"Avalon Harmonics iVCA PCB Set","description":"\u003cp\u003eThis article is for a set of empty PCBs used for building Avalon Harmonics iVCA yourself. \u003cstrong\u003eDOES NOT CONTAIN ANY COMPONENTS.\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eNOTE: This build requires soldering a very tiny BCM847BS SMD dual transistor package.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eGitHub BOM \u0026amp; Source: \u003ca href=\"https:\/\/github.com\/Thorinair\/Avalon-Harmonics\/tree\/master\/Modules\/iVCA\" target=\"_blank\" rel=\"noopener\"\u003ehttps:\/\/github.com\/Thorinair\/Avalon-Harmonics\/tree\/master\/Modules\/iVCA\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes:\u003c\/strong\u003e\u003cbr\u003e1x Avalon Harmonics iVCA Panel PCB\u003cbr\u003e1x Avalon Harmonics iVCA Front PCB\u003cbr\u003e1x Avalon Harmonics iVCA Main PCB\u003c\/p\u003e\n\u003cp\u003eiVCA is a simple stereo VCA, with a focus on manipulating the incoming CV by allowing for full range offsetting and attenuverting. The VCA circuits are a classic simple transistor type.\u003c\/p\u003e\n\u003cp\u003eThe L and R IN jacks accept an incoming audio signal, while the L and R OUT jacks are for the output. The inputs have around 14 Vpp capacity and are best suited for audio signals. VOL knob can be used to adjust the volume of the incoming signals and can be used to tame very loud signals if necessary. When set above around 3 o'clock, the signals will have some additional gain applied to them.\u003c\/p\u003e\n\u003cp\u003eThe main focus of the module is to allow for easy manipulation of the control signal. OFS knob can be used to offset the CV signal in a full range into both positive and negative values. It can also be used to fully open the VCA when turning it all the way clockwise. ATN knob is an attenuverter for the CV signal. The signal has no effect when set to the middle, has around 2x the effect when set all the way clockwise, and around 2x the inverted effect when set all the way counter-clockwise. This allows the module to be easily adjusted to behave like a normal VCA to control notes, or as a ducking effect to do some sidechain action.Thanks to the multiplied CV input, the VCA can fully open even with a 5V CV input.

The input that can be sampled and can range from around 10V to -4.5V. If the value is outside this range, it will be clipped but won't damage the module. Note that the sampled value will slowly drop down with time towards around -6V, so if sampling 1V\/OCT, it is best to use it for shorter notes.\u003c\/p\u003e\n\u003cp\u003eIt can also perform sampling from a built in random source. This allows it to be used as a randomizer. The random source generally generates values between -2.5V and +2.5V, but can randomly assume any value within the sampleable range.

Source of the sampled values can be chosen with the top-most switch.\u003c\/p\u003e\n\u003cp\u003eSampling speed can go all the way into high audio rates, allowing the module to be used as a sort of sample crusher effect.

The VU display consists of 5 yellow, 3 orange, and 2 red LEDs. The module provides an input jack on the bottom, and a buffered output jack on top, allowing it to be placed right before the master output if so desired. Note that there is no AC coupling, so the module can also be used with slow moving CV signals if so desired.\u003c\/p\u003e\n\u003cp\u003eVU meter can be in either bar or dot mode. This is selected by placing a jumper on the PCB. Leaving the jumper on puts the display in bar mode. The response curve of the VU display depends on the inserted LED driver chip. Three variants of the chip exist and are interchangable on the PCB. The compatible chips are:\u003cbr\u003e- LM3914 - Linear response curve\u003cbr\u003e- LM3915 - Logarithmic response curve, each LED is 3dB\u003cbr\u003e- LM3916 - VU meter response curve, each LED corresponds to following dB levels: +3, +2, +1, 0, -1, -3, -5, -7, -10, -20\u003c\/p\u003e\n\u003cp\u003eIn order to drive the the VU display, the signal is first precision rectified, and then passed through an envelope follower. The falloff of this envelope can be adjusted using the HOLD knob, from virtually instantaneous falloff, to a few seconds long one. This envelope follower CV signal is also available on the PEAK output jack, and can be used to control any other module, for instance, to create a sidechain effect. Its voltage ranges from 0V to 9V, depending on the input signal and the set gain (see below).\u003c\/p\u003e\n\u003cp\u003eIn order to make the module compatible for different rack setups, a trimmer on the PCB (T_GAIN) allows you to adjust the internal gain of the envelope follower input. This allows you to adjust the VU meter so it hits the peak exactly when it would usually clip on the output module, or whatever is after it, ensuring a more accurate display. This gain does NOT affect the buffered output.\u003c\/p\u003e\n\u003cp\u003eLastly, the brightness of the last LED can be adjusted with a trimmer on the PCB (T_LED).

R IN jack is normalled to the L IN jack when nothing is plugged into it, allowing to expand a mono signal to stereo. Note that the audio output is AC coupled so it cannot be used for passing CV signals. The inputs have around 14 Vpp capacity. IN GAIN knob can be used to adjust the gain of the incoming audio signal and can be used to tame very loud signals if necessary.

ATN knob allows for attenuverting the signal, making it possible to invert it, while OFS knob adds an offset voltage from -5V to +5V. These two knobs together create a CV mix, which has a different use depending on the mode that the module is in.\u003c\/p\u003e\n\u003cp\u003eIn VCA mode, the module is a stereo VCA so both left and right CV are coupled together. At +5V CV, ATN set all the way clockwise, and IN GAIN knob set at 3 o'clock, output will be at unity gain. The CV mix can however exceed the 5V (either by adding offset to the CV signal, or by applying a higher signal), allowing for up to 2x volume on output. Thanks to the versatility of ATN and OFS knobs, the module can behave like a normal VCA, or as an inverted VCA, allowing for easy trance gate effects and more.\u003c\/p\u003e\n\u003cp\u003eIn PAN mode, left and right channels are fully open by default, while left and right CV are inverted from each other.

CV input, combined with ATN knob can be used to automate panning of the signal left\/right and adjust the intensity of the effect, best used with an LFO.

This envelope follower CV signal is also available on the PEAK output jack, and can be used to control any other module, for instance, to create a sidechain effect. Its voltage ranges from 0V to 9V, depending on the input signal and the set gain (see below).\u003c\/p\u003e\n\u003cp\u003eIn order to make the module compatible for different rack setups, a trimmer on the PCB (T_GAIN) allows you to adjust the internal gain of the envelope follower input. This allows you to adjust the VU meter so it hits the peak exactly when it would usually clip on the output module, or whatever is after it, ensuring a more accurate display. This gain does NOT affect the buffered output.\u003c\/p\u003e\n\u003cp\u003eLastly, the brightness of the last LED can be adjusted with a trimmer on the PCB (T_LED). The brightness can range from around same brightness like all other LEDs, to much brighter.

If a need arises for an audio mixer, setting offsets to unipolar mode and sliding them all the way down will achieve this kind of behavior.\u003c\/p\u003e\n\u003cp\u003eLastly, a bipolar LED exists for each channel as a clear indicator of the status of the output voltage.\u003c\/p\u003e\n\u003cp\u003eWebsite Page: \u003ca href=\"https:\/\/avalon-harmonics.com\/module\/CVModH\/\" target=\"_blank\" rel=\"noopener\"\u003ehttps:\/\/avalon-harmonics.com\/module\/CVModH\/\u003c\/a\u003e\u003cbr\u003eModularGrid Page: \u003ca href=\"https:\/\/modulargrid.net\/e\/avalon-harmonics-cvmodh\" target=\"_blank\" rel=\"noopener\"\u003ehttps:\/\/modulargrid.net\/e\/avalon-harmonics-cvmodh\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e- 2 independent channels\u003cbr\u003e- Offset for both channels with a polarity switch\u003cbr\u003e- Both channels with an input and attenuverter\u003cbr\u003e- Togglable forwarding of output to second channel\u003cbr\u003e- Status LEDs for both channels\u003cbr\u003e- Wrong polarity protection\u003cbr\u003e- Skiff friendly\u003cbr\u003e- Size: 22HP 1U\u003cbr\u003e- Depth: 25mm\u003cbr\u003e- Power: +12V: 28mA, -12V: 25mA\u003c\/p\u003e","brand":"Avalon Harmonics","offers":[{"title":"Default Title","offer_id":57969334124918,"sku":null,"price":20.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0996\/5250\/1878\/files\/CVModH_PCB-Sqr.jpg?v=1779955086"}],"url":"https:\/\/shop.avalon-harmonics.com\/collections\/pcb-sets.oembed","provider":"Avalon Harmonics","version":"1.0","type":"link"}
