#1

Have some fun patching your modular through your favorite stompboxes!

Technical ​Specifications
Pedal I/O​ ​IN​ ​jack:
● Input level = 0 dBV nominal, +17 dBV max
●Input impedance = 60 KΩ
● Gain = -30 dB to -20 dB
● RF filter protected
Pedal​ ​I/O​ ​Jack​ ​SEND​ ​(or​ ​7U​ ​Case​ ​Adapter​ ​OUT):
● Output level = -20 dBV to -30 dbV nominal based on Send Level
● Output impedance = 12 KΩ to simulate the impedance of magnetic guitar pickup
Pedal I/O​ ​Jack​ ​RETURN​ ​(or​ ​7U​ ​Case​ ​Adapter​ ​IN):
● Input level = -20 dBV to -30 dBV nominal based on Return Level
● Input impedance = 1 MegΩ
● Return Gain = fully off to +30 dB
● RF filter protected
Pedal I/O​ ​MIX​ ​jack:
● Output level = 0 dBV nominal, +17dB max
● Output impedance = 100Ω
● Frequency response is 20Hz to 22KHz
● THD = 0.002% to 0.085% at Vin = 0dBV to +17dBV
(Pedal In to Pedal Out, Mix = effect, Return Level = min, Send Level = max)
THD = 0.04% to 4.0% at Vin = 0dBV to +17dBV
(Pedal In to Pedal Out, Mix = effect, Return Level = max, Send Level = max)

all the specs are at the end of the manual

Would you recommend to use the pedal i/o system also as a direct output?

#3

It can be used for that, yes.

#4

Is it possible to use it as vocal microphone input ??

#5

If your mic doesn’t need phantom power then it should work, yes

#6

I understand pedals usually require/have unbalanced ins and outs. But can I use the Pedal I/O module for hardware effects with balanced ins and outs, too? At the moment, trying just that gives me all kinds of noises.

Thank you!

#7

You can use it for balanced line level but you will have one legged signals (i.e. -6dB)

Should be no problems with noise.

is there a way to convert stompboxes and pedals to modules? I’ve seen several youtube videos on the subject, but I couldn’t solder to save my soul…If not you guys, do you know of a company that will do this for you (send in a pedal and a certain amount of money and get a module back)? If so, would you recommend them?

Also, would intellijel ever consider making a module that can do some basic pedal effects? on my shortlist would be: tremolo/wahwah, screamer, distortion/overdrive, fuzz, and maybe a few others. Can the rainmaker do this? I know virtually nothing about it.
I would love to be able to patch the effects into themselves, so maybe could you guys have it be a part of your micro series, and just be able to select only one function, but have multiple modules? I think this would be really cool and would appreciate it a lot.

The Pedal IO is probably the best way to get pedals talking to other modules. It may be possible to convert some pedals, but I haven’t seen too many instances of that. One issue is that the PCBs are usually designed for the pedal form factor and so they’re a lot more spacious than most modules.

We do have some effects that are loosely based on some classic pedal circuits, notably the distortions in a few of our filters like the Morgasmatron.

A tremolo can be achieved by modulating a VCA with an LFO or looping envelope.

Wah/wah can be achieved by modulating a bandpass filter with resonance turned up.

#10

the main reason I don’t want to have external pedals is power. Clutter would also be an issue though…

#11

so is there some simple thing that can convert a eurorack power slot into one or more pedal power plugs?

#12

Not that I know of, but that would be a good idea for a 1U tile

@kamil could we do that for the pedal send/return, or as an expander? I would totally buy that as an updated version!

#14

I’ve added it to the list of 1U module ideas :slight_smile:
