WMD 4tten - 4 channel attenuator and offset

Post by NastyNachos » Wed May 20, 2020 12:33 pm

Our newest module is out and shipping now!

Image

Such a useful little module.

Here's the deets:.

4TTEN (pronounced either ATTEN or FOUR-TEN) is a four channel attenuator and offset generator.

Use 4TTEN to attenuate any CV or audio signal by running through the ins and outs.

A +5V voltage source is normalled to each input, making it a standalone offset when there is no cable patched into an input.

Each channel is completely independent.

Ever-so-useful in live performance, we designed this module with 4 sliders for easy maneuverability, visual feedback, and enjoyable to play interface. Make your eurorack modular synthesizer system more playable with 4TTEN!

*** 4TTEN's PCB is 113mm (4.45") tall and may be a tight fit in some cases ***

Highlights
  • 4 independent attenuators for Control Voltage and Audio signals

    Performance friendly sliders

    Can be used as 0 to +5V Offset

    Comfortable fader caps from the Performance Mixer

    Only 4 hp!
Specs:
Size: 4hp
Depth: 30mm(with cables)
Power: +5mA , -5mA
Virtually no drop on 1V/Oct signals.
VERTICAL PCB LENGTH: 4.45 in
IMPEDANCE
(SOURCE + 100ohm ) / 100kohm
UNBUFFERED

Too bad it only outputs 5 volts. I’m looking for faders for my Muton and this would have been perfect. Back to the MSW F8R plan I guess.
Any chance in 8-10V outputs, Alex?
I know, I know, completely different use cases; attenuater vs cv souce, but a girl can dream.

From the Muton Manual: "A control voltage, such as an envelope with an 8-10V peak will open the VCA completely for unity gain output. Lower voltage CV will also work with a reduction in output volume - in some situations such as mixing, lower volumes may be desired as to alleviate clipping."

So it's probably good with 0-5. If you've verified that you need 8-10V, then we could swap one part for you and do a lil custom jobby. But, you should try first to see if it's totally necessary!

cool. does it have LEDs (can't really tell for sure in the photo) to indicate input or output voltage levels and polarity? will there be a silver panel too?

Yes LEDs, indicates positive voltage. Negative voltage is not indicated by the LED. No silver panel because we are manufacturing panels in house, and we can not make silver panels. The panels are milled and engraved.

Thanks

Brilliant idea! Where can I buy it in the UK?

Voltage and polarity jumpers would be a cool mod

Wow, thanks for the offer, I’ll be in touch. I tried using a 16n with my Muton in this fashion, but the 5v output wasn’t enough to open the vca’s satisfactorily. I could never get my drum mixes just right, mostly the Crater seemed like it was wasn’t getting to deliver it’s all. Faders all up on 16n, and the Crater was underrepresented compared to my 3 other WMD drum modules.
Thanks again Alex! You guys rock.

This is just the module I’ve been waiting for, I love to keep my bottom row accessible. Looking forward!

Received mine today, works as expected, and the faders have a nice feel to them. Just a heads up, as it wasn't immediately clear to me and I haven't seen a manual or a video for this yet - the inputs are the jacks with the letters directly underneath them, and the corresponding output is immediately above each input. The LEDs indicate the input voltage (when it's positive, negative input voltages are attenuated by the faders but do not cause the LEDs to light).

I like the idea of sliders, but not a ton of range being this small compared to a knob. Anyone give it a go and see how easy it is to dial in something exact? Jacks on the top is a win for me given my case situation.

Thanks!

The range of travel is good enough for my purposes. The inputs are normalized to 5V, and dialing in, say, 2.5V or 3V is not hard. I would say they're maybe a hair less range-wise than some of the smaller faders that are on a lot of the Instruo modules if you have any of those.

There's a warning on the WMD/Modular Grid page that the vertical PCB height is 4.45" and that might be a tight fit for some cases. Since it also states that it's 30mm deep, I am interpreting this dimension as the distance from rail to rail, which I would have assumed to be fairly standardized?

If I am understanding correctly, then seems like it would fit in an Intellijel 7u case, but can anyone be a pal and confirm that it does?

Thanks in advance! :party:

Mine was very tight in a custom wood skiff I had but I made it fit. I'm not sure I can get it out to put it in the palette lol.

Fits fine in a palette. It will not fit between Z-rails in my diy case.

Thanks for the responses, I appreciate it! Kinda surprised that it fluctuates that much but good to know.

Purchased it because it was the perfect module I needed (4 attenuators AND 4 offsets in 4hp black panel) only to discover that it wouldn't fit my Erica Synths case :cry: (yes I'm the idiot who missed the warning on the site page).

So I used a file and removed a bit of the aluminium from the rails until it fits.

I absolutely do not regret damaging the case because this thing is so enjoyable! I'm actually using it more as a performance voltage generator than for attenuating (to drive decay or saturation or stuff like that more easily than by turning a knob). It is great value.

4tten fits perfectly in the Pittsburgh Modular EP-208 case.

Really a great module that has been used in every patch since I got it. The sliders feel great and aren't easily knocked out of place.
