Cwejman SFH-1

Post by The Disquiet » Fri Jan 17, 2014 7:42 am

Is the Cwejman SFH-1 discrete or digital ? I assume the latter?

Are there any discrete frequency shifter out there (regardless of the format) other than the Modcan 39B ?

the FSH-1? it's all analog. and sounds terrific.

All Cwejman are analogue, so is the FSH-1.
Best freq shifter I ever heard (as in the most appealing sound)
NOISE HEALS.
patch responsibly.

Cool, has anyone ever compared it with the Modcan 39B ?

not that i'm aware of, although navs did a shoot out with a E560.

here's the fsh-1 in use as a stereo phaser.

i think my fsh-1 gets noisier with time...
just to be sure that i'm not complaining about a problem which isn't one...
do people with an fsh-1 experience noise? does the noise get louder with feedback patches (output into in)?
is some noise to be expected with an analog freq shifter?

i had such crazy bad luck with so many cwejman modules.
i really really hope i don't have to send this one in (5th module :deadbanana: :deadbanana: :deadbanana: )

I don't have a Cwejman but I do have a DACS Freque II, and my first thought when you mention noise and feedback patches is the input level. So I would make sure you are sending the feedback into the attenuated input and try adjusting that level as well as checking the level of the original input signal, which you may also need to attenuate before sending it to the FSH-1 if it's too hot.

thanks, yes i do that and i'm aware of hot levels, the fsh-1 can easily clip. i'm not talking about that noise however, more white noisy and a feedback just makes it more pronounced but it's there without it too.
actually it's the noisiest module i have, some wavefolders are noisy too but the fsh-1 gets them all and i truly think it gets worse over time... :despair:

Ok, then I'm afraid I can't be of much help other than to say that so far I haven't noticed anything like that with the Freque II, which is also analog, although not a eurorack module.

have mine since 4 years in heavy use. no noise. since I upgraded my psu because of noise issues I pay some attention to noise and found all my cwejmans to be extremely quiet.

ok thanks that's what i (not) wanted to hear...at least now i'm sure something is wrong. i know it's not a psu problem and all other cwejman gear is dead silent!
so i guess it's broken, i will email cwejman.
gosh but seriously, i must be extremely unlucky. 5 of my cwejman modules had problems :waah: :waah: :waah:

just looked up the freque II .... my eyes :emt: :emt: !! but it sounds amazing!

Wow, I don’t think I’ve ever seen anyone mention the freque before. I have the original version. Do you ever use yours with the modular? Can it take modular signals directly? I know the cv would be fine but I wasn’t sure about the audio inputs so I never tried.

I just got mine recently but yes, I have it hooked up to my eurorack system. As you know it has 1/4" jacks for everything, but I just got some 3.5mm to 1/4" cables and it works great. I just have it sitting on a TV tray near my eurorack, so no need for a breakout or anything. The Freque II has onboard input attenuators for audio and carrier signals so yeah, it can take modular signals with no problem, you just typically have to attenuate them a bit, but that's often true of other frequency shifters as well. The thing that's great about it that I don't think hardly anyone is aware of, as it's not explained well in the manual (in fact, the manual makes it sound like it can't do this), is it can accept external carrier signals in place of the internal oscillators not only for ring modulation but for frequency shifting as well. So if you have a Doepfer A-110-4 for instance, you can disable the internal oscillators and send the sine to the MOD1 input and the cosine to the MOD2 input (atttenuating them with the onbaord attenuators), and now you have a thru-zero analog frequency shifter with a huge range and separate up/down outputs that can track 1V/oct if you like. And if you want to use other waveforms, something like the Malekko Richter Osc II could serve as the carrier as well (although it wouldn't be thru-zero of course).
