[Order] Continuum Phase Shifter - Fabbed PCBs and Panels |
|
|
This one has been a long time coming! Brand spanking new fabbed PCBs are now in stock. Panels are on order and should arrive within 4 weeks. The panels are 10HP and are basically the same as shown below, with the exception that the 'Frequency Central' logo will be in mirror image.
If you want just a PCB or two you can order now they'll be shipped right out.
If you want PCB + panel you can order now but please allow about 5 weeks for delivery.
Continuum PCB: £15 GBP
Continuum Panel: £15 GBP
Shipping:
Please add £3 GBP if you're outside Europe.
Paypal to:
payments(AT)frequencycentral.co.uk
....don't forget to replace the (AT) with @
Soundclips? First, let's phase some pink noise:

So now, with a couple of VCOs as audio, let's send S/H into one CV input then an ADSR into the other, while slowly turning up the resonance:

Now, a single VCO as audio, with ADSR to one CV input of Continuum, and slowly introducing a -1oct sub osc to the other CV input:

Some Continuum ping action! Using a Roland ADSR to ping it, and a couple of tap tempo LFOs synced with a clock divider to modulate it. There's some serious bottom end going on there, better hook up your playback device to your nearfields...:

Finally, here's how it sounds phasing my RS-09:

Can it do Through Zero Phasing? |

Very cool project - before I order it, I had four small questions.
[note - I feel like the Spanish Inquisition sketch - I started out with 2 questions, but I keep adding more. ]
[note 2- I looked around your website and found the answer to most of my questions - here is the link to the document: ]
http://www.frequencycentral.co.uk/wp-content/uploads/2013/02/Continuum-Build-Doc.pdf
1) I see LM13700s, but are the other ICs anything difficult, or just common op-amp stuff?
Answer - Nope - just plain vanilla components
2) Can this run on +/- 15v?
3) What does the "Even/Odd" switch do?
Answer Regenerates even or odd stages - This would be a nice thing for an audio demo...
4) How many stages does the phase shifter have?
Answer - 4 Stages
Thanks

Hi again,
I noticed in the documentation that you said R46 was related to regeneration, and should not be stuffed.
If I wanted to have a regen control, would it make sense to have a 10K pot in that position?
Thanks

Already has a regen control, 'Res' on my panel = regen
The 10K resistor tames the regen in a somewhat musical way, however if you want wild self oscillation you can reduce the resistor, say 4K7. _________________ http://www.frequencycentral.co.uk/ |

Wouldn't it just need a few static all pass filters configured to give a few usec delay? |
