| Filterbank Order Form 
 These will be available about mid/end of July 2010 - taking orders now.
 
 (See http://www.jhaible.de/ffb/fixed_filter_bank.html for details about the project.)
 
 Please note that you will need at least 2 boards (for a 907-like 10-Band Filterbank),
 or 3 boards (for a 914-like 14-Band version)
 
 Pricing is EUR 27.00 per board
 
 plus a single EUR 6.00 shipping flat charge for worldwide shipping,
 
 regardless how many boards you are ordering and where you live.
 
 It does *not* include any customs fees or tax that you may (or may not) have
 
 to pay in your county.
 
 What you get is a double-sided printed circuit board with component overlay,
 
 approx. size 160mm x 100mmm.
 
 You have to buy the electronic components for this, and build the device,
 
 yourself. (Check the above website regularly for updates and building hints,
 
 bill of matrials etc.)
 
 
 If you want to place an order, please send me an email. (no PM, please)
 
 jhaible@debitel.net
 
 and use the FOLLOWING FORM (fill in your data instead of [],
 
 for instance: "2 Boards" instead of "[quantity] Boards")
 
 ===== Start of Email Order Form ===============
 
 Email Subject line: Filterbank: [quantity] boards
 
 Email text:
 
 I'm ordering [quantity] pieces of the Filterbank PCB
 
 for EUR 27.00 per board + EUR 6.00 single shipping flat charge for any
 
 number of boards.
 
 I'm aware that I may have to pay additional amounts of customs and tax in my
 
 country.
 
 I'm also aware that I'm only buying blank PCBs that may help me building an
 
 electonic module - I'm *not* buying a diy kit, not a "project" - just pieces
 
 of FR4 with copper traces.
 
 I know how to build electronic circuits and I am trained in electrical safety matters.
 
 The seller of these PCBs will not be held responsible for any damage that results
 
 from these PCBs, directly or indirectly.
 
 My shipping adress is
 
 [Your Name, your street, number, city, ZIP code, country, in exactly the form
 
 that is generally used in your country, so I just copy and paste it for shipping your package]
 
 
 My paypal adress is [your paypal adress].
 
 I===== End of Email Order Form =========
 
 Looking forward to hear fom you

 I think if the panel is large enough for 14 decent-sized potentiometers you will also find space for 3 PCBs behind it.
 
 For the mechanical construction, I'm of no help personally, but others here on the forum have worked mechanical miracles building beautiful modules from my naked PCBs.

 Haven't made the drawings yet.
 But you can use the active version and calculate them from the NIC capacitor values: L = 2200**2 * C

 Many thank on both questions JH. I'm looking forward to these. I'm seriously considering building a passive version to include in my Synthacon ressurection because Nyle never did offer a fixed filter bank, and they are so useful.

| I recommend using a NE5532A opamp instead of the OPA2134 for the 14-band version. (For the summing amplifier only. The GIC filters are built around RC4558.)

| Juergen,if you populate the pcb with discrete driver amplifier and summing amplifier can these parts leaved on the pcb if you dicide to add the opamp based amplifiers option after? |  |

 Yes - you'll notice the jumpers on the PCB.
 For testing, I implemented both, and then just changed the jumpers.
 
 This applies to the small version (2 PCBs). The large version (3 PCBs) works with discrete driver and opamp output amp only. (As you can see, I've mis-used the PCB pattern for an entirely different output amp there.)

 If I remember Sunday schooling right that’s the sigh the Christians used to identify each other in secrete
 This was back in the days when being fed to the lions was what happened to Christians

| Yes, it's an old Christian symbol, an Ichthys. http://en.wikipedia.org/wiki/Ichthys
 
 I experienced a stunning miracle two and a half years ago, when a really severe tinnitus went away within a minute after a prayer to Jesus. I probably wouldn't have any fun designing music-related electronics anymore, otherwise. So I decided to give reference to him on my PCBs with a "Soli Deo Gloria" and that "Jesus-Fish".

| I just got 3 boards (they look great!), and I am ready to start building. Looking forward to implement this into my moog/synthesizers.com modular. I got all the files from Jürgen´s web site, but I can´t find any complete schematics for the 914 (3 board) version. I guess I will manage with the 907 schematics and the add-on, or is there anything else I should be aware of?
 
 Also, why is the 10-channel 907 module more "famous" than the 14-channel 914 module?

 I haven't drawn complete schemos for the 914 version yet.
   I will, I promise.
 You can already build them from the component overlay PDFs I've posted (*not* from the component overlay on the PCBs!!), and the input/output amp schemos are already there also.
 
 I thought the 914  was the more famous one, but the 907 more rare. Not sure about either.

 OK, that is fine by me. I will be patient, and start building from the PDFs.

 That is probably it. The more rare it is, it usually rises to fame.
