Help with Patch Leads, Which do I buy? SOLVED! Thanks to Amo

Post by Seamus4444 » Mon Jan 24, 2005 3:30 pm

Hi, I've just taken delivery of the Voyager, along with a VX-351, and CP-251, plus expression pedal. I'm a bit confused as to what type of patch leads I need, as the manual says (I think) to use Tip/Ring/Sleeve rather than the standard 2 conductor leads. I think what it's saying is that the pedals won't work with 2 conductor leads becauue the pedal voltage won't be carried. Do I need just standard "Stereo" leads?? Alternatively, can anyone tell me how to make my own? Cheers, Shaun.

Right, This is how it is! Straightforward 2 conductor (Tip/Sleeve patch cords) are all that is needed. The only time Tip/Ring/Sleeve is needed, is to connect an expression pedal to the voyager via the red sockets. Since the Pedal comes with Tip/Ring/Sleeve fitted it will work fine. All other connections between voyager, VX-351, and CP-251 use standard Tip/Sleeve two conductor patch cords. Thanks for all your help everone!

Seamus -

You're better off with TRS rather than 2 conductor, simply because TRS will work with either 2 conductor or 3 conductor jacks.

Here in the states, a company called Hosa makes 1/4" molded patch cords in different lengths and colors, including TRS types. Hosa cables aren't the best cable you can buy, but they're not the most expensive either. Not sure if they're available where you are, but I'm certain you can get leads ready-made at your friendly local music store.

Can you make them yourself? Of course! But you need to buy the cable, and two 1/4 plugs for each cable you make. Can get pricey pretty quickly, and your time is worth something as well. Add to that, when you're building your own cables you're not playing with and enjoying your new gear.

My advice (FWIW): Buy 'em if you can, and get several lengths. And buy more than you think you'll need. Once you start patching things up, you don't want to get stopped by a shortage of cords!

BTW - Congrats on the new gear. You're gonna have a lot of fun!

Patch Leads

Post by Seamus4444 » Tue Jan 25, 2005 2:32 am

Hi, and thanks for the reply. I can get cheap crappy moulded TRS leads over here, but i'm a home cinema geek and I have a thing about quality cables, which is why I was thinking of making them myself. I doon't have a problem with the cost, and it wouldn't take me long as i'm pretty handy with that sort of thing, but I wanted to be 100% sure about the connections in theplugs before I spend a lot of money and gold plated plugs and OFC cable, only to blow my Voyager up on first use! For that reason, I would prefer to buy quality leads if I can find them, but if anyone can tell me what the correct way of wiring the plugs is, I may just go for it. (The manual says something about shorting 2 connectors together)??? Cheers, Shaun.

I understand the thing about cables.

Regarding the wiring, the connections are straightforward:

tip <---> tip
ring <---> ring
sleeve <---> sleeve

Not all Voyager connections require TRS-type plugs, but they will work nonetheless. No harm to have all TRS cables in your setup.

Good luck!

Tip Ring Sleeve

Post by Seamus4444 » Tue Jan 25, 2005 2:27 pm

Thanks for the responses, but I've had conflicting feedback. The manual says something about shorting 2 of the conductors in the jack, and the Voyager supplier tells me to use a 1 conductor shielded cable, and only wire the tip and the sleeve, leaving the ring untouched? My gut reaction is to go with the straight forward T/R/S connections as suggested in this thread, but if anyone knows better....

My thanks to those that have responded so far. Shaun.

<< The manual says something about shorting 2 of the conductors in the jack >>

What page in the manual?

Page 26 of the CP251 Manual. I'm not sure i'm reading it correctly though. Here's the text:

Your CP251 will work properly with either two-conductor (Tip-Sleeve) or three-conductor (Tip-Ring-Sleeve) patch cords. If you use two-conductor patch cords, then, as explained above, plugs inserted into the red jacks will simply short the pedal supply currents to ground, with no adverse effects whatsoever to the operation of the CP251. When used with MF-Series devices however, two conductor patch cords will short out the pedal supply current that is available at all pedal/control input jacks. Thus, if you
plug a tip-sleeve phone plug into one of the pedal/control input jacks of an MF-Series device, then none of the pedal/control jacks on that device will be able to supply power to an expression pedal. This is explained in the user’s manual that accompanied your MF-Series device.

If you wish to use your CP251 Control Processor with an MF-Series device and you wish to be able to plug one or more expression pedals into the pedal/control jacks of the device, then your best bet is to purchase or make a set of patch cords with Tip-Ring-Sleeve phone plugs, but do not connect the Ring terminals to anything.[/color] Alternately, you can acquire a set of three-conductor patch cords in which the Ring terminals of the two plugs of each patch cord are connected together. Such cords will not short out the pedal supply currents that are available at the MF-Series pedal/control jacks when the other ends are plugged into most two-conductor phone jacks.

Shaun -

The issue raised in the CP-251 manual applies to MoogerFoogers (MF series) devices, which you don't have.

I re-read your original post. I have the same gear (Vger, CP-251, VX-351 & Expression pedal). My expression pedal isn't Moog, but is electrically identical.

I use two-conductor cords to make connections between the Vger and 251/351 modules with no issues. You could do the same, but no harm for you to use TRS cords, either. If you make 'em yourself, connect T - T, R - R, S - S.

Besides, you can always make specialty cords if you do acquire a MoogerFooger.

Go for it, man!

Patch Leads

Thanks for that, I've decided i'd get better leads if I buy some OFC and decent plugs and make them myself. I don't have a problem with that. You're right, I don't have the moogerfoogers, but I was trying to be sure I got what I needed first time, because they are next on my shopping list. I intend to rack mount them with the CP & VX, along with a blue rack light I picked up recently. Should look great with the AE, and it will keep me busy for years! Cheers, Shaun.

Cool Blue Light?

Post by frederic » Wed Jan 26, 2005 1:49 pm

Where'd you get the blue light? Can I get it for my gooseneck lamp? I have the same set, AE,251,351. The Hosa cables look like a good cheep way to get started and see if everything works. This is gonna be F-U-N.
Oh yea, I'm gonna make a polymoog out of my Alesis QS7. It does SAMPLING!
