Tecpro Y-Split?

[waster]

Got a 3 way tecpro psu box. Want to know whether the following will work.

 

Two channel Beltpack - Output A in to a Y-Split and then into Output A on PSU. Other end of Y-Split goes to Postion A. Output B same thing into Ouput B on PSU. Other end of Y-Split goes to Position B.

 

PSU outputs B+C linked so output C goes directly to Position C. All other packs are single channel.

 

Will this work?

It may be just me, but what are you trying to do here?

If your beltpacks are 2 channel, but with 2, XLR3 inputs rather than the XLR6 in & out then yes you will need a Y splitter to daisy chain multiple packs together, but I just can't grasp the concept of what you are actually saying in the post.

I ASSUME that you want to do the following:

 

Asuming that the beltbacks are BP112's (Seperate Ring A and Ring B inputs on XLR3)

Comms Ring A:

From PSU output A, through a Y split at the PSU, going out to 2 Beltpacks via seperate cables, connected to the Ring A input (Y split is 1 in, 2 out)

Comms ring B:

From PSU output B, through a Y split at the PSU, going to the same 2 beltpacks, connecting to Ring B inputs.

Output B+C are internally linked on the PSU, so the third beltpack, will recieve only Ring B comms.

 

If you have BP113's, then just daisy chain the whole thing together, looping from one pack to the next.

I'm trying to run two seperate circuits with out having to use a master station due to budget.

 

Let me try and explain again. I was hoping to use the two channel belt pack to be the master in the system for the guy thats running the production to be able to talk to people on two different circuits. All other belt pack are single channel.

 

So I want to know whether a Y-Split from Output A of the PSU, with on end going to the two channel pack and one end going to the single channel pack will work? The second channel of the two channel pack is connected in a similar way to Output B on the PSU, with one end of the Y-Split going to the two channel pack and the other going to a single channel pack. This way there are people out in the room on two seperate circuits (sound and video). Then on the PSU I want to link Outputs B & C so that I can run comm to a third single channel station, but that is on circuit two of the two channel pack.

 

I can't try this as I don't have a two channel pack at the moment. But if it works I will get a two channel pack.

If it's one type of 2 channel belt pack, there will be two inputs and two outputs. The two inputs are likely to be on one plug (6 pin XLR...) so you might need to make up a 2x 3pin XLR to 6pin XLR lead, ditto with the ouput. Use the built in 'link outs' instead of making a passive Y-split. Also the PSU would have to be of the two channel variety, which you suggest it is.

I don't think it's that simple. I tried this with a clearcom beltpack last week, and it didn't work properly without a connection to the master station. Something to do with line termination perhaps?

[adamharman]

Tecpro will run without a master station, and I'm fairly sure it's ok to Y split the cables. They make a splitter box, but I've never had any problems with just splitting them.

 

Are you hiring the gear? I would have thought the cost of hiring the psu and an extra beltpack wouldn't be much less than hiring a master station?

[david.elsbury]

No problems with "just splitting them", agreed. However it seems the OP wants to run just the A channel of the beltpack from the power supply, and link the B channel on to another series of beltpacks, without having to use a master station.

It's fine to split tecpro lines, using a common power supply line, and using two comms lines - but you must make sure the line is not floating. The Tecpro 3 utput psu enables the three outputs to be linked, or separate, and the line resistor in part of the design. If you use two of the outputs to provide the two separate comms lines down the 6 way XLR if that's what you want to do. There are two types of dual circuit pack, the BP112 which uses two separate 3 pin XLRs and has a single volume control and female type sockets. This lets you work on channel 1 OR channel 2. The BP115 lets you talk/listen to 1 AND/OR 2 andhas 6 pin sockets wired for looping - one male, one female.

 

If you use the version that has two female sockets, you do not have loop through, so you'll have to make up splitters or some kind of star system to let them work.

 

So you could use your 3 output psu, using the link switches off - then using the audio lines, split and sent wherever you want, along with the power line. As long as the lines are terminated at the psu, they should be stable. If you break the audio line as it goes to the packs, the un-terminate section will probably suddenly get very loud and screetch like mad. The only complicated bit is just putting XLRs into boxes, and doing a bit of wiring.

Thanks for the info guys.
