xiaoyan Posted September 3, 2012 Report Share Posted September 3, 2012 Sanken COS-11D for Zaxcom TRX900LA, How to wire? Actors take on LA From the body. Excessive force Then mic no signal.... :'( :'( :'( lemo 3p!!! too fragile! Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted September 3, 2012 Report Share Posted September 3, 2012 It's a pretty simple wiring. I have a diagram somewhere at the studio, I'm not there right now, however. When I'm there, if no one else has answered -- and, if I can find it -- I'll post it. Note that some of the earlier serial numbered Zaxcom TRX900 transmitters have a different wiring scheme. You'll find that information in the manual. Quote Link to comment Share on other sites More sharing options...

RadoStefanov Posted September 3, 2012 Report Share Posted September 3, 2012 I feel your pain. I just had 3 sanken lemos malfunctioning after only a month.are you using the screw type? Quote Link to comment Share on other sites More sharing options...
xiaoyan Posted September 3, 2012 Author Report Share Posted September 3, 2012 Thank you John. "are you using the screw type?" yes. Quote Link to comment Share on other sites More sharing options...
rich Posted September 3, 2012 Report Share Posted September 3, 2012 the screw in ones like you have in the picture dont have a very good system to prevent pulls on the cable from affecting the soldered part of the connector - its just a crimped bit of metal gripping the cable. the push / pull connector, whilst being slightly longer and thinner which makes it seem more fragile, though i have had no issues in 2 years, has a far better cable clamp. part number is FGG.00.303. i have also taken to putting a loop of cable secured with i bit of adhesive lined heatshrink to provide more strain relief, after the show my zaxcoms are out on hire on has seen a heavy toll on the connectors, though i think that is entirely due to the cast not taking any care of the microhones.

John Blankenship Posted September 3, 2012 Report Share Posted September 3, 2012 (edited) I've wired up both the screw on type and the push on type. I believe the white wire is connected to pin one along with the shield which must also be connected to the shell of the connector. The black wire then goes to pin 2. EDIT: Ignore what I said above and refer to the diagram linked in the next post. (That's what I get for trying to work from memory <g>.)

rich Posted September 3, 2012 Report Share Posted September 3, 2012 youre halfway there John, the black wire goes to pin 3. http://www.sanken-mic.com/en/qanda/index.cfm/11.53 Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted September 3, 2012 Report Share Posted September 3, 2012 <It's a pretty simple wiring.> LOL!! I can't figure out why this is funny, but I guess everything is funny with the right perspective. I, of course, was referring to the simplicity of wiring to two pins of a connector vs some TA5 configurations that require inter-connections to four or five pins along with a resistor.

John Blankenship Posted September 3, 2012 Report Share Posted September 3, 2012 youre halfway there John, the black wire goes to pin 3. http://www.sanken-mi...index.cfm/11.53 Thanks, Rich, for correcting me. I'd hate to disseminate poor information. I believe I wired via a diagram Trew Audio sent me. I was thinking that the shield was also connected to pin one as well as the shell, but I might be wrong about that. Quote Link to comment Share on other sites More sharing options...
rich Posted September 3, 2012 Report Share Posted September 3, 2012 nope, you are right about the shield being connected to pin 1 and the shell. even though it doesnt clearly show this on the sanken diagram. Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted September 3, 2012 Report Share Posted September 3, 2012 Note that TRX900 transmitters prior to Serial #1314 deployed a different wiring scheme which used all three pins with the bias supplied on pin 2. Quote Link to comment Share on other sites More sharing options...
Chase Yeremian Posted September 3, 2012 Report Share Posted September 3, 2012 I too have had trouble with the screw on connectors. What really sucks is if you can't find someone who can just re-crimp your looking at a ~30 dollar connector :. I think i'll try the push/pull connectors next time around.

Jeff Wexler Posted September 3, 2012 Report Share Posted September 3, 2012 "the push / pull connector, whilst being slightly longer and thinner which makes it seem more fragile, though i have had no issues in 2 years, has a far better cable clamp. part number is FGG.00.303." I have never seen the push/pull type lemo used on a lav mic to connect to a transmitter (either a Sennheiser or Zaxcom transmitter). I have always seen the push in then screw collar type connector used. Since the jack side of the connection, mounted in the transmitter, wants to see the screw on type plug, how does all this work if you use the push/pull type connector?

rich Posted September 3, 2012 Report Share Posted September 3, 2012 there is also a groove in the tx mic connector that works for the push / pull connector. like the audio ltd connector (for those that know that system) Quote Link to comment Share on other sites More sharing options...
John Blankenship Posted September 3, 2012 Report Share Posted September 3, 2012 IIRC, Zaxcom recommends the push-pull type. I think because they say it's easier to ground the shell. I've wired both and had assembly success with both. The advantage of the screw-on type (and not a minor one for a body pack wireless) is that it's not as tall, so there's less chance of damage from leverage against the connector. I think the proliferation of the screw-on type is due in part because they are easier to get. Quote Link to comment Share on other sites More sharing options...

Vasileios, Is there some reason you want to inflict such torment on me? You do know that Lemos are the spawn of the devil? I have a 4 pin duplex Lemo (2 male, 2 female) here that just torments and stares at me. Compared to wiring a Lemo, brain surgery is a walk in the park.

All the screw on connectors I got wired by an usual suspect failed after a month, the push pull still works great.. To be fair I have some screw DPAs wired by the Circ that are still operational. What I dont like about the screw type is that it is hard to repair. The Push pull is a classic Lemo connector. Easy to dissemble and assemble.

I am converting to all push pulls. Will report how they handle on the long run. What I like about them is how fast you can wire a talent.
