RNC question

[moresound]

I just recently purchased a RNC hooked it up in the rack and ran it through to the patch bay with all T/R/S cabling.
And it sounds real good!
But then I got to reading the manual and it says not to use T/R/S only T/S or it won't work. But it does .....am I missing something here?

'Won't work ..not 'might not?
It's unbalanced, so maybe you're lucking out and 'rings are just floating or being combined to sleeve at both ends.
Hmm. Now I'm trying to recall if they were doing anything besides I/O there. Probably confusing with 'insert.. Never mind.

The RNC is wired for 1 cable operation if required, You can plug into an insert on a mixer using a TRS to TRS cable and not having to worry about a TRS to 2 TS plugs cable (normal insert cable).

When plugging in using a patch bay a TRS patch bay will work with the one cable and using 1 plug the same as above, but if the patch bay has an in and out plug set up you need to have a TS plugged into the RNC from the patch bay or it will think it's a single cable set up and may not work correctly.

Hope that was clear??

Ackk! Yes. What the hell was I thinking- half RNC half RNP...

Not to clear....I mean on the out put of the RNC if I'm to go out balanced into an other unit using a TRS I'm I in danger of hurting that next unit?
Being that the out put of the RNC is unbalanced wont the cable be summing the connection wrong?

No you are not quite understanding what RNC have done.

The outputs of the RNC are unbalanced TS Jacks. If you go from the unbalanced out to a balanced item next in line the summing will be fine.

The inputs of the RNC are unbalanced but they have set them up so they are TRS With the Tip the input the Ring the Output and the Sleeve as Earth (Common). This is so you can use a single TRS cable for the in and out on the 1 jack, when doing this the output jacks are not used. If you use the TRS 1 cable option you plug a TRS cable into a channel insert and the other end of the cable which is also TRS into the input jack, then No other cables are needed.

If you are not using the 1 TRS cable option, do not go into the Input of the RNC using a TRS plug as the unit will think it needs to supply and output on the ring. Use a TS and the unit switches to an unbalanced input with no output on the ring.

To sum it up use a TR plug into the input and a TS or TRS on the output. Unless you are using the TRS 1 cable for input and output on the 1 (input) jack option.

Cheers

I believe I have it now. The only reason I ask is because I have all the out board effects routed into patch bays and I believe that they are all balanced so I was trying to work around this problem.

Any help with this witendoz?

The actual RNC is not balanced so there is no way (apart form fitting balanced ins and outs mods). However the unit does not need to be balanced, most of my rack gear running through my patch bays are unbalanced due to the console having unbalanced insert points (only megga $ consoles have balanced inserts).

All you need to do is have a balanced to unbalanced lead on the ins, the out will take care of themselves. From the in of the balanced patch bay wire the tip to tip, and the ring and sleeve of the TRS to sleeve of the TS.

Great. thanks Alan .....It's oh so clear now!

Most of my out board gear is English manufactured like Klark Tecnik and Drawmer etc.
And they all are XLR in and out so, the cables for them are all XLR to TRS to the patch bays.
Plus the console is a Yamaha PM1800 series with balanced in and out at the insert points.

So you can see...at times it can get confusing.
~ Waking at night in a cold sweat yelling out TIP, RING, SLEEVE ~ is pretty common.

Yes I thought about the Yamaha's and the balanced inserts, so yours has a insert send socket (TRS balanced) and a insert return socket (TRS balanced), I have used these in the past.

You won't find any problem with using the RNC in unbalanced mode, no extra noise and no loss of signal. While balanced gear is good for reducing induced noise, if the signal run is short and you are not right next door to a radio transmitter there should be no problems.

Yes! Yes! The Yamaha is a great console with tons of options.
This is a full console that hasn't been butchered, for a lot of people sell off the channel strips for boutique micpre strips with EQ.

Talk about radio transmitters......I feel sorry for the township next to mine. There they have a radio station frequency booster from the other side of the mountain and so as when your driving along with your radio on, with in about a mile of it, that is all that you can receive on your car radio from one side of the dial to the other side. ~ a real bummer ~
