wedding venue connections

[Kilwox]

Hi all,

I have a fairly technical question about connection multiple amp channels to a single output on a receiver. I am getting married in a couple of weeks, and want to connect six external amp channels to the Zone 2 output from a Yamaha receiver. If I build a custom RCA cable that splits the L/R output from the receiver into three parallel L/R leads, will that impact signal strength from the receiver output?

I have the receiver, and I have a Rotel 6-channel zone power amp, but need the same music playing on each of the 3 zones.

My second question is about wireless microphones. I have rented a wireless mic for speeches. Can I plug the 1/4" output from the wireless receiver into an RCA input in the same Yamaha receiver, or will there be signal strength issues here as well? I'm not sure if I need a small mixer in the middle.

Any help is appreciated,

Andrew (Groom to be)

You can use RCA splitters for your first question. Signal strength wont be a real issue.

A Mixer would be a good choice, instead of the receiver actually. You could hook up the source device and the mic to the mixer. The mic wont work well with the yammy... balanced vs unbalanced.

From the mixer, out to rotel, split how you need it.

The output level of a lot of "low-end" wireless units is unbalanced so unless you have a "tip-ring-sleeve" type phono jack on the wireless receiver it will be unbalanced should work with a 1/4 phono to RCA adapter into your receiver. You will not be able to mix the music under but will instead have to switch inputs on the receiver to select the input assigned to the mic.

If it is a Rotel multi-channel amplifier like the RMB-1066 then it has a single common input which can be linked to the other channels of amplification without the need for externally splitting the signal. Likewise, the input can be cascaded to other amplifiers if necessary.

Take a look at:

or

Find your amplifier and look at the back plane - let us know what you are using.

In the case of the RMB-1066 you connect your input to 'A' then you set amplifiers B and C to the 'LINK' mode with their switch. They will use input 'A' and play the same thing.

If you want a microphone on top of music you will need a mixer, if you just want a microphone, you may be able to pull it off with an unbalanced microphone, but I would still be looking for a really cheap mixer on eBay or at Radio Shack.

Hi all,
Thanks for the info. The Rotel amp I'm using is a RB-956ax. Unfortunately it's of a vintage where I can't "link" inputs together. The only toggle switches on the back are to switch pairs of channels from stereo to bridged mode.

In terms of the mic's, I have borrowed a 2-channel mixer from a friend anyway, so that is taken care of regardless of wireless receiver quality. I don't want to mix the mic over the music anyway, so those connections are pretty simple.

Sounds like you got it all figured out. Have fun, congrats. (dont do it )
