Upcoming Tour Wireless Setup

(1/1)

Russel Murton:
So, I'm going on a nice small east coast tour here in Australia with two industrial metal bands, I'm doing FOH, backline, monitors etc Dedicated LD, between us we'll take care of the production for the tour, in conjunction with the inhouse production at the venues we go to. We are going to touring a full lighting rig as well as backline, console, mic package, leads, stands and possibly some foldback depending on the venues production. Maybe even some subs for one venue.

We're having a production day on Sunday to rehearse as well as sort out audio and lighting setups and design.

My main concern is the wireless setup.

We will be using the following:

2x Sennheiser EW500 G3 /w e945's
1x Shure (Not shure if ULX or the other) /w Beta 58 capsule
1x AKG (Not sure which model) /w D5 mic
3x Ashton In-ear setups (Weak link in terms of quality)

I have an active 4 way splitter, Sennheiser, and two passive directional antennae.

My main question is if the AKG and Shure can also be fed by the Sennheiser 4 way splitter or are there problems with the BNC standard etc used?

Ideally I'd hook up the 4 wireless mic receivers to the splitter to the two antennae, place the antennae either side of the stage and then run the ashton IEM's off their own antennae at least ten feet from the Sennheiser antennae.

One e945 will act as a backup during the first band with the D5 doing main vocal, then during the second band we'll have the Beta 58 doing main vocal with a e945 doing backing vocals and a e945 as backup. I'd run a Rode M1 wired backup. New 9v batteries each gig.

I'll run the Sennheiser program via ethernet and do a scan for free frequencies for an hour before each gig and group the wireless mics on the same bank and the Ashtons on another on free channels.

Is there anything I'm clearly missing? I assume it is not wise to mix receivers and transmitters on the same antennae, plus I think the Sennheiser is only a receiver splitter and that they have another model for IEM transmitters.

Yes, each of those wireless systems will have a 50 ohm BNC connection. What you have to check is to see if the Sennheiser splitter covers the frequency bands of all the various wireless systems. Make a list of the wireless units and their frequency ranges. The Sennheiser splitter will also show a range. As long as everything is covered, it should work.

Overall, a good plan. Usually though, a pair of diversity antenas (the two Senny passive LPDAs) are probably best run from one side of the stage - nearest to your receivers. That way, you have shorter cable runs. You'll want to place them a few feet apart (on either side of the monitor console for instance) and at least 10 ft away from the IEM transmitter antenna.

new batteries for each gig is a good policy.

Just be careful about adding wireless channels on "clean" frequencies without taking into account intermods. One way to check for this is to have all your RF mics on, and turn off one at a time. You should see the RF on that channel at the receiver drop to zero or very low. If not, you may have an intermod there.

I think you have a fairly good handle on it.
