PADDLE & AC2 for IEM's
« on: May 18, 2016, 03:44:16 pm »

OK everyone,

I got a AC2 combiner and I am going to order a cable.

I am thinking 25 ft of 50 ohm cable  ??

I have also ordered the Sennheiser Paddle (smaller one)

Also, I read some people use a signal booster ? 

http://www.amazon.com/Sennheiser-AB3-G-Booster-Wireless-Antenna/dp/B002FOEKMI

I have 4 boosters in back of our rack, should I use one of them in line ?  and if so, will the booster boost all signals A&B ??????  or do I need to put both an A&B inline to make that happen ?

The current IEM rack has two A's (500's)and two B's (600's) in it.


Welcome to FR world !

Hi Patrick,

The AB3 booster is designed for use between a receive antenna and a radio microphone receiver to compensate for cable loss, it is not suitable for use between the output of an IEM transmitter or combiner and transmit antenna.

The paddle should either be a 1031 for omni coverage, or more likely an A2003 for directional coverage. The other paddles by sennheiser such as AD3700 or A12 are all designed for RX not TX.

The only way to get more signal out of an AC2 is to put more input power in from your transmitter, minimise the loss in the cable feeding the antenna by using a low loss coax, and using a directional antenna.

Cheers,
Neil

...and, make sure your actually need more power before you go down that road. With RF, all you need is enough. More power usually just gets you more intermod and other problems. If your application is mostly small stages you should be fine with what you have. More info here:

This idea is something a lot of people don't understand.
More RF power is not going to necessarily make things better!
This is a "less is best" situation.

Also, since most in-ear receiver beltpacks do not have a diversity scheme, using a circular polarization antenna is quite useful.

Sennheiser produces the A5000 but you could also buy an antenna from another manufacturer:

PWS and RF Venue both produce aclaimed helical products.

I personally haven't tried the RF Venue, but judging from the reviews and user cases in the internet, has to perform just fine.
