Title: Clear-Com FS II - 1.9ghz or 2.4ghz in North America
Post by: Andrew Broughton on April 23, 2024, 06:32:44 PM
For those of you that tour with FS II, have you had better luck with 1.9 or 2.4? I have the older 1.9ghz and have found it to be unusable in certain venues. CC recommends 1.9ghz in the USA, and I would think 2.4 would be pretty crowded, so hoping to get some real-world experience advice on what would be the best choice for a new system, being toured in the USA and Canada.
I wish they made a switchable transceiver and Beltpack!

I guess there's already a good thread on this, but it's from 2018. Any change in advice for 2024 +?

The local university's athletics department has an 8 pack of Hollyland's 1.9GHz units and, from second person reports, they have had good luck with them.  This is in a Midwestern city of ~150,000 people.  I can report from personal experience that 2.4GHz wireless microphones are nearly unusable here.  You have to almost co-locate the receiver with the transmitter to use 2.4GHz systems once the audience shows up.

Is the 2.4 better in domed arenas? 

With our 1.9 systems I've found that getting the transceivers higher up (like on the truss) does help quite a bit.

also there is a setting called audio filter, I think, that will help large arena dropout.

And use the latest firmware in the packs and transceivers. Also, PEPP® (Pete Erskine Pizza Pan) works; just put the transceivers as high up as possible. These tidbits are for the older E1 Freespeak II: The IP transceivers do not suffer nearly as much from multipath.

The PEPP® I use is an actual circular Pizza grate to shield the top of the E1 transciever from high RF reflections.

HERE IS THE SETTING IN ECLIPSE FOR LESS DROPOUT.  In the stand alone FSII there is a similar setting.

Are you referring to the "Audio RF Filter" setting?  The manual says that it "may help with audio dropouts" but is otherwise vague about what it does.
