choosing a wireless transmitter for IEM

Naive too! Buh bye!

Don't cry, I'm sure you can live with that.
Even if you talked to such a dangerous criminal like me.

Last weekend I got the chance to play on an IEM rig from a friend (sennheiser 3056U). Looks like a professional (but little outdated) IEM transmitter model.
I was a little surpirsed to find the same problem as i had on the cheap ass model I used before. The noise floor (sea shell hiss) is high (stereo mode, without limiter on - on the receiver) and increases when low frequencies are played thru the IEM. I think it has something to do with the system Sennheiser uses for the transmission (HiDyn stage).
I tried switching frequencies and settings as well. Mono is better (but I like the stereo option), and limiting on decreases the hiss, but also the dynamic sound of the IEM mix.
Gain staging is not the issue, the IEM transmitter was driven with the volume meters at 95%.
Is this is a well know issue for all IEMS?
Or do silent and almost hifi IEMS exist?

My Sennheiser IEM does make some noise. But not as much as you seem to describe. It's the kind of noise you hear only when there is no signal in the IEM.

Sennheiser IEM's have a noise floor.. my G3 did, but only when nothing was being sent to them.
Definitely NOT audible when playing.
Gain staging IS important with IEM's like any device, so one has to "play" with it to get the optimum levels.
The noise (on my G3) was minimized by lowering the receiver volume and increasing the signal level to the transmitter.
I seldom ran my receiver at anything above 1/4 volume. Plenty loud w/ my [low impedance] 64Audio A8 buds.
YMMV

I lurk a lot in this sub forum, and there are few that I tend to listen to because of the information they post, and their neutral opinions. I've learned a lot from this sub forum, and a lot my purchases were made because of their opinions. I've also spent a lot money on things that I should have went a different direction with based on their opinions... but I've learned from it. Just because I tend to value their opinion... doesn't mean it will work for me. But it did help me go in a direction with my wireless gear, and very happy with what I use today. It will never an end all be all setup... I'm sure it will change again in the future.

I went from a digital wireless IEM system (Mipro M-58) to an Analog (Senn EW IEM G4) from points made from people that I value their opinions. As far as the hiss on my Senn G4... I don't notice it. I barely notice it when I turn it on (Actually, the hiss tells me I turned my belt-pack on... LOL)... but when we start playing, the hiss isn't audible... and I don't really notice it anymore between songs.

I know some make a big deal on latency with all the digital gear we use today. The places I play at all have digital mixers (~.8ms), I have an HX Stomp (~1.8ms), I went with a digital Senn EW-D Cl1 wireless for my bass (1.9ms). If there is one thing that I want to cut down on latency, it would be my IEM's... which is was the main reason I went with the Senn EW IEM G4 analog system. If I'm at around 5ms... or under 7ms... I'm happy with it... even if there is a very minor hiss that I don't even notice. Thank you for all those that helps in this forum... I really love the choices I've made on wireless gear... and IEM's.

Shure PSM-300 or Spend up on the G4 ?

If the Shure is workable, their stock bubs, the CL step ups or just use KZ10's?


Well I went with the PSM 300. Only ones in stock had the optional CL upgrade buds. I'll probbly sell those..

I've never used the stock buds on the Carvin, Shure, Senn or Mipro units I have owned.
Nothing wrong with the PSM300 - it was on the short list (along with Mipro 909, PSM600 and G4) when looking to upgrade my G3.
When I sold the G3, the buds went in their "still sealed" unopened package.

I went with the Mipro. Still using my 64Audio A8's !!

I used the PSM 300 yesterday at rehearsal. Using Etymotic buds. Custom molds next I imagine. Very nice sounding setup. Going to do a comparison of the Etymotics and KZ 10 Pro this week while reviewing material for a 3/9 gig. May the better bud win

@s0c9 After reviewing the areas I play with the Shure Frequency Finder in your link, G20 band was the obviois choice. That was real helpful!

Happy to see it was of use to you Mal..

Makes a huge difference when local TV stations aren't stepping all over your wireless signal!!

Hi, it's almost 2 years later, but have you made a choice on what IEM vendor to use?
