Small IEM Limiter?

Sorry for the old thread resurrect, but this is something that I am currently interested in. I'm looking for a simple, in-line limiter for my wired IEM system.

I have managed to locate the Invalid Link Removed. While it might be exactly what I am looking for, it just seems far too simple.

As I continued my research, I found an in-line Invalid Link Removed. The size and application are exactly what I am looking for, however these units appear to have been designed/manufactured in the '80s and may no longer be available.

For $200, the PreservEar system looks like it will do the job, but I am struggling with the price.

On the cheap/experimental side of the fence, there are the Griffin MyPhones and the Maxell SafeSounds which limit to 85db nad 95db, respectively. I'm guessing that they might just contain a simple passive circuit similar to the HeadWize and/or the BBC Limiters. I could potentially gut them for the suitable parts and make a little adapter.



Ideas? Thoughts?

Thanks!

I'm running my mic and bass DI thru the Rolls, as well as bringing in the house mix. The TastyBlender doesn't have instrument or Mic thru.

This unit still has possibility since I can have 3 inputs; I'd just need a splitter for the mic.

Thanks. :)

The only advantages the tasty blender has over the Rolls are the limiter (which I feel is really important when dealing with IEMs) and the ability to change the bass EQ.

Now if the Rolls had a limiter I would purchase it immediately
 
Maybe take a look at Posse Audio. Yeah it may seem a little cheesy but I'm kinda liking it. I get a feed from the board, add my bass and vocals and adjust to my liking. It has 2 condenser mics for ambience. I'm also using 1964 ears (quads)
 
Ive been looking iinto IEM and mixing and limiting myself, i came across rockon audio. they sell two things, the rockbox which is a headphone amp/limiter and the tasty blender which is mixer ,headphone amp and has 3 limiters in it (not sure what that means, just read it) that's the option im now looking at . built in limiter, more me function and 3 inputs.

take care

By the time you add any nearly-$200 limiter to a headphone amp IEM system, you're edging into the ballpark of a Shure PSM200.

Then there's the question of *where* to put the limiter with a Rolls 351. I believe you won't be able to brickwall both the TRS (line level) aux input and the player's mic input at the same time unless you are willing to lose some of the 351's functions or unless you invest in another piece of gear. Somebody correct me on this if you have a rig that limits the stereo in and the mic in at the same time w/o a 2nd limiter or a second (pre)amplifier stage.

If you're using both inputs and want a brickwall on each, I see three easy paths:

1. Buying two limiters—one for the mic input and one for the TRS monitor mix input.

2. Sending the mixed headphone output to the limiter (introducing potential problems with level and impedance mismatches) and then sending the limiter output to *another* headphone amp to feed your earpieces.

3. Putting another stereo mixer in front of the limiter, then sending the limiter's stereo output to the Rolls 351's TRS input, and feeding earpieces from the Rolls.

Anyone have a more elegant (and field-tested) solution w/ the 351?
 
I have both a Rolls PM351 and a Shure PSM200. The sound quality on the Rolls is far superior to the Shure, even though it does not have a limiter.

One option that I have experimemted with, but not extensively, is to route the output of the Rolls into the Shure receiver. The Shure units have limiters in both the transmitter and receiver, so this may be a perfect solution for some.
 
Yes. I mentioned the Shure not b/c it's awesome, but b/c it's IME the benchmark wireless unit in this price range. The wired Rolls + limiter sounds better and offers more features than any wireless I know of available for comparable $$.

OTOH, for ~$400, you're dealing w/ compromises.

Wow jovino - that sounds like a great idea. I think I remember someone else mentioning something like this in another thread. Keep the experiment going, and let us all know how it turns out.

This is where I'm at. I just converted to a wired IEM rig, but without limiters I'm afraid to use it.

I have a separate mixer to use, but its rather large (12 channel, seriously overkill), and doesn't have inboard dynamics processing. My problem, even if I patch a limiter in, what is the correct amount of limiting?

That's the cool thing about the PSM200, that the limiter does its thing without me having to risk getting a setting wrong and it doesn't properly do its job. With a built in limiter, there's way less room for human error, and further damage to my hearing.
 
I've used my Rolls w/ a Mackie DL1608, which provides a limiter for the aux outputs and lets me control my own IEM mix via wifi.

I've also used the Rolls a couple times with no limiter, but with my vocal mic and bass as the only inputs. My bass wasn't going to feedback or peak surprisingly, the level to my earpieces was fairly low, and my vocal mic was unlikely to feedback as there were no wedges nearby. Still, it's a risk—I could have been in trouble if some doofus (probably me) banged into my mic or knocked it over. And under no circumstances would I use IEMs w/o a limiter if the monitor feed were in the hands of a bandmate or a house engineer of dubious experience. That's why I've drawn the line at using it w/o limiter with the house board feeding the TRS line-level input.

BTW, RT, to dial in your limiter at the mixer, just follow the usual process for setting gain structure and limiting. ("System Limiting" on pages 9 & 10 of Invalid Link Removed will give you a typical walk-through.)
 
You may be surprised at how low the volume is on my IEM setup. I use it mostly to fill in the , missing frequencies that the earphones block out. It's somewhere around 1/4 vol or less.

I've use the wired Rolls without protection and have had a couple of feedback instances that worried me, but mic drops and yelling were okay. The Shure, on the otherhand, caught this stuff wonderfully.

If your risk is low and your volume is low, you might be safe-ish.
 
I used my iem setup for the first time this weekend. Our sound guy is good...so no overload or spikes.

I have the Carvin system....so I used the limiter in the wireless pack.

I still have a rack full of stuff...but at least no big cabinet to carry.

I have to figure out a signal chain still...and we had a bad hum coming thru at times. more practice with the system is needed..but we as a band are on our way to controlling stage volume.

I will post my signal chain when I figure out how to integrate the rollls pm351. I have the unit but didnt use it yet..
