The IEM missing piece

This one goes in the category of why didn’t I think of this sooner?

Last time I wrote about the improvements to our IEM system that have come from implementing a new transmitter/receiver combo and some additional ear piece options.  The problem with adding more wireless into an already congested environment is a higher probability of failure.  I’ve personally managed to avoid Murphy’s Law when it comes to IEM for a long time but I realize it was only a matter of time before someone’s system failed during a service and we’d be in big trouble.

Enter Sidefills.  A friend spent a couple services with me post-Christmas and suggested that what we were missing was a good holistic stereo mix that will fill in the missing pieces when someone pulls an ear out and also provide some added energy to the first couple rows that might be a tad light from the PA over their heads.  It seemed like a good idea.

In my past life as a monitor engineer, sidefills were an important part of getting a great onstage sound since I worked with lots of vocal groups who would often times only wear 1 ear anyway.  For some reason, I never even considered it at KCC since our old PA already put energy everywhere except where I really wanted it – the prospect of adding an additional full-range sound source was unappealing.  However, in the new reality of a controlled PA without a ton of stage spill, it seemed possible this might just work.

Work it does.  I have a set of EAW KF300s that have been unused for a while.  I put them on top of the subs, about 5 feet off the ground, pointed in towards center stage.  Stereo mix gives more clarity & separation than mono, add some EQ to smooth out the rough edges of the boxes themselves, and add a few milliseconds of delay to the PA so the clusters in the air are in relative time alignment with the sidefills and the result is really good.  I’m feeding these boxes from FOH subgroups so they essentially get a rebalanced FOH post fader mix.  The mix is split up to rhythm, band, and vocals.  Using this approach keeps them specifically music-focused – playback and speech mics stay out of them.

We still keep a set of wedges on the front row for lead vocal monitors.  The addition of the sidefills allows the vocal to literally be surrounded by themselves – just a touch of vocal in those front wedges pulls the singer’s image forward.  Needing less band in those front wedges reduces mud heard at FOH since the sidefills are actually working with and as a part of the PA rather than against it.  I find myself putting 100% vocal in them, 80 or 90% band, and 60% rhythm (since the acoustic kit on stage adds its own ambient sound).

If you mix on a primarily IEM stage as I am and haven’t revisited sidefills in a while, this experience enthusiastically suggests they’re worth a try.

IEM Update

We’ve had a few updates & upgrades that have significantly benefited IEMs and figured this would be a good place to start getting back into this post the past few crazy months.  So here we go…

First, a few weeks before Christmas we were finally able to upgrade from wired IEMs driven from a headphone amp to Sennheiser EW300G3‘s.  The difference has been awesome in a few ways.  First, the sonic quality of the 300s is nothing short of amazing.  The low end is tight, the top end natural.  When paired up with a good set of ear pieces, I’ve been blown away by the mixes some of our guys are dialing in.  Second, not being tied to the IEM wired cable has made a big difference in the comfort level of our artists.  Often times we had to be very careful in how the service was programmed to make sure artists had ample time to get on stage, plug in their ears, put on guitars, tune, etc.  If something went wrong plugging in their ears or they accidentally pulled the cable out, we were in trouble.  Along with using more wireless instruments (I’ll write about this soon), the result has been a much smoother & more polished presentation.

We purchased 4 transmitters & 6 receiver beltpacks.  For the majority of things we do, we will use the 4 transmitters/beltpacks, along with our existing PSM600 and 2 wired mixes for keys & drums.  With some extra beltpacks for the 300s and our PSM600, we can easily expand by adding a few more mono mixes the few times a year they are needed.  It is so hard to justify extra transmitters in a rack if they aren’t going to be used very often so this seems like a reasonable compromise.

A big surprise is how much some of our female artists enjoy the bundled Sennheiser ear bud – the IE4.  The sound quality of the buds is probably on par with a Shure SCL3 or good set of iPod buds.  What is appealing about them, though, is how well they seem to fit smaller ears.  Our vocal director, who’s been wearing our generic Shure pieces for a year and a half or so, felt like these were the most comfortable thing and for the first time she can actually forget she’s wearing them.  Definitely a good problem solver.

Another important piece of the puzzle is the addition of some Westone UM2′s to our inventory.  After someone recommended trying them out, I’ve finally found something to make me give up my Future Sonics that I’ve had forever.  These are the most comfortable universal fit I’ve ever worn and they are the first universal bud that I’ve heard with really natural midrange, which is really important for vocals & guitars.  The Shures, Future Sonics, and Ultimate Ears I’ve heard all can sound really nice in the low and high ranges, but often times feel a little scooped, honky, or just otherwise unnatural in the midrange.  The Westones seem to bring a lot of that presence back.  Best of all, the Shure foamie’s I can purchase in bulk fit on these as well so its a win on all fronts.  Adding Westone’s into the mix have brought 2 of our hold-out musicians into the IEM fold.  Finally they feel like the guitar sound they hear in the ears feels like what it should actually sound like.

I’ve been really disappointed with the build quality of the Shure SCL3′s and 4′s so time will tell if the Westone’s can withstand heavy use.

So from a music team standpoint, we now have 100% of our band members transitioned to IEM.  Next time I’m going to outline another addition to our monitoring system that feels like its filled in the missing link in the chain.

Inside IEM Mixes: Lead Vocal

We finally made it to the last and likely most important mix in the IEM series…lead vocal/worship leader.  In this particular example our lead vocal is also playing acoustic, so not surprisingly you’ll hear those two inputs most focused in the mix.

As with some of the other mixes we’ve discussed, our vocalists seem to largely prefer their voices dry…if they want to wetten things up, adding more of the extras channel does the trick.  This works well in our particular setup since the vocals are fed to the IEM system direct off of board channels – adding verb would increase the complexity of routing.

I strongly encourage everyone who wears ears to keep both sides in all the time.  My primary reasoning is that your brain does a cool thing when it receives similar input from both ears in summing that source 6 dB internally.  So, if you only wear one ear, you’re going to have to turn up your IEM mix approximately 6 dB in order for it to feel as loud as both ears in.  Obviously you have to be really careful with this because an untrained artist could easily cause themselves hearing damage night after night of crazy levels in their IEM.

I say all that to say, the mix an artist wants changes pretty dramatically depending on whether they are wearing one or two ears.  These mixes you’re going to listen to today are one ear in mixes, so you’ll find that the acoustic, vocal, and click are WAY more out front then in the other mixes we’ve analyzed since the artist is getting a lot of their sound ambiently through their other ear not wearing the IEM.

Our philosophy at Kensington regarding ears has been to do everything possible to gain band acceptance.  By doing that, the stage volume lowers significantly and vocals have a much easier time just hearing themselves through a wedge.  I’ve mentioned that we have 6 channels of wired ears and 1 wireless transmitter/receiver system.  Because of this wireless limitation, we haven’t pushed very many vocalists to jump to ears.  This isn’t necessarily a bad thing since vocalists often have a much harder time adjusting to performing through IEM systems then instrumentalists because it can effect their pitch center, how loudly they perceive their head voice, etc.  So we’ve had good success getting musicians on ears and, by doing that, getting enough sonic space on stage for the vocalists to be able to hear themselves comfortably through wedges and not have to deal with their transition yet.

I’ve heard from another large church that they have the policy that a new vocalist must sing BGV on ears for at least 6 months in order to get used to them before they would ever ask them to sing lead VOX.  I can certainly see the wisdom in that approach.

We’ll wrap this whole thing up next time with the live mixes of the 2 songs we’ve been using for test material so you can hear overall context.  See you then!

Inside IEM Mixes: Keys

Continuing the IEM series, today we’re talking about the keys mix. We’re departing from the two tunes we’ve used for the rest of this series since there weren’t any keys in that band.

On a given week, we submix as many as three keys sources in mono to send to the IEMs. The first source is Ivory from our Slam Grand.  If the piano shell is not in the set, often times I will still run MIDI out of the primary keyboard into the Ivory system so that tone is available if we want a grand piano patch in the day.  The other two inputs are our house keys – a Yamaha Motif8 and a Korg Triton.  Every once in a while one of our artists might bring in their own boards but it doesn’t happen very often in a month.

I was concerned when we first installed our IEM system that the keys would need to be in stereo just like the drum kit in the ears mixes and that would present channel count issues with our desired allocation.  Thankfully, I don’t think anyone has ever commented on the keys being submixed to mono rather than stereo.  As a result, the only truly stereo submixes in the ears are the drum mix and the extras channels.  Everything else goes to the IEMs in mono and can be panned around in each individual mix as desired.

I’ve received a few questions via email for more information about the ambience mics specifically so I am preparing more info about that to tag onto the end of this series.

With that said, check this out…

Next time we’ll listen to the final IEM mix – lead vocal/worship leader.  Thanks for reading!

Inside IEM Mixes: Drums

Continuing our series on IEM mixes, today we’re going to focus on the drummer’s mix.  If you’ve missed the other parts of this series, go back through the last few days posts to catch up.  Sorry for the data dumps in some of these posts but I’m just trying to make sure I cover things as thoroughly as possible.

When we first adapted the PQ system for our IEM mixes, I was concerned that a stereo drum mix that everyone shared might cause problems.  The reality couldn’t be further from that.  A stereo aux creates the submix for the drums and it is slaved to the channel pan so whatever panning is done for the house translates to the ears.  I actually leave the sends to this aux set to unity in my default console setup.  That way, as I soundcheck the drums, I can build my house mix with the faders near unity and it translates almost perfectly to the ears.  It is RARE to need to tweak the mix for the ears – I actually can’t tell you the last time I listened to it other than preparing for these posts.  It just works every time.

By now you should be sensing some trends.  The ears mixes are pretty dry and really simple.  If we had a separate monitor desk, I’m sure there are more things we could do to make the environment even better for the artists (things like manually riding audience levels, riding solos, adding effects if desired, etc) but this system works for our guys, as evidenced by the wide acceptance factor.

Song #1 is still “My Savior, My God”.  Check it out…

Song #2 adds the click and track.  Again the click takes almost singular focus in the mix since everyone is locking to it.  I can’t speak very much into what it takes to be successful with the whole click track thing from an artist perspective.  Kensington has been using click’s for so long that it was just something we do by the time I got here.

Next time:  keys mixes.  We’ll have to use different songs then the ones we’ve been using so far since there wasn’t a keys player in this band.  It will be good to change it up a bit, as well!

Inside IEM Mixes: Bass

Today’s IEM mix we’re going to evaluate is from our bass guitar player. Again, there’s very little processing on the mix. This one would probably benefit from listening on better speakers then those on a laptop. The experience is pretty different for me listening to these clips on my speakers vs. on some good IEMs so you’ll probably find the same thing.

Right now is a good time to stress the importance of good ear pieces in order to achieve wide acceptance.  When I started at Kensington, all that we owned were some Shure E1s and NO ONE was excited to put those things on for anything.  The first time we did a band with ears for a holiday, everyone but the bass player wore E1s and it was painful.  Now we use Shure products exclusively (I’ve written about this before – check the archives if you’re interested in why) and have a mix of SCL3, SCL4, and SCL5′s.  Since I consider us still in the early days of a transition campus-wide to IEM, only a small handful of our artists own their own ear pieces.  Most use our house sets.  We stock the replacement foam and change it for each set whenever a new artist is using them.

Focusing now on the mix, our artists get a stereo drum mix to their PQ mixer for their IEMs. Everyone gets the same drum mix and we find that works fine for us. The only exception is that the bass player also gets the kick channel individually in addition to the stereo mix since bass players always want more kick then the rest of the band. When you listen to the first clip from “My Savior, My God”, the first thing that jumps out is the placement of kick and bass in relation to everything else in the mix. There’s also quite a bit more of the extras channels in this mix then in the electric mix we listened to last time. One caveat though – due to the channel limitations of our system on this particular night, the bass player chose to have mono extras rather than the normal stereo. Personally the stereo part of ambience is really important to me but this particular artist isn’t reliant on ambience so its a simple trade off. I’m actually surprised in listening to his mix that he has this much extras present. Regardless…

The second clip, like last time, adds a click and track into the mix. What is interesting is that with this mix, the click is pretty buried. In fact, once the drums kick in I don’t think it is very present at all. Again you can get a better idea of the importance of the extras channel in the mix when you hear the crowd singing along.
