Dave. Sounds like you are saying that IEM delay is relevant only for vocalists. What about the drummer that has in ears? When he hits the snare, for example, does the polarity make a difference for him/her?

@6imzadi The 2ms or so delay caused by a digital console affecting in_ears causes phase cancellation and tonal issues that are audible. That same 2ms delay timing issues for drummers with IEM's is not really an issue as it is less than 3 or 4 ms delay it would take sound to reach the drummer from a drumfill 4 feet away. I have yet to prove and recreate any relevant audibility issues with IEM polarity for drummers. For singers, it is easily heard.

HAHAHA....I finally looked at your bio,Dave. Surfing@Radar Towers,the Strand,and Hollywood BTS ? I love it. Your entire YT series is just over-the-top for the wealth of practical info. you've delivered. ASCAP's been running articles on semi/pro sound from the various engineers in the business,but their efforts don't even come close to what you're doing here. Thanks.Btw,do you mind if I sub your channel?

@sneakerset Thank you! and sub away.

@sneakerset Oh, and give me shout and lets meet up for a surf session!

Oh, and while 16k sounds are ear tearing even at low volumes, is it harmful? :)

[50ndr33]

Hi! If you stand in the middle of a "deadSpot" with the volume so high that it harms you ears, but you can't hear it because of the "deadSpot" - will it harm your ears? The same, is it dangerous to "listen" to 200 dB 15 hertz or 21 000 hertz?

Thank you very much! :)

Good tip... but I usually set monitors in front of stage or at the rear of the mics... so the speakers won be shoting at the mics... but yes there are times when we dont have the space or harware... so ill keep this tip on mind

keep it rocking bro... great vid...

Thats very cool, I never get to see stuff like this in back woods Alaska

@DR Hey,you're on !! I suspect you occasionally have to shoot down to L.A. via PCH for biz (mid-week), and you pack a board(in case glass-off looks good) My life is simple(and struggle-free) these days(Kiddy Bowl and the Pit). Other options: Beacon's(Leucadia)or the north side of Cardiff reef. Malibu is booked solid for weekend events....but Wednesdays are super-laid back(swell permitting),and permission to get into the rotation isn't a problem. Have you ever attended "Call to the Wall"?

@proaudioguy Propagation delay is interesting. Some pay way too much attention to it, and others not enough. I've always wanted to take a signal generator, an oscilloscope, and scope the signal delay of some various systems (digital and analog). Quick little test that could answer some questions.
