Good morning everyone. I experienced an issue this weekend. We added 5 new shure psm 300 in ears for our singers. As soon as I turned on the first transmitter and musicians started playing. There it was a delay in the headphones. At first I thought maybe effects in the monitors. Muted effects and no results. I am running a SC 48 digidesign for front of house and a Yamaha M7CL for monitors in the back. I don't know if it is a setting on the yamaha or what. I was frustrated at the end of the day. Has anyone experienced this?

I agree with Shane. In-ears cannot cause a delay as you are describing. It's got to be elsewhere in the signal chain.

How much delay? A distinct echo? Comb filtering? Repeating echo? Have they used IEMs before?

How exactly is the rest of the system set up? How do you split? What kind of multi? How do you feed the IEM systems?

With more info comes better answers. Without info it is all just wild assed guesses.

It is hard to say. Maybe 3-5 ms. Comb filtering. Yes we have used in ears before. We use avioms connected straight from an interface card. We also have one sennheiser IEM unit. works perfect. Just need monitoring for singers and that is why those other units were bought. They are hooked up exactly like the sennheiser out of the omni outputs.

I am using a sc 48 venue for front of house and a m7cl yamaha for monitors. I might have something wrong in the routing or patching. I just spent about 3 hours messing with this issue last weekend. It should not be that complicated.

The M7 will have about 2.5ms, the PSM300 are 24 bit digital hybridso there is another 0.5ms of latency, and if you were using a digital mic suchas the ULXD there is another 2.9ms.

I have nothing useful to add to this thread but every time a see the title for a second my brain sees it as Latency in Years. Now that is a lot of latency. You may now continue with your regularly scheduled programming.
