As a keyboard player who is also running the monitor and FOH mixes.  I'm looking for an easy way to turn the vocal effects OFF while the lead singer is speaking, and ON while he is singing.  Can I map this to a button on my keyboard or to a footswitch somehow?  I see that the MR18 has a midi IN and OUT but I am uncertain how to obtain the desired mapping.  

Hey! I have a Midas MR18 digital mixer (similar to the Behringer XR18) and want to connect from its (balanced XLR, mono) AUX outputs to the (unbalanced TRS, stereo) AUX inputs of a Behringer HA6000 headphone amplifier.

Depending on the number of participants (mix-minus feeds for each), I would like to support the following two scenarios:

1. stereo (L/R) headphone monitoring up to 4 people (Midas MR18 limit)
2. mono (R+R) headphone monitoring up to 6 people (Behringer HA6000 limit)

To be sure not to damage anything, I'd rather not start experimenting with different cables. Therefore, I have two questions (and a follow-up question, depending on the answer of the 2nd question):

Question 1: Would a 2x XLR female to TRS male cable (wired as illustrated below) work for stereo (L/R) headphone monitoring (scenario 1), connecting (paired) MR18 AUX outputs to single AUX inputs of the HA6000?

This would accomodate 3 headphones (AUX outputs only), or even 4 headphones (if I use the MR18 Main L/R outputs as well), to enjoy stereo monitoring.

Question 2: Would the same cable also work for mono (R+R) headphone monitoring (scenario 2), when simply not connecting one of the XLR ends and pressing the "MONO R" button on the HA6000, or is leaving the ring (or tip) signal of the TRS cable "floating" like this a really bad idea?

This would accomodate 6 headphones to be able to monitor in mono (mirrored).

Question 2b: In case using the same cable for scenario 2 is not recommended (see above, question 2), would an XLR female to TS male cable be advised?

Thanks a lot for any help with this! I've been searching the internet for hours already, but could not find any definitive answers to these questions. It seems not a straightforward thing, wanting to connect the MR18 to a HA6000, or similar device with unbalanced stereo inputs.

Note: I currently also own the Behringer AMP800 (which has balanced inputs and allows the use of regular XLR to TRS cables) but I want more connectivity options. Unfortunately, it seems headphone amps with more balanced inputs are not that common.

I have a Pro 2/DL231 issue.

The system setup is: FoH Pro2 and a monitor Pro 2. The FoH P2 is connected to the AES50 A X port and the Monitor board is connected via the AES50 B X port.

The Problem: I just did a firmware update on the entire system and it all updated without a problem. However, the monitor board is having issues with the DLs. Please see the attached picture.  It is still passing audio even with this issue but the red status light is keeping me up at night knowing this system has to be used in two days...  

Maybe the firmware changed some DL Settings? 

Thanks!
