BEWARE!
Shure GLX -D+ Dual Band Latency varies slightly depending on the Frequency Band and Group:
Z3, Z4, Z5 (2.4 & 5.8GHz Bands):
Group 1: 4.53ms
Group 2: 8ms
Group 3: 4.53ms
Z2 (2.4GHz band only):
Group 1: 4.53ms
Group 2: 8ms
Group 3: 4.53ms
Group 4: 8ms
@GMGM may I ask how you come up with 5-7 ms Latency on your FM9? Doesn't the FM9 have 2.(something)ms Latency?
I think an empty block is probably something like 2 ms. I measured by...
- guitar into a boss pedal with two outputs.
- output 1 straight into my DAW interface (UA Apollo)
- output 2 into a "true bypass" looper around the FM9, and into channel 2 of my Apollo (the looper was to make sure the Boss pedal wasn't affecting latency).
I recorded both tracks, and compared the waveforms (ie - counting samples or milliseconds). 5-7 ms is pretty consistent for most of my patches.
I don't think any of my presets are horrendous. Usually just one 'amp' and one 'cab' block. Almost all with additional reverb and/or delay. And more often than a not, with a drive block (sometimes two).
FWIW - I don't have much issue with 5-7ms, that's about my "pain" threshold for latency. Beyond that it really arts to bum me out.
So I did end up with the GLXD+, but only briefly. I returned it, and traded down to the Line6 G10S. It's not as "nice" as the Shure unit, but the latency is so much better. At this point, it's important to shave off every possible millisecond that I can.
I have not yet done the math on my current setup (latency from the wireless guitar transmitter, FM9 latency, the latency in the X32 mixer, latency from my in-ear transmitter). Any one of them individually or even two together is no big deal.
