The Fort Worth Opera festival loadin starts tomorrow. Dog Days is one of the operas in the festival but it’s being produced in a different venue. The Dog Days load in starts on Thursday.
Here is the input list that came with the show:
I have some of these mics and some will be substituted for arguably “better” mics. Some will be substituted with arguably “comparable” mics.
This afternoon I setup a mic test rig using a QSC KW122 self powered speaker. I used the speaker because it is relatively flat and being self powered, took about 1 minute to have pink noise coming out of it. I set up a mic stand at roughly 6′ away from the speaker. The speaker’s HF horn was located at roughly 6′ off the ground with no objects between the mic stand and the speaker.
Note that the KW122 has a 3 way switch on the back. The choices are “Ext Sub” (reduces low end), “Normal” (flat response), “Deep” (extends low end). After measuring those 3 settings with the first mic, I selected “Normal” for all subsequent measurements.
This trace shows what the switch does:

Then I proceeded to take some reference measurements using my matched pair of Earthworks TC30K omni mics. Then I measured with my newly acquired Audix TR40 pair (non matched). After that I went through the rest of my measurement mics including an Earthworks M30BX (self powered), TC25K omni and then moved on to the mics to be used in the production.
This includes:
AKG 535
AT 4033
Earthworks SR20 / SR69 (same thing but older model)
Earthworks FM500 (flex mic)
Oktava MC012 / MK012 (same thing but newer model)
Sennheiser E604
Shure SM57
Shure SM58 / SM58S (switchable)
Shure Beta 52A
The Oktava bodies can work with different capsules so I compared all (6) cardioid, (4) omni (2) hyper cardioid capsules.
All in all it took about 3 hours to go through the process of documenting the serial numbers of the mics, measure and save the data.
