Care to share your settings?
I tried running a frequency response test last night, and determined that
there is no way to measure it on the O2 since, even at low levels of input
it "hunts" for the signal and the output jumps up and down. This may
actually be a good thing for normal speech operating conditions, and this I
know from broadcasting that you absolutely cannot do a frequency response
test on a system without shutting down all devices in the chain that can
dynamically effect the level. TT may have designed some noise gate or level
"hold" function similar to what broadcast stations use which would make the
rig sound much better. But broadcast processors have a "proof" switch on
them that defeats all functions for testing, and that's not available on the
O2.
Next best thing is a pink-noise generator and an audio spectrum analyzer
hooked to a receiver with a known flat response. If I had a spare $25,000
laying around, I could do that :-)
