There’s more to those“toy” mics that it would appear. Since they are indeed “toy” mics, the receiver has built-in calibration to correct any deviations from flat frequency response they have. So for all intent and purposes, the system ends up being as accurate as if you had a expensive, high-end measurement mic.
It’s because of that built-in calibration that you can’t reasonably use any other mic: The receiver would add the calibration to any mic that’s plugged in. On top of that, the receivers don’t use a mic pre-amp that would be compatible with a standard calibration mic.
On top of that, measurement mics use balanced XLR inputs, while the receivers use an unbalanced 3.5mm input. So to use a standard mic, it would require a sound card with a professional-standard mic pre amp, whose output would feed to the receiver’s mic input with a pre-amp of unknown characteristics.
Getting the picture? It’s a lot of trouble for no benefit.
I’d say if it sounds better with the Dynamic EQ on, then use it.
Conversely, you could re-run the calibration, only this time keep the mic at the main listening position instead of various locations around the room. AudiocRaver has experimented with single-mic calibration and reports improved results. He’s written some articles on the topic that you can find at Home Theater Shack.
