I have two microphone-related announcements:
- I’m proud to announce that Cross-Spectrum Labs is a sponsor for the upcoming InDIYana DIY audio gathering in Auburn, IN. As part of the sponsorship, we will be providing a calibrated Behringer ECM8000 and a free microphone calibration as door prizes. More information on InDIYana can be found here.
- Speaking of calibrated ECM8000s, I am offering a limited-time special on microphones - I’m selling Behringer ECM8000s with “basic” calibrations (on-axis frequency response only, no polar or off-axis data) for $75 plus shipping. The only catch is that the mics won’t ship before March 26. Again this is a limited-time offer. A month from now when I’m only selling the normal $100/unit products, if you ask if you can get the $75 deal, the answer will be “no.” Act now or forever hold your peace.
