=== Out of Phase Condenser Microphones - Not Recommended ===

Hilmar-at-Bose talks about Wiring Two Condenser microphones with a Y cord<ref>[http://bose.infopop.cc/eve/forums/a/tpc/f/8566055944/m/2711064151?r=2721044351#2721044351 Hilmar-at-Bose talks about out of phase condenser microphones]</ref>

I would NOT recommend the out-of-phase Y adapter (or any kind of Y-adapter for that matter) with condenser mics. These mics have build in preamplifiers and connecting the outputs directly will present the mics with the wrong input impedance.

The Y-adapters are pretty rare, I don't think you can buy them on line. You can buy an ordinary 2-female/1-male XLR Y adapter like [http://www.audiopile.net/products/Mic_Instr_Cables/MP_Adaptor_Cbls/Two-fers/YFMM_and_YMFF/YFMM_and_YMFF_cutsheet.asp YMFF] type

and put an [http://www.audiopile.net/products/Adaptors_Connectors/Adaptors/XLR_Barrel/adpt_xlrbarrel_CA-301/CA-301_cutsheet.asp XLR] phase inverter on one of the female ends.

Again, I would only recommend the adapter for dynamic microphones (like for example a Shure SM57). If you want to use KSM109s (which are nice microphones), you may have to use a little mini-mixer to combine the microphone signals. You can still use the XLR phase inverter on one channel to get the cancellation effect. The 109s should work for bear field as well as for overhead. For near-field you might have to engage the -15 dB pad on the mics.
