We have a SX20 and we needed to hook it up to 4 external ceiling mounted microphones (Audio Technica ES945) We have connected them to a Audio Technica AT-MX351A 4 channel mixer and on to the codec through a standar balanced XLR to 4ring 3.5mm jack and it is working, but...... It will only work if we have the standard desktop microphone which come with the system attached. Anyone know how to get the system to work without this mic plugged in. We thought the 4 ring Jack would give us mic control too.
I have actually had success, this evening following a circuit posted online containing 2 caps 1uf each and 2 resistors 680 ohm. I actually had deflection of the software meter on the SX20, and did not have to apply external phantom power.
