I have just purchased a Sennheiser ME66 for use with my Canon XL1s. Rather than purchase the MA-100 or MA-200 XLR mic adapter I purchased 2x XLR to phono adapters to save money. However the recording level is extremely low using the ME66 compared with the sandard XL1s microphone. Does anyone know if the canon MA adapters have some sort of power boost or is there a way to get good results with the ME66 without spending $200 - $300 for a Canon adapter?
