I connected a microphone (600 Ohm impedance) to a Roland MC909 but unfortunately I couldn't record anything... The volume is very very low. I checked everything: the input type is set to Microphone, mono, the volume knob is ok, the microphone is working correctly on other devices. Do I need to use a pre amp (such as a mixer) between the MC909 and the microphone? Do you have the same problem? Regards, Mario Jannelli
Mario, If it's a high impedance mic input (usually a 1/4" jack), you'll need a low-to-high impedance matching transformer. They usually have an xlr input, and a 1/4" plug. The voltage from a low impedance mic is quite low, and high impedance mic inputs expect more. There are three-pin xlr to 1/4" adapters (direct connections internally -- not a transformer) that allow a low impedance mic to be connected to a high-impedance input, but you'd get low volume -- you need a transformer.
