Customer Question

I've got a microphone, plugged into phantom power and plugged into a loudspeaker with the 3.5mm aux input, would like to use it to give a speech to a group but getting little to no sound from the speaker. I thought that once the mic was powered I would get a line level signal from the mic. The loudspeaker works fine with an iPod, etc plugged into that 3.5 mm input. What am I missing? Do I need a pre amp for the microphone to get any reasonable signal strength?

To my understanding, a GLS ES-58 is a cardioid mic and does not need a phantom power supply to work. A Phantom Power Supply would be needed with condenser type microphones.

What is needed then is a mic pre-amp to boost the ES-58's low level to line level.
