TuneStudio Mixer and ATR25 Condenser Microphone
I recently purchased a Belkin TuneStudio Mixer/iPod Recorder to record my children's music performances and to record sound for video. I have a cheap AudioTechnica ATR25 condenser microphone which worked well for me when I used it with my Canon HV20 camcorder. However, I did not have much luck with my attempt to use this microphone to record sound directly to a cassette recorder (analog), the signal was always too weak. Now, I tried the same microphone to test my newly arrived TuneStudio Mixer and still not getting any good results. The mixer can accept balanced or unbalanced signal via XLR or 1/4 inputs. I connected the ATR25 via 1/4 input and the signal is very weak. If I increase the input volume and gain control to the max, then I can hear the sound from the microphone but this time the background humming is extremely high. Actually, I should say that I can hear the loud humming noise in the foreground and the weak microphone signal I intend to record in the background.
The output impedance of ATR25 is 600 ohms, whereas the input impedance of the mixer is over 20,000 ohms. Could this be the reason why I have a weak signal? I would appreciate your help. |

Steve, thank you for your reply. I borrowed a Shure Dynamic microphone with XLR connection and tested the TuneStudio which worked well. So, I decided to buy a microphone with XLR connection. I will keep the ATR25 on my camcorder. I am planning to buy Shure SM57 (~$100). I read that it is good for recording musical instruments and for general sound recording including vocals. Do you have any other suggestion? Thanks for your help.
