Hi, I am using Rh-910 MD for voice recording in seminar or interview. Unfortunately I am getting heavy hiss in all the recordings . my microphone is audio-Technica AT9830 ,Specification as follow; Model: AT 9830 Element: Condenser, electret Polar Pattern: Stereo, directional Frequency Response: 100 -12,000Hz Sensitivity: 58dB +/-3dB, 1 kHz at 1 Pa Impedance Ω: 680Ω Cable Length:1.0m, come with 3.5mm terminated Weight: 5gram with cable Phantom: tap power from DV-camera or MD player with mic-in power Recorder’s Setting: Record mode:Hi-SP Record level: Auto (AGC) Mic sensitive: High I hope to ger rid of hiss during recording,I have some doubts here; 1. Which one generate hiss, Recorder or Mic? 2. If problem came from Mic, is it any Mic(Mono or Stereo) is good for voice recording without hiss? (The mic must be small enough to mount on glass or shirt). 3. If I using Pre-amp mic with line in(Instead of Mic in), does it will eliminate the hiss during recording? Any suggestion ? Appreciate for your input. Thanks in advance.

Thanks for yours advice. Regards
