We want to record the speech in acoustically live environment:
1) Can we use a Condenser microphone (Audio Technica AT897) in small consumer grade low end DVR e.g. Sony ICD-UX200 or ICD-PX820 after patching cable from XLR jack to stereo mini jack without compromising on audio quality? (e.g. low speech intelligibility, hiss sound etc.)Or is there something missing in this chain e.g. preamp or impedance matching transformer etc…
2) If hiss is inevitable in my chain then is there any good software which can delete this unwanted hiss and ambient noise?
3) I will patch it like this:
ICD-UX200 Recorder Microphone jack input for plug in power has
level 0.9 mV, 3 kilohms or lower impedance microphone.
ICD-PX820 Recorder Microphone jack input for plug in power has
level 0.5 mV, 3 kilohms or lower impedance microphone.
The signal appears across Pins 2 and 3; Pin 1 is ground (shield). Output phase is Pin 2 hot positive acoustic pressure produces positive voltage at Pin 2. To avoid phase cancellation and poor sound, all mic cables must be wired consistently: Pin 1-to-Pin 1, etc.
Nominal open circuit output voltage shall be 10.0 mV (phantom) or 8.9 mV (battery) at 1 V, 1 Pascal. Output shall be low impedance balanced (200 ohms phantom, or 300 ohms battery).

The Juicedlink CX211 (an XLR preamp) that I know only takes unbalanced audiowith pins 1 & 3.
I’m not exactly sure how the standard XLR to 1/8″ adapters work, but if you can’t findan answer through Google, then I wouldjust buy an XLR to 1/8″ adapter. This will also convert the impedance, rather than just changing the connection plug type.
