62v8 Posted April 19, 2006 Report Share Posted April 19, 2006 A question for the smarter typesI'm looking at purchasing a Rode NT4 for live band recording with my MZ NHF800.Basic mic specs areAcoustic Principle: Stereo Microphone. 90Á XY placementActive Electronics: JFET Impedance converter with bipolar output bufferOutput Impedance: 200per sideSensitivity: -38 dB re 1v/Pa ± 2 dB equivalent to 12mV/Pa where 1 Pa = 94dBSPLEquivalent Noise: <16 dBSPL, (A-weighted per IEC268-15)Maximum Output: +13.9 dBu @ 1% THD into 1k ohmDynamic Range: >128 dBMaximum SPL: 143 dB @ 1% THD into 1k ohmSignal/Noise Ratio: 78dBHow does the comment in the manuals about minimum input level of 49 mV (is this RMS or peak) for line input come into play?Should this mic be put straight into "Line In"?By my book 49mV equals about 106dB on this mic.Intention is to run this mic off the internal 9V battery.Do I have to worry about anything at all or is this just some DC level and meaningless?Any assistance in explaining this would be greatly appreciated.CheersGT Quote Link to comment Share on other sites More sharing options...
A440 Posted April 19, 2006 Report Share Posted April 19, 2006 From this post, it looks like you should send the NT4 through Mic-In.http://forums.minidisc.org/index.php?s=&sh...indpost&p=92515 Quote Link to comment Share on other sites More sharing options...
ozpeter Posted April 19, 2006 Report Share Posted April 19, 2006 If you take the advice there not to use the supplied minijack cable and to make up you own, I'll repeat a suggestion I've made before (how can one repeat a suggestion that one has not made before?!) - buy a premade cable with minijack on one end to two phonos on the other end(s). Chop off the phonos and replace with XLRs. Soldering two cables into a little minijack is a real pain, but working with XLRs is pretty straightforward (and here at least you can get perfectly good solderless ones).

bisebaer Posted April 19, 2006 Report Share Posted April 19, 2006 I've been using the NT-4 for some time now and have always used it with the mic-in (power source: internal 9V battery). I did try the line-in, but the restults were rather disappointing, while the results with the mic-in are very good (in my opinion, at least).

62v8 Posted April 19, 2006 Author Report Share Posted April 19, 2006 GentsI didn't realise there were resistors in the 3.5 mini jack.Fair call ... I can reverse engineer a mini jack to 5 pin Cannon.But what was the 49mV thing about?GT Quote Link to comment Share on other sites More sharing options...
62v8 Posted April 19, 2006 Author Report Share Posted April 19, 2006 (edited) Blimey ... you are right ..Found the pad in the minijack cable.Side cutters will come out.GT Edited April 19, 2006 by 62v8 Quote Link to comment Share on other sites More sharing options...
