The NT5 is a pencil-type, small-diaphragm, mono condenser mic that was originally offered in matched pairs featuring sequential serial numbers so that they're close to each other all the way through manufacturing. A typical use of the NT5 would be as drum overheads or recording high-hats. We've found that they are detailed and very clear, and with just a tiny bit of compression they sound great. If you prefer the positioning flexibility afforded by a pair of small-diaphragm mics, then the NT5 is an easy choice. If you're lookng for a great-sounding, and very affordable single small-diaphragm condenser mic, the Rode NT5-S is a single NT5. Small-diaphragm condenser mics such as the NT5-S have an even and wider frequency response than large diaphragm condensers, handle higher SPLs, and can more accurately capture instruments with a pronounced high-frequency component (violins, for instance). Acoustic Principle: Externally polarised single diaphragm condenser transducer. Capsule Size: 0.5" (13mm). Active Electronics: JFET Impedance converter with bipolar output buffer. Directional Response: Cardioid. Frequency Response: 20Hz to 20kHz. Sensitivity: -38 dB re 1v/Pa +/- 2 dB equivalent to 12mV/Pa where 1 Pa = 94dBSPL. Equivalent Noise: 128 dB. Maximum SPL: 143 dB @ 1% THD into 1k_ Signal to Noise: 78dB. Requires phantom power, +38V to +52 V P24 Supply (20V-26V) The microphone operates in accordance with the above specifications to a minimum of 18V. (It will operate with some performance degradation below 18V.) Packed Weight: 1.8kg (Mic only 100g).
