Electro-Voice N/D468
Dynamic (N/DYM neodymium), supercardioid, instrument mic with pivoting yoke
Power None: a dynamic mic needs no power. Low output: it needs a lot of preamp gain.
- Type

vs 272 mics
Quieter than 60% of 272 mics.
Each stripe is one mic with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
Proximity effect: the bass it gains up close
From the spec sheet, p. 3.
"Figure 1—Frequency Response", relative dB. Distance for the average response not stated (the sheet rates a "far response" of 60-22,000 Hz and says bass is minimal beyond 24 inches); room and smoothing not stated. EV calls it "Average Response" and says each mic's own plot may differ from it. The dotted "Close Response" shows the proximity bass rise; its distance is not printed (the text says maximum bass is "1/4 inch from the sound source").
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
Polar pattern
From the spec sheet, p. 3.
"Figure 2—Polar Response", "5 dB per division"; two circles, 500 Hz (left) and 5 kHz and 10 kHz (right), 0° up. Measuring conditions not stated.

| Output impedance | 150 ohmbalanced (low-Z); also 350 ohm, 2003 Telex sheet. "150 ohms balanced (low–Z)". The 2003 sheet says "350 ohms balanced (low-z)". | |
| Rated frequency range | 30 Hz to 22 kHzclose response; also [60, 22000], far response. "Frequency Response, Close Response: 30-22,000 Hz; Far Response: 60-22,000 Hz". No tolerance stated. | |

| Finish | Non-reflecting black; Memraflex grille screen"Finish: Nonreflecting black"; "Grill Screen: Memraflex™". | |
| Supplied accessories | 311 stand clamp; soft zippered gig bagThe 2003 sheet calls the clamp "311 Stand Adapter". | |
| Power level | -51 dB at 1 kHz (0 dB = 1 mW/pascal) | |
| Polarity | Positive pressure on the diaphragm gives positive voltage on pin 2 with respect to pin 3 | |
