Schoeps MK 4V
Small-diaphragm side-addressed cardioid condenser capsule (Colette series), on a CMC 6 amplifier
Power Phantom, 12 V or 48 V (CMC 6, automatic switchover).
- Type
- Condenser
- Pattern
- Cardioid
- Sensitivity
- −37.7 dBV/Pa computed
- Self-noise
- 14 dB(A)
- Among 258 condensers: quieter than 59%
- Among 272 mics: quieter than 60%
- Max SPL
- 132 dB SPL
- Among 277 condensers: takes louder sound than 26%
- Among 343 mics: takes louder sound than 24%
- Rated range
- 40 – 20k Hz
vs 99 side-address condensers
Quieter than 34% of 99 side-address condensers.
Each stripe is one side-address condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 107 side-address condensers
Takes louder sound than 32% of 107 side-address condensers.
Each stripe is one side-address condenser with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.
Proximity effect: the bass it gains up close
From the manual, p. 15.
Capsule on a CMC 6 amplifier ("+ CMC 6"), as printed; 0° is the side of the capsule marked by the red dot. Free field, distance and smoothing not stated; the sheet draws a tolerance band (dashed) around the curve.
Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.
Polar pattern
From the catalog, p. 8.
Rings every 5 dB, labelled 0 to -30 dB (the centre); 0° at the top. Left half 250 Hz to 2 kHz, right half 4 to 32 kHz; the pattern is taken as symmetric. Amplifier and measuring conditions not stated.

| Capsule | Small-diaphragm, side-addressed cardioid (Colette MK series)"0° axis is at the side of the capsule marked by a red dot" (p. 15). | p. 15 |
| Sensitivity | −37.7 dBV/Pa (13 mV/Pa)also −36.5 dBV/Pa, schoeps.de product page (2026), stated. Not stated by the manufacturer: From 13 mV/Pa: 20·log10(0.013). The product page states "-36,5 dB (V/Pa), 15 mV/Pa with CMC 6". | p. 20 |
| Self-noise | 14 dB(A)also 13 dB(A), schoeps.de product page (2026). Specifications for the complete microphone: capsule on a CMC 6 amplifier (p. 20). | |

| Output impedance | 35 ohmCMC 6 on 48 V phantom; also 25 ohm, on 12 V phantom | p. 7 |
| Rated load impedance | 600 ohmminimum recommended | |
| Rated frequency range | 40 Hz to 20 kHzalso [40, 19000], with CMC 6 / CMR, schoeps.de product page (2026); also [40, 38000], with CMC 6xt, schoeps.de product page (2026). Unlike the axial capsules, the MK 4V carries no footnote about extension beyond 40 kHz with the CMC 6 xt; the product page now gives 40 Hz - 38 kHz with the CMC 6xt. | p. 20 |
| Powering | phantom, 12 V or 48 V (CMC 6, automatic switchover) | p. 7 |
| Current draw | 4 mA48 V phantom; also 8 mA, 12 V phantom | |
| Connector | XLR-3 maleNot stated by the manufacturer: On the CMC amplifier; the guide shows the XLR output but does not list it as a spec. | p. 2 |
| Weight | 66 g"65 - 68 g, depending on type": the CMC amplifier; the capsule's weight is not stated. | p. 7 |
| Dimensions | 116 × 20 mmCMC amplifier: length 116 mm (incl. 3 mm capsule thread) × diameter 20 mm. The capsule adds to the length (not stated). | |
| Amplifier | CMC 6 (CMC 6U / 6Uxt); low-cut (-3 dB) at 20 Hz | |
| Maximum output voltage | 1 V (at 1 kHz into 1 kOhm) | |
| Polarity | Positive pressure on the 0° axis gives a positive voltage on pin 2 | |
| Character | Cardioid with mild high-frequency boost (around 10 kHz); highly consistent polar response; sounds somewhat brighter than the MK 4 | p. 15 |
| Use | All-purpose capsule for music and speech; spot mic in orchestra, double M/S; studio speech and vocals (pop filter PR 120 SV) | |
| Mounting note | On an RC Active Tube or GVC joint it will rarely end up aimed as intended when tightened; an O-ring (No. 800540, included) holds the capsule at any rotation | |

| Capsule size and weight | 34 mm long, 20 mm diameter, 18 g (capsule alone) | |
| Finish | Matte grey; Chromagreen or Smoked Silver (like the classic nickel) to order | |
