Frequency response

Angle
Distance

Frequency response: from the response image. Captioned (on the product page) "Typical on and off-axis response of a 4066", with the note "Dotted line is with high boost grid and solid line with soft boost grid." Only an on-axis line per grid is drawn; distance not stated.

Dashed: outside the rated range, or simulated (other angles and distances). Hover or tap the graphs for values.

Polar pattern

Polar pattern: from the spec sheet, p. 3. Captioned "Typical directional characteristics of a 4066" (2024 print, p. 3); 5 dB per ring, centre -25 dB. Grid and measuring conditions not stated. Approximate reading error up to about 1 dB; some frequencies are identified by reasoning, not by the legend: 2k Hz.

Sensitivity−44 dBV/Pa (6 mV/Pa), nominal, ±3 dB at 1 kHz. "6 mV/Pa; -44 dB re. 1 V/Pa".
Self-noise26 dB(A), typ. (max. 28 dB(A))
Self-noise (CCIR 468)38 dB, ITU-R BS.468-4, typ. (max. 40 dB)
Max SPL136 dB SPL, THD < 1%, RMS (CORE+); also 139 dB SPL, THD < 1%, peak (CORE+); also 133 dB SPL, THD < 0.5%, RMS (CORE+); also 144 dB SPL, THD 10%, peak; also 134 dB SPL, THD < 1%, RMS (CORE, MicroDot); also 127 dB SPL, THD < 0.5%, RMS (CORE, MicroDot); also 120 dB SPL, THD < 1%, RMS (Legacy, before CORE; 2024 print). CORE+: "Distortion, THD < 0.5%: 133 dB SPL RMS, 136 dB SPL peak"; "THD < 1%: 136 dB SPL RMS, 139 dB SPL peak"; "Max. SPL, THD 10%: 144 dB SPL peak".

Dynamic range111 dB, typ.; also 97 dB, typ. (Legacy; 2024 print). "Dynamic range: Typ. 111 dB" (CORE and CORE+ tables). The 2024 print gives "Dynamic range - Legacy: Typ. 97 dB" (p. 2).
Output impedance35 ohm, rated, printed as "30 - 40 Ω". Not stated by the manufacturer: "Rated output impedance: 30 - 40 Ω"; the value is the middle of that range.
Rated frequency range20 Hz to 20 kHz. "Frequency response: 20 Hz - 20 kHz". Effective range ±2 dB: soft boost grid 40 Hz - 20 kHz with 3 dB soft boost at 8 - 20 kHz; high boost grid 40 Hz - 20 kHz with 10 dB boost at 12 kHz.
PoweringWireless systems: 5 to 10 V through a DPA adapter; with the XLR adapter: P48 (works from 12 V). "For wireless systems Min. 5 V - max. 10 V through DPA adapter. With DAD6001-BC: P48 (Phantom Power). Will work from 12 V".
Current draw1.5 mA, typ., microphone; also 3.5 mA, with the DAD9001-BC XLR adapter
ConnectorMicroLock, TA4F Mini-XLR, 3-pin LEMO or Mini-Jack (CORE+); MicroDot (CORE). CORE+: "MicroLock, TA4F Mini-XLR, 3-pin LEMO, Mini-Jack"; the CORE table says "MicroDot".
