Equivalent Output Noise

[1]

typical, A-Weighted

28 dB

Power Requirements

+5 V DC (nominal), 10 V maximum

(DC bias)

Polarity

Positive pressure on diaphragm

produces positive voltage on pin 3

with respect to pin 1

Cable

1.1 m (45 in.)

Connector

TA4F

Net Weight

60 g (2.11 oz.)

[1]

Measurements taken using

RK100PK preamp set @ 0 dB us-

ing 8k bias resistor.
*All specifications measured with a

48 Vdc phantom power supply. The

microphone operates at lower volt-

ages, but with slightly decreased

headroom and sensitivity.

Alimentation

+5 V c.c. (nominale), 10 V maxi-

mum (DC bias)

Polarité

Une pression acoustique positive

sur le diaphragme produit une ten-

sion positive sur la broche 3 par

rapport à la broche 1

Measurements taken using

RK100PK preamp set @ 0 dB us-

ing 8k bias resistor.
*Toutes les caractéristiques tech-

niques ont été mesurées avec

une source d'alimentation fantôme

de 48 V c.c. Le microphone

fonctionne à des tensions plus

basses mais au prix d'une plage

dynamique et d'une sensibilité

légèrement réduites.

Polaridad

Una presión positiva en el di-

afragma del micrófono produce

un voltaje positivo en la clavija

3 con respecto a la clavija 1

*Todas las especificaciones

medidas con fuente de alimen-

tación phantom de 48 VCC. El

micrófono funciona a voltajes

más bajos, pero con niveles

de limitación y de sensibilidad

reducidos.
