Certification
Conforms to European Union directives, eligible to bear
CE marking; meets European Union EMC Immunity Re-
quirements (EN 50 082–1, 1992).
CONNECTIONS
These low-impedance microphones are designed for
connection to microphone inputs rated at 75 to 300 ohms.
Using balanced-line low-impedance cables permits very
long cable lengths without affecting response or level. The
GREEN and WHITE cable leads are the microphone con-
ductors for balanced-line connections; the shield is con-
nected to the amplifier ground.
For unbalanced operation, connect the WHITE lead to
the shield, and use the GREEN lead as the microphone
conductor.
The RED and BLACK cable leads are used to control
an external relay or control circuit.
Refer to the following tables and to the wiring diagram in
Figure 4.
