CIRCUIT DIAGRAM
APPEARANCE
The microphone is supplied with a 5-pin DIN style connector pre-fitted.
This allows direct connection to the AVS AVU2001 or AVU2002 pre-
amplifier/line-driver units.
If required, this plug may be removed, and a different connector fitted.
Most preamplifiers or mixer amplifiers typically require a 3-pin, XLR
type plug, or a 3-pole 6.3mm (1/4”) jack plug.
The wiring for these types of connector is shown below.

internal terminals frequently differ from one manufacturer to another, you should use an ohm-meter to
establish which terminal of the plug is connected to which element (Tip, Ring and Sleeve).
