4. Thread the gooseneck tightly onto the flange. Back the
hexnut up against the gooseneck. Use a wrench to tight-
en the nut firmly against the bottom of the gooseneck.
5. Slide the cable all the way through the gooseneck.
6. Thread the microphone firmly onto the gooseneck.
7. Connect the cable wires to the amplifier, mixer, or radio
transmitter via screw terminals, an XLR connector, or a
1/4-inch phone plug. See Figure 1 and Table 1 below for
wiring information.
8. Lock the microphone in place by tightening the setscrew
over the mounting threads. The setscrew in the name-
plate can be tightened to secure the grille.
NOTE: Use Shure A95 Line Matching Transformers to
match a low impedance (300 Ω) microphone line to a high
impedance amplifier or mixer input. The A95 is available with
various input/output connectors.
CONNECTOR WIRING
The 561 may be wired for either balanced or unbalanced
operation.
For balanced operation, the WHITE wire is connected to the
positive audio input, the BLACK wire is connected to the
negative audio input, and the SHIELD is connected to chas-
sis ground. Refer to Figure 1 and Table 1 below.
For unbalanced operation, the WHITE wire is connected to
the audio input, the BLACK wire is connected to audio
ground, and the SHIELD is connected to chassis ground.
