MODEL 561
OMNIDIRECTIONAL DYNAMIC MICROPHONE
The Shure Model 561 is an omnidirectional, low-impedance
dynamic microphone designed for use on a stand or flexible
gooseneck. Its smooth frequency response is tailored for optimum
speech intelligibility, making it ideal for language labs, paging
applications, and base station communications. The 561 is also
suitable for use as a talk-back or cuing microphone in TV, film, and
recording studios.
FEATURES
Frequency response tailored for speech applications, with
bass rolloff and mid-range “presence” rise
Omnidirectional pickup pattern
Low impedance; long lengths of cable can be used without
affecting microphone response or level
Shock-mounted cartridge for reduced stand and handling
noise
Rugged die-cast aluminum construction
Lockable stainless steel mesh grille
Optional gooseneck and mounting flange
GOOSENECK MOUNTING AND INSTALLATION
1. If necessary, drill a hole approximately 7 mm (1/4 in.) in
diameter through the mounting surface.
2. Place the flange over the hole in the mounting surface and
secure it with three screws.
3. Thread the supplied hexnut all the way down on the flange.
4. Thread the gooseneck tightly onto the flange. Back the hexnut
up against the gooseneck. Use a wrench to tighten 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 nameplate can be
tightened to secure the grille.
NOTE: Use Shure A95 Line Matching Transformers to match
a low impedance (300 :) 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 chassis 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.
