Shure 561 User Manual

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

Model 561 Dynamic Microphone

User Guide

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.

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.
