Frequently Asked Questions - MX418DC SHURE

USER MANUAL MX418DC SHURE

Shure Microflex® MX400D Series microphones are miniature electret condenser gooseneck microphones with a desktop base and a 3 m (10 ft.) cable. Desktop base allows microphones to be used in multi-purpose rooms where quick setup is required, or where permanent installation is impractical.

Features

• Wide dynamic range and frequency response for accurate sound reproduction
• Interchangeable cartridges that provide a choice of polar pattern for each application
• Programmable mute button and LED indicator
• Logic input and output terminals for remote control or use with automatic microphone mixers
• Balanced, transformerless output for increased immunity to noise over long cable runs
  RF filtering

MX400 Series Model Variations

MX400 microphones are available with 305 mm (12 in.) or 457 mm (18 in.) goosenecks.

" S " models include a mute button and LED.
- "D" models include a desktop base with programmable mute button and LED and logic input and output.
- "SE" models feature a surface mount flange with side-exit cable.

The polar pattern of the included cartridge is indicated by a model number suffix:

C Cardioid
/S Supercardioid

/N Cartridge not included

Interchangeable Cartridges

Microflex microphones use interchangeable cartridges that allow you to choose the polar pattern for different installations.

R183 Omnidirectional

R184 Supercardioid
R185 Cardioid

Snap-Fit Windscreen

• Snap into the groove below the cartridge.
  To remove, spread the gap with a screwdriver or thumbnail.
• Provides 30 dB of "pop" protection.

Microphone Placement

• Aim the microphone toward the desired source, such as the talker.
• Aim it away from any unwanted source, such as a loudspeaker.
• Place the microphone within 15 to 30cm (6 to 12 in.) of the desired sound source.
  Always use the supplied windscreen or optional metal windscreen to control breath noise.
  If four or more microphones will be open at the same time, use of an automatic mixer, such as the Shure SCM810 or SCM410, is recommended.

DIP Switches

Use the DIP switches to configure logic settings and mute button behavior.

The DIP switches are covered with a piece of clear tape at the factory. Remove tape to modify the switch settings.

	OFF (factory default)	ON
1 M	Momentary Toggle
2 P	Push-to-mute Push-to-talk
3 M	ute button enabled, LED illuminates when mic is active	Disable mute button (microphone always on), logic controls LED
4 -- --

Wiring Diagram

NOTE: Audio and logic ground are connected at microphone base.

Mute Button Configuration

Use DIP switches 1 and 2 to configure the mute button, as follows.

Be sure to set DIP switch 3 off (factory default) so that the mute button controls audio from the microphone.

Switch Function DIP Switch Setting
Momentary: push-to-mute(as shipped).	ON1 2 3 4
Momentary: push-to-talk	ON1 2 3 4
Toggle: (Push On/PushOff): Mic is active whenpowered on	ON1 2 3 4
Toggle: (Push On/PushOff): Mic is mute whenpowered on	ON1 2 3 4

Connecting to an Automatic Mixer

Use these settings if connecting the microphone to an automatic mixer or other device that mutes audio and controls the LED.

1. Connect logic leads to the automatic mixer. Connect the LED IN to the gate output to illuminate the LED when that channel is gated on.
2. Set DIP switch 3 on. This disables the mute button (the microphone passes audio regardless of whether the button is pressed or not).
3. Set DIP switch 1 to configure how the mute button sends SWITCH OUT logic:

Momentary:
push = 0 Vdc,
release = 5 Vdc

Toggle:
initial = 5 Vdc,
push = 0 Vdc

Logic Wiring

Green (LOGIC GROUND): Connects to the logic ground of an automatic mixer, switcher, or other equipment.

Orange (LED IN): Set DIP switch 3 on to use LED IN. When shorted to LOGIC GROUND, the LED turns on.

White (SWITCH OUT): Provides TTL logic (0 Vdc or 5 Vdc) in response to the mute button. Set DIP switch 1 for momentary or toggle. When phantom power is applied, logic initializes high (5 Vdc). DIP switch 2 has no effect on SWITCH OUT.

Changing SWITCH OUT to Always Momentary

Use the following modification in situations where your logic interface requires momentary closure of the SWITCH OUT, but you want the mute button to toggle the microphone (DIP switch 1 ON, 3 OFF):

1. Access the circuit board inside the microphone base.
2. Remove the resistor at R45 and reinstall it at location R46.
