Panasonic WM-KG645 18-inch Gooseneck Microphone

Panasonic WM-KG645 18-inch Gooseneck Microphone is a straightforward podium/desk mic built around a unidirectional electret condenser element with a cardioid pattern. From the provided specs, it covers a wide 40 Hz to 20 kHz frequency response, terminates to a male XLR output, and is rated at 600 ohms output impedance (±30%). Sensitivity is listed as -40 dB (10 mV) referenced to 0 dB = 1V/Pa at 1 kHz, with a signal-to-noise ratio of 70 dB or more.

Highlights

• 18-inch gooseneck format for podiums, lecterns, and desk mounts
• Cardioid pattern with a unidirectional electret condenser element
• 40 Hz to 20 kHz frequency response for full-range speech capture
• Male XLR output for standard pro audio interfacing
• 70 dB or more signal-to-noise ratio for cleaner speech in typical rooms

Why It Helps

A gooseneck mic is all about consistency: stable placement, predictable pickup, and easy interfacing. WM-KG645 keeps the signal path simple with a standard male XLR output, a speech-friendly cardioid pattern, and published sensitivity and impedance values that help when you’re matching it to a mixer or DSP input.

System Characteristics

• Cardioid pickup helps focus on the talker and reduce off-axis room bleed compared with more open patterns
• The male XLR output is the practical win for pro installs and broadcast-style cabling
• With 600 ohms output impedance (±30%), it’s built around classic audio interfacing expectations
• The listed -40 dB (10 mV) sensitivity spec helps you set gain without chasing noise
• Environmental limits are clear: 5–35°C and 10–90% humidity (no condensation)
