Frequently Asked Questions - MD 300 Microtech Gefell

What type of microphone is the MD 300?

The MD 300 is a dynamic microphone using a moving-coil principle with a cardioid polar pattern.

What is the frequency response of the MD 300?

The frequency response ranges from 50 Hz to 16 kHz, with a subtle presence boost of approximately 2 dB between 2 kHz and 8 kHz to enhance speech clarity.

Does the MD 300 exhibit proximity effect?

Yes, but it is well-balanced to avoid excessive low-frequency emphasis at close distances, making it suitable for close-talking applications.

Can I use long cables with the MD 300?

Yes, thanks to its balanced low-impedance output (220 Ω), the MD 300 can drive long cable runs with negligible signal degradation.

What accessories are included in the box?

The standard delivery includes the MD 300 microphone and a microphone holder MH80, all in a carton box.

Are shock mounts available for the MD 300?

Yes, optional elastic suspensions EA30 and EA92 are available to reduce handling noise and vibrations.

What is the weight of the MD 300?

The microphone weighs 330 g (without accessories), making it comfortable for handheld use over extended periods.

What polar pattern does the MD 300 use?

It uses a cardioid polar pattern, which rejects sound from the rear and sides, ideal for focused pickup in live and studio settings.

Can I mount the MD 300 on a stand?

Yes, the microphone has an internal thread at the base for attaching standard microphone holders or stands, either elastic or rigid.

What output connector does the MD 300 use?

It uses a standard 3-pin XLR male connector, wired according to DIN 60268-4 for balanced audio.

Acousticalspecifications

Adynamiccapsulewithacardioidpolarpatternisinserted intheMD300assoundtransducer. The frequency response has been optimized for low recording distances with an accentuation of approximately 2dB between 2kHz and 8kHz to raisethespeech and high-frequency presence. The change of the low end frequency response caused by the proximity effect is well-balanced without a very strong overemphasis at small microphonedistances.
