The MKH 8040
The MKH 8040 is a high-end cardioid studio condenser
microphone from the modular MKH 8000 microphone series.
This series has the following features:y Exceptionally low inherent self-noise prevents masking offiligree sound structuresy Symmetrical transducer technology ensures extremely lowdistortiony Extremely wide frequency response for an optimum
resolution of the finest details
y Transformerless and fully floating balanced output provides
for easy connection at minimal distortiony High sensitivity ensures interference-free transmission witha high signal voltage
y Frequency independent directional characteristics forminimum colouration in the direct and diffuse fieldy Rugged metal housing with non-reflective Nextel coating,making the microphone the ideal choice for in-vision usey Compact design and small diameter allow the unobtrusive
positioning of the microphone, even close to instrumentsy Modular design provides for easy exchange of themicrophone heads and the use of specially-tailoredaccessories to suit every application

Putting the microphone into operation
Connecting the microphone
Connection data of the MKH 8020:
y 48 V (+/- 4 V) phantom powering (as per DIN 45596)
y XLR-3
y balanced
y 25 Ω impedance
y 1000 Ω min. terminating impedance왘 Use a microphone cable with XLR-3 connector to connect themicrophone to the sound recording device. The soundrecording device must provide 48 V phantom powering.
Attaching the microphone using the microphone clip
왘 Select the suitable mounting thread:– Without thread insert: 5/8" thread– Thread insert: 3/8" thread왘 Screw the microphone clip 쐏 to a floor or table stand.
왘 Place the microphone into the microphone clip.

Using the windshield왘 Slide on the wind shield 쐃 to minimize wind noise.
The wind shield changes the sound only slightly, butattenuates wind noise by approx. 30 dB.
