MD 46 – Dynamic Cardioid Reporter’s Microphone
The development of the MD 46 goes back to a request from the US TV giant, NBC. In 2000, NBC was not looking for the usual omni-directional reporter’s microphone, but for a cardioid version designed to meet the requirements
of rough live work. Sennheiser hand built 150 units and supplied them to NBC for field-testing.

Meeting with a very positive response from NBC, other broadcasters also indicated their interest in a cardioid
dynamic reporter’s microphone. Now the MD 46 is in full production. It is an ideal choice for outside broadcasts
where a rugged microphone is a must:

Speech clarity was optimised by increasing the mic’s presence and decreasing the frequency response curve in the bass. Therefore, the MD 46 does not require a low-cut filter.
The MD 46 is extremely insensitive to handling noise.
A two-ply gauze sound inlet basket provides increased protection from wind and pop noise.

Features:

Pick-up pattern: cardioid
Frequency response: 40 – 18,000 Hz
Sensitivity: 2.0 mV/Pa ±2.5 dB at 1 kHz
Nominal impedance at 1 kHz: 350 ohms
Dimensions: length 250 mm, diameter 49 mm
Weight approx. 360 g

As the world's leading manufacturer of microphones, headphones and wireless transmission systems, the Sennheiser Group, based in
Wedemark near Hanover, Germany, registered a sales revenue of more than DM 380 million in the year 2000. The export share is
approx. 80%. Sennheiser has a total workforce of approx. 1,300 employees, 800 of them in Germany. Sennheiser is active worldwide
