The transformerless circuit design of the electronic impedance converter with symmetrical output
facilitates an output capability for sound pressures from15 dB(A) up to 136 dB with a maximum of
0,5 % THD (total harmonic distortion). The microphone is connected by a standard 3-pin XLR-male
plug with gold-plated pins which realizes the powering by an external 48 V phantom supply
according to IEC 61938 with a current consumption of 6 mA.
The M 221 consists of a microphone capsule and a microphone preamplifier as independent
mechanic parts which are connected to a complete microphone through a screw thread. Micro-
phone capsule and microphone preamplifier have an identical overall diameter of 12,7 mm which
enlarges to 21 mm over the length of the microphone preamplifier to the connection side of the
microphone. The shape of this enlargement is designed for a minimum interference with the sound
field. Microphone capsule and microphone preamplifier have together a length of 170,4 mm. On
the connection side of the M 221 there are standard microphone holders mountable. To reach a
higher attenuation against solid-born sound and impulses there are elastic holders and suspen-
sions usable. The weight of the M 221 is 123 g what allows to use the microphone with stand
mountings as well as to hang up the microphone from the ceiling without any problems.
