Applications

M 70 PRO X
The M 70 PRO X dynamic microphone with extended and balanced frequency response has been designed for high-quality recording of speech, vocals and instruments. Unwanted sound waves are effectively suppressed by the pronounced cardioid characteristic, and the precisely tuned proximity effect guarantees consistent sound clarity. An extended frequency response provides a differentiated and high-resolution sound image.
The robust design of the M 70 PRO X ensures durability. The integrated elastic system suspension protects the microphone against structure-borne noise, and the pop filter supplied largely suppresses plosive sounds.

The M 70 PRO X is particularly suitable for the following sources:

Speech for broadcast applications (radio, podcast, streaming)
Vocals (rock, pop music)
Guitar and bass amps

M 90 PRO X
With its 34-mm true condenser capsule, the M 90 PRO X condenser microphone has been specially developed for high-quality recording of vocals and instruments but is also suitable for the natural-sounding recording of speech during broadcasts. While unwanted sound waves are suppressed effectively by the pronounced cardioid characteristic, the lownoise circuit specially developed by beyerdynamic ensures that the electrical signals are processed to the highest standard. The integrated elastic system suspension protects the microphone against structure-borne noise, and the pop filter supplied largely suppresses plosive sounds.

The M 90 PRO X is particularly suitable for the following sources:

Vocals
Acoustic guitar
Piano
Strings
Speech for broadcast applications
Universal use (percussion, room miking, choir and orchestra)

Installation and commissioning

Cable trip hazard
Carelessly laid cables pose a trip hazard. This can injure people and damage the microphone.

Always lay cables so that no one can trip over them.

Attaching the unit

Unscrew the mounting nut from the microphone thread.
Insert the microphone into the spider with the bottom side first.
Tighten the mounting nut on the thread.
Attach the microphone to the stand with the stand connector.
Attach the microphone to the stand with the stand connector.

Connecting the unit

The M 70 PRO X has a 3-pin XLR connector. It can be connected to any microphone input with a suitable microphone cable.
The M 90 PRO X has a 3-pin XLR connector. It can be connected to any microphone input with phantom power (24–52V) with a suitable microphone cable. You therefore need to activate the phantom power.

Aligning the device

Unstable stand
An unstable stand can fall and damage the microphone mounted on it.

Make sure that the stand used and the microphone mounted on it are stable.

Position the microphone so that the speech direction is opposite that of the source of interference to achieve the best possible noise suppression.
