2. Boom Work:

For this kind of work we have supplied an elastic shockmount,
which may be fastened to the boom by a 8/8" or 5/8" thread.
Please refer to the enclosed manual for theH 30, explaining
the use of this accessory. "

5. The Usage of the Matrix UM 52:


For correct left/right orientation, be sure to mount the
microphone in such a way that the symbols shown always

face up.

3. Applications on Microphone Stands:

To mount the microphone on floor or table stands, a stand
adapter is enclosed. The SA 41/ i may be pushed onto the
microphone following the routine shown on the related sketch
explaining the handling of this accessory.

For correct left/right orientation, be sure to mount the micro-
phone in such a way that the symbols shown always face up.

4. Outdoor Work:

The included foam-type windscreen may be easily pushed
onto the microphone head by slightly turning the microphone
at the same time. .The windscreen should be always used
outdoors to prevent noise or drop-outs generated by sudden
gusts of wind or microphone movements.
