Preparations
Microphone and Preamplifi er Connection
The proper selection of microphone and preamplifi er depends on various
factors, such as the level to be measured, frequency range, purpose of the
measurement, etc. (For details, see the section "Technical Reference" start-
ing on page 81.)
Connect the microphone/preamplifi er to the INPUT connector. For pre-
amplifi ers without cables and for extending existing cables, the condenser
microphone extension cable series EC-04 is available as an option.
Important
Preamplifi er power supply
Normally, the PREAMP power selector on the
rear panel should be set to ±12 V. If wishing to
set the selector to ±45 V, fi rst make sure that
the preamplifi er (microphone) is compatible
with this voltage.

Before using the microphone and before putting
it away, always check that the microphone grid
has not become loose. If this has happened,
refasten the microphone grid fi rmly and then
