cable clamps.
You can connect up to two monaural
microphones to the AUDIO IN CH1/CH2

(not supplied).
The following is the procedure for attaching an
electret condenser microphone such as the ECM-

On how to attach the CAC-12, refer to the operation
manual for the CAC-12.

type, supplied with the microphone)
around the microphone, while peeling
off the protective sheets on both sides
of the microphone spacer.
3 Place the microphone in the holder so
that “UP” is at the top.
4 Close the microphone holder.
5 Tighten the screw.

not interfere with the viewfinder and
tighten the ball joint lock lever.
When attaching the ECM-674/678, use the
microphone adaptor supplied with the CAC-
12 Microphone Holder.
