STEREO HEADPHONE USE
The SM10 microphone may be used as a boom
microphone with stereophonic headphones having pro-
visions for mounting boom microphones. These head-
phones are identified by a removable knurled knob or
screw on the left headphone cup.
To mount the SMlO on a stereo headphone, remove
the retaining clip from the SMlO headband arm by
removing two retaining clip screws (No. 3-48 x 3/16")
and hex nuts. Mount the retaining clip on the headphone adapter plate supplied using the retaining clip
screws and hex nuts. Unscrew the removable knob or
screw from the stereo headphone cup. Position the
headphone adapter plate with the retaining clip downward, and replace the knob or screw on the headphone
cup (see Figure 6). Snap the SMlO pivot housing into
the retaining clip, pivot adjustment knob upward, and
place the headphone-microphone assembly on the
user's head. Adjust the microphone position as de-
