Features
This wireless micro hone system is designed to be
used with a video camera recorder, etc. By attaching
the receiver unit onto a video camera recorder, etc.
you can receive the sound icked u by the
transmitter unit. You can enjoy vivid sound which
matches the zoomed u images recorded by your
video camera recorder.
You can also use this system with a ta e recorder as a
conventional wireless micro hone system to record
the sound.
• The o erational distance between the transmitter
unit and the receiver unit can be u to
a roximately 45 m (150 feet). However, this
distance may become shorter if there are some
obstacles in between the transmitter unit and the
receiver unit.
• The radio frequency can be selected so that a less
busy channel can be used while the air is busy.
• Com act design featuring built-in antennas.
• The transmitter unit is equi ed with a lug in
ower∗ ty e MIC jack (monaural/ 3.5 mm dia.) An
o tional micro hone other than the su lied one can
be connected to this jack.
• The transmitter and receiver units are equi ed with
cli ty e holders with the adjustable cli s which can
be rotated 360 degrees so that the transmitter and
receiver units can be attached onto your clothes, etc.
• The receiver unit is equi ed with the MIX MIC jack
to which an o tional micro hone such as the
ECM-T145 (lavalier micro hone) can be connected,
so that the sound transmitted from the transmitter
unit can be mixed with the sound icked u by the
o tional micro hone.
• The receiver unit is equi ed with the v (ear hone)
jack to which the su lied ear hone can be
connected, so that you can monitor the sound being
recorded. You can use the ear hone connected to the
receiver unit to monitor the subject using the
transmitter unit.
• The su lied lavalier micro hone has a built-in
wind screen effect so that you can use the
micro hone in the o en air without a wind screen.
*Plug in ower system
The system that ower is su lied directly to the
micro hone from the micro hone jack of the connected
equi ment.
