Ø
Manual station search: Slightly press the DOWN or UP key (held for not more than 1 second), and the equipment
will step once (50kHz per step for FM, and 9kHz per step for AM) towards high frequency or low frequency, and
the corresponding frequency will be displayed on the screen. Manual station search is suitable for searching a
station of which signal is weak.
Ø

dynamic and condenser microphones can be used. When the phantom power supply is switched to “PHANTOM”
position, a condenser microphone is available; when the phantom power supply is switched to “MIC” position, a
dynamic microphone is available.
To avoid strong feedback, please adjust the microphone volume down through the microphone volume knob on
the front panel before plugging the microphone. Since all microphones adopt XLR interface, please check the
direction when connecting. The gain of the microphone can be adjusted through “GAIN” knob for the best voice

effect.
“PRIORITY” terminal on the rear panel for microphone features Mute function when a short-circuit signal is
inputted. (Except chime signal), other signals can be suppressed by the signal from the four microphones. When
“PRIORITY” terminal is shorted, both chime and microphone feature Mute function of the same priority. If the
volume of chime is minimized, microphone signal can be outputted individually. The Mute function can be
canceled by canceling the short-circuit signal.
5． Built-in Chime Generator
Chime signal of the equipment can be outputted by short-circuit toggle through “PRIORITY” terminal on the
rear panel. Short-circuit once, and the chime signal will be outputted once. If another chime signal is desired,
cancel the current short-circuit and short the “PRIORITY” terminal again. The output volume of chime can be
adjusted by “CHIME VOL” knob. Since chime features overriding function, it is suitable for forced insertion.
