1. Microphone
Closed type cardioid electret condenser microphone.
The gooseneck shaft makes it easy to position the microphone
for optimal acoustic effect.
2. Gooseneck lamp
Light blue when the microphone is on and will turn off when the
microphone is in off mode.
3. Ignition lamp
Like the gooseneck lamp, the power lamp will turn on when the
microphone is on and turn off when the microphone is off.
Note: If the battery is low, the lamp will turn off, but the
microphone can still be used.
It is recommended to change the battery when this happens.
4. Microphone on/off button
Press this key to turn the microphone on or off.
5.XLR Output Balance
The microphone output impedance is 750 ohms.
Use the supplied cable to connect it to an amplifier.
6. Selector
Select this switch to use battery or phantom as the power supply
for this unit.
Note: It is recommended to use the supplied cable or a b-to-
lance cable, especially if you use phantom power. Otherwise,
the gooseneck lamp and the ignition lamp are dimly lit, although
the unit may function normally.
7. Battery compartment
Place AA batteries (2 pcs).

5.2. Battery insertion
Step 1. Open the battery cover.
Step 2. Insert batteries according to the polarity of the battery and make sure that the tape
remaining is on top of the batteries. (see image on the right).
Step 3. Put the battery cover back on the product.
Caution: If the microphone is not to be used in more than 1 month, remove the battery from the unit to
prevent battery leakage. To remove the batteries, carefully pull the remaining tape from the
battery compartment.
6. CONNECTION
Step 1. Place the amplifier microphone volume control
in the minimum position.
Step 2. Use the supplied cable to connect the microphone
the microphone unit to the microphone input of the amplifier.
7. OPERATION
Step 1. Press the ON/OFF button on the microphone.
The gooseneck lamp and the power lamp turn on and turn on the microphone.
Step 2. Make an announcement.
Keep your mouth at a distance of 5 to 10 cm from the microphone and speak normally for the best playback of
sound possible. Adjust the microphone orientation for the best position by rotating the axis of the gooseneck. If the distance from
the mouth is too close, this causes distortion of the voice, just the microphone by pulling it or lowering it, because the microphone
is of high sensitivity.
Step 3. Once the announcement is complete, press the ON/OFF button on the microphone.
Both the unit lamp and microphone will turn off.
Note: Be sure to press the ON/OFF button after completing the ad. Failure to do so reduces battery life.
8. USING SELECTOR SWITCH MODE
The selector switch has 2 modes. There is battery mode and ghost mode. If you use the battery as a power input, select the switch to the
battery position. And if you use ghost as an energy input, select the ghost position. Be sure to turn on the phantom power from the
amplifier or mixer. For reference, you can use the phantom power of TOA mixer amplifiers.
