NOMENCLATURE AND FUNCTIONS
-
Microphone
Closed type cardioid electret condenser microphone.
The gooseneck shaft makes it easy to position the microphone for optimal acoustic effect. -
Gooseneck lamp
Light blue when the microphone is on and will turn off when the microphone is in off mode. -
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.

Microphone on/off button
Press this key to turn the microphone on or off. -
XLR Output Balance
The microphone output impedance is 750 ohms.
Use the supplied cable to connect it to an amplifier. -
Selector

Battery compartment
Place AA batteries (2 pcs).
BATTERY
Life expectancy
The application and use of the battery for speech and voice is assumed, as
shown in the following table
| Application | 3 hours/week | 3 hours/day | Times* |
|---|---|---|---|
| Discourse | 20 months | 3 months | – |
| Paging | – | – | 92,500 |
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.
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.
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.
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.
