Орнотуу нускамалары

1. Receiver Connection

1. Антенналарды туташтыруу: Screw the two detachable antennas onto the ANT-1 and ANT-2 connectors on the receiver's rear panel. Ensure they are standing freely for optimal signal reception.
2. Электр камсыздоо: Connect the included power adapter to the DC Power Supply (12V) input on the receiver. Alternatively, you can use a 5V USB power bank connected to the USB 5V Power Supply (Type-C) input.



3. Аудио чыгаруу: Кабыл алгычты аудио миксериңизге туташтырыңыз, amplifier, or sound system using either the XLR Balanced Audio Output Sockets (BALANCED-1, BALANCED-2) for professional connections or the Unbalanced Mixing Audio Output Socket (MIX OUT) for standard connections.
4. Күйгүзүү: Press the Power Switch on the receiver's front panel to turn it on.

2. Bodypack өткөргүчүн орнотуу

1. Батарея орнотуу: Open the battery compartment on the bodypack transmitter and insert two AA batteries, ensuring correct polarity.



2. Микрофон туташуу: Plug your chosen lavalier or headset microphone into the 3.5mm Mic Input socket on the bodypack transmitter.
3. Күйгүзүү: Press the Power Button on the bodypack transmitter to turn it on. The display will light up.

3. Frequency Synchronization (IR SYNC)

Under normal circumstances, the system is pre-configured and ready to use out of the box. If you need to change frequencies or re-sync, follow these steps:

1. Жыштыкты тандаңыз: On the receiver, use the UP/DOWN buttons to select your desired frequency.
2. Өткөргүчтү даярдоо: Turn on the bodypack transmitter.
3. Инфракызыл портторду тегиздөө: Position the IR emission window of the bodypack transmitter approximately 10-20 cm (4-8 inches) from the IR signal light on the receiver.



4. Initiate SYNC: Press the SET button on the receiver. The receiver's RF signal light will flash, indicating it's searching for the transmitter.
5. Confirm SYNC: Once synchronized, the receiver's RF signal light will stop flashing and remain solid, and the transmitter's frequency will match the receiver's. This indicates a successful connection.

Эскертүү:

• If synchronization fails, repeat the steps.
• When synchronizing multiple transmitters, ensure only one transmitter's IR port is exposed to the receiver at a time to prevent them from pairing to the same frequency, which can shorten the microphone's effective use distance.

Операция

Жыштыкты жөндөө

To change the operating frequency, use the UP/DOWN buttons on the receiver to select a new frequency, then perform the IR SYNC process as described above.

Anti-feedback Function

The system features a multi-level anti-feedback function to prevent howling. You can activate this function by pressing the Anti-feedback button on the receiver's front panel. Be aware that activating this function may slightly affect the sound quality.

Үнсүз функция

To mute the bodypack transmitter, briefly press the ON/OFF button (do not long press). The transmitter's screen will display "AF OFF", indicating that the receiver will no longer receive audio signals from that transmitter. To unmute, briefly press the ON/OFF button again.

Locking/Unlocking Frequency

To prevent accidental frequency changes, you can lock the frequency on the receiver:

1. Кулпу: Long press the SET button on the receiver for approximately 10 seconds. A "key" icon will appear on the screen, indicating the frequency is locked.
2. Кулпуну ачуу: To change the frequency, you must first unlock it. Long press the SET button for another 10 seconds until the "key" icon disappears.

Батареяга мониторинг

Both the receiver and bodypack transmitters feature battery level indicators on their LCD screens. Regularly check these indicators. If the battery power is low, replace the batteries in the transmitters promptly. Low battery power can negatively impact the working range and sound quality.

Иштөө диапазону

The system has an effective working range of over 50 meters (164 feet) in environments free from obstacles and significant interference. Performance may vary depending on environmental conditions.
