Follow these steps to set up your MIPRO wireless system.

4.1. Tqegħid tar-Riċevitur

• Place the ACT-311 receiver in a location free from obstructions and away from potential sources of interference (e.g., computers, digital processors, other wireless devices).
• Ensure the receiver's antennas are fully extended and positioned vertically for optimal signal reception.
• Maintain a clear line of sight between the receiver and the area where the transmitter will be used.

4.2. Konnessjoni tal-Enerġija

1. Connect the supplied power adapter to the DC input jack on the rear panel of the ACT-311 receiver.
2. Plug the power adapter into an appropriate AC power outlet.
3. Do not power on the receiver yet.

4.3. Konnessjoni tal-Output tal-Awdjo

Connect the receiver's audio output to your mixer, amplifier, or sound system.

• Ħruġ Ibbilanċjat (XLR): Use an XLR cable to connect the receiver's XLR output to a balanced input on your mixer.
• Unbalanced Output (1/4" Phone Jack): Use a 1/4" phone jack cable to connect the receiver's unbalanced output to an unbalanced input on your mixer or ampaktar ħaj.

4.4. Installazzjoni tal-Batterija tat-Trasmettitur

1. Unscrew the lower part of the ACT-32H handheld microphone to reveal the battery compartment.
2. Insert two fresh AA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
3. Securely screw the lower part back onto the microphone.

5. Istruzzjonijiet Operattivi

This section details how to operate your MIPRO wireless system.

5.1. Tixgħil / Mitfi

• Receiver (ACT-311): Press the power button on the front panel. The LCD display will illuminate.
• Transmitter (ACT-32H): Slide the power switch on the handheld microphone to the "ON" position. The power indicator will light up.
• Always power on the receiver before the transmitter, and power off the transmitter before the receiver.

5.2. Frequency Synchronization (ACT Function)

MIPRO's patented ACT (Automatic Channel Targeting) function allows for quick and precise frequency matching between the receiver and transmitter.

1. Ensure both the receiver and transmitter are powered on.
2. On the ACT-311 receiver, press the ATT button. The ACT indicator on the receiver will flash.
3. Align the ACT sync port on the ACT-32H handheld microphone (usually near the base or battery compartment) with the ACT window on the receiver.
4. Hold them together within a few centimeters until the receiver's ACT indicator stops flashing and the transmitter's frequency display matches the receiver's.
5. The system is now synchronized and ready for use.

5.3. Channel Selection (Auto Scan)

Use the Auto Scan function to find the clearest available frequency channel.

1. On the ACT-311 receiver, press the SKANJA buttuna.
2. The receiver will automatically scan for an interference-free channel.
3. Once a clear channel is found, the receiver will display it.
4. Perform the ACT synchronization process (Section 5.2) to match the transmitter to this newly selected channel.

5.4. Aġġustament tal-Volum

Adjust the audio output level of the receiver using the VOLUM control knob on the front panel of the ACT-311. Start with a low volume and gradually increase it to a suitable level on your mixer or ampaktar ħaj.

5.5. Użu tal-mikrofonu

• Hold the ACT-32H microphone approximately 2-6 inches (5-15 cm) from your mouth for optimal vocal pickup.
• Avoid covering the microphone grille with your hand, as this can affect sound quality and signal transmission.
• Be aware of the microphone's unidirectional polar pattern, which means it primarily picks up sound from the front, reducing background noise.

6. Manutenzjoni

Proper maintenance ensures the longevity and optimal performance of your wireless system.

6.1. Tindif

• Wipe the receiver and transmitter with a soft, dry cloth.
• Għal ħmieġ iebsa, uża ftit damp drapp u mbagħad nixxef sewwa.
• Tużax prodotti tat-tindif li joborxu, solventi, jew kimiċi ħarxa, għax dawn jistgħu jagħmlu ħsara lill-finitura jew lill-komponenti interni.
• Periodically clean the microphone grille to prevent debris buildup.

6.2. Sostituzzjoni tal-batterija

• Replace the AA batteries in the ACT-32H transmitter when the low battery indicator appears on the microphone or receiver, or if you notice a decrease in performance.
• Always use fresh, high-quality alkaline or rechargeable batteries.
• Neħħi l-batteriji jekk it-trasmettitur ma jkunx se jintuża għal perjodu estiż biex tevita t-tnixxija.

6.3. Ħażna

• Store the system in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity.

• Iċċekkja l-Konnessjonijiet: Verify that the receiver's audio output is correctly connected to your mixer/amplifier and that all cables are secure.
• Iċċekkja Volum: Ensure the receiver's volume control is not set to minimum and that your mixer/amplifier input gain is appropriately set.
• Frekwenza tal-Iċċekkjar: Confirm that the transmitter and receiver are synchronized to the same frequency. Perform ACT synchronization if necessary.
• Iċċekkja Batteriji: Replace the batteries in the handheld transmitter if they are low or depleted.

7.2. Interference or Signal Dropouts

• Poġġiment tar-riċevitur: Relocate the receiver to a higher position or away from metal objects and other electronic devices that may cause interference.
• Pożizzjoni tal-antenna: Ensure receiver antennas are fully extended and positioned correctly.
• Scan for Clear Channel: Use the Auto Scan function on the receiver to find a new, clear frequency, then re-synchronize the transmitter.
• Medda operattiva: Ensure the transmitter is within the recommended operating range of the receiver.
• Livell tal-batterija: Low transmitter batteries can cause signal instability. Replace them if needed.
