• Maintain a clear line of sight between the receiver and the area where the transmitter will be used.

4.2. પાવર કનેક્શન

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. ઓડિયો આઉટપુટ કનેક્શન

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

• સંતુલિત આઉટપુટ (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 ampજીવંત

4.4. ટ્રાન્સમીટર બેટરી ઇન્સ્ટોલેશન

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. ઓપરેટિંગ સૂચનાઓ

This section details how to operate your MIPRO wireless system.

5.1. પાવર ચાલુ/બંધ

• 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. ખાતરી કરો કે રીસીવર અને ટ્રાન્સમીટર બંને ચાલુ છે.
2. On the ACT-311 receiver, press the એક્ટ 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 સ્કેન કરો બટન
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. વોલ્યુમ ગોઠવણ

Adjust the audio output level of the receiver using the વોલ્યુમ 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 ampજીવંત

5.5. માઇક્રોફોનનો ઉપયોગ

• 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. જાળવણી

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

6.1. સફાઈ

• Wipe the receiver and transmitter with a soft, dry cloth.
• હઠીલા ગંદકી માટે, સહેજ ડીનો ઉપયોગ કરોamp કાપડ અને પછી સારી રીતે સૂકવી.
• Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or internal components.
• Periodically clean the microphone grille to prevent debris buildup.

6.2. બેટરી રિપ્લેસમેન્ટ

• 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.
• જો ટ્રાન્સમીટર લાંબા સમય સુધી ઉપયોગમાં ન આવે તો લીકેજ અટકાવવા માટે બેટરીઓ દૂર કરો.

6.3. સંગ્રહ

• Store the system in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity.
• If transporting, use a protective case to prevent physical damage.

7. મુશ્કેલીનિવારણ

If you encounter issues with your MIPRO wireless system, refer to the following common problems and solutions.

7.1. કોઈ અવાજ નથી

• પાવર તપાસો: Ensure both the receiver and transmitter are powered on and their respective power indicators are lit.
• કનેક્શન્સ તપાસો: Verify that the receiver's audio output is correctly connected to your mixer/amplifier and that all cables are secure.
• વોલ્યુમ તપાસો: Ensure the receiver's volume control is not set to minimum and that your mixer/amplifier input gain is appropriately set.
• Check Frequency: Confirm that the transmitter and receiver are synchronized to the same frequency. Perform ACT synchronization if necessary.
• બેટરી તપાસો: Replace the batteries in the handheld transmitter if they are low or depleted.

7.2. Interference or Signal Dropouts

• રીસીવર પ્લેસમેન્ટ: Relocate the receiver to a higher position or away from metal objects and other electronic devices that may cause interference.
• એન્ટેના પોઝિશન: 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.
• ઓપરેટિંગ રેન્જ: Ensure the transmitter is within the recommended operating range of the receiver.
• બેટરી સ્તર: Low transmitter batteries can cause signal instability. Replace them if needed.

7.3. Poor Sound Quality (Distortion, Weak Signal)

• Microphone Proximity: Ensure the microphone is held at an appropriate distance from the sound source (typically 2-6 inches).
• ગેઇન સેટિંગ્સ: Adjust the input gain on your mixer/amplifier. If the signal is too hot, it can cause distortion; if too low, it will be weak.
• બેટરી સ્તર: Weak batteries can affect audio quality. Replace them.
