D-450 Quad Receiver

The D-450 receiver is an all-metal, rack-mountable unit featuring four independent receiver channels. It provides 200 selectable frequencies (50 per channel) in the 500 MHz band, ensuring interference-free operation. The front panel includes LCD displays for each channel, showing frequency, battery status, and RF signal indicators. The rear panel offers individual balanced XLR microphone level outputs for each channel and a single 1/4-inch line level sum output for all four receivers.

සැලසුම

1. ග්‍රාහක සැකසුම

1. ස්ථානගත කිරීම: Position the D-450 receiver in a stable location, preferably within line-of-sight of the intended operating area for the transmitters. Ensure adequate ventilation.
2. ඇන්ටනා: Screw the four supplied antennas onto the corresponding connectors on the front panel of the receiver. Adjust them vertically for optimal reception.
3. බලය: Connect the supplied power adapter to the DC input jack on the rear of the receiver and plug it into an AC outlet.
4. ශ්‍රව්‍ය ප්‍රතිදානය: Connect the receiver to your mixer or amplifier using either the individual balanced XLR outputs (for separate control of each microphone) or the 1/4-inch line level sum output.

2. සම්ප්‍රේෂක සැකසුම

1. Handheld Microphones (HT-450): Unscrew the bottom cap of the HT-450 microphone and insert two fresh AA batteries, observing polarity. Screw the cap back on.
2. Bodypack Transmitters (LT-450): Open the battery compartment on the LT-450 bodypack and insert two fresh AA batteries, observing polarity. Close the compartment.
3. Lapel Microphones (OML-4): Connect the 3.5mm plug of the OML-4 lapel microphone to the locking jack on the LT-450 bodypack. Secure the lapel microphone to clothing, approximately 6-8 inches from the mouth.

3. Pairing Transmitters with Receiver

The D-450 system features auto-scan and infrared (IR) sync for easy pairing.

1. බල ගැන්වීම: Power on the D-450 receiver.
2. ස්වයං-ස්කෑන්: For each receiver channel you wish to use, press the 'MODE' button to initiate an auto-scan. The receiver will search for an available, interference-free frequency.
3. IR සමමුහුර්තකරණය: Once a frequency is selected on the receiver, power on the corresponding transmitter (handheld or bodypack). Open the IR window on the transmitter and align it with the IR sensor on the receiver's front panel. Press the 'SET' button on the receiver. The frequency will be automatically transferred to the transmitter.
4. සත්‍යාපනය: Confirm that the RF indicator on the receiver illuminates, indicating a successful connection with the transmitter.

මෙහෙයුම

බලය සක්රිය / අක්රිය

• ලබන්නා: Press the 'POWER' button on the front panel.
• සම්ප්‍රේෂක: Press and hold the power button on the handheld microphone or bodypack until the display illuminates.

නාලිකා තේරීම

While the auto-scan feature is recommended for initial setup, you can manually select frequencies if needed. Use the 'UP' and 'DOWN' buttons next to each channel's display on the receiver to cycle through available frequencies. Remember to re-sync the corresponding transmitter via IR after changing a frequency on the receiver.

පරිමාව පාලනය

Each receiver channel on the D-450 has an independent volume control knob. Adjust these to achieve the desired audio level before sending the signal to your mixer or amplifier. Further level adjustments can be made on your external audio equipment.

පරාසය සලකා බැලීම්

The Nady D-450 system offers a reliable operating range of over 300 feet line-of-sight. Obstacles such as walls, metal structures, and other wireless devices can reduce this range. Maintain line-of-sight between transmitters and the receiver whenever possible for optimal performance.

නඩත්තු කිරීම

බැටරි ප්රතිස්ථාපනය

Replace batteries in transmitters when the low battery indicator appears on their LCD display or on the receiver's display. Always use fresh, high-quality AA batteries. Remove batteries if the system will not be used for an extended period to prevent leakage.

පිරිසිදු කිරීම

Clean the units with a soft, dry cloth. Do not use liquid cleaners or solvents, as they may damage the finish or internal components.

ගබඩා කිරීම

Store the system in a cool, dry place away from direct sunlight and extreme temperatures. When transporting, use appropriate cases to protect the components from physical damage.
