5. Panduan Persediaan

Follow these steps to set up your WM301 wireless microphone system:

5.1 Penempatan dan Sambungan Penerima

1. penempatan: Position the receiver unit on a stable, flat surface, or install it into a standard audio rack using the provided rack-mountable hardware. Ensure adequate space for ventilation.
2. Sambungan Antena: Screw the two telescopic antennas firmly into the antenna jacks on the rear of the receiver. Extend them fully and position them vertically for optimal signal reception.
3. Output Audio: Connect the receiver's audio output to your mixer, amplifier, or sound system. You can use either the balanced XLR output or the 1/4'' unbalanced output, depending on your equipment.
   • Keluaran XLR: For professional balanced connections, offering better noise rejection over long cable runs.
   • 1/4'' Output: For standard unbalanced connections.
4. Sambungan Kuasa: Connect the provided power adapter to the DC input on the receiver and then plug it into a suitable power outlet. Do not power on the unit yet.

5.2 Microphone Preparation

1. Pemasangan Bateri: Unscrew the bottom part of each handheld microphone to reveal the battery compartment. Insert the required batteries (typically AA, refer to microphone markings) ensuring correct polarity (+/-).
2. Hidupkan/Mati Kuasa: Locate the power switch on each microphone. Ensure they are in the OFF position during initial setup.

Figure 1: Technical Pro WM301 Wireless Microphone System. The image displays the receiver unit with two extended antennas, and two handheld microphones resting on top. The receiver's front panel shows volume knobs, AF/RF indicators, and a digital display indicating "CHANNEL A 258.7 MHz" and "CHANNEL B 233.7 MHz". Each microphone also has a small LCD screen displaying channel and frequency information.

6. Arahan Operasi

Setelah sistem disediakan, ikuti langkah-langkah ini untuk operasi:

6.1 Menghidupkan Sistem

1. Kuasa Penerima: Turn on the power switch on the front panel of the WM301 receiver. The display should illuminate.
2. Kuasa Mikrofon: Turn on the power switch on each handheld microphone. The microphone's LCD display should light up, indicating its channel and frequency.
3. Pelarasan Kelantangan: Start with the VOLUME A and VOLUME B knobs on the receiver set to a low level. Adjust the volume on your connected mixer or amplifier first, then fine-tune the individual microphone volumes on the receiver.

6.2 Channel Synchronization (if applicable)

The WM301 system typically comes pre-synchronized. If you need to change channels or re-sync, consult the specific instructions for your model, usually involving a scan or IR sync function. The LCD displays on both the receiver and microphones will show the active frequencies (e.g., 258.7 MHz, 233.7 MHz).

6.3 Using the Microphones

• Hold the microphone approximately 2-6 inches (5-15 cm) from your mouth for optimal sound pickup.
• The uni-directional (cardioid) polar pattern helps to focus on the sound source directly in front of the microphone, reducing background noise.
• Monitor the AF (Audio Frequency) and RF (Radio Frequency) indicators on the receiver. The RF indicator should be lit when the microphone is on and within range. The AF indicator will light up when audio is being received.
• Maintain line-of-sight between the microphones and the receiver whenever possible to ensure the best signal quality and range.

6.4 Powering Off the System

1. Turn off each handheld microphone first.
2. Turn off the power switch on the WM301 receiver.
3. Unplug the power adapter from the wall outlet if the system will not be used for an extended period.

7. Penyelenggaraan

Proper maintenance ensures the longevity and performance of your WM301 system:

• Pembersihan: Gunakan kain lembut dan kering untuk membersihkan penerima dan mikrofon. Jangan gunakan pembersih cecair atau bahan kasar.
• Penggantian Bateri: Replace microphone batteries when the low battery indicator appears on the microphone's display or when audio quality degrades. Always replace both batteries in a microphone at the same time.
• Storan: When not in use, store the system in a cool, dry place, away from direct sunlight and extreme temperatures. Remove batteries from microphones if storing for extended periods to prevent leakage.
• Antena: Kendalikan antena dengan berhati-hati untuk mengelakkan bengkok atau patah.
