5. 操作手順

5.1. 音量コントロール

Each channel on the receiver unit has an independent volume control knob. Adjust these knobs to set the desired output level for each microphone. For optimal sound, it is often recommended to manage overall volume through your connected soundboard or amplifier。

5.2. マイクの使用方法

The PRORECK MX44 microphones are unidirectional (cardioid pickup pattern). For best sound quality and to minimize background noise, speak directly into the top of the microphone, keeping it relatively close to your mouth. This design focuses on capturing sound from the intended source.

5.3. 動作範囲

The system offers an operating range of up to 200 feet within line of sight. Ensure there are no major obstructions between the microphones and the receiver for consistent signal quality.

5.4. EQモード

The receiver features 8 kinds of EQ modes (e.g., JAZZ, POP, COUNTRY, ROCK). Refer to the receiver's controls for adjusting these modes to suit your audio preferences and application.

5.5. 推奨される用途

This system is versatile and suitable for a wide range of indoor and outdoor activities, including:

• パーティー
• 教会の礼拝
• スピーチ
• 結婚式
• Family Gatherings
• 会議

6. メンテナンス

6.1. バッテリーの交換

Each microphone requires two AA batteries. When the microphone's display indicates low power, replace the batteries promptly. Note that some slightly oversized AA batteries may be difficult to insert or remove. Standard alkaline or rechargeable NiMH batteries (like Eneloop) are generally recommended for best fit and longevity. The system is not compatible with rechargeable batteries that require external charging via the microphone itself.

6.2. 清掃

Wipe the receiver and microphones with a soft, dry cloth. Avoid using liquid cleaners or abrasive materials, as they may damage the finish or internal components.

6.3. Microphone Grill

The microphone grill can be unscrewed and removed for cleaning or replacement if it becomes damaged.

7。 トラブルシューティング

• マイクから音が出ない:
  • Ensure both the receiver and microphones are powered on.
  • Check microphone batteries and replace if low or depleted.
  • Verify that the microphone's frequency and channel match the receiver's display for the corresponding channel.
  • Confirm that audio cables are securely connected from the receiver to your sound system.
  • Adjust volume knobs on the receiver and your sound system.
• System Does Not Power On After Outage:

  If power is interrupted, the receiver may not automatically power back on. Manually press the power button on the receiver to turn it back on.
• Signal Drop or Interference:
  • Ensure the receiver's antennas are properly extended and positioned.
  • Minimize obstructions between the microphones and receiver.
  • Avoid placing the receiver near other wireless devices or strong electromagnetic fields.
  • Note: Two sets of PRORECK MX44 systems cannot be used together due to fixed frequencies (607.5/615.5/653.1/658.3MHz).
