دليل مستخدم مُخفِّف الصوت AtlasIED E408-250 المُثبَّت على لوحة بقدرة 250 واط

1. انتهى المنتجview

The AtlasIED E408-250 is a plate-mounted attenuator specifically designed for precise level control in masking and sound reinforcement systems. It features a 10-position, non-shorting rotary switch that allows for fine-tuning of audio levels. Each step of the rotary switch provides an attenuation rate of 1.5 dB, offering granular control over the sound output.

The attenuator typically connects in series with the speaker line. Ensure power to the amplifier is off before making any connections to prevent damage to the equipment or injury.

3. تعليمات التشغيل

The AtlasIED E408-250 features a simple rotary knob for adjusting the audio level. The knob has 10 distinct positions, labeled from 0 to 10, providing precise control over the attenuation.

• ضبط المستوى: Rotate the knob clockwise to increase the sound level (less attenuation) and counter-clockwise to decrease the sound level (more attenuation).
• Attenuation Rate: Each step of the rotary switch provides an attenuation of 1.5 dB. This allows for fine adjustments to achieve the desired sound level in your environment.
• Non-Shorting Design: The switch is designed to be non-shorting, meaning it will not create a short circuit when transitioning between positions.
• No Stop: The rotary switch does not have a physical stop at position 0 or 10, allowing for continuous rotation. However, the attenuation range is defined by the 0-10 scale.

4. الصيانة

The AtlasIED E408-250 attenuator is designed for long-term, reliable operation with minimal maintenance. Follow these guidelines to ensure its longevity:

• تنظيف: Use a soft, dry cloth to wipe the surface of the attenuator plate. Avoid abrasive cleaners, solvents, or excessive moisture, which can damage the finish or internal components.
• تقتيش: قم بفحص توصيلات الأسلاك بشكل دوري للتأكد من أنها آمنة وخالية من التآكل.
• بيئة: Ensure the attenuator is installed in a dry environment, away from direct sunlight, extreme temperatures, and high humidity.

5. استكشاف الأخطاء وإصلاحها

If you experience issues with your AtlasIED E408-250 attenuator, consider the following common troubleshooting steps:

• لا يوجد صوت أو صوت منخفض:
  • تحقق من جميع توصيلات الأسلاك للتأكد من أنها آمنة ومثبتة بشكل صحيح.
  • Verify that the attenuator knob is not set to '0' (maximum attenuation).
  • تأكد من amplifier connected to the attenuator is powered on and functioning correctly.
  • Confirm that the speakers are properly connected and operational.
• الصوت المتقطع:
  • افحص الأسلاك بحثًا عن وصلات مفكوكة أو عازل تالف.
  • Ensure the attenuator knob is clean and free of debris that might interfere with its contact points.
• الصوت المشوه:
  • Verify that the attenuator is rated for the power output of your amplifier (E408-250 is 250W). Overpowering can cause distortion or damage.
  • Check other components in the audio chain (amplifier, speakers) for issues.

If the problem persists after attempting these steps, contact Atlas Sound customer support or a qualified audio technician.
