3. الإعداد
3.1 فك التعبئة
قم بإزالة amplifier from its packaging. Inspect the unit for any signs of damage that may have occurred during transit. Retain the original packaging for future shipping or storage.
3.2 التنسيب والتركيب
The RMX5050 is designed for standard 19-inch rack mounting and occupies 3U of rack space. Ensure the rack provides sufficient ventilation and structural support for the amplifier's weight (approximately 75 pounds).
3.3 الاتصالات
قبل إجراء أي اتصالات، تأكد من amplifier is powered off and disconnected from the AC mains.
3.3.1 اتصالات الإدخال
The RMX5050 features balanced 1/4" TRS, XLR, and barrier strip inputs for flexible connectivity. Connect your audio source (mixer, preamplifier, etc.) to the appropriate input connectors for Channel 1 and Channel 2.
3.3.2 اتصالات الإخراج
قم بتوصيل مكبرات الصوت الخاصة بك بـ amplifier's outputs using either binding posts or Neutrik Speakon connectors. Ensure correct polarity and impedance matching for optimal performance and to prevent damage to speakers or the ampمكبر.

3.3.3 توصيل الطاقة
قم بتوصيل سلك الطاقة المرفق بـ amplifier's power inlet and then to a grounded AC outlet. Verify that the power source matches the amplifier's voltagالمتطلبات.
3.4 التشغيل الأولي
- تأكد من أن كافة الاتصالات الصوتية آمنة.
- Set the front panel gain controls to their minimum (fully counter-clockwise) position.
- Power on your audio source equipment first.
- Flip the power switch on the RMX5050 to the "ON" position. The power indicator LED should illuminate.
- Slowly increase the gain controls to the desired level.
4. تشغيل Ampالقمامة
4.1 ضوابط ومؤشرات اللوحة الأمامية
- مفتاح التشغيل: يبدل amplifier تشغيل / إيقاف.
- مؤشر الطاقة LED: يضيء باللون الأخضر عندما ampتم تشغيل المحرك.
- Gain Controls (Channel 1 & 2): Rotary knobs to adjust the input sensitivity for each channel.
- مؤشر LED للإشارة: Illuminates green when an audio signal is present at the input.
- مقطع LED: Illuminates red when the output signal is clipping (distorting). Reduce input level or gain if this LED frequently illuminates.
- حماية مصابيح LED: يضيء باللون الأحمر إذا كان amplifier enters protection mode due to overheating, short circuit, or other fault conditions.

4.2 Rear Panel DIP Switches
The rear panel features DIP switches that allow configuration of various operating parameters. Always power off the amplifier before changing DIP switch settings.
- Clip Limiter: Engages a circuit that prevents severe clipping and protects speakers.
- Low-Frequency Filters: High-pass filters (e.g., 30 Hz, 50 Hz) to remove unwanted low-frequency content, protecting speakers and improving clarity.
- وضع التشغيل: Selects between Stereo, Parallel, or Bridged Mono operation.
أوضاع التشغيل 4.3
4.3.1 وضع ستيريو
In stereo mode, each channel operates independently, amplifying its respective input signal and sending it to its dedicated output. This is the standard mode for two-channel sound reinforcement.
4.3.2 الوضع الموازي
In parallel mode, a single input signal is fed to both amplifier channels, which then drive separate speaker loads. This is useful for driving multiple speakers with the same mono signal.
4.3.3 Bridged Mono Mode
يجمع الوضع الأحادي الموصّل بين قوة الاثنين amplifier channels into a single, higher-power output. This mode is typically used to drive a single, high-power loudspeaker or subwoofer. Consult the manual for specific wiring instructions for bridged mono operation.
5. الصيانة
5.1 التنظيف
نظف الجزء الخارجي من amplifier with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure ventilation grilles are free from dust and debris.
5.2 التهوية
The RMX5050 relies on internal fans for cooling. Regularly check that the air intake and exhaust vents are not obstructed. Operating the amplifier in poorly ventilated spaces can lead to overheating and activation of protection circuits.

5.3 التخزين
إذا تم تخزين amplifier for an extended period, ensure it is kept in a dry, temperature-controlled environment, away from direct sunlight and extreme temperatures. It is recommended to use the original packaging for protection.
