5. الإعداد والتثبيت

Follow these steps to connect your Monoprice 4-Channel Speaker Selector to your audio system.

5.1 Identify Connections

الشكل 2: Rear panel of the speaker selector. Note the "L INPUTS R" terminals on the left for amplifier connection and "OUTPUTS" terminals (1-4) for speaker connections.

The rear panel of the speaker selector features one set of stereo inputs labeled "L INPUTS R" for connecting your amplifier or receiver, and four sets of stereo outputs labeled "OUTPUTS 1" through "OUTPUTS 4" for connecting your speaker pairs.

5.2 تعليمات الأسلاك

1. إيقاف التشغيل: تأكد من amplifier/receiver is turned off and unplugged from the power outlet before making any connections.
2. Prepare Speaker Wires: Strip approximately 1/2 inch (1.25 cm) of insulation from the ends of all speaker wires. Twist the bare wire strands tightly.
3. يتصل Amplifier to Inputs:
   • قم بتوصيل يسار (+) output terminal of your amplifier إلى يسار (+) input terminal of the speaker selector (under "L INPUTS R").
   • قم بتوصيل اليسار (-) output terminal of your amplifier إلى اليسار (-) input terminal of the speaker selector.
   • قم بتوصيل يمين (+) output terminal of your amplifier إلى يمين (+) input terminal of the speaker selector.
   • قم بتوصيل حق (-) output terminal of your amplifier إلى حق (-) input terminal of the speaker selector.

   تأكد من القطبية الصحيحة (+ إلى + و- إلى -) للحصول على جودة صوت مثالية.

4. Connect Speakers to Outputs: For each pair of speakers (Zone 1, 2, 3, or 4):
   • قم بتوصيل يسار (+) terminal of your speaker to the يسار (+) output terminal for the desired zone on the speaker selector.
   • قم بتوصيل اليسار (-) terminal of your speaker to the اليسار (-) output terminal for the desired zone on the speaker selector.
   • قم بتوصيل يمين (+) terminal of your speaker to the يمين (+) output terminal for the desired zone on the speaker selector.
   • قم بتوصيل حق (-) terminal of your speaker to the حق (-) output terminal for the desired zone on the speaker selector.

   Maintain consistent polarity for all speaker connections.

5. Impedance Protection Switch: Locate the impedance protection switch (often on the rear or bottom of the unit).
   • على: Activates the protection circuit. Recommended for amplifiers with minimum impedance ratings below 8 ohms, or when connecting multiple pairs of speakers simultaneously to prevent amplifier overload. This limits power handling to 70W per channel.
   • OFF: Disables the protection circuit. Allows for higher power handling (up to 140W per channel) but requires careful consideration of your amplifier's minimum impedance rating and the total impedance of connected speakers. Consult your ampدليل مكبر الصوت.
6. الموقع: Place the speaker selector in a well-ventilated area, away from heat sources and direct sunlight.

6. تعليمات التشغيل

Once all connections are made and verified, you can begin using your speaker selector.

1. تشغيل الطاقة: قم بتوصيل وتشغيل ampمكبر / مستقبل.
2. تحديد مناطق مكبرات الصوت: Use the individual push-buttons on the front panel of the speaker selector to turn on or off each pair of connected speakers (Zone 1, 2, 3, or 4).
   • Pressing a button will engage that speaker zone.
   • Pressing it again will disengage the zone.
   • You can select one, multiple, or all speaker zones simultaneously, depending on your listening preference and ampقدرات مكبر الصوت.
3. ضبط مستوى الصوت: Control the overall volume using your amplifier/receiver's volume control.

Note on Impedance Protection: If the impedance protection circuit is enabled, you can safely operate multiple pairs of speakers without concern for amplifier overload. If it is disabled, be mindful of your amplifier's minimum impedance rating when engaging multiple speaker pairs. Operating an amplifier below its minimum impedance rating can cause damage.

7. الصيانة

The Monoprice 4-Channel Speaker Selector requires minimal maintenance.

• تنظيف: استخدم قطعة قماش ناعمة وجافة لمسح الجزء الخارجي من الجهاز. لا تستخدم المنظفات السائلة أو البخاخات.
• تهوية: تأكد من عدم انسداد فتحات التهوية الموجودة على الوحدة لمنع ارتفاع درجة الحرارة.
• الاتصالات: Periodically check all speaker wire connections to ensure they remain secure.
