2. تعليمات السلامة
To prevent electric shock, fire, or damage to the amplifier, always observe the following safety precautions:
- مزود الطاقة: قم بتوصيل amplifier only to an AC power supply of the voltage specified on the rear panel. Ensure the power cable is in good condition and properly grounded.
- تهوية: لا تسد فتحات التهوية. تأكد من تدفق الهواء الكافي حول amplifier لمنع ارتفاع درجة الحرارة.
- رُطُوبَة: لا تعرض amplifier to rain, moisture, or excessive humidity. Keep liquids away from the unit.
- الخدمة: لا تحاول خدمة amplifier yourself. Refer all servicing to qualified service personnel. High voltages موجودة داخل amplifier, even when switched off.
- توصيلات السماعات: قم دائمًا بتوصيل amplifier to a suitable speaker cabinet with the correct impedance before powering on. Operating without a speaker load can damage the output transformer.
- Tube Heat: Vacuum tubes operate at high temperatures. Avoid touching them and allow sufficient cooling time after use.
- حماية السمع: هذا amplifier can produce high sound pressure levels. Prolonged exposure to high volumes can cause permanent hearing damage. Use appropriate hearing protection.
3. الإعداد
3.1 فك التعبئة
قم بإزالة amplifier from its packaging. Retain all packaging materials for future transport or storage. Inspect the amplifier for any signs of damage incurred during shipping. If damage is found, contact your dealer immediately.
3.2 Connecting to a Speaker Cabinet
The DSL100HR requires connection to an external speaker cabinet. Ensure the speaker cabinet's impedance matches one of the amplifier's output jacks (16 Ohm, 8 Ohm, or 4 Ohm). Use a high-quality speaker cable (not a guitar cable) for this connection.
- For a single 16 Ohm cabinet, connect to the '16 Ohm' jack.
- For a single 8 Ohm cabinet, connect to one of the '8 Ohm' jacks.
- For two 16 Ohm cabinets, connect each to an '8 Ohm' jack.
- For a single 4 Ohm cabinet, connect to one of the '4 Ohm' jacks.
- For two 8 Ohm cabinets, connect each to a '4 Ohm' jack.
مهم: لا تقم بتشغيل amplifier without a speaker load connected to the appropriate output jack.
3.3 توصيل الطاقة
Connect the supplied power cable to the IEC inlet on the rear panel of the amplifier and then to a grounded mains power outlet.
3.4 توصيل الغيتار
Connect your guitar to the 'INPUT' jack on the front panel using a standard instrument cable.
3.5 Footswitch Connection
Connect the supplied footswitch to the 'FOOTSWITCH' jack on the rear panel. This allows remote switching between channels and reverb on/off.
4. تعليمات التشغيل
4.1 تشغيل/إيقاف التشغيل
- Ensure all volume controls are set to minimum.
- Switch the 'POWER' switch to the ON position.
- Wait approximately 30-60 seconds for the tubes to warm up, then switch the 'STANDBY' switch to the ON position. The ampمكبر الصوت جاهز الآن للاستخدام.
- To power off, reverse the sequence: 'STANDBY' to OFF, then 'POWER' to OFF.

5. الصيانة
5.1 استبدال الأنبوب
The DSL100HR uses 4 x ECC83 preamp tubes and 4 x EL34 power tubes. Tubes have a finite lifespan and will eventually need replacement. Symptoms of worn tubes include loss of volume, reduced tone quality, excessive noise, or intermittent operation. Tube replacement should ideally be performed by a qualified technician, as it involves working with high voltages and proper biasing of new power tubes is crucial for optimal performance and longevity.
5.2 التنظيف
تنظيف amplifier's exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or waxes. Ensure the amplifier is unplugged before cleaning.
5.3 التخزين
عند عدم الاستخدام لفترات طويلة، قم بتخزينه amplifier in a dry, temperature-controlled environment, away from direct sunlight and extreme temperatures. Using a protective cover can help prevent dust accumulation.
