4.1 ضوابط اللوحة الأمامية

Image: Front panel of the Warm Audio WA12 MKII, showing all controls and indicators.

• 1/4" Instrument DI Input: Connect high-impedance instruments such as guitars or basses here.
• زر HI-Z: Engages the high-impedance input for instruments, optimizing the signal path.
• زر 48V: Activates +48V phantom power for condenser microphones. An indicator LED illuminates when active.
• زر لوحة المفاتيح: Applies a -20dB attenuation to the input signal, useful for very loud sources to prevent clipping.
• POL (Polarity) Button: Inverts the polarity (phase) of the input signal. Useful for correcting phase issues when using multiple microphones.
• زر النغمة: Engages a tone-shaping circuit that alters the input impedance from 600 ohms to 150 ohms, providing a different sonic character.
• مقبض الربح: Controls the input gain for the microphone or instrument signal, ranging from 29dB to 65dB.
• مقبض الإخراج: يضبط مستوى الإخراج الإجمالي لما قبلampمكبر.
• VU Meter LEDs: A series of LEDs indicating the output level, ranging from -20dB to +18dB, with indicators for 0dB, +08dB, and +18dB (clipping).
• زر الطاقة: Turns the unit on or off. An indicator LED illuminates when the unit is powered on.

4.2 اتصالات اللوحة الخلفية

The rear panel of the WA12 MKII provides the necessary connections for integrating the unit into your audio setup.

• مدخل ميكروفون XLR: Connect your microphone via a standard XLR cable.
• خرج خط XLR: Connect this output to your audio interface, mixer, or other recording equipment.
• مدخلات الطاقة IEC: Connect the provided IEC cable here to power the unit.

5. الإعداد

Follow these steps to set up your Warm Audio WA12 MKII:

1. توصيل الطاقة: Connect the IEC power cable to the rear panel of the WA12 MKII and then to a grounded AC power outlet.
2. اتصال الميكروفون: Connect your microphone to the XLR Microphone Input on the rear panel using a high-quality XLR cable.
3. توصيل الجهاز (اختياري): If using an instrument, connect it to the 1/4" Instrument DI Input on the front panel. Ensure the HI-Z button is engaged.
4. اتصال الإخراج: Connect the XLR Line Output on the rear panel to an input on your audio interface, mixer, or other recording device.
5. تشغيل الطاقة: Press the POWER button on the front panel. The power indicator LED will illuminate.
6. الإعدادات الأولية: Set the GAIN and OUTPUT knobs to their minimum positions before connecting any audio sources to avoid sudden loud signals.

6. تعليمات التشغيل

Operating the WA12 MKII involves adjusting its various controls to achieve the desired sound and level.

• كسب S.tagعمل: Begin by slowly increasing the GAIN knob until the desired input level is achieved. Monitor the VU Meter LEDs to ensure the signal is not clipping (red +18dB LED). Adjust the OUTPUT knob to control the signal level sent to your recording device.
• Phantom Power (48V): If using a condenser microphone, press the 48V button to supply phantom power. Always connect the microphone before engaging phantom power and disengage it before disconnecting the microphone.
• الوسادة: For very loud sources (e.g., close-miked drums, loud guitar amps), engage the PAD button to reduce the input signal by 20dB, preventing distortion.
• Polarity (POL): Use the POL button to invert the phase of the input signal. This can be crucial when recording with multiple microphones to avoid phase cancellation issues.
• نغمة: The TONE button changes the input impedance, offering a different sonic flavor. Experiment with this setting to find what best suits your microphone and source.
• HI-Z: When connecting an instrument directly to the 1/4" input, ensure the HI-Z button is engaged for proper impedance matching.

7. الصيانة

Proper maintenance will ensure the longevity and optimal performance of your WA12 MKII.

• تنظيف: استخدم قطعة قماش ناعمة وجافة لتنظيف الجزء الخارجي من الجهاز. تجنب استخدام المنظفات الكاشطة أو المذيبات.
• تخزين: عند عدم الاستخدام، قم بتخزين الوحدة في مكان بارد وجاف بعيدًا عن أشعة الشمس المباشرة ودرجات الحرارة القصوى.
• تهوية: Ensure the unit has adequate airflow around it during operation to prevent overheating.
• العناية بالكابلات: Handle all cables with care. Avoid bending or crimping them excessively.

8. استكشاف الأخطاء وإصلاحها

If you encounter any issues with your WA12 MKII, refer to the following common problems and solutions:

• لا يوجد طاقة:
  • Check if the IEC cable is securely connected to the unit and the power outlet.

  • If using an instrument, ensure the HI-Z button is engaged.
  • Check the input/output settings on your audio interface or mixer.
• الصوت المشوه:
  • قم بتقليل مستوى الكسب (GAIN).
  • Engage the PAD button if the source is very loud.
  • Check the input level on your recording device to ensure it's not clipping.
• همهمة أو ضجيج:
  • تأكد من أن جميع الكابلات محمية ومتصلة بشكل صحيح.
  • حاول استخدام منفذ طاقة مختلف.
