The rear panel provides all input and output connections. This includes XLR/TRS combo jacks for microphone/line inputs, D-Sub connectors for line inputs and outputs/sends, ADAT and AES/EBU digital outputs, Wordclock I/O, and a USB port for computer connectivity. The power inlet is located on the far left.

4. دليل الإعداد

4.1 التفريغ والتنسيب

• Carefully remove the PureDrive Octo from its packaging.
• Place the unit in a well-ventilated area, preferably in a standard 19-inch equipment rack. Ensure adequate airflow around the unit to prevent overheating.
• تجنب وضع الوحدة بالقرب من مصادر الحرارة أو في ضوء الشمس المباشر.

4.2 توصيل الطاقة

• تأكد من أن مفتاح الطاقة الخاص بالجهاز في وضع الإيقاف.
• Connect the supplied AC power cable to the IEC inlet on the rear panel of the PureDrive Octo.
• Plug the other end of the power cable into a grounded AC outlet.

4.3 اتصالات الصوت

• مدخلات الميكروفون: Connect microphones to the XLR inputs on the rear panel (Channels 1-8).
• مدخلات الخط: Connect line-level sources using TRS jacks or the dedicated D-Sub connectors on the rear panel.
• المخرجات الرقمية: Connect the ADAT OUT ports to your audio interface or digital mixer for multi-channel digital audio. Use AES/EBU outputs for stereo digital audio.
• اتصال USB: Connect the USB port on the rear panel to your computer for use as an audio interface. Install necessary drivers if prompted by your operating system.
• ساعة الكلمات: For synchronization with other digital audio devices, connect a Wordclock cable to the WORDCLOCK IN/OUT ports.

5. تعليمات التشغيل

5.1 تشغيل/إيقاف التشغيل

• To power on, flip the power switch on the rear panel to the ON position.
• لإيقاف التشغيل، قم بتحريك مفتاح الطاقة إلى وضع الإيقاف.

5.2 Channel Controls (Per Channel)

• مقبض الربح: Adjusts the input gain for the microphone preamplifier. Use this to set the primary signal level.
• TRIM Knob: Provides fine-tuning of the output level in 1 dB increments. This allows for precise level matching and can be used to drive the signal into the DRIVE circuit.
• زر +48 فولت: Engages phantom power for condenser microphones. Ensure the microphone is connected before activating.
• POLARITY Button: Inverts the phase of the input signal. Useful for correcting phase issues when using multiple microphones.
• HPF Button: Activates a High Pass Filter to reduce unwanted low-frequency rumble or proximity effect.
• Z.D. (Impedance) Button: Cycles through four input impedance options. Experiment with different settings to find the optimal tonal response for your microphone.
• PURE/DRIVE Button: Toggles between the PURE and DRIVE preamp الأوضاع.
  • PURE Mode: Provides a clean, transparent, and linear ampالتصفية.
  • DRIVE Mode: Introduces harmonic saturation and warmth. The PureDrive Octo also features an 'Asymmetric' DRIVE option for unique tonal shaping.

5.3 A/D Conversion and Digital Output Controls

• مقبض المعدل: يختار sample rate for the A/D converters (e.g., 44.1kHz, 48kHz, 88.2kHz, 96kHz).
• زر الساعة: Selects the clock source (Internal, Wordclock, USB).
• القياس: The front panel features LED meters for each channel, providing visual feedback on input levels.

6. الصيانة

• تنظيف: استخدم قطعة قماش ناعمة وجافة لتنظيف الجزء الخارجي من الجهاز. تجنب استخدام المنظفات الكاشطة أو المذيبات.
• تهوية: تأكد من عدم انسداد فتحات التهوية لمنع ارتفاع درجة الحرارة.
• تخزين: When not in use for extended periods, store the unit in a cool, dry environment, away from dust and extreme temperatures.

7. استكشاف الأخطاء وإصلاحها

• لا يوجد طاقة:
  • Check if the power cable is securely connected to both the unit and the AC outlet.
  • تأكد من أن منفذ الطاقة يعمل.
• لا يوجد مخرج صوتي:
  • Ensure all audio cables are correctly connected to the inputs and outputs.
  • Check the GAIN and TRIM settings on the relevant channels.
  • Verify that the correct input source is selected on your receiving device (audio interface, mixer).
  • If using digital outputs (ADAT, AES/EBU, USB), ensure sample rates and clocking are correctly synchronized between devices.
• صوت مشوه:
  • Reduce the GAIN or TRIM level to prevent clipping.
  • Check the input level of your microphone or line source.
  • Ensure the PURE/DRIVE mode is set as desired; DRIVE mode intentionally adds harmonic distortion.
