1. المقدمة
The Nobsound HiFi 6P6P Vacuum Tube Push-Pull Amplifier is designed to provide a high-fidelity audio experience. This amplifier utilizes four 6P6P vacuum tubes in a push-pull configuration, combined with an OPA2604 driver stage, to effectively filter digital sound from audio sources. This design significantly reduces background noise and enhances dynamic performance, delivering a harmonious, warm, detailed, and smooth sound characteristic of vacuum tube amplifiers. It is suitable for driving common bookshelf speakers and high-sensitivity floor-standing speakers.

5. الإعداد
5.1 فك العبوة والتفتيش
- قم بإزالة ampمكبر الصوت وجميع الملحقات الموجودة في العبوة.
- Inspect all components for any signs of damage during transit. If any damage is found, contact your retailer immediately.
5.2 تركيب الأنبوب
The 6P6P vacuum tubes may be shipped separately to prevent damage. Install them as follows:
- Identify the four tube sockets on the top panel of the ampمكبر.
- Carefully align the pins of each 6P6P vacuum tube with the corresponding holes in the socket. The tubes are keyed, so they will only fit in one orientation.
- Gently push each tube straight down into its socket until it is firmly seated. Do not force the tubes.

5.3 Connecting Audio Sources (RCA Input)
Connect your audio source (e.g., CD player, DAC, phone, tablet, TV set-top box, computer) to the RCA input terminals on the rear panel of the ampمكبر.
- Use high-quality RCA cables.
- Connect the left channel (white/L) output of your source device to the left RCA input of the ampمكبر.
- Connect the right channel (red/R) output of your source device to the right RCA input of the ampمكبر.

5.4 Connecting Speakers (Banana Plug Output)
Connect your passive speakers to the banana plug output terminals on the rear panel. The amplifier supports both 4Ω and 8Ω speakers.
- تأكد من amplifier is turned off before connecting speakers.
- Connect the positive (+) terminal of your left speaker to the corresponding positive terminal (4Ω or 8Ω, depending on your speaker's impedance) for the left channel on the ampمكبر.
- Connect the negative (-) terminal of your left speaker to the corresponding negative terminal (G) for the left channel on the ampمكبر.
- Repeat the process for the right speaker, connecting it to the right channel output terminals.
- تأكد من أن جميع التوصيلات آمنة لمنع حدوث دوائر قصيرة.


5.5 توصيل الطاقة
- Connect the provided power cord to the IEC power inlet on the rear panel of the ampمكبر.
- قم بتوصيل الطرف الآخر من سلك الطاقة بمقبس حائط مناسب.

6. تعليمات التشغيل
6.1 تشغيل/إيقاف التشغيل
- لتشغيل amplifier, press the power switch located on the front panel. The power indicator lamp سوف تضيء.
- Allow a few moments for the vacuum tubes to warm up before expecting optimal sound. This warm-up period is normal for tube ampالقاتلون.
