أخيرًا ، تجلب عائلتنا الجديدة من مكبرات الصوت التلفزيونية التي يتم التحكم فيها رقميًا والموجودة في حاوية الرف مزايا التحكم الرقمي بالكامل. يمكنك الآن ضبط طاقة الإخراج بشكل مريح باستخدام مفاتيح UP / DOWN والتحقق من SWR أو درجة الحرارة الداخلية أو طاقة خرج التردد اللاسلكي في أي وقت بنظرة بسيطة على شاشة LCD. يتم تضمين حماية SWR بالطبع. لا مزيد من البحث إذا كنت تبحث عن مضخم تلفزيون موثوق به مع الراحة والسهولة لنظام التحكم الرقمي الذي يعمل بتقنية LCD.

Employing the latest RF techniques for an ultra-stable high effeciency design. This unit is supplied with a universal input switched mode power supply and is built into a nice looking 2H 19-inch rack enclosure. This can be used with any mains voltage system in the world. A built in heatsink and fan assembly provides more than adequate cooling to the unit ensuring 24/7 operation. On board harmonic filtering provides that needed reassurance that your signal is where it should be. Accepts 5mW input, but can be modified to accept higher power levels.

Why is this VHF TV AMPLIFIER so great?
One might think one of the RF amplifier modules would be enough, but reality is often far from that. Just the basic coaxial cable wiring represents a major problem to many users. Than there’s the issue of SWR protection, which most modules don’t offer, and RF power, SWR and TEMP measurement and display on LCD, which is not just convenient but often helps monitor operation and eliminate the problem fast or even before it happens. Another strong point is the mains power supply, most modules are shipped with PSU that’s just barely able to cope with the load, usually quitting after a couple months, or, as Murhpy would have it, just a few days after warranty expires (in the middle of the top radio show).

A relatively modest additional investment in a better equipment is rewarded by reliable operation, convenience and peace of mind. Here’s a quick summary of the benefits:
– Digital control, you can now adjust output power to a desired value
– Built-in SWR and RF POWER meter
- حماية SWR
– No hassle, easy to use
– Mains operated
– Over-dimensioned mains power supply

Its best that you look at the screen capture below. The program may change slightly over time as we make enhancements, but the main features will remain as below:
You can basically change all available parameters and put unit into standby mode, if desired.
