Friday, September 26, 2014 | Labels: , , , , , | 0 comments |
Who doesnt have a DVD player today! I know, everybody has one, but I wonder who will have a DVD Player for $20,000! Yes, you read it right. Meridian Audio Ltd presents to you their exclusive range of DVD Players. The company manufactures the worlds most expensive DVD playback machine with prices starting at $19,950.

Worlds Most Expensive DVD Player by Meridian Audio for $20,000!

I am sure you must be thinking of what will you get in return for $20,000! Robert Stuart, the co-founder of Meridian rephrased the question to What do you get for so little? The Model 800 DVD Player is believed to be the pinnacle in audio and video processing technologies. The player plays video recorded in the American NTSC and European PAL systems and uses proprietary software to decode the audio, complex processing to increase picture resolution and extra buffer memory.

So, if you are the one who have a passion for all the most expensive stuff then this superb high definition DVD Player is just for your HDTV!!!![via]

Build 32 Watt Amplifier Circuit Using by TDA2050V. A 32 Watt per channel stereo power amplifier made using the TDA2050V monolithic integrated circuit.

 32 Watt Amplifier Circuit Diagram


32 Watt Amplifier Circuit Using by TDA2050V


Notes:

This circuit is for a 32 Watt stereo audio power amplifier using the TDA20501. With a dual 22 Volt supply this amplifier can deliver 32W into 8 ohm loudspeakers. Moreover, the TDA 2050 delivers typically 50W music power into 4 ohm load over 1 sec at VS= 22.5V and f = 1KHz. The amplifier is cased as a Pentawatt package see pinout below:


TDA2050V

This is a power amplifier and requires 200mV RMS for full output. Voltage gain is 30.5dB with resistor values shown. Closed loop gain is set by Ratio R1/R2. Increase R2 for less gain and vice versa. Power bandwidth is 20Hz to 80KHz. R3, C3 and R6, C11 form a zobel network to prevent high frequency instability.

The speaker is direct coupled, therefore no expensive large value electrolytics are needed and the bass will be crisp and clean. It is advisable to place fuses in the power supply (not shown).

Parts List:

R1,R4,R5,R8______22k 1/4W Resistor
R2,R7__________680R 1/4W Resistor
R3,R6___________2.2R 1/4W Resistor
C1,C10___________1u NP 25V Capacitor
C2,C12__________22u 63V Electrolytic
C3,C11_________0.47u 400V Polyester
C4,C7,C8,C9_____100n 400V Polyester
C5,C6,C13,C14___220u 63V Electrolytic
U1,U2__________TDA2050V 32W Audio Power Amp
