TDA7294 2.1 Channel Deluxe (Upgrade) Amplifier Board (With Speaker Protection)
Product Details.
Using the European SGS-THOMSON ST Microelectronics in the 90s destroyed a field tube output of the new high-power laser dark TDA7294 integrated circuit. Completely changed the previous integrated amplifier raw, cold, hard tone, widely used in the HI-FI field. The chip is designed to focus on the tone. With high voltage resistance, low noise, low distortion, soft playback tone, and short-circuit current and overheating protection function
1. power supply filtering using six 50V 3300UF Nikon capacitors, rectification using 25A imported rectifier flat bridge.
2. PCB using 1.6mm thick double-sided plate, 2.0 Ans copper thickness, spray tin full process, to ensure that the size of the current through the good performance.
3. the use of fully enclosed dust potentiometer, more stable performance, more durable than ordinary potentiometer!
4. Specially add the current advanced UPC1237 speaker protection circuit, so that your speakers more secure.
5. subwoofer part by two new TDA7294 composed of BTL output, low-pass filtering is in accordance with the home theater type frequency adjustable design (50-150HZ), strong power! The left and right channels are served by two pieces of TDA7294, the input coupling capacitor using German imports of WIMA 2.2UF coupling capacitors, the sound is sweeter! The board's signal-to-noise ratio is also extremely high, the ear close to the speaker can not hear the AC sound! Is the choice of upgrading 2.1 amplifier!
