Product Details


The TDA7294 is a famous European SGS-THOMSON STMicroelectronics destroy in the 1990s out of a field pipe the output of high-power IC. Quite bile taste. Completely changed the integrated amplifier raw, cold, hard tone, and is widely used in the field of HI-FI. The chip is designed to tone focus with a high voltage, low noise, low distortion sound soft Naiting.

Product Details

1. This board uses 1.6 mm dual-panel design, 2.0-oz copper thickness, HAL whole process to ensure good by the size of the current performance. Taiwan imports of the metal film 1% tolerance precision resistor, small capacitors original capacitor, coupled with genuine the German WIMA2.2 micro method fever capacitance, and filter 10000 microfarads capacitance, rectifier 25A flat bridge, to ensure strong resistance is a steady stream of power to support.

2. The biggest characteristic of this board is to use the advanced C1237 BTL speaker protection circuit can be realized on, shutdown, mute and speaker protection function.

3. The product integration rectifier, power amplifier, speaker protection, simple installation, convenient

4. The board material stress, rational circuit design, high-noise ratio, the sound quality is pure and sweet, details of outstanding performance is a highly cost-Hi-Fi amplifier.

5. Output power: 150W +150 W

6. Output Impedance: 8 ohms

7. Recommended power supply: 24V-0-24VAC ~ 26V-0-26VAC (150W or more better)

8. Board Dimensions: length 148mm × width 77mm x height 50mm

9. Note: This amplifier board output power, install a large enough radiator! IC metal parts of the negatively charged and canâ
