Product description:The TAS5630D amplifier board can provide 2.1-channel output power of 300W+150W+150W under a DC48V, 4 ohm load. High-definition media playback and ultra-low distortion in Blu-ray home theater systems, stand-alone home theaters, and professional audio systems. Is the current top digital amplifier This is a flagship digital amplifier. Its analytical power and details are all extreme. Its driving force is very powerful and its power consumption is very low. This board is a finished board that can be used when powered. Maximum Power Per Channel: Above 200W Model Number: TAS5630 Channels: 3 (2.1) Package: Yes Color: yellow Material: metal + pc Parametric indicator: (subwoofer channel) DC=50V, R=4, +N=10%, P=300W DC=50V, R=6, +N=10%, P=210W DC=50V, R=8, +N=10%, P=160W DC=50V, R=4, P=240W when +N=1% DC=50V, R=6, +N=1%, P=160W DC=50V, R=8, when +N=1%, P=125W Total Harmonic Distortion (+N): less than 1% Signal to Noise Ratio (): 100dB Input impedance: 20K Output offset voltage: less than 150mV Voltage gain: adjustable Conversion Rate (): 50V/us Frequency Response Range: 20Hz--20kHz PCB size: 140 * 102MM Power supply range: DC20--50V (minimum 24V 8A and above) Features: The op amp is used as the left and right channel preamplifiers, with excellent dynamic and detail performance. Note: The board is a DC power supply. Do not input AC directly. Use an AC transformer, externally connect a rectifier bridge and filter capacitor. In addition, the DC power supply should not exceed 50V and it should not be lower than 20V. If it is less than 20V, it will not start. In addition, there is a relationship between the output power and the power of the power supply. The 50V power will be4 times larger than the power at 20V. Package included: 1 * audio high power digital amplifier board Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
