Product Details:
This board power amplifier board is suitable for high-fidelity home, stage, professional power amplifiers, high power, clear and beautiful sound quality! In order to achieve the most clear and pure tone, the input is processed by IC, and then through the double differential high-frequency transistor circuit for pre-amplification, the clear and delicate tone of the transistor is implemented to the end, and the tone is even better! The push stage uses two-stage push. First, use the original imported medium-power Toshiba pair tube 2CA1837/2SC4793 to push a pair of TTC5200/TTA1943, and then use this pair of high-power pair tubes to push 11 pairs of TTC5200/TTA1943 parallel output!
The power amplifier board has low distortion, low noise, high withstand voltage, mute switch, over-temperature protection, overload protection, and output short-circuit protection. The components and materials are carefully selected. The circuit design is further perfected. Extremely high sex-to-noise ratio, it is difficult to hear the noise even close to the speaker!
The power supply voltage range of the board is very wide, and it can work reliably between DC dual 50V~110V
Operating voltage: DC ±50~110V (DC ±90V is recommended, and the power supply should be above 1000W.)
The protection circuit needs a separate power supply: DC 15V~25V or AC 12V~18V
Output power: 1500W@8Ω, 2500W@4Ω
Frequency response: +0dB/-0.8dB (20Hz~26KHz)
Total harmonic distortion: <0.3% 8Ω 20Hz~26KHz
Signal-to-noise ratio: (20Hz--25KHz): A-weighted, full power output > 98dB
PCB size: 300*84MM
When bridging at full load for a long time, please use a fan to help dissipate heat. If you work with high power for a long time, you must add a cooling fan
Note: This PCB is mono, if you need stereo, you need to buy two
