1500w 14 Pairs, 5200 and 1943 power amplifier with speaker protection and temperature protection.
Availability: In Stock
Mono professional high-power fever professional high-fidelity 1500W power amplifier finished board
High-quality circuit + high-quality components
Pieces + high-quality craftsmanship = high-quality products
This power amplifier board is designed independently for single channel, two channels need to be used for group two channels, and multiple channels need to be used for group multi-channel
The circuit design is full high frequency transistor, the circuit design is reasonable, the materials used are exquisite, the tone is quite clear and delicate, and the sound field is quite full. The sound is powerful and dynamic.
High voltage, high current, high dynamic
The wiring diagram of the power amplifier board is as follows:
The output voltage of the transformer is rectified
The filtered voltage. Dear friends, don't make a mistake
Note: The power supply of the protection circuit must be used independently, not shared with other boards
28 Toshiba tube 1500W power amplifier board has a relatively wide power supply range
The main voltage is recommended to be between +/-40V and +/-90V
DC dual voltage
The power supply of the protection circuit is recommended to use about 12V to 18V (1A)
AC single voltage
(If you need to use DC power supply, please contact customer service how to connect)
The size of the power amplifier board is as follows
In order to pursue a clear and pure tone, this board specially uses high-frequency transistor circuit design to make the transistor clear
The delicate tone is carried through to the end,
Push tube use 2 pairs
A1943/C5200 pair tube
Enter the use name IC 5532 or 2068
The power output stage adopts 12 pairs of Toshiba's audio dedicated pair tubes A1943/C5200 in parallel for output
This board uses genuine original imported matching tubes, otherwise it is not resistant to high pressure and guarantees the effect.
This power amplifier board has low distortion, low noise, high withstand voltage and mute switch on and off. It has perfect over-voltage protection, over-temperature protection, overload protection, output short-circuit protection. The sound is pure and beautiful, and the component materials are unmatched. The circuit design is relatively complete. Very high SNR, it’s hard to hear the noise even if it’s close to the speaker
