V162 600W+600W Amplifier Board Two Channel Power Amp Board Suitable for Professional Stage Uses
Features:
- V162 dual-channel high-power amplifier board.
- Enabling Hifi sound quality.
- 600W+600W: 16pcs imported transistors 1943 and 5200.
- Due to its powerful and clear sound quality, it is suitable for hifi home, stage performance and professional amplifier machines.
- Dual differential circuit is used for pre-amplification, and the timbre is clear and delicate. The push stage uses three stages to push. After the input differential amplification, push the medium power transistors, and then push TTC5200/TTA1943 as power output. The amplifier board is 2-channel. Each channel adopts 4 pairs of new imported transistors, TTC5200/TTA1943 in parallel for output. 2 channels with a total of 16 transistors in parallel for outputs. The design can improve the use effect, full of thrust.
- Original transistors are used to ensure that the withstand voltage is strong enough and the use effect is impressive.
- Optimized circuit design: integrated switch mute, over-temperature and overload protection. The overall noise ratio is high
- Power supply voltage range: dual DC 55V-100V (The recommended working voltage is dual DC about 60V. It is recommended to use a transformer above 400W. Use dual AC 40-70V, add a rectifier filter plate and then use it. If you want to fully exert the energy of the amplifier board, you need to use a transformer above 1000W).
- The protection circuit needs a separate power supply (AC 12-18V must use a separate winding, cannot be shared with others).
Attention:
- When working at high power, please add a fan to enhance heat dissipation.
- The main voltage of the power amplifier board is DC power supply, and users should add a rectified power board.
