Description & Details
Summary
- This circuit uses three TI NE5532 operational amplifiers, with one stage for gain, one stage for buffering, and one stage for equalization processing.
- It is equipped with a mute circuit for power on/off, which basically eliminates impact noise during power up and down.
- Reverse connection protection for positive and negative power supply poles is provided.
- It features wide voltage regulation and can operate within DC9-29V.
- A built-in boost module can convert a single power supply into a ±14.5V dual power supply to power the circuit, offering a large sound dynamic range and strong driving force, capable of driving high-power rear stages. The output is designed with two impedance interfaces for easy connection to different power amplifiers.
Preamplifier Tone Board Speaker MP3 Audio Modification Amplifier Board Control Panel DC9-29V Power Supply Description
This circuit uses three TI NE5532 operational amplifiers, with one stage for gain, one stage for buffering, and one stage for equalization processing.
It is equipped with a mute circuit for power /off, which basically eliminates impact noise during and down.
Reverse connection protection for positive and negative power supply poles is provided.
It features wide voltage regulation and can operate within DC9-29V.
A built-in boost module can convert a single power supply into a 14.5V dual power supply to power the circuit, offering a large sound dynamic range and strong driving force, capable of driving high-power rear stages. The output is designed with two impedance interfaces for easy connection to different power amplifiers.
The low-impedance interface can be connected to pure rear-stage power amplifiers.
The high-impedance interface can be directly connected in parallel to the input terminals of combined power amplifiers with preamps or other audio devices.
