Note: The default is a kit. all the parts need yourself to solder it. if you need assembeld board, price need extra 3USD
welcome combine shipping for Multiple purchases!!!
Double-sided PCB Size: 121x86mm
Load current capability: 50-500ma adjustable (With high output voltage, no high current input is used to avoid large thermal power consumption)
Input voltage: Dual AC 20V to 55V
Output voltage: +-DC15v to +-DC60v
Features: low internal resistance, high precision, TL431 for precision pressure. Can be used to polish the DAC decoding, the preamplifier and the power amplifier's voltage amplification stage, the actual listening low frequency is rich, the high frequency is delicate, the effect is very good, for the low frequency thin, high-pitched and dry machine, after using this board, it will get better. Improve the effect, and the debugging is very simple, the component can be successfully created without wrong insertion.
Debug parameters:
Add 2 DIP switches, one for each positive and negative power supply, which can adjust the input current. Generally, the input current is low at low voltage, such as amp, class A preamplifier. Use small input current under high voltage, such as power amplifier voltage. level.
The larger the input current, the higher the output voltage and the higher the heat dissipation temperature, so the setting of the input current is very important.
The sense of hearing is not as big as possible. For example, a circuit only needs 10MA current. If you set it to 300MA, it will sound a bit rigid.
