Features:
Size: 18 cm long and 11.5 cm wide.
The voltage used in this version can be from ± 15V to ± 35V. The recommended voltage is ± 24V.
Compared with A100SD, there are the following changes:
1. Two-channel independent servo loops make the two output midpoints consistent, approaching 0mV,
Therefore, in addition to RCA signal amplification, this circuit board can also be used as an XLR balanced signal amplifier board, and one board can be used as a balanced signal amplifier.
2. The output buffer circuit adopts two-stage Walman parallel connection, and the driving ability is more powerful.
The driving ability is increased, the details are more abundant, and the dynamic range is wider. It can also be used as a headphone amplifier board. Changing the output stage resistance can drive various types of headphones.
Note: Do not connect the audio source to DVD, VCD and computer. In that case, you can not take advantage of the characteristics of this board, let alone compare with the entry-level op amp circuit with tone.
