Referring to some application circuits of Marantz&x27;s HDAM, we designed this IV module by combining the open-loop IV current transmission module we designed.
Current input, zero point (midpoint) automatic servo, input and output without capacitance
In order to verify the effect of HDAM SA, SA2, SA3, we have made samples respectively. It is best to choose HDAM SA. This module has the most open sound and the best sound elasticity.
Features of sound:
Compared with the op amp or negative feedback type, the sound field is much larger, the details are clear, the low frequency elasticity is prominent, and the layers are clear, especially suitable for the performance of large dynamic and large-scale music.
The following are SA2 SA3 modules, all designed according to the official drawing parameters of Marantz
The following are the SA modules we use, all designed according to the official drawing parameters of Marantz

Ming Charm2 installation method:
Pick up a few resistors and capacitors
Use Note:
1. Be sure to power off the operation, otherwise it may damage the TDA1541 chip
2. The signal pin and the power supply polarity must not be wrong
3. 1541 current output pins are 6 pins (R) 25 pins (L), 5 pins are analog ground, when refitting, you need to disconnect the output 2 pins from other circuits
4. Because it is an open-loop circuit design, it is inevitable that there may be some background noise. If you mind, please take pictures with caution
5. This module will be refunded within 7 days. If your system performance is not satisfactory, please contact the store manager
6. This module is a zero-point dynamic servo adjustment, there will be popping sound at the moment of booting, please pay attention to the boot sequence, first turn on the CD, then turn on the decoding, then turn on the preamp, turn the volume of the preamp to the minimum, then turn on the power amplifier, and turn off the power amplifier first.
