F12 MUSES72320 Enthusiasts Level Preamplifier Board Volume Controller IR Remote Control with 2.08-inch OLED Display
Description:
- This board can be used as a pure volume potentiometer, with a flat output and volume ranging from -100DB to 0DB. It can also be used as preamplifier, with a maximum amplification factor of 20 times and a low output impedance that can be matched with all power amplifiers, such as Class A machines, Class A and Class B machines, electronic tube power amplifiers, etc.
- The MUSES72323 for NJR is currently the best volume control chip in the world. This chip controls the internal adjustable resistor through the SPI interface to adjust the volume. The audio passes through the chip in a fully analog manner, without any digital or VI/IV conversion, and does not affect the sound quality. This chip has advantages such as extremely high DNR and SNR, extremely low THD+N, extremely fine volume adjustment steps, and no built-in operational amplifier (so the sound quality and performance will not be limited by the operational amplifier). The distortion index is much lower than other schemes (such as MAS6116, PGA2310, Alps RK50, Alps RK27, etc.), and should be on par with the R2R resistor/relay network scheme.
Features:
- Using for JRC original MUSES72320 as the core volume and amplifier device, combined with a low noise linear power supply, the sound quality is very excellent, and can be well matched with various rear stages.
- The input adopts 4 out of 1 input, with relay switching and startup delay protection.
- 2.08-inch high-definition OLED display, infrared remote control settings, human-machine dialogue.
- Made from heavy materials such as double-sided gold-plated PCB, Japanese fever capacitor, German WIMA, high-speed rectifier diode, etc.
- Equipped with 6 levels of gain control, it can be matched with different post stage needs.
Specification:
- PCB Size: 118 x 100mm
- Voltage: AC15-20V x 2
Package Included:
- 1 x Preamplifier Board
