LG-139 JRC5532 Balanced XLR To Single Ended RCA Output Double OP Amp Circuit

Description: Introduction: The distortion and noise of this circuit are much lower than that of ordinary circuits, so the circuit looks not so simple, a little more complicated, and the purpose is low distortion and low noise. Using double balanced stages, two differential amplifier stages receive balanced input signals at the same time, and also improve the circuit common-mode rejection ratio (CMRR). The thermal noise of the resistor is greatly reduced, and finally, the noise is reduced by -112dBu, which is 8dB better than the traditional single difference amplifier circuit. FR4 double-sided glass fiber PCB, the arc wiring is grounded at one point. Imported high-quality RC components are assembled. Japan KOA 1/4W high-precision five-color ring metal film resistors, nichicon and ELNA electrolytic capacitors, gold-plated IC sockets (convenient for you to upgrade the op amp yourself), JRC5532 dual op amp. The scope of application is very wide: It is small in size and can be installed inside any preamplifier/power amplifier, XLR balanced signal input to single-ended RCA output. You can easily connect to your preamplifier board or power amplifier board. Op amp upgrade model reference: You can DIY upgrade these op amps to improve the sound quality, such as: AD826, AD827, OPA2134, OPA2604, OPA2111 and other high-end op amps, the effect is immediate after replacement. Parameter: Input voltage: DC +/- 12---18V Op amp model: JRC5532 PCB Size: 82mm*39mm (L*W) Channel: Mono (If you want to create a stereo, you need to buy 2 PCS) NOTE: We have DIY kit or Finished board (Optional) ◆ DIY kit ---- All parts need you to solder and test it. ◆ Finished board ---- All parts have been welded and tested OK.
