Module unbalanced to balanced symetrizer JRC 4580DD BTL stereo

This audio module balances any HIFI-RCA-CINCH line-level asymmetric signal into a balanced-XLR signal independently and qualitatively. Equipped with quality passive components, the asymmetric input signal is processed by an JRC 4580DD per side on DIP 8 support. It is possible to replace the original PDOs with other models DIP 8 with pinout JRC 4580DD (eg OP2134 or NE5532).

This card is easily "tweakable" especially to replace the original capacitors by higher quality models. (Blue filter capacitors from 2200μF to 35V and yellow capacitors from 2.0μF)

It is suitable for the following assemblies and figures:

• Audio sources on CINCH-RCA analog output (CD players, BluRay, DAC) to studio and sound devices, eg mixing tables with balanced inputs.
• Home theater or HIFI preamplifier with RCA outputs to professional amplifiers with balanced XLR inputs.
• HIFI preamplifier with RCA outputs to HIFI High-End Audio amplifier high-end XLR balanced.
