      All,

      I have designed a stereo RCA (single-ended) to XLR (balanced) converter.

      I will have both fully assembled and bare boards available.
      Fully Assembled boards: 150 to 180 USD + shipping depending on interest
      Bare boards: 12 to 18 USD + shipping depending on interest, see BOM in attachments.

      Parts used are OPA1622 as initial buffer to OPA1632 for SE to balanced conversion.

      Input impedance (RCA): 47kΩ
      Output impedance (XLR): 100Ω
      Gain: 8dB
      Input Power Voltage: 9V on Barrel Plug (2.1mm I.D. x 5.5mm O.D. x 9.5mm)
      Max Output Voltage: 7.07 Vrms (19.2dBU)
      Max Output Current: 70 mArms

      Can be ordered at link below, with 20% off, coupon code is “rcaxlr“. Delivery in June/July.
