Stereo Balanced Line Stage PCB

Description

This high-performance line stage employs OPA1641 and OPA1642 low noise JFET input opamps to provide a left + right balanced output plus two unbalanced outputs per channel.  All outputs are equipped with relay muting (the mute control can come off either the Hifisonix Standard PSU or the X-Altra Mini II Remote Control Board).  For specifications, BOM and write-up, see the X-Altra Mini II main presentation. Total current consumption c. 50mA with all relays engaged.
