HifiSonix Standard PSU PCB
in Power supplies, Preamplifiers
This PSU features +-18V rails, <100 uV wideband noise at full load along with a muting control circuit for any muting function required by the end user. Additionally, a +12V 40mA relay supply is provided and +5V/+3.3V at 60mA. The board uses a low noise 15 or 25VA PCB mount Nuova Talema transformer.
Hifisonix High Performance Balanced Line Stage PCB
in Preamplifiers
This line stage employs OPA1641 and OPA1642 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 […]
