CONTROLS AND THEIR FUNCTIONS FRONT PANEL Input Selector: The two position “select input” switch is used to select MM or MC input MC input impedance: The four positions selector switch is used to set input im- pedance (loading impedance) for MC cartridges. The impedance should be select- ed based on cartridge manufacturer’s recommendations. LEFT SIDE OF AMPLIFIER: Power ON/OFF switch: The switch turns the preamplifier ON and OFF EVOLUTION PHONO ONE Solid-state Phono Preamplifier - User Manual... - Page 12 CONTROLS AND THEIR FUNCTIONS REAR PANEL The only control on the rear panel is the line voltage selector switch located next to the AC power inlet (AC INPUT). This switch needs to be set so that the number displayed (115 or 230) corresponds to the line voltage in your country. The rear panel also hosts grounding lug (GND), MM and MC inputs and single-end- ed (unbalanced) line outputs. EVOLUTION PHONO ONE Solid-state Phono Preamplifier - User Manual...
