- Page 5 The phono amplifier stage carries an array of slide switches that enable optimal matching to phono cartridges of various output voltages and load requirements. Selection of CA2 inputs is achieved via a five position rotary control using gold plated relays for silent switching. Output volume adjustment is achieved through a precision motorized potentiometer.
- Page 6 P r e a m p l i f i e r The phono amplifier can be configured to accommodate a wide selection of phono cartridge types by setting combinations of the board mounted jumpers (links). Access to the phono stage is gained by removing the cover of the preamplifier.
- Page 7 Once connected to mains power and powered up from the rear panel mains switch, the front panel Standby button (or remote handset Standby button) will switch the CA2 between standby and active mode. In Standby mode the Standby Indicator glows RED. Operating the Standby function from either the front panel or the remote handset will switch the CA2 into active mode.
