How The HP 500 SE is equipped as standard with two RCA outputs and one XLR output.
How The XLR output is transformer balanced and galvanically isolated
How The HP 500 SE Phono has separate inputs for MM / MC
How Phono MM and MC can be retrofitted.
How Input impedance MC adjustable in wide range
How Soft start for heating, operating voltage and signal output; Thereby maximizing tube life and trouble-free switching on and off. The output is released after 4 minutes.
How The gain of the high-level stage can be switched in two stages
How Stand-by function for bridging multi-hour operating breaks
How External power supply with multiple shielded mains transformer and integrated mains filter
