For over 20 years, this preamplifier has been the epitome for consistent excellence in sound quality and state-of-the-art tube technology.During this time, it has maintained its market-leading position thanks to regular design updates from OCTAVE.\u003c\/p\u003e\n\u003cp\u003eOCTAVE recently developed the SE (Special Edition) version to mark the 25th anniversary of Stereoplay magazine, which first tested the original HP 500 in 1989. The SE brings the HP 500 preamp back to the current state-of-the-art once more. The use of two Siemens D3A (EF 184) pentodes provides the output stage of the HP 500 SE with a significantly greater bandwidth (0.2 Hz to 2.3 MHz, 6 dB).\u003c\/p\u003e\n\u003cp\u003eThe extremely low cut-off frequency is responsible for the clearer and more tightly defined bass, which provides the foundation for a clean low frequency register and a thrilling midrange performance. OCTAVE has also further refined the outboard power supply. MOSFET transistors regulate the high-voltage supply. Increased reservoir capacity, improved rectification with Schottky diodes, and end-to-end electronic stabilization all ensure a virtually noise-free supply voltage with a noise component of less than 300 µV. These measures contribute to the exceptionally high signal-to-noise ratio of 103dB.\u003c\/p\u003e\n\u003ch3\u003eTechnical Data\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain High\u003c\/td\u003e\n\u003ctd\u003e17,5 dB = 7,5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain Low\u003c\/td\u003e\n\u003ctd\u003e9,5 dB = 3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Response\u003c\/td\u003e\n\u003ctd\u003e3 Hz - 500 kHz 1,5 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal Harmonic Distortion\u003c\/td\u003e\n\u003ctd\u003e0.001% @ 3V \/ 7.5 kOhm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal-to-Noise Ratio : Gain High\u003c\/td\u003e\n\u003ctd\u003e- 92 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal-to-Noise Ratio Gain Low\u003c\/td\u003e\n\u003ctd\u003e-103 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLeft\/Right Crosstalk\u003c\/td\u003e\n\u003ctd\u003e65 dB 1 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput to Input Crosstalk\u003c\/td\u003e\n\u003ctd\u003e- 86 dB 10 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e100 kOhm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Impedance\u003c\/td\u003e\n\u003ctd\u003e100 Ohm (Cinch); 2 x 50 Ohm XLR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Balance\u003c\/td\u003e\n\u003ctd\u003e0.5 dB - 70 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003e\n\u003cbr\u003e\u003cstrong\u003ePhono-MM\u003c\/strong\u003e\n\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e47 kOhm || 130 pF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Sensitivity\u003c\/td\u003e\n\u003ctd\u003e3 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRIAA-Equalization Accuracy\u003c\/td\u003e\n\u003ctd\u003e0,3 dB 15 Hz - 20 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain\u003c\/td\u003e\n\u003ctd\u003e40 dB 1 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal-to-Noise Ratio (weighted)\u003c\/td\u003e\n\u003ctd\u003e- 73 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCorner Frequency Subsonic-Filter\u003c\/td\u003e\n\u003ctd\u003e20 Hz \/ - 3 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003e\n\u003cbr\u003e\u003cstrong\u003ePhono-MC\u003c\/strong\u003e\n\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e37-500 Ohm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Sensitivity\u003c\/td\u003e\n\u003ctd\u003e0,1 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain\u003c\/td\u003e\n\u003ctd\u003e30 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal-to-Noise Ratio (weighted)\u003c\/td\u003e\n\u003ctd\u003e- 75 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnections\u003c\/td\u003e\n\u003ctd\u003eInputs : 5 x Cinch, 2 x Phono Option (MM\/MC)\u003cbr\u003eOutputs : 2 x Cinch, 1 x XLR, 1 x Rec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cbr\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003ctd\u003eHT Bypass Option, Sym.
