Page 13: Phono Mm/Mc Option
8. PHONO MM/MC OPTION The role of the phono preamplifier A record player is an electro-mechanical device. Music signals are "pressed" into the grooves in the record, and these are physically tracked and read by the pickup cartridge. In order to get the entire 20 Hz - 20 KHz frequency range into the grooves, the frequency response has to be shaped by lowering the level of the low frequency information and raising the level of the high frequency information. -

Page 18: Troubleshooting
10. TROUBLESHOOTING Noise and hum Hum in an audio system is often caused by several system components being grounded separately. It is particularly common in systems containing tuners, VCRs or satellite receivers connected to an aerial, where a hum loop may be introduced via the aerial input. Although the HP 500 MK3 is also grounded, it is equipped with a special technology that reliably prevents ground loops. -
