Selection




As key components are of transistors and ICs, the power consumption is remarkably reduced and the system is by far small in size and weight. Unless the load becomes excessive, no speaker matching is required by adopting the regulated voltage system for output circuit. The system incorporates the AC/DC automatic switching circuit. Therefore the system can continue the operation even when AC power failure occurres. The system is designed to cope with varied specification of controlling circuit etc.

  • Source of Power: AC 220V, 1?, 50/60 Hz & DC 24V
  • Audio frequency Amplifier Output : 100W~800W
  • Frequency characteristics : 300~8000Hz within 6dB
  • Distortion : less than 5% (with rated output)
  • S/N ratio : more than 50dB
  • Built in Equipment
  • Receiving system : Super-heterodyne system
  • Receiving frequency : AM 530 ~ 1605 KHz : FM 88 ~ 108 MHz
  • Receiving sensitivity : AM less than 15㎶, FM less than 10㎶
  • Image ratio : more than 15㎶
  • Selectivity : less than 5 KHz for -6dB : less than 16 KHz for -40dB
  • Intermediate frequency : 455 KHz
