Since many parts in the unit have special safety related characteristics, always use genuine Hitachis replacemenlparts. Especially critical parts in the power circuit block should not be replaced with other makers.Critical parts are marked with A in the schematic diagram and circuit board diagram.2. Before returning a repaired unit to the customer, the service technician must thoroughly test the unit to ascertain thatit is completely safe to operate without danger of electrical shock.SPECIFICATIONSlnput sensitivity/lmpedance INPUTMaximum outputTotal harmonic distor-tionGainFrequency responseSignal-to-noise ratioEqualizer center fre-quencies1V/38 kohmsVariable range ofadjustmentPower supply voltagePower consumptionDimensionsWeightL, R independent -r 10 dBAC 120V 60Hz, -22OV 50 Hz,-24OV 50 Hz,- 1o0-1 2O|2OO-24OV 50/60 Hz10w435 (W)x 83 (H)x 225 (D)mm3ksTAPE PLAY 1V/38 kohmsOutput level/lmpedance OUTPUT 1Vl4 kohmsTAPE REC 1Vl4 kohms5V (T.H.D.0.1%)O.O2%(2O Hz - 20 kHz ratedoutput)0dB5Hz-30kHz-r1dB96 dB (for rated output, IHF Anetwork)10 elements 31 .5 Hz, 63 Hz,125 Hz,25O H2,500 Hz. 1 kHz.2 kz,4 kHz. 8 kHz. 1 6 kHz* All specifications for this unit apply with a flat equalization.SPECIFICATIONS AND PARTS ARE SU&ECT TO CHANGE FOR IMPROVEMENT.GRAPHIG EfIUALIZERJuly 1982TOYOKAWA WORKSRadioFans.CN 收音机爱 好者资料库HITACHI HGE-I1OOSICH ERH EITSMASSNAHMENTECHNISCHE DATENEingangsempfindlich-keit/lmpedanzAusgangspegel/lmpedanzMax.
