Power amplifier

(1) There are two ways of input: balanced input and unbalanced inputand three modes can be chose: Stereo, MONO, bridgeable. (2) With a delay circuit for relay, it can protect the speaker system, and adjust the shock wave when the produce is start-up.(3) With dependable multiple protection: overload, over temperature, short circuit and delay of start-up. (4) Using low noise temperature control fan, if the temperature is exceed the safe setting, this unit will shut down automatically until the temperature is back to normal. (5) With high precision longevity potentiometer, it can control the output power accurately. (6) With high efficiency capacitor for power filter, the capacitor and nonpolar capacitor are import from U.S.A. (7) With Japanese high quality big power audio tube with Toshiba. (8) The design of the frame in this produce can avoid all the mechanical interfere and electrical interfere.specifications: ModelPV-1800Output power(4Ω)1200W+1200WBrigae output power(4Ω)2000WT.H.D0.16%Frequency Response20Hz 20KHz+2dBSNR-93dBSeparation70dBInput sensitivity0dBu(775MV)Attenuation80dBInput Impedances20K Balanced10K UnbalancedProtectionhight temperaure,DC,Peak current Limiters,short, Start-updelay Cooling2-stage fans,front-to-rearPower supply 220V 50HzDimension(WxHxD)482x145x475mmNet weight25.6Kg ModelPV-1200Output power(4Ω)720W+720WBrigae output power(4Ω)1500WT.H.D0.16%Frequency Response20Hz 20KHz+2dBSNR-93dBSeparation70dBInput sensitivity0dBu(775MV)Attenuation80dBInput Impedances20K Balanced10K UnbalancedProtectionhight temperaure,DC,Peak current Limiters,short, Start-updelay Cooling2-stage fans,front-to-rearPower supply 220V 50HzDimension(WxHxD)482x145x475mmNet weight22Kg ModelPV-1000Output power(4Ω)620W+620WBrigae output power(4Ω)1000WT.H.D0.16%Frequency Response20Hz 20KHz+2dBSNR-93dBSeparation70dBInput sensitivity0dBu(775MV)Attenuation80dBInput Impedances20K Balanced10K UnbalancedProtectionhight temperaure,DC,Peak current Limiters,short, Start-updelay Cooling2-stage fans,front-to-rearPower supply 220V 50HzDimension(WxHxD)482x145x475mmNet Weight21Kg
