Product Name: 2*3000W 1u Class D PRO Digital Amplifier Power Amplifier (DG3.0) Model NO.: DG3.0 Conductive Mode: D Element Number: Push-Pull Amplifier Voltage: 90V-270V Output Number: 2 Sound Channel: 2.1 Function: Post Amplifier Tube Type: Transistor Amplifier Used For: Professional Usage: Hi-Fi, KTV System Type: Professional Amplifier Trademark: VXAUDIO or Your Logo Transport Package: Thick High Quality Carton/Cardboard/Corner Specification: CE, RoHS Origin: China HS Code: 8518400090 Product Description DG3.0FeaturesAdvanced switching mode power supply technology. Full bridge switching power supply topology. Power factor correction technology, power factor up to 0.99, the power range of 90V-270V.Fixed frequency switch mode power level, to achieve high quality of sound accuracy, strong bass, clear and fine treble. Three groups of closed-loop gain loop control, transient. And each channel circuit is independent of each other. HI-FI chip produces unique sound quality.Δ AC protection: When the AC power supply voltage exceeds the operating range, turn off the power supply.Δ Clipper limiter: Prevents severely clipped waveforms from reaching the speaker while still maintaining full peak power output.Δ DC protection: Prevents infrasound signal from reaching the speaker at the output end.Δ Thermal protection:The maximun normal operating temperature of output level and power supply is 75ºC.Δ Temperature controlled continuous variable speed fan, front to back tunnel cooling system.Δ Temperature warning: When the temperature reaches 70ºC, the LCD screen will give warning, the yellow temperature lamp will be on, the output power will be compressed according to the temperature variable, until the overheating warning is removed, so that the power amplifier will not appear after the overheating protection without sound phenomenon.SpecificationModelDG3.0Stereo Power 8Ω2*3000WStereo Power 4Ω2*5500WStereo Power 2Ω2*5500WBTL 8Ω10000WBTL 4Ω11000WFrequency Response20Hz-20KHz (1W@8Ω, ±0.5dB)THD+N<0.5% form 1W to full power (typical value<0.05%)S/N Ratio>110dBA(20Hz-20KHz)Slew Ratio50V/u S @8ΩDamping Factor>5000 @20-200HzCrosstalk>66dB@8Ω 1kHzOperating Voltage90V-270VPower Correction Factorcos>0.95 @ >500Audio Signal Connector4 Female cannons with lockPower LineThe power line fixed on the rear plate of the chassis is 3*2.5m² thick and 1.5m longInput Impedance10KΩ BalancePowerGeneral regulating switch mode power supply with PFCDial Code Control Switch/CHTwo sensitivity switches, one mode switch, one clipper limiter switchHeight1UGross Weight14KGDimensions580*580*116MMProducts DisplayProduction Processabout UsEnping Pusheng Electronic Co, .Ltd is professional of high professional power amplifier and signal processors.
