Power Amplifier PS-4800

Main Feature 1. Fashion front panel is made of aluminums alloy with metal wiredrawing craft surface treatment; 2. Sturdy steel case can shield the electromagnetic interference from outside; 3. Strong multi-protection mechanism including radiating protection, short, circuit protection, switch delay protection; 4. 4 channels output and 800W rated power of per channel can achieve driving bass, mellow alto and clear treble; 5. Multistage power transmission combines H technology and topology will led to clear and driving sound, and reduces electric consumption; 6. Design of optimized switching power supply makes the amplifier smaller and easy to be installed; 7. High quality connectors guarantee perfectly signal transmission by firming conjunction; 8. It's suitable for large stage performances, pubs, KTV rooms and conference halls etc. Technical Specifications 8O stereo(per channel) (1kHz(EIA)with 0.5%THD):4*800W 4O stereo(per channel) (1kHz(EIA)with 0.5%THD):4*1100W Frequency Response ref 1k: THD+N:20Hz-20kHz,+0/-1dB < 0.5%,20Hz-20kHz Voltage Gain: 38.3dB Intermodulation Distortion(IMD): ?0.35% Slew Rate: >10V/us Damping Factor (8 O), 10Hz-400Hz >200 Signal-to-Noise Ratio (20Hz -20kHz): >100dB Crosstalk (1 kHz, 20 kHz): -75dB -59dB Input Sensitivity for full rated power at 8O: 0.775V or 1.4V Input Impedance (nominal) Balanced / Unbalanced: 20kO / 10kO Input Connectors: Once balanced XLR per channel Output Connectors(Speaker Connectors): 4-POLE Speakon per channel Front Panel Controls: Power on/off switch, one gain control per channel Rear Panel Controls: Power on/off switch ,one gain control per channel Input sensitivity switch:0.775V or 1.4V Power Indicator Signal Indicator: One red LED of work, One green LED per channel Clip(peak) Indicator Fault Indicator: One yellow LED per channel, One red LED per channel Protection: Protection against short circuits, no-load, on/off muting, Rf interference.
