PS-2800 2U class H SMPS professional power amplifier (2×800W at 8 honm)
MAIN FEATURE1. Fashion front panel is made of brushed aluminums alloy;2. Sturdy steel case can shield the electromagnetic interference from outside; 3. Strong multi-protection mechanism including radiating protection, short circuit protection and switch delay protection;4. Powerful output capacity to 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 performance, pubs, KTV rooms and large conference rooms etc. TECHNICAL SPECIFICATIONS8Ω stereo(per channel) (1kHz(EIA)with 0.5%THD): 2*800W4Ω stereo(per channel) (1kHz(EIA)with 0.5%THD): 2*1200W8Ωbridge mono (1kHz(EIA)with 0.5%THD): 2400WVoltage Gain: 35dBTotal Harmonic Distortion(THD): 10V/usFrequency Response (at 1 Watt): 20Hz-20kHz,+0/-1dBDamping Factor (8 Ω), 10Hz-400Hz >200Signal-to-Noise Ratio (below rated power,20Hz -20kHz, A-weighted ): >100dBCrosstalk (below rated power) At 1 kHz At 20 kHz: -75dB -59dBInput Sensitivity for full rated power at 8Ω: 0.775V or 1.4VInput Impedance (nominal) Balanced / Unbalanced: 20kΩ / 10kΩInput Connectors: Once balanced XLR per channelOutput Connectors(Speaker Connectors): 4-POLE Speakon per channelFront Panel Controls: Power on/off switch, one gain control per channelRear Panel Controls: Power on/off switch ,one gain control per channel Input sensitivity switch:0.775V or 1.4VPower Indicator Signal Indicator: One red LED of work, One green LED per channelClip(peak) Indicator Fault Indicator: One yellow LED per channel, One red LED per channelProtection: Protection against short circuits, no-load, on/off muting, Rf interference.
