Pyle PTA1400 1400W Professional Power Amplifier

Two Channels idgeableSpeaker/Terminal Connection,And SPEAK ON. Double Cooling Fan 110/220 Volt Switchable 2x5 LED Input Level Indicator Overload and Protection Indicator Signal/Noise ratio:=102dB Distortion:=1.0% Frequency response:20Hz-20KHz less than±0.5dB input impedance: balance 20KO Input level:+4dB Total Power 1400 Watts.This amplifier works best with either 4-Ohm or 8-Ohm in Stereo application. If the amplifier is bridged in Mono, it is not recommended that it be run below a 4-Ohm load. If running the on lower Ohm impedance speaker, or multiple speakers wired in parallel, it will cause Ohm load issues
