The compact PLX1804 brings the same performance and technology as the rest of the PLX2 Series, plus even greater value, to applications that don't require bridged or 2 ohm operation.

Designed to power one or two speakers from each amplifier channel (4 ohm minimum loading), this model offer a simplified feature set while retaining genuine, uncompromised PLX performance and technology. Weighing just 13 pounds (5.9 kg), the "plug-and-play" PLX1804 is perfect for ultra-portable rigs, as well as reference-quality playback.SPECIFICATIONS:Stereo Mode8 ohms (each channel) *:• FTC 20 Hz - 20 kHz 0.05% THD: 550W• EIA 1 kHz 0.1% THD: 600 WStereo Mode4 ohms (each channel) *:• FTC 20 Hz - 20 kHz 0.05% THD: 800 W• EIA 1 kHz 0.1% THD: 900 W• Signal to Noise (20 Hz - 20 kHz): -106 dB• Input Sensitivity @ 8 ohms: 1.20 Vrms• Gain @ 8 ohms: 35 dB• Output Circuitry: 2-Step Class H• Distortion (SMPTE-IM): Less than 0.02%• Typical Distortion 1/8 rated power, 20 Hz-20 kHz: Less than 0.02% Full rated power, 20 Hz-20 kHz: Less than 0.02%• Frequency Response: 20 Hz-20 kHz, -0.5 dB• Damping Factor: Greater than 200• Input Impedance:20k ohms balanced10k ohms unbalanced• Input Clipping: 5.5 Vrms (+15 dBu)• Cooling: Variable-speed fan, rear-to-front air flow• Input Connectors, each channel: 3-pin XLR and 1/4" TRS balanced• Output Connectors, each channel: Neutrik NL4 Speakon(Both channels available on Ch 1 output)• Rear Panel Switches: Circuit Breaker• Front Panel Controls:Detented Input Attenuator: 0 to 8 dBPower On/OffFront Panel Indicators:Clip: Red LED -10: Green LEDSignal (-35 dB): Green LEDPower: Blue LEDPROTECTION• Amplifier Protection: Full short circuit, open circuit, thermal, infrasonic, ultrasonic, and RF protection.
