The Behringer PMP powered mixers produce even more power than their predecessors while maintaining a famously low weight and high efficiency. These mixers employ Class-D technology including a new switch-mode power supply, significantly reducing weight and heat. The 16-channel PMP4000 features 8 high-quality built-in mic preamps and 24-bit FX processors and FBQ Feedback Detection.Instead of operating relatively continuously like Class AB circuits, Class-D amps switch on and off thousands of times per second delivering power only when needed. This significantly reduces power losses from the output devices given off as heat, which means the amps don't need massive heat sinks, and that makes them lighter and have no need for lengthy rest cycles. When used in conjunction with switching-mode power supplies, which don't require huge and heavy transformers, these Class-D amplifiers provide tremendous dynamic punch and superior fidelity. The resulting speaker systems are much lighter and easier to transport and set up.This model gives you the choice of 2 x 800W stereo, 2 x 800W dual mono mode (giving you a mono version of the main signal through one powered output plus a mono version of all monitor send signals through the second powered input) or 1,600W bridged mono sound. Whether the center of attention happens to be a folk trio, a speech, or a synth-rock band with mind-boggling stereo patches, PMP mixers can accommodate. This sonic versatility also makes it an excellent choice for churches, where vocals and stereo recordings often share face time.Leave the mic preamps at home, because the quality of sound that was once only available in the studio is ready to go wherever you do. The PMP4000 gives you 8 inputs with built-in, boutique-caliber mic preamps with switchable +48V phantom power, making it possible to use either dynamic or condenser mics, as well as guitars or other mono instruments. Stereo channels 9-16 are designed to work in pairs as stereo channels, or independently for more mono instruments. All mono channels have 3-band EQ, switchable Low cut filter, and Clip LEDs to indicate when the input signal is too hot.The new generation of PMP mixers come equipped with 24-bit FX processors, giving you 100 mind-blowing digital effect presets such as delay, chorus and reverb. Apply them to any channel, as well as to the monitors and main output. In case you're pulling double duty as sound engineer and performer, the FX processors feature a footswitch jack for remote on/off. Of course, if you have treasured outboard gear you've grown attached to, these mixers can integrate them into the mix while leaving out the built-in FX processor.Medium-sized events call for a lightweight (28.9 lbs), easy-to-use powered mixer. Behringer powered mixers are the most efficient, affordable mixers for the job, and are even suitable for use as pure analog mixers or as pure power amplifiers. With new technological advantages and incredible built-in features, it's easier than ever to lend exceptional sound quality to all kinds of public performances.FeaturesRevolutionary Class-D amplifier technology: enormous power, incredible sonic performance and super-light weightUltra-compact design at nearly half the weight of conventional powered mixers16-channel mixer section features 8 mono and 4 stereo channels plus separate CD/Tape input/outputStudio-grade 24-bit stereo FX processor with 100 awesome presets including reverb, chorus, flanger, delay, pitch shifter and various multi-effectsRevolutionary FBQ Feedback Detection system instantly reveals critical frequencies for easy feedback removal8 high-quality XENYX Mic Preamps with switchable +48V phantom power for condenser microphonesEffective, extremely musical 3-band EQ, switchable low cut filter, and clip LEDs on all mono channelsStereo 7-band graphic EQ allows precise frequency correction of monitor or main outputsVoice Canceller function removes singer's voice from recordings for karaoke applicationsSelectable stereo (main L/R), double mono (main/monitor) or bridged mono amplifier operation modeBreathtaking XPQ 3D stereo surround effect for more vitality and enhanced stereo imageAdjustable stereo CD/Tape input for connecting external signal sourcesMulti-functional stereo Preamp outputs for added flexibilityInternal switch-mode power supply, noise-free audio, superior transient response and very low power consumptionSpecificationsInputs:Microphone Inputs: XLR, electronically balanced input circuitMono Line Inputs: 1/4" TS connectors, balancedStereo Line Inputs: 1/4" TRS connectors, unbalanced2-Track Input: RCAOutputs:Preamp Outputs (Main): 1/4" TRS connectors, unbalancedMonitor Outputs: 1/4" TRS connectors, unbalancedStereo Outputs: 1/4" TRS connectors, unbalancedLoudspeaker Outputs: Professional locking connector (Speakon)DSP Converter: 24-bit Delta-Sigma, 64/128-times oversamplingOutput Power:RMS @ 1% THD, both channels driven:8 Ω per channel: 300 W4 Ω per channel: 600 .
