Behringer PMP 1680S Power Mixer

Behringer PMP 1680S — 1600 W Powered Mixer with Built-In FX and Feedback Control

The Behringer PMP 1680S is a 10-channel powered mixer that folds a 1600 W Class-D amplifier, dual 24-bit effects engines, and FBQ feedback detection into a single 9.9 kg chassis. Built for bands, mobile DJs, houses of worship, and small-venue operators, it replaces a separate console and amp rack with one self-contained unit. Six mono mic/line inputs, two stereo channels, and a CD/Tape return cover vocals, instruments, and playback. This model suits working musicians who want full-range PA performance from a single case.

What Sets This Mixer Apart in the Powered Mixer Tier

Two features separate this unit from entry-level powered mixers. The FBQ Feedback Detection System automatically highlights problem frequencies on the graphic EQ, so a single operator can tame a room in seconds. Dual 24-bit stereo FX processors deliver 100 presets — reverb, chorus, flange, delay, and pitch shifter — assignable to main and monitor mixes, plus a voice canceler for karaoke playback.

Class-D Power Section — Headroom for Mid-Sized Gigs

The amplifier stage earns the unit its 1600 W name. Class-D topology keeps the chassis cool and light while driving passive speaker cabinets with serious output.

• RMS Power @ 4 Ohm: 2x 600 W per channel — drives two full-range tops in stereo with comfortable headroom
• Peak Power @ 4 Ohm: 2x 800 W per channel — transient headroom for kick drums and bass-heavy material
• RMS Power @ 8 Ohm: 2x 300 W per channel — clean stereo output into standard passive cabinets
• Bridged Mono Mode — combines both channels into a single 1600 W mono output for subwoofer or single-cabinet setups

10-Channel Mixer with Dual FX Engines

Eight mic preamps, switchable phantom power, and a per-channel 3-band EQ handle fast tonal shaping on stage.

• Mic Preamps: 8 with switchable +48 V phantom power for condenser mics and active DI boxes
• Channel EQ: 3-band per channel for quick high/mid/low trimming
• Dual FX Engines — two 24-bit stereo processors running 100 presets including reverb, chorus, flange, delay, and pitch shifter, assignable to main and monitor mixes
• Aux Sends: 3 for monitor mixes and external FX routing

Connectivity, Graphic EQ, and Rack-Ready Build

Connectivity targets touring and installed rigs: Speaker Twist outputs, RCA Rec Out for recording, and a 19" rackmount kit in the box.

• Speaker Outputs: Speaker Twist — locking connectors for passive cabinets
• Graphic EQ — stereo 7-band with FBQ feedback detection overlay so problem frequencies light up on the sliders
• Hi-Z Inputs: 6 for direct connection of electric guitars and basses
• Dimensions: 315 x 460 x 220 mm — fits a standard 19" rack with the included mounting kit
• Weight: 9.9 kg — light enough for one-person load-in

Who Should Buy This Powered Mixer

The PMP 1680S is the right choice for solo performers, duos, and small bands playing clubs, weddings, and corporate events who need a self-contained rig in one trip. Mobile DJs benefit from the voice canceler and dual FX engines during karaoke or backing-track sets. Houses of worship get a rackmountable mixer-amp an untrained volunteer can run, thanks to FBQ feedback detection. Schools and rehearsal rooms also fit: 10 channels cover a full band, and the 1600 W bridged output drives a subwoofer.
