Overview

A sonic tour de FORCE.

From America’s premier high-end studio gear manufacturer, the Manley FORCE offers four channels of vacuum tube microphone preamplifiers extracted from the hugely popular and award winning Manley CORE, housed in an exquisitely gorgeous chassis, meticulously hand-crafted, purposefully and efficiently in southern California.

Your relationship with the FORCE begins with the ergonomic facia through its thoughtfully organized controls, silky and bulletproof rotary potentiometers, positive latching feature switches and convenient Direct Input 1/4" jacks.

Seven-way LED metering for each channel provides instant visible feedback for audio levels, which are enhanced with a double-inlay CNC-milled accent. This is investment-grade audio equipment that you will be as proud to showcase in your studio as Manely was to handcraft it in Southern California.

Your microphone signals enter through gold-plated XLR connectors straight into Manley IRON mic input transformers. Your line level sources or instrument level guitars and keyboards come in via the front panel 1/4" Hi-Z 10 Mohm jacks before hitting the input level control which also acts as a Variable Input Pad.
