Killer Mic Pre. Times Four.

The Manley Force Quad Mic Preamp uses a topology based on Manley’s CORE mic pre section, delivering the same musical character and performance across four channels. It features the same input level control and switch arrangement as the CORE, along with Manley’s mic input transformer and a 12AX7 vacuum tube gain stage. The primary technical distinction is the inclusion of Manley’s MOSFET White Follower design, paired with the Entrodev switched-mode power supply, resulting in a powerful, modern four-channel mic preamp built for professional studio environments.

What Manley Says...

The Manley Force® — Four Channels of Pure Class-A Tube Gain

  • Four channels of high-voltage tube microphone gain
  • All-tube, Class-A design with 12AX7 dual triodes
  • High-headroom architecture with custom hand-wound Manley IRON® input transformers
  • Manley Power® supply with punchy front-panel DI instrument inputs
  • Hand-assembled in California

The Manley Force delivers four channels of all-tube microphone gain derived directly from the award-winning Manley CORE® channel strip. Each channel features a 12AX7 dual triode vacuum tube paired with a custom hand-wound Manley IRON® input transformer, delivering the clarity, depth, and harmonic richness Manley is known for. Designed around the principle that high voltage equals high headroom and high fidelity, the Force provides a transparent yet authoritative front end for professional recording.

At the heart of the Force is its all-tube, Class-A signal path, optimized for both microphones and DI instruments. Dedicated front-panel Hi-Z inputs allow guitars, basses, and keyboards to feed directly into the tube gain stage, adding musical weight and responsiveness that plugins alone can’t replicate. Intuitive controls include switchable 40dB or 50dB gain, phase reverse, a 120Hz high-pass filter, and a continuously variable input attenuator for precise gain staging. Clear seven-segment LED metering and positive-action switches ensure fast, confident operation in demanding studio sessions.
