The Manley Laboratories FORCE is a 4-channel vacuum tube microphone preamplifier based on the award-winning CORE system, and is housed 2RU chassis that is hand-crafted in the USA by Manley Laboratories.

The FORCE is packed with thoughtful design elements such as organized controls, silky smooth and bulletproof rotary potentiometers, and positive latching feature switches and convenient Direct Input 1/4" jacks on each channel. Seven-way LED metering for each channel provides instant visible feedback for audio levels which are enhanced with a double-inlay CNC-milled accent, for a preamplifier unit that is not only a feast for the ears, but a feast for the eyes as well.

A Sonic Tour de FORCE
Your microphone signals enter through gold-plated XLR connectors straight into the 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 megOhm jacks before hitting the input level control which also acts as a Variable Input Pad. Phase Reverse and a 120 Hz High Pass filter can be invoked here in the circuit and then into the 12AX7 dual triode ampliying stage operting in pure Class 'A'. The amount of Gain for each channel can be selected as 40dB to 60dB via the front panel switches, and the output stage is capable of delivering up to a huge +35dBu.

  • Rear-panel XLR microphone input per channel
