Manley FORCE Four Channel Vacuum Tube Microphone Preamplifier
Description
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.
Phase Reverse and a 120Hz High Pass filter can be invoked here in the circuit and then into the 12AX7 dual triode amplifying stage operating in pure Class A, of course. The amount of GAIN for each channel can be selected as 40dB to 60dB via the front panel switches. The output stage "can drive a truck" as we like to brag delivering up to +35dBu.
You will not get near this sonic performance with any 500-series design. This is full FORCE audio excellence from Manley Labs, proudly built by an American workforce.
