Manley Force Four Channel Mic Preamplifier

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. A feast for the eyes, yeah, we know. This is investment grade audio equipment that you will be as proud to showcase in your studio as we are to handcraft it here in Southern California.

Your microphone signals enter through gold-plated XLR connectors straight into our MANLEY IRON® Mic input transformer. Your line level 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 120Hz High Pass filters can be invoked here in the circuit and then we're 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 or 50dB via the front panel switches. An additional 10dB of gain is available via internal jumpers. The output stage "can drive a truck" as we like to brag.
