From the Core, the Manley Labs Force incorporates the same proprietary hand-wound Manley Iron mic input transformers and 12AX7 vacuum tube amplifying stage operating from 300 V rails. Each channel includes a high-impedance, ¼" instrument input as well as an XLR microphone input. On the front, each channel features a 120 Hz high-pass filter, variable input-level pad, phase invert, selectable +48V phantom power, and a high/low gain switch. The CNC machined faceplate features seven-way LED metering for each channel providing instant visible feedback for audio levels. The universal power supply accepts any voltage or frequency from anywhere in the world facilitating travel for international recording projects. As with all Manley gear, each unit is painstakingly hand-wired using silver solder and audiophile-grade components, and hand-built in California.
