Description
The Manley Force 4-Channel Microphone Preamplifier Showcases High Voltage, High Headroom, and High Fidelity – A True Force of Nature
From one of America’s premier high-end studio gear manufacturers, the Manley FORCE contains four channels of real High Voltage vacuum tube microphone preamplifiers extracted from the hugely popular and award winning Manley CORE®, housed in an exquisitely gorgeous chassis, and meticulously hand-crafted in 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. A feast for the eyes. This is investment grade audio equipment that you will be proud to showcase in your studio.
A Sonic Tour De Force
Your microphone signals enter through gold-plated XLR connectors straight into a 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 120 Hz 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 40 dB or 50 dB via the front panel switches. An additional 10 dB of gain is available via internal jumpers. The output stage “can drive a truck”.
A Powerful Force
The MANLEY POWER® power supply is an innovative design developed specifically for Manley Labs, specifically for High Voltage vacuum tubes, and specifically for audio by the world expert team in this technology led by Bruno Putzeys. Proven reliable and sonically superior in the Manley CORE®, this power supply provides 300 Volt DC rails to run the vacuum tubes, beefy 6 Volt lines to power them up, along with several other voltage rails for the phantom power and various solid-state control voltages. High Voltage = High Headroom, folks. Manley proclaims with confidence that you will not get near this sonic performance with in any 500-series design. This is Full FORCE audio excellence which starts with this superior power supply. All lines are importantly regulated, low impedance, efficient, and super-quiet in this low radiating high frequency design. The universal mains input accepts any voltage or frequency from anywhere in the world making travel with the FORCE a breeze.
