Manley Labs Force 4-Channel Microphone Preamp

Four-channel, high voltage vacuum tube microphone preamplifier
MFR# MFRC

Product Description

The Manley Labs Force 4-Channel Microphone Preamp features ergonomic facia with 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.

The microphone signals enter through gold-plated XLR connectors straight into the 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 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. You will not get near this sonic performance with in any 500-series design. Trust us. 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.

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
