Manufacturer's Description from Manley

Pure . . . Your most important tracks deserve this.

The MANLEY all-tube Dual Mono Microphone Preamplifier is primarily intended for use with modern capacitor (condenser) microphones. Now, 40 to 60 dBs of gain, enough for most ribbon mics, are selectable in precise 5dB steps by varying the amount of overall negative feedback on the GAIN switch. This is a very interesting feature indeed, allowing you to change the slew rate (speed), placement, and tonal balance of the sound from mellow and "tubey-er" through to faster, punchier and more aggressive. See "Notes on Variable Feedback" for more info. 

 

Tube complement per channel: 1 x 12AX7EH hand-selected for lowest noise, and 1 x 6414 for each high-current output stage. Each unit is painstakingly hand wired using silver solder and audiophile-grade componentry. Double shielded custom-built power transformers and custom-built high capacity reservoir capacitors demonstrate our modern power supply design approach. 

 

The front panel 1/4" DIRECT INPUT jack makes these preamplifiers serve double duty as a pure tube line stage for instruments such as bass, drum machines, and keyboards when you need to get your tunes through some tubes before hitting a sterile digital recorder. Total gain in this mode becomes 20dB less than indicated on the GAIN switch. Both transformer coupled balanced and direct (via humongous metalized film MultiCaps) capacitor coupled unbalanced outputs are provided giving you the choice of audiophile-purist or big iron sounds. Perennial shoot-out winners, our single-ended preamp designs have become favorites among top engineers and home recordists alike looking for "that rich Manley sound with the tight bass and the top end that goes on forever" which begs to go direct to tape. 

 

It's a BIG sounding micpre!

About Manufacturer

The MANLEY brand has been around since the late 1980's. Manley's first commercially available products were upper echelon high-fidelity vacuum tube amplifiers and preamplifiers constructed at the old Vacuum Tube Logic of America factory.

In this history lesson, we'd like to direct special focus on our people at Manley Labs. The people whose years of dedication, service, and expertise bring you people, our customers, these products. It's all about the people...

On January 30, 1989, a 20 year old EveAnna on sabbatical from her studies at Columbia University met the crew and was hired on to the production team. Baltazar Hernandez, already with two years experience, taught her how to solder in those first few days. It was in 1989 that the first Manley professional products were developed, starting with the original 1u Reference 60dB Microphone Preamplifier and soon followed by our Manley Enhanced Pultec and Mid Frequency Equalizers. Baltazar and EveAnna, busy building gear, were soon joined by Saulo and Ramiro. Just next door, Elias was employed by a printed circuit board maker later brought into the Manley Labs fold when in 1993, Manley Laboratories, Inc. became a separate entity apart from VTL. The new Manley Labs factory at 13880 Magnolia Ave. in beautiful and bovine Chino, California was outfitted to house the Manley HiFi and Pro Studio manufacturing as well as the Langevin production lines, our newly acquired machine shop, and printed circuit board facilities.

Max. input (with input pad fully open): 450mV

Max. output: +32dBu

Max. output (into 600 Ohm load): (+15dBm)

Power consumption: 36 watts

Operating mains voltage: Units are purpose built for original destination country's mains voltage: 100V, 120V, or 220-240VAC as indicated on the serial number badge. Power transformer must be replaced in order to change mains operating voltage. 120VAC units may NOT be rewired to put the primaries of the power transformer in series for 220-240V operation or a large radiated field of hum will develop. If changing locations/voltages, the power transformer must be replaced with the dedicated one for the voltage at which it will operate.

Mains Voltage Frequency: 50~ 60Hz

Dimensions: 19" x 1 3/4" x 10" (occupies 1u)

Shipping Weight: 12 lbs.
