Langevin was a manufacturer of consoles in the 1960s. Manley Labs has since purchased the name, and although they base some of their solid-state designs on the original Langevin topology, the original units are sonically different. I picked up my discrete two-channel version from a friend, already racked, with phantom power and phase switches. I/O is XLR balanced. Gain is dialed up with a stepped, four-position switch, and there's an output fader knob. No markings indicate gain, but there seems to be about 50 dB or so-using high output mics like the Neumann TLM 103 makes this a non issue. David Marquette (Marquette Audio Labs) has been racking AM16s for several years, and he informed me that the AM16 was originally a stand-alone mic preamp in a tray, similar to the EMI Redd ("Beatles" / V72) consoles, where the console surface had all the controls but the preamps were mounted in the rear of the frame or elsewhere. Apparently, quite a few of the AM16 modules floating around have Capitol (Records) stamped on them. (Any Tape Op readers work at Capitol in the '60s?) The AM16's circuit is similar to a vintage Neve-transformer balanced in and out, with a discrete, Class-A biased circuit doing all the work-but that's where the comparison ends. Sonically, it's beefy and distorted at the top region of its gain settings, working well to toughen up kick and snare drums. I use mine all the time for thickening drum loops. I like to use just two mics when tracking drums, and the AM16 has never failed to impress me, adding a unique presence to percussion, particularly toms and cymbals. Strangely enough, it really did the trick on finger-picked, nylon-string guitar as well, keeping the normally subtle instrument up front in a cluttered mix. David voiced similar thoughts on the AM16's versatility: "It's very open and airy, well balanced in highs, mids and lows. I have clients using it for bass, distorted guitar, OHs, acoustic guitar, vocals, and room mics." (David Marquette can be reached at marquetteaudiolabs.com.)

The use of effect pedals at the mixing board is by no means a new thing. I remember studio owners thinking I was crazy in the '90s when I patched in a SansAmp Bass Driver DI or BOSS DM-2 Delay pedal...
