INTRODUCTION
GENERAL NOTES
LOCATION & VENTILATION
The Langevin STUDIO HEADPHONE SYSTEM must be installed in a stable location with ample
ventilation. It is recommended, if this unit is shelf mounted, that you allow enough clearance on the
top and bottom of the unit such that a constant flow of air can flow through the ventilation holes.
WATER & MOISTURE
As with any electrical equipment, this equipment should not be used near water or moisture. If liquid
enters the preamplifier, it must be immediately returned to your dealer for servicing.
SERVICING
The user should not attempt to service this unit beyond that described in the owner's manual. Refer
all servicing to Manley Laboratories.
THANK YOU
Congratulations on the purchase of the LANGEVIN STUDIO HEADPHONE SYSTEM. With this
station you will be able to offer musicians a better sounding headphone amp than most major studios
and be able to provide some significant improvements over basic stereo cue boxes or any other
headphone system we know of. We subtitle this unit "THE MORE ME BOX" because this is
possibly its most important feature. Along with the typical cue mix or the control room mix, the
engineer can offer each musician a fader dedicated to their own instrument. Experience teaches us
that each musician always wants to hear more of themselves and that trying to meet this demand with
several musicians and with a few aux sends is quite a mind bending challenge. As long as each
musician's headphone is plugged into a separate station, each can have their own custom mix within
arms reach. This frees up the engineer to concentrate on recording and getting the best sound. It can
free up console aux sends so that they may be used for effect sends. It also tends to allow the producer
to concentrate on perfomances because the musicians monitoring needs are met quickly and easily.
While we strongly suggest that musicians not monitor too loud and possibly damage their hearing,
we know that many musicians will tend to listen to incredibly loud headphones while playing. Most
systems will distort or be gross sounding at these levels causing even more hearing damage, fatigue
and headphone damage than this system will. It is designed to sound good at all levels from quiet
to extremely loud with headphones of all impedances or efficiencies.
