INTRODUCTION!3THANK YOU!...for choosing the Manley Laboratories Microphone Preamplifier. We use this manual for both theMONO and DUAL MONO versions. They are identical except the DUAL has two of everything.These are all-tube Microphone Preamplifiers chock full of nice audiophile parts that combine flatfrequency response, very high headroom, low noise, and low distortion with a big rich beefy sound.We wind the input and output transformers right here at Manley Labs. The Input Attenuator iscleverly before the tube stage so that it can easily accomodate any reasonable signal level andfunction like a variable pad. There is also a rotary GAIN switch which changes the amount ofnegative feedback changing thepreamplifier's operating characteristics, slew rate and speed, (as wellas the gain) to suit a wide variety of tastes and styles. The direct inputs are favourite features of thesedesigns. There are both balanced and unbalanced outputs so that the preamplifier can interface withvirtually anything without hassle. But you knew all this anyway... which is why you bought it, so,thank you again, and please enjoy!GENERAL NOTESLOCATION & VENTILATIONThe Manley Microphone Preamplifier must be installed in a stable location with ample ventilation.It is recommended, if this unit is rack mounted, that you allow enough clearance on the top andbottom of the preamp such that a constant flow of air can flow through the ventilation holes.WATER & MOISTUREAs with any electrical equipment, this preamplifier should not be used near water or moisture. It isnever a good idea to pour a cup of coffee into your micpreamp.SERVICINGThe user should not attempt to service the preamplifier beyond that described in the owner's manual.Refer all servicing other than tube replacement to Manley Laboratories.SPECIAL NOTESTubes may become loose during transit. Check to see that all the tubes are seated smartly in theirsockets. Please note, the tubes do get very hot during operation and high voltages are present insidethe chassis, so take care if poking your fingers around inside the chassis.
