INTRODUCTION THANK YOU!... for choosing Manley Laboratories' Langevin 150 Watt Solid State Amplifier. Designed around the concept that less is more, the Langevin 150 Watt Solid State Amplifier uses the best available parts with the shortest, cleanest, signal path possible. With the use of our own C.N.C. milling machine, we can provide you with a superb sounding machine with elegant packaging.
MAINS CONNECTIONS The Manley Laboratories' Langevin 150 Watt Solid State Amplifier requires a significant amount of AC current to operate properly. For best operation, plug the amplifier directly into the wall outlet, avoiding extension cords and other devices which restrict the current supply to amplifier. If extension cables are required, be certain that they are high quality, heavy duty (14-12 guage) cables. Your amplifier has been factory set to the correct mains voltage for your country.
CONNECTING YOUR AMPLIFIER Setting up your amplifier is rather easy. 1. Connect all source components (turntable, CD, Tuner, Tape DAT, etc.) to your preamplifier. 2. Connect the interconnects from the output of the preamplifier or switching center to RCA input. 3. Connect the hot or "+" speaker cable to the top binding post and the common or "-" speaker cable to the bottom binding post (See diagarm III). Ensure that the other end of the cable is connected correctly to the speaker.
REAR PANEL A IEC MAINS CONNECTOR Standard mains connector. Connect an IEC mains cable to a 50/60 Hz AC receptacle. B MAINS FUSE Use a 3 amp (110, 120 mains voltage) or a 2 amp (220, 240 voltage) SLO-BLO fuse. C GROUND BINDING POSTS Use to connect Chassis ground (Black) to Circuit Ground (Green) D RAIL FUSES Use only a 5 Amp FAST BLOW fuse in each voltage rail. E OUTPUT BINDING POST (-) Negative or common speaker terminal binding post.
OPERATIONAL NOTES SWITCHING ON With monoblocks we suggest that you turn on one amplifier first allowing about thirty seconds to pass before powering the other. Also, ALWAYS turn ON your preamplifier or console FIRST and let this settle before turning on the amplifiers. RUNNING It is not recommended that you leave your amplifier permanently switched on. This only wastes electricity. Your amplifier uses all solid state components and reaches peak operating condition in approximately 30 minutes.
