INTRODUCTION THANK YOU!... for choosing the Manley LAB SERIES Monoblock 100 watt Amplifiers. Designed by David Manley, the Manley Monoblock 100 watt Amplifiers use only the best available components, with the shortest and cleanest signal path possible. The circuit and the components used have been chosen carefully after years of development and refinement for reliability, constancy and most importanly, musical, accurate, and emotional delivery of the sound.
MAINS CONNECTIONS Export units for certain markets have a moulded mains plug fitted to comply with local requirements. If your unit does not have a plug fitted the coloured wires should be connected to the appropriate plug terminals in accordance with the following code.
CONNECTING YOUR AMPLIFIER Setting up your amplifiers is rather easy. 1. Connect all source components (turntable, CD, Tuner, Tape DAT, etc.) to your preamplifier. 2. Connect the RCA interconnects from the output of the preamplifier or switching center to the RCA input on the back of the amplifiers. 3. Connect the hot or "+" speaker cable to the red binding post and the common or "-" speaker cable to the black binding post. Ensure that the other end of the cable is connected correctly to the speaker.

BIAS PROCEDURES The Manley Monoblock 100 watt Amplifiers use a fixed bias system that requires very little attention. We recommend checking the bias every 2-3 months or any time you replace an output tube. To adjust or check the bias, follow the following steps. For this procedure you will need a voltmeter (a hand held autoranging DMM digital multimeter is the easiest) and a small flat screwdriver. 1.
OPERATIONAL NOTES TRIODE / TETRODE OPERATION: With the TRIODE / TETRODE switch, the amplifier may be set for TRIODE or TETRODE operation. When the switch is in the lower position, the amplifier is in TETRODE mode which will produce well over 100 watts.
