INTRODUCTION THANK YOU!... for choosing the Manley 500/200 Monoblock Amplifiers. Designed by David Manley, the Manley 500/ 200 Monoblock Amplifiers use only the best available components, with the shortest and cleanest signal path possible, and with the use of our own in-house CNC machine shop we can provide you with a amplifier that looks as good as it sounds.
MAINS CONNECTIONS GENERAL NOTES LOCATION & VENTILATION The Manley 440/200 Monoblock Amplifiers must be installed in a stable location with ample ventilation. Allow a minimum of 2 inches of clearance on the top and sides of the amplifiers, such that a constant flow of air can flow. Do not place amplifiers directly on high pile carpet or any other surface that will block the ventilation vents underneath the amplifiers.
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. If using an UNBALANCED output from your preamplifier, connect the RCA interconnects from the output of the preamplifier or switching center to the RCA input on the back of the amplifiers. Select the rear switch to the UNBALANCED position. 3.

This has been proven to be the rugged and reliable of this type and we strongly emphasize that only the RUSSIAN 6550's should be used in this amplifier. The MANLEY 440/200 WATT MONOBLOCK has been thoroughly optimised around this tube. Use of unapproved tube types can and will void your warranty.

BIAS PROCEDURES The Manley 500/200 Monoblock Amplifiers uses 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. On page 8, which shows the FRONT panel of the amplifier, you can see 2 black tip jacks labeled READ BIAS.
OPERATIONAL NOTES SWITCHING ON -- SOFT START The MANLEY 500/200 is equipped with a SOFT-START circuit which lessens the initial stress the amplifier takes upon turn-on. We recommend that you use this soft start facility whenever you turn the amplifier on and especially when cold. 1. Ensure that the "mains" switch on the front panel is in the "off" or "0" position and the OPERATE / STANDBY switch is in the STANDBY mode. 2.
