INTRODUCTION THANK YOU!... for choosing the Manley Euro 175 Monoblock Amplifiers. Designed by David Manley, the Manley Euro 175 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 Your amplifier has been factory set to the correct mains voltage for your country. The voltage setting is marked on the serial badge, located on the rear panel. Check that this complies with your local supply. 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 interconnects from the output of the preamplifier or switching center to the RCA input on the top rear 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 (See diagarm 2).

This has been proven to be the rugged and reliable of the 6L6 types and we strongly emphasize that only the 5881 should be used in this amplifier. The MANLEY 175 WATT MONOBLOCK has been thouroughly optimised around this tube.
BIAS PROCEDURES The Manley Euro 175 Monoblock Amplifiers uses a fixed bias system that requires very little attention. If you wish to adjust or check the bias, follow the following steps. We suggest that the bias be checked and reset every 3-4 months. 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 SWITCHING ON The power switch is located on the lower left hand corner of the front panel. Push the top of the rocker switch (1) to turn on the amplifier and the bottom of the rocker switch to turn off the amplifier. The LED and the back-lit insert panel will illuminate indicating that the amplifier is on. RUNNING It is not recommended that you leave your amplifier permanently switched on. This only wastes electricity and tube life.
