INTRODUCTION THANK YOU!... for choosing the Manley 75 / 150 SE / PP 807 MONOBLOCK Amplifiers. Designed by David Manley, the 807 MONOBLOCK Amplifiers use only the best available components, with the shortest and cleanest signal path possible. These amps have the exclusive Manley ability to switch from Single ended to Push-Pull topologies. This amp is designed to provide our customers with a the unique combination of single ended triode topology, solid power and remarkable specs.
READ THIS PAGE BEFORE YOU SET UP THE AMPS, PLEASE IMPORTANT Never operate this amp without a speaker or load connected. Never drive this amp into a short circuit. Most solid state amps can be operated without a load or speaker and some can drive a short circuit because of protection circuitry. These are different - Like most tube amps the output power is less affected by changing the load impedance within the range of 4 to 16 ohms, however extremes like a short or open circuit are to be avoided.
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 or switching center. 2. Connect the interconnects from the output of the preamplifier 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).

OPERATIONAL NOTES SWITCHING SINGLE-ENDED 75 / PUSH-PULL 150 This amplifier has a feature exclusive to Manley Labs of being able to choose between two circuit topologies. You are able to switch between each mode while the amplifier is turned on and playing music. In SINGLE-ENDED mode the amplifier uses eight 807s in parallel. The advantage is a minimalist circuit requiring no "phase splitter",The disadvantage is a less efficient circuit that produces half the power of PUSH-PULL.
