6 Unpacking W arning! DO NOT attempt to lift or move the Nº432/431 without adequate assistance. Failur e to follow the procedur es included in this section may r esult in personal injuries and/or product damage. The Nº432/431 are massive power amplifiers.
7 Installation Considerations The Nº432/431 requires special care during installation to ensure optimal performance. Pay particular attention to the precautions included in this section and to other precautions included throughout this owner’ s manual.
8 V entilation • DO select a dry , well-ventilated location out of direct sunlight. • DO allow at least a 2 to 3-inch (5 to 8cm) clearance above the Nº432/431 for proper heat dissipation through air circulation. The Nº432/431 is designed for passive, convection cooling.
9 The Nº432/431 is capable of passing remarkable musical signals regardless of signal and loudspeaker demands. On either an instantaneous or continuous basis, these power amplifiers can drive exceptional power levels into most all loudspeaker loads.
10 Operating States The Nº432/431 has four operating states: 1. Off Power is disconnected from the ~ac mains connector . 2. Sleep Mode Power is connected to a small power supply , communication circuits, and control cir cuits. When taken out of sleep mode , the Nº432/431 requires a brief warm-up and break-in period.
11 Special Design Featur es Thank you for purchasing the Nº432/431 Power Amplifier . While these amplifiers are straightforward in everyday use, they include several design features that are responsible for their outstanding performance.
12 Extensive Pr otection The Nº432/431 is designed to shut itself down if it senses any of a number of fault conditions that could cause damage to itself or to associated loudspeakers.

Indicator LED Indicates the operating state of the Nº432/431 and provides diagnostic information when a fault condition occurs.
14 2. Power Button Powers the Nº432/431 on and off when the power cord is connected to the ~ac mains connector and an electrical outlet. When the Nº432/431 is powered on, pressing and releasing the power button disconnects power from the ~ac mains connector and powers the Nº432/431 off.

16 Caution! NEVER connect power amplifier outputs to any component other than a loudspeaker . NEVER short-cir cuit power amplifier outputs. NEVER connect power amplifier outputs to another power amplifier’ s outputs. For best performance, use high-quality loudspeaker cables.
17 4. Balanced Input Provides left and right-channel audio input. One stereo XLR connector is available to accept balanced input signals from an associated pr eamplifier .
18 7. trigger in and out connectors Provide DC trigger control. One 1/8-inch mini-jack labeled trigger in is available to receive 12 or 5V DC signals from a connected component, and one 1/8-inch mini-jack labeled trigger out is available to pass these signals along to a connected power amplifier .
19 9. ~ac mains connector Provides power to the Nº432/431 through the supplied power cord when the supplied power cord is connected to the ~ac mains connector and the electrical outlet. One IEC-standard AC mains receptacle labeled ~ac mains is available.
20 Linking Linking is available for all Mark Levinson components that offer Link or communication ports, including master , slave in , slave out, , input, and contr ol communication ports. These communication ports can be used to “link” compatible Mark Levinson components in a slave chain, allowing them to share Link controls.
21 Constructing Link Link communication cables can be constructed using an Communication Cables 8-conductor modular telephone cable with the appropriate plug crimped on each end. • Use an 8-pin RJ-45 plug when connecting to a preamplifier . RJ-45 plugs provide an 8-pin connection.
Component Requir ements & Connections 22 • Must include components that are connected in a certain order to prevent communication from terminating. Power amplifiers such as the Nº432/431 must be the last components in a slave chain. Note The slave chains in this section include pr eamplifiers and power amplifiers.
23 Refer to the table on the previous page and to the illustration below for additional assistance. control Nº320S Preamplifier Step A: Connect the (or slave out) communication port on the preamplifier to the input communication port on the first power amplifier .
Pr eamplifier Power Amplifier Control Component 24 4. T ake the linked preamplifier out of standby . •A ll linked power amplifiers should come out of standby as well. If this does not occur , repeat steps 3 and 4. If problems persist, contact Mark Levinson Customer Service at 781- 280-0300 or www .
25 Tr oubleshooting Incorrect operation is sometimes mistaken for malfunction. If problems occur , refer to this section for troubleshooting information. If problems persist, contact Mark Levinson Customer Support at 781-280-0300 or www .marklevinson.
26 3. No audio and the front panel indicator LED is blinking slowly . • The Nº432/431 is in standby . T o take it out of standby , press and release the standby button . The Nº432/431 will power on. 4. No audio and the front panel indicator LED is blinking rapidly , r emaining lit most of the time.
27 7. No audio and the fr ont panel indicator LED is lit at full brightness. • The Nº432/431 is powered on, but is not passing a signal. Examine signal cables to ensure a solid connection between the Nº432/431 and the associated preamplifier and loudspeakers.
28 Car e & Maintenance The Nº432/431 requires routine care and maintenance to ensure optimal performance. The bulleted items included in this section indicate maintenance procedures that should be performed on a regular basis.
29 Specifications The correlation between published specifications and performance is unreliable. Measurements of your amplifier yield excellent results by any standards. However , only those specifications that apply to its actual operation are included here.
