SAFETY
INSTRUCTIONS
READ BEFORE OPERATING EQUIPMENT
This product was designed and manufactured to meet strict quality and safety standards. There are, however, some installation and operation precautions which you should be particularly aware of.
1.Read Instructions - All the safety and operating instructions should be read before the appliance is operated.
2.Retain Instructions - The safety and operating instructions should be retained for future reference.
3.Heed Warnings - All warnings on the appliance and in the operating instructions should be adhered to.
4.Follow Instructions - All operating and use instructions should be followed.
5.Water and Moisture - The appliance should not be used near water - for example, near a bathtub, wash-bowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc.
6.Carts and Stands - The appliance should be used only with a cart or stand that is recommended by the manufacturer.
7.An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the appliance and cart combination to over turn.
8.Wall or Ceiling Mounting - The appliance should be mounted to a wall or ceiling only as recommended by the manufacturer.
9.Ventilation - The appliance should be situated so that its location or position does not interfere with its proper ventilation. For example, the appliance should not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or, placed in a built-in installation, such as a bookcase or cabinet that may impede the flow of air through the ventilation openings.
10.Heat - The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce heat.
11.Power Sources - The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance.
12.Grounding or Polarization - The precautions that should be taken so that the grounding or polarization means of an appliance is not defeated.
13.Power-Cord Protection - Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.
14.Cleaning - The appliance should be cleaned only as recommended by the manufacturer.
15.Nonuse Periods - The power cord of the appliance should be unplugged from the outlet when left unused for a long period of time.
16.Object and Liquid Entry - Care should be taken so that objects do not fall and liquids are not spelled into the enclosure through openings.
17.Damage Requiring Service - The appliance should be serviced by qualified service personnel when:
A:The power-supply cord or the plug has been damaged; or
B:Objects have fallen, or liquid has spilled into the appliance; or
C:The appliance has been exposed to rain; or
D:The appliance does not appear to operate normally or exhibits a marked change in performance; or
E:The appliance has been dropped, or the enclosure damaged.
18.Servicing - The user should not attempt to service the appliance beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel.

1. INTRODUCTION
Thank you for purchasing the Marantz MM9360 or MM9340 power amplifier for your sound system. Please take a few minutes to read this manual thoroughly, before you attempt connections and operations.The illustrations used in this manual refer to the six channel MM9360, but the MM9340 operates in the same manner, only with four channels and more power per channel.
This Marantz appliance is a Multi channel power amplifier, that is designed for home theatre and high quality audio systems.
2. FEATURES
The MM9360 is a six channel power amplifier, and the MM9340 is a four channel power amplifier developed for use in hi-fi AV systems.
-It is a high-power amplifier with efficient MOSFET highspeed switching output stages, controlled by internal microprocessor and DSP algorithms. Rated outputs per channel are 150W / 8 ohms for the MM9360 and 275W / 8 ohms for the MM9340.
-It is provided with the MARANTZ RC-5 remote control capability so its power can be controlled from a MARANTZ preamplifier or surround receiver (MARANTZ remote control compatible products).
-The power amplifier is equipped with LED indicators for signal present, peak power, thermal status, and protect mode for each channel.

- The power amplifier will accept RCA, 1/4" jack, or XLR input connectors.
3. NAMES AND FUNCTIONS
1. SIGNAL indicator
The signal present LEDs illuminate at an input level of about 13mVrms (-35.5dBu).
2. PEAK indicator
The clipping LEDs illuminate at an input level of about 870mVrms (+1.0dBu), with all channels driven by 1KHz into 8Ω. This indicates that the signal processing circuitry has determined output levels to be approaching the available power supply rails and has begun to “soften” signal peaks. Actual onset of “hard” clipping depends on audio program and total load impedance and does not occur until the signal processing circuitry can no longer compensate, which means that signal integrity can be maintained even if the clipping indicators illuminate for short periods of time.
3. THERMAL indicator
The thermal LEDs illuminate when the temperature of any one of the heat sink extrusions reaches 85 to 90°C. Both channels of the affected amplifier module will shut off until the measured temperature drops below about 70°C. The amplifier should be able to maintain proper operation at an ambient room temperature of 50°C (122°F) or less with typical audio program and all channels driven into 4Ω.
