Connections

NOTE

• Do not plug in the power cord until all connections have been completed.
• Do not bundle power cords together with connection cables. Doing so can result in humming or noise.

Cables used for connections

Provide necessary cables according to the devices you want to connect.

Speaker cable
Audio cable
Remote connector cable

Connecting speakers

NOTE

• Disconnect this unit's power plug from the power outlet before connecting the speakers.
• Connect so that the speaker cable core wires do not protrude from the speaker terminal. The protection circuit may be activated if the core wires touch the rear panel or if the + and - sides touch each other. ("Protection circuit")
• Never touch the speaker terminals while the power cord is connected. Doing so could result in electric shock.
• Use speakers with an impedance of 4 – 16 Ω/ohms.

Connecting the speaker cables

Carefully check the left (L) and right (R) channels and + (red) and - (white) polarities on the speakers being connected to this unit, and be sure to connect the channels and polarities correctly.

1. Peel off about 10 mm of sheathing from the tip of the speakercable, then either twist the core wire tightly or terminate it.
   
2. Turn the speaker terminal counterclockwise to loosen it.
   
3. Insert the speaker cable's core wire to the hilt into thespeaker terminal.
   
4. Turn the speaker terminal clockwise to tighten it.
   

Spade lug connector

Speaker connection

Connecting a playback device

You can connect turntables, tuners, Blu-ray disc players, network audio players and CD players to this unit. Use the cartridge selector knob on the front panel to set the phono equalizer on this unit according to the type of turntable cartridge to be connected.
If you set this unit's input source to "PHONO" and you accidentally increase the volume without having a turntable connected, you may hear a hum noise from the speakers.

NOTE: The earth terminal (SIGNAL GND) of this unit is not for safety grounding purposes. If this terminal is connected when there is a lot of noise, the noise can be reduced. Note that depending on the turntable, connecting the ground line may have the reverse effect of increasing noise. In this case, it is not necessary to connect the ground line.

The PHONO input terminals are equipped with a short pinplug. Remove this plug to connect a record player. Store the removed short pin-plug in a safe place so as not to lose it.

Connecting a recording device

NOTE: Never insert the short-circuiting pin plug into the recording output connectors (AUDIO OUT RECORDER). Doing so could result in damage.

Connecting a pre-amplifier or power amplifier

Connect a power amplifier to the unit to use it as a pre-amplifier, or connect a pre-amplifier to the unit to use it as a power amplifier.

When connecting a pre-amplifier and using this unit as a power amplifier, switch the input source to "PWR AMP".

NOTE: Never insert the short-circuiting pin plug into the PRE OUT connectors. Doing so could result in damage.

Connecting devices with remote control connectors

Performing operations by RC on this unit without visual contact

You can connect an external IR receiver to the REMOTE CONTROL connectors to perform operations on this unit with the supplied remote control unit without visual contact. This might be necessary if the unit is hidden in a cupboard or corner, so you can't directly point with the remote control unit to the device.

Remotely connecting Marantz audio devices

You can transmit remote control signals simply by connecting a Marantz audio device to the REMOTE CONTROL IN/OUT connectors using the remote connection cable provided with the device.
Set the remote control switch located on the rear panel of the connected audio component to "EXTERNAL" to use this feature.

Connecting the power cord

After completing all the connections, insert the power plug into the power outlet.

Settings

Setting the display's brightness

The display brightness can be adjusted between four levels. Switching the display off reduces a source of noise that affects sound quality, enabling higher sound quality playback.

1. Press DIMMER.
   • The brightness of the display switches each time the button is pressed.

• If button operations are made while the display is off, information is temporarily displayed at the brightest setting.
• The display brightness is set to most brightly by default.
• DIMMER also works with Marantz Network SACD player SACD 30n (sold separately), so its brightness can be adjusted simultaneously when used in combination with this unit. If the devices have different brightness settings, press and hold DIMMER for 5 seconds or longer and adjust after they are both at the brightest setting.

Setting the lighting LED brightness

Lighting LED brightness can be adjusted in 4 levels. It can also be linked with the display's brightness. Switching the lighting off reduces a source of noise that affects sound quality, enabling higher sound quality playback.

1. Press and hold TONE/BALANCE for 5 seconds or more.
   The lighting setting menu is displayed on the display.

   "Auto STBY On" or "Auto STBY Off" is displayed on the display.

Setting remote control codes

Remote control codes are set between this unit and the supplied remote control. You can select one of the three types of remote control codes, and the remote control can be used to control the unit when the same remote control code is used. If three of these units are used in the same location, all three units can be controlled simultaneously using one remote control in the default settings. By setting individual remote control codes between a unit and the remote control, the remote control can be used to control only the unit that has the same remote control code.
Be sure to check the operation of each unit after setting the remote control codes.
The default setting is "AMP1".

• When remote control code setting is set to "AMP1", the input source for this unit cannot be switched to "PWR AMP" using INPUT on the remote control. To switch with the remote control, change the remote control code setting to "AMP2" or "AMP3".

Explanation of terms

MM/MC cartridge
There are two types--MM (Moving Magnet) and MC (Moving Coil)--of cartridges for turntable. As the output levels for these two types of cartridges differ, the setting of the phono equalizer that is mounted in this unit must be switched according to the type of cartridge for your turntable. The setting can be switched by the cartridge selector knob on the main unit.

Speaker impedance
This is an AC resistance value, indicated in Ω (ohms).
Greater power can be obtained when this value is smaller.

Protection circuit
