q POWER switch
Press the button to turn power on (POWER ON mode), and
press it again to turn power off (POWER OFF mode). When it is
required to remote control the power mode of the MM9000, be
sure to leave this switch in the POWER ON mode.
w STANDBY indicator
This indicator lights up when the unit is put to the STANDBY
mode by remote control or based on the video signal input.
In the STANDBY mode, the power supply to the internal circuit
of the amplifier is cut so the heat generation and power con-
sumption are minimized.
e POWER indicator
The indicator lights up when the power is on and the unit is
ready to output sound.
r PEAK indicators
When the output power of a channel is clipped momentary,
the corresponding indicator lights in red. If the indicators light
continuously in red, decrease the listening volume.
t INPUT LEVEL control
This control sets the amplifier's output level by adjusting its
input level.
When you use the MM9000 in a THX system, the knob must be
set to THX Ref. (Maximum position)
y AUDIO INPUT jack
Connect the preamplifier output to this jack.
u EXT. CONT IN jack
Not connected when the power is to be controlled from a MA-
RANTZ remote control unit.
Connect to the video signal output of a video component when
the power is to be controlled based on a video signal.
The external control allows to switch the "POWER ON" and
"STANDBY" modes of the unit according to the "presence" and
"absence" of video signal.
When the video signal becomes absent while the power of the
unit is on, it enters the "STANDBY" mode in about 4 seconds,
the unit enters the "POWER ON" mode again when the video
signal is input again.
External control using a signal from 5 to 13 V in place of video
signal is also possible using this jack. However, as this scheme
belongs to the professional use, please consult MARANTZ if
you want to adopt such an external control scheme.
i SPEAKER SYSTEM terminals
Connect with speakers using speaker cords. Respect the
+ and - polarity when connecting speakers.
o AC INLET
Connect AC cord (Supplied) and plug into a household AC
power outlet.
!0 RC-5 IN / OUT jack
If your system uses a Marantz remote control compatible com-
ponent with preamplifier outputs, such as an A/V preamplifier
or surround receiver, these jacks allow to turn the power of the
MM9000 to ON or OFF/Standby through remote control from
the preamplifier or receiver. Before using these jacks, check
the owner's manual of the Marantz component to see if it is
remote control compatible.
