Use high quality cables to Interconnect the accessory equipment used with your
MA6400. This will ensure the best possible overall performance from your stereo system.
Your Mclntosh dealer can advise you on the type and length of cables best suited for your
specific Installation.
To minimize the possibility of hum pickup or Interference, locate the cables away from
AC power cords or loudspeaker cables.
1. CD1 CONTROL
Connect a Mclntosh CD control cable from the CD1 CONTROL connector to a matching
connector on a Mclntosh CD player or changer. This allows you to control CD player functions
with the MA6400 Hand Held Remote Controller transmitting to the MA6400 IR sensor.
A CD Control cable is included with each Mclntosh CD player or changer.
2. DATA PORTS
The DATA PORTS provide data signals to be fed to compatible audio and video accessory
components. This allows you to control the accessory components with their own remote
controllers transmitting to the MA6400 IR sensor.
The SUM DATA port is used for connecting to the optional Mclntosh Model RCT-2 Remote
Control Translator. Any IR signal transmitted to the MA6400 sensor results in data signals at this
port. The RCT-2 is a learning device that will allow the MA6400 to remotely control most major
brands of accessory components.
The VIDEO DATA port connects to the optional Mclntosh MVS-3 Audio/Video Selector. This
allows the MA6400 to select and switch up to five Audio/Video signal sources and a TV monitor
connected to the MVS-3.
All cables connected from the DATA ports use single conductor shielded wire with 1/8"
mini phone plugs. Connections are to the tip (+) and sleeve (-) of the plug. (Mclntosh Part
No. 170-202.)
3. PWR AMP IN (Left and Right); PWR AMP INPUT/ EXTernal-INTemal (Switch)
Set the PWR AMP INPUT switch to EXT to allow an external signal source or preamplifier to
feed signals directly to the MA6400 power amplifier section through the PWR AMP IN
connectors. This feature also allows you to add an additional signal processor or equalizer to
the MA6400 system. When the PWR AMP INPUT switch is in the EXT setting, the MA6400
preamplifier and power amplifier sections are disconnected from each other and are completely
independent. When the switch is set to the INT position, the MA6400 preamplifier section feeds
signals directly to the internal power amplifier section.
4. MAIN OUTPUTS
Connect cables from the MAIN OUTPUTS to the inputs of an external power amplifier. This
allows the MA6400 to feed signals simultaneously to both the internal power amplifier as well as
an external power amplifier. If you wish to use the MA6400 preamplifier independently to feed
