McIntosh components. A 3.5mm stereo mini plug
is used for connection to the trigger outputs on the
MHT300.
Data Out Connector
The MHT300 will convert IR remote control data
to share with McIntosh components connected to the
DATA OUT port on the rear panel. This will allow
the operation of primary functions of a source to be
operated with the MHT300’s remote control as well
as allow units that are out of range of an IR signal to
receive commands.
NET Port (Ethernet / 10baseT LAN)
Use an Ethernet cable to connect the MHT300 to
a network router. The network connector is located
on the rear panel of the MHT300 to the left of the
CAUTION label. It is labeled NET.
By default, the MHT300 has DHCP set to ON and
will automatically receive an IP address from the
router. This setting can be changed.

R, Ethernet, and ARC. Although HDMI is
backward compatible, older cables may have issues
with the higher bandwidth.
Use the HDMI OUT/eARC port when connect-
ing to an ARC (Audio Return Channel) enabled
tel
evision.

units allowing for volume control and lip-syncing
functions to ensure audio and video are perfectly
matched. This allows for more intelligent operation
between components as well as less cable clutter.
Make sure the ARC is enabled in your TV’s setup
menu.
The MHT300 supports eARC which allows for
even higher bandwidth and will allow for higher
quality audio including uncompressed 7.1 surround,
Dolby Atmos and DTS:X.
