General Notes and Connector Information
1. When the MHT100 A/V System Controller is sold in North
America, the TM1 AM/FM Tuner Module for Radio Station
Reception is already installed. For MHT100 A/V System
Controllers sold outside of North America the optional
McIntosh TM1 AM/FM Tuner Module can be added. The TM1
is available from your McIntosh Dealer and can be installed
at any time, usually while you wait. Refer to page 50 for
additional information on the TM1.
2. The Main AC Power going to the MHT100 and any other
McIntosh Component(s) should not be applied until all the
system components are connected together. When the MHT100
and other McIntosh Components are in their Standby Power
Off Mode the Microprocessor’s Circuitry inside each
component is active and communication is occurring between
them. Failure to do so could result in malfunctioning of some
or all of the system’s normal operations.
3. Connecting Cables and Connectors are available from the
McIntosh Parts Department:
Data and Power Control Cable Part No. 170-202
Six foot, shielded 2 conductor, with 1/8 inch stereo mini
phone plugs on each end.
4. For additional connection information, refer to the owner’s
manual(s) for any component(s) connected to the MHT100
A/V System Controller.
5. System Setup operations must be performed in the order they
appear in the Main System Setup Menu as they are interactive.
6. The Zone A and Zone B IR Inputs, with 1/8 inch mini phone
jacks, are configured for non-McIntosh IR sensors such as a
Xantech Model 291-10. To avoid possible interaction, disable
the MHT100 Front Panel Sensor using the built-in switch. The
switch is recessed and available through an opening in the
bottom cover. The opening is located behind and to the right
of the Front Panel Sensor.
7. In order to hear bass frequencies below 80Hz, your system
must include either a Subwoofer or Large Front
Loudspeakers.

8. Zone B Audio is analog only, a Digital Audio Input Signal
Source will not appear at the Zone B Audio Outputs. The
source component Analog Outputs must also to be connected
to the MHT100.
9. When an assigned Digital Input and a matching Analog Input
are in use, the MHT100 automatically searches first for a
Digital Signal. If no Digital Signal is sensed, it switches to
the Analog Input.
10. Certain DVD or Laser Video Disc Players that are
reproducing Digital DTS Signals into a MHT100 Digital
Input, may only produce noise from their Analog Outputs at
the same time. If Zone B is turned on and that same input is
selected, that noise will be heard.
11. The MHT100 Input Source Name “DVD” is equivalent to
“V-Aux” on some McIntosh Keypads, Remote Controls and
Audio/Video Control Centers.
12. Up to four McIntosh Sensors or Keypads can be wired in
parallel for both Zones A and B.
13. When a McIntosh WK-2 Keypad or a R649 Sensor is to be
connected to the McIntosh MHT100 A/V Control Center
that uses a RJ-45 Connector Plug instead of the “F” Coax
Connector, connect the Center Conductor to Pin 1 and the
Shield Conductor to Pin 2. Refer to the illustration below.
14. There are three types of Video Signals that can be connected
to and selected by the MHT100; Composite, S-Video and
Component. Zone A and B, VCR 1 and 2 have both
Composite and S-Video Outputs; the Component Video
Output is for Zone A only.
15. There are four Power Control Jacks on the MHT100 that
can be used to switch on various electronic equipment. The
jacks labeled ZONE A, ZONE B and ACCessory are
designed for McIntosh Components. These three jacks
supply a Positive going twelve volt Turn-On Signal. The
jack labeled VIDEO supplies a twelve volt Turn-On Signal,
that can be set for either Positive or Negative going voltage.
16. The On-Screen Setup Menu and Operational features are
available at the MHT100 MON ZONE A Video Outputs (S-
Video or Composite). There is no On-Screen Information
present at the MHT100 Component Video Output.
