if the MA/MAC6700 is removed from the custom
installation and used free standing. The required panel
cutout, ventilation cutout and unit dimensions are
shown.
Always provide adequate ventilation for your MA/
MAC6700. Cool operation ensures the longest possible operating life for any electronic instrument. Do not
install the MA/MAC6700 directly above a heat generating component such as a high powered amplifier. If
all the components are installed in a single cabinet, a
quiet running ventilation fan can be a definite asset in
maintaining all the system components at the coolest
possible operating temperature.
A custom cabinet installation should provide the
following minimum spacing dimensions for cool
operation.
Allow at least 6 inches (15.24cm) above the top, 2
inches (5.08cm) below the bottom and 2 inch (5.1cm)
on each side of the Integrated Amplifier, so that air-
flow is not obstructed. Allow 20 inches (50.8cm) depth
behind the front panel. Allow 1-7/6 inch (3.66cm) in
front of the mounting panel for knob clearance. Be
sure to cut out a ventilation hole in the mounting shelf
according to the dimensions in the drawing.

How to Connect Loudspeakers
Caution: Do not connect the AC Power Cord to the MA/
MAC6700 Rear Panel until after the Loudspeaker Connections are made. Failure to
observe this could result in Electric Shock.
The connection instructions below, together with the
MA/MAC6700 Connection Diagram located on the
separate folded sheet “Mc2B”, is an example of a typical audio system. Your system may vary from this,
however the actual components would be connected in
a similar manner. For additional information refer to
“Connector and Cable Information” on page 5.
The McIntosh MA/MAC6700 Power Amplifier Circuitry is designed for Loudspeakers with an
impedance of 2 ohms, 4 ohms or 8 ohms. Connect a
single Loudspeaker only to the Right and Left Output
Ter m i na l s .
When connecting Loudspeakers to the MA/
MAC6700 it is very important to use cables of adequate size, so there is little to no power loss in the
cables. The size is specified in Gauge Numbers or
AWG (American Wire Gauge). The smaller the Gauge
number, the larger the wire size:

1. Prepare the Loudspeaker Hookup Cable for attachment to the MA/MAC6700 Power Amplifier:
Bare wire cable ends:
Carefully remove sufficient insulation from the
cable ends, refer to figures F, G & H. If the cable
is stranded, carefully twist the strands together
as tightly as possible.
Figure F
Notes: 1. If desired, the twisted ends can be tinned
with solder to keep the strands together.
2. The prepared bare wire cable ends may be
inserted into spade lug connectors.
3. Banana plugs are for use in the United
States and Canada only.

Banana Plugs are for use in the United States and
Canada only:
2. Attach the previously prepared bare wire cable ends
into the banana plugs and secure
the connections. Refer to figure I.
3. Rotate the Output Terminal Post
clockwise until it is nger tight.
Refer to gure J. Then using the
Figure I
McIntosh Wrench, rotate the top of
the Output Terminal one quarter of
a turn (90° ). Do not over tighten.
Refer to gure E.

or 8Ω (ohms) connection
to match the impedance of the Loudspeaker, being
careful to observe the correct polarities.
Note: The illustration located on the separate
folded sheet “Mc2B” is for connection to an
8Ω (ohms) Loudspeaker.
If the Loudspeaker’s impedance is in-between
the available connections, use the nearest lower
impedance connection. Refer to “General Information” Note 7 on page 4 for additional information.
WARNING: Loudspeaker terminals are hazard-
ous live and present a risk of electric
shock. For additional instruction on
making Loudspeaker Connections contact your McIntosh Dealer or McIntosh Technical Support.
