varies from country to country. Contact your Mc­Intosh Dealer for additional information.

5. When Power Amplifier Protection Circuitry of
the MA/MAC6700 has activated, the Front Panel
Power Guard LEDs are illuminated continuously
and the sound will be muted.

6. When the Power Transformer has overheated due
to improper ventilation and/or high ambient op­erating temperature, AC Power is removed from
the MA/MAC6700. Normal operation will resume
when the operating temperature is in a safe range
again.

7. For the best performance and safety, it is important
to always match the impedance of the Loudspeaker
to the Power Amplifier connections. Refer to pages
14 thru 16.

Note: The impedance of a Loudspeaker actually var-

ies as the Loudspeaker reproduces different
frequencies. As a result, the nominal impedance
rating of the Loudspeaker (usually measured at
a midrange frequency) might not always agree

4

General Information, Connector and Cable Information

with the impedance of the Loudspeaker at low
frequencies where the greatest amount of power
is required. Contact the Loudspeaker Manufac­turer for additional information about the actual
impedance of the Loudspeaker before connecting

it to the McIntosh MA/MAC6700.

Installation

Installation

The MA/MAC6700 can be placed upright on a table
or shelf, standing on its four feet. It also can be custom
installed in a piece of furniture or cabinet of your
choice. The four feet may be removed from the bottom
of the MA/MAC6700 when it is custom installed as
outlined below. The four feet together with the mount­ing screws should be retained for possible future use
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.

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.

6. Connect the Loudspeaker hookup cables to the
MA/MAC6700 Negative Output Terminal and

Positive Output Terminal indentified as 2Ω
(ohms), 4Ω (ohms) or 8Ω (ohms) connection to

match the impedance of the Loudspeaker, being
careful to observe the correct polarities. Insert
the spade lug connector or prepared section of the
cable end into the terminal side access hole, and
tighten the terminal cap until the cable is firmly
clamped into the terminals so the lugs or wire can­not slip out. Refer to fgures L and M.
