3. Connect the Loudspeaker hookup cables from a

single Loudspeaker to the output terminals that

match the impedance of the Loudspeaker

, being

careful to observe the correct polarities. Output

impedance connections of 2 ohms, 4 ohms and 8

ohms are provided. If the Loudspeaker’s imped-

ance is in-between the available connections, use

the nearest lower impedance connection.

WARNING: Loudspeaker terminals are hazard-

ous live and present a risk of electric

shock.

4. Connect the MA6600 Power Cord to a live AC

outlet.

2. Prepare the Loudspeaker Hookup Cables that

attach to the Amplifier by choosing one of the

methods below:

Bare wire cable ends:

Carefully remove sufficient insulation from the

cable

ends,

refer to

figures

1, 2 &

3. If the

cable is

stranded, carefully twist the strands together as

tightly as possible.

Note: If desired, the twisted ends can be tinned with

solder to keep the strands together, or attach

spade lug and/or banana connector.

Spade lug or prepared wire connection:

Insert the spade lug connector or prepared sec-

tion of the cable end into the terminal side ac-

cess hole, and tighten the terminal cap until the

cable is firmly clamped into the terminal so the

wires cannot slip out. Refer to figures 4, 5 & 6.

Banana plug connection:

Insert the banana plug into the hole at the top of

the terminal. Refer to figures A and B.

Note: Banana Plugs are for use in the United

States and Canada only.

Caution: The supplied AC Power Cord should not

be connected to the Rear Panel of the

MA6600 Amplifier until after the Loud-

speaker Connections have been made.

Failure to observe this could result in

Electric Shock. For additional instruction

on making Loudspeaker Connections con-

tact your McIntosh Dealer or McIntosh

Technical Support.

When connecting Loudspeakers to the MA6600 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:

Refer to the Connection Diagram located on the

separate folded sheet “Mc1B” when making Loud-

speaker Connections to the MA6600. This an example

of a typical audio system, your system may vary from

this, however the actual Loudspeakers would be con-

nected in a similar manner.

1. This McIntosh MA6600 Integrated Amplifier is

designed for the connection of a single Loudspeak-

er per amplifier channel, with an impedance of 2

ohms, 4 ohms or 8 ohms.

Note: The remaining Loudspeaker Terminals on the

Amplifier should not be connected to another

Loudspeaker.

For the best performance it is important to minimize

an impedance mismatch. An impedance mismatch can

occur when a Loudspeaker of a given impedance rating

is connected to the MA6600 Output Terminals with a

different impedance rating. For example, a Loudspeaker

with an impedance rating of 2 Ohm is connected the

MA6600 8 Ohm Output Terminals. The impedance of

a Loudspeaker actually varies as the Loudspeaker repro-

duces different frequencies. As a result, the nominal

impedance rating of the Loudspeaker (usually measured

at a midrange frequency) might not always agree with

the impedance of the Loudspeaker at low frequencies

where the greatest amount of power is required.
