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.
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:
9. Attach the previously prepared bare wire cable
ends into the banana plugs and se-
cure the connections. Refer to figure
4.
10. Referring to figure 5, connect the
Loudspeaker hookup cables with
banana plugs into the hole at the end
of the MC205 Negative and Positive
Output Terminals.
11. Place the IMPEDANCE Switch to the
position (4 ohm or 8 ohm) to match
the impedance of the connected Loudspeakers.
In the event that some of the Loudspeakers in the
system are different impedance, use the imped-

Zone B System (or Seven Channel System)
MC205 Balanced INPUTS (3-CTR, 4-RS and
2-LS), making sure to match up channel designa -
tion.
6. Connect audio cables from the A/V Control Cen-
ter Zone B Left and Right Channel Outputs to the
MC205 Unbalanced 2-LS and 4-RS, making sure to
match up channel designation.
Note: In a Seven Channel System perform step 6
instead of step 5.
7. In a Seven Channel System, connect XLR cables
from the Balanced Outputs (SBL and SBR) of an
A/V Control Center to the MC205 Balanced IN-
PUTS (5-RF and 1-LF), making sure to match up
channel designation.
This McIntosh MC205 Power Amplifier is designed
for Loudspeakers with an impedance of 4 ohms or
8 ohms. Connect a single Loudspeaker only to each
Channel Output Terminals.
When connecting Loudspeakers to the MC205 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:

8. Prepare the Loudspeaker Hookup Cable for attach-
ment to the MC205 Power Amplifier:
Caution: Do not connect the AC Power Cord to the
MC205 Rear Panel until after the Loudspeaker
Connections are made and the protective Termi-
nal Connections Cover is installed. Failure to
observe this could result in Electric Shock.
The connection instructions below, together with the
MC205 Connection Diagram located on the separate
folded sheet “ Mc1B ”. Below is an example of a typical
Five Channel and Zone B System (or Seven Channel
System). Your system may vary from this, however
the actual components would be connected in a simi-
lar manner. For additional information refer to “Con-
nector and Cable Information” on page 4.
1. For Remote Power Control, connect a power control
cable from the A/V Control Center Power Control
Trigger/Output 1 to Power Amplifier Two, Power
Control In.
2. Connect a power control cable from Power Amplifi-
er Two, Power Control Out to the MC205 POWER
CONTROL ZA Input.
3. Connect a power control cable from the A/V Con-
trol Center Power Control Trigger/Output 2 to the
MC205 Power Amplifier ZB Input.
Note: Do not perform this step in a Seven Channel
System.
4. Connect XLR cables from the Balanced Outputs
(FL and FR) of an A/V Control Center to Power
Amplifier Balanced Left and Right Inputs, making
sure to match up channel designation.
Note: Unbalanced cables and connections may be
used instead of Balanced connections.
5. Connect XLR cables from the Balanced Outputs
(C, SR and SL) of an A/V Control Center to the
