5. 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 Termi-

nals.

6. Place the IMPEDANCE Switch to

the position (4 ohm or 8 ohm) to match the imped-

ance of the connected Loudspeakers. In the event

that some of the Loudspeakers in the system are

different impedance, use the impedance of the

Front Loudspeakers. If the Loudspeaker’s imped-

ance is 6 ohms, select the 4 ohms setting. Refer

to “General Information” Note 4 on page 3 for

additional information.

WARNING: Loudspeaker terminals are hazardous

live and present a risk of electric shock.

For additional instruction on making

Loudspeaker Connections contact your

McIntosh Dealer or McIntosh Techni-

cal Support.

7. Connect the MC205 power cord to an active AC

outlet.

Spade Lug or Wire Connections:

8. Connect the Loudspeaker hookup cables to the

MC205 Output Terminal being careful to observe

the correct polarities. Insert the spade lug connec-

tor or prepared section of the cable end into the

terminal side access hole., Then tighten the termi-

nal cap until the cable is firmly clamped into the

terminals so the lugs or wire cannot slip out. Refer

to figures 6, 7 and 8.

3. Prepare the Loudspeaker Hookup Cable for attach-

ment to the MC205 Power Amplifier:

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:

4. Attach the previously prepared bare wire cable ends

into the banana plugs and secure the

connections. Refer to figure 4.

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 “Mc1A”, is an example of a typical Mul-

tichannel 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 4.

1. For Remote Power Control, connect a power control

cable from the A/V Control Center Power Control

Trigger/Output 1 to the Amplifier POWER CON-

TROL ZA input.

2. Connect XLR cables from the Balanced Outputs

(FL, C, FR, SR and SL) of an A/V Control Center

to the MC205 Balanced INPUTS (1-LF, 3-CTR,

5-RF, 4-RS and 2-LS) making sure to match up

channel designation.

Note: Unbalanced cables and connections may be

used instead of Balanced connections.

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:
