How to Connect for Five Channels

Caution: The supplied AC Power Cord should not be connected to the Rear Panel of the MC207 Amplifier until after the Loudspeaker Connections have been made. Failure to observe this could result in Electric Shock.

1.Connect Balanced Audio Cables from the Zone A Out- puts of a McIntosh A/V Control Center to the MC207 INPUTS (Channels 1-4 and 7), making sure to match up the channel identifications between both units.

Note: In place of the Balanced Audio Cables, unbalanced cables may be used. If a DB25 cable is used between the MULTI-CHANNEL INPUT of the MC207 and the Multi-Channel Output, the separate Power Control Cable ZA is not needed.

2.Connect a power control cable from the McIntosh A/V Control Center Zone A Power Control Out to the MC207 POWER CONTROL ZA.

3.Prepare the Loudspeaker Hookup Cables that attach to the MC207 Power 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 pos-

sible.

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 section of the cable end into the terminal side

access 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:

Tighten the top portion of the terminal post and insert the banana plug into the opening at the top of the ter- minal. Refer to figure 7.

Note: The use of Banana Plugs is for use in the United States and Canada only.

4.Connect the Loudspeaker Hookup Cables from the MC207 OUTPUT Terminals to the Loud- speakers, being careful to ob-

serve the correct polarities and channel designation.

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 Technical Support.

5.Place the IMPEDANCE Switch to the position (4 ohm or 8 ohm) that matches the impedance of the connected Loudspeakers. In the event that some of the Loud- speakers in the system are of different impedance, use the impedance of the Left and Right Front Loudspeak- ers to set the IMPEDANCE Switch position.

Note: If the two remaining channels (5 and 6) are to be used for Zone B operation, proceed to page 12.

6.Connect the MC207 Power Cord to an active AC out- let.
