connections for 8Ω (ohms) Loudspeakers.

If the Loudspeaker’s impedance is in-between the 

available connections, use the nearest lower imped-

ance connection. Refer to “General Information” Note 

3 on page 3 for additional information.

WARNING: Loudspeaker terminals are hazard-

ous live and present a risk of electric 

shock. For additional instruction on 

making Loudspeaker Connections con-

tact your McIntosh Dealer or McIn-

tosh Technical Support.

9. Connect the MC152 power cord to an active AC 

outlet.

Output Terminals. The terminals are indentified 

as 2Ω (ohms), 4Ω (ohms) or 8Ω (ohms) connection 

to match the impedance of the Loudspeaker, being 

careful to observe the correct polarities.

7. Connect the MC152 power cord to an active AC 

outlet.

Spade Lug or Wire Connections:

8. Connect the Loudspeaker hookup cables to the 

MC152 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 figures 7 and 8.
