Note: Refer to “Output Terminal” step 4 on 

page 10 for important information.

If the Loudspeaker’s impedance is in-between 

the available connections, use the nearest lower 

impedance connection. Refer to “General 

Information” Note 6 on page 6 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 Technical Support.

9. Connect the MC1502 Power Cord to an active AC 

outlet.

are indentified as 4Ω (ohms), 8Ω (ohms) or 16Ω 

(ohms) connection to match the impedance of the 

Loudspeaker, being careful to observe the correct 

polarities.

If the Loudspeaker’s impedance is in-between 

the available connections, use the nearest lower 

impedance connection. Refer to “General 

Information” Note 6 on page 6 for additional 

information.

Spade Lug or Wire Connections:

8. Connect the Loudspeaker hookup cables to the 

MC1502 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. 

Do 

not over tighten.

 Refer to figures 4, 5 and figure E.
