1. Connect the MA6850 power cord to a live AC outlet.
2. Connect the loudspeaker cables to the appropriate ter-
minals for your loudspeakers, being careful to observe
the correct polarities. Output impedance connections of
2 ohms. 4 ohms and 8 ohms are provided. If the imped-
ance of your loudspeakers is rated at other than the
listed impedance connections, use the nearest lower
connection.
NOTE: To prevent the possibility of
user contact with potentially
dangerous voltages, install the
protective cover(s) over the
loudspeaker output terminals
after the loudspeaker cables
have been connected. The
covers and cover mounting
screws are located in an
accessory package that is enclosed in the amplifier
shipping carton. There are two types of screws in the
package. Install the protective covers with the Phillips,
6-32 by 5/16 inch self tapping screws. The other screws
are No. 6 by ½ inch wood screws used to secure the
amplifier custom mounting brackets to a shelf.
3. Connect a cable from the TAPE 1 OUTPUTS to the
Record Inputs of a tape recorder and the TAPE 1 IN-
PUTS to a tape recorder Outputs. Connect a second
tape in the same manner to the Tape 2 inputs and out-
puts.
4. Connect cables from a McIntosh CD Player to the CD1
INPUTS. Connect a second CD Player to the CD-2 IN-
PUTS. Connect a McIntosh tuner to the TUNER IN-
PUTS.
5. Connect a cable from the POWER CONTROL jack to
the Power Control In on a McIntosh component or
Power Controller.
6. Connect a cable(s) from the DATA PORTS to the com-
ponents that are to be controlled by the MA6850.
NOTE: If a Signal Processor is used in either the Record or
Listen channels, connect cables from the Signal
Processor Outputs to the Processor From jacks, and the
Signal Processor Inputs to the Processor to jacks.
Activate the signal process circuits as needed with the
front panel Lis Proc or Rec Proc push-buttons.
