How to Connect an External Power Amplifier
The MA6300 has the ability to be connected to an ex-
ternal Preamplifier and/or Power Amplifier. In the ex-
ample below, the MA6300 is connected to an external
McIntosh Power Amplifier and to a McIntosh Loud-
speaker with Bi-amplifer connections. The MA6300
Power Amplifier drives the Midrange/High Frequency
Section and the external Power Amplifier drives the
Low Frequency Section of the Loudspeaker.
1. Remove the McIntosh Jumpers connected between
the MAIN OUT and POWER AMP IN Jacks. Re-
tain them for future use.
2. Connect a pair of “Y” jumper adapters between the
MAIN OUT and POWER AMP IN Jacks.
3. Connect an Audio Cable from the just installed “Y”
jumper adapters to the unbalanced input jacks on
the external McIntosh Power Amplifier.
4. Connect a Control Cable from the MA6300 POW-
ER CONTROL Jack to the Power Control In on the
McIntosh Power Amplifier.
5. Using the same Loudspeaker connection methods
outlined on page 10, connect the MA6300 SPEAK-
ER Connections to the Midrange/High Frequency
Loudspeaker Connections. Connect the external
Power Amplifier LEFT and RIGHT OUTPUT
Connections to the Loudspeaker Low Frequency
Connections.
6. Connect the MA6300 Power Cord to a live AC
outlet.
