Your McIntosh MA6600 has been factory configured
for default operating settings that will allow immediate
enjoyment of superb audio without the need for further
adjustments. If you wish to make changes to the factory
default settings, a Setup Feature is provided to customize

MA6600. The MA6600 will go through a brief startup
intialization with the Front Panel Information Display
indicating the last used source and volume setting, this
is followed by the volume setting indication starting at
zero and then increasing to the last used volume set-
ting. Refer to

Trim Level Adjustment
Source Components can have slightly different volume lev-
els resulting in the need to readjust the MA6600 Volume
Control when switching between different sources. The
MA6600 allows the adjustment of levels for each of the
Source Inputs for the same relative volume. The CD1 and
SERVER Inputs are used in the following example.
Note: The range of adjustment is ± 6dB. The REC Output
Levels are unaffected by any changes in the Level Trim
Settings. The Trim adjustments made are retained in
permanent memory. They can be changed by perform-
ing a new Trim Procedure. The CD1 Input Volume
Level can serve as a reference or choose another
source frequently listened to. The reference Input
Source should be set to a Trim Level of 00.
1. Rotate the INPUT Control to select the CD1 Input and
adjust the VOLUME Control to the desired listening
level.
