Dimensions
The following dimensions can assist in determining the best location for your MSA5500.
A Note on Placement:
It is important to keep your McIntosh unit out of direct sunlight and only use appropriate gentle cleaners because the organic anodize can become discolored
over time. While most products will maintain their classic dark features for their lifetime, some situations can accelerate discoloration. The most pervasive
culprit is UV light, especially light directly from the sun, or high intensity spotlights. Even high intensity short-term exposure can result in discoloration.
Chemicals can also alter the nish of the anodize. Aggressive cleaners will take their toll over time and actually etch away the anodize nish.

Balance
Listening balance varies with dierent program
sources, room acoustics and listening positions
relative to the loudspeakers. Use the Balance
(Trim Function) as needed to achieve approxi-
mately equal listening volume levels in each
loudspeaker.
The Front Panel Display indicates the Balance
changes are from 0 to 50 dB. After approximately
4 seconds the Information Display returns to
indicate the Source Selection and Volume Level.
To verify the Balance setting without changing it,
use the TRIM Button and select Balance.
Input Trim Level
Source Components can have slightly dierent
volume levels resulting in the need to readjust
the MSA5500 VOLUME Knob when switching
between dierent sources. The MSA5500 allows
the adjustment of levels for each of the Source
Inputs for the same relative volume.
