tion is for controlling the illumina-
tion of the Power Output Meters
1. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected
to the MA5300.
2. Apply AC Power to the MA5300 and other McIn-
tosh Component(s) only after all the system compo-
nents are connected together. Failure to do so may
cause a malfunction of system operations as the
Microprocessor’s Circuitry inside the components
is active when AC Power is applied.
3. The MA5300 includes an Auto Off Power Save
Feature and the default setting is enabled. For
additional information including how to disable it,
refer to page 21.
4. When Power Amplifier Protection Circuitry of
the MA5300 has activated, the Front Panel Power
Guard LEDs are illuminated continuously and the
sound will be muted.
5. When the Power Transformer has overheated due
to improper ventilation and/or high ambient operat-
ing temperature, AC Power is removed from the
MA5300. Normal operation will resume when the
operating temperature is in a safe range again.
6. For the best performance and safety, it is important
to always match the impedance of the Loudspeaker
to the Power Amplifier connections. Refer to pages
10 thru 12.
Note: The impedance of a Loudspeaker actually var-
ies as the Loudspeaker reproduces different
frequencies. As a result, the nominal impedance
rating of the Loudspeaker (usually measured at
a midrange frequency) might not always agree
with the impedance of the Loudspeaker at low
frequencies where the greatest amount of power
is required. Contact the Loudspeaker Manufac-
turer for additional information about the actual
impedance of the Loudspeaker before connecting
it to the McIntosh MA5300.
7. The MA5300 Remote Control is capable of operat-
ing other components. For additional information
go to www.mcintoshlabs.com.
8. The IR Input, with a 1/8 inch mini phone jack, is
configured for non-McIntosh IR sensors such as
a Xantech Model DL85K Kit. Use a Connection
Block such as a Xantech Model ZC21 when two
or more IR sensors need to be connected to the
MA5300. The signal from a connected External
IR Sensor will have priority over the signal from
the Front Panel IR Sensor.
9. When discarding the unit, comply with local rules
or regulations. Batteries should never be
thrown away or incinerated but disposed
of in accordance with the local regula-
tions concerning battery disposal.

Installation
Installation
The MA5300 can be placed upright on a table or
shelf, standing on its four feet. It also can be custom
installed in a piece of furniture or cabinet of your
choice. The four feet may be removed from the bottom
of the MA5300 when it is custom installed as out-
lined below. The four feet together with the mounting
screws should be retained for possible future use if the
MA5300 is removed from the custom installation and
used free standing. The required panel cutout, ventila-
tion cutout and unit dimensions are shown.
Always provide adequate ventilation for your
MA5300. Cool operation ensures the longest possible
operating life for any electronic instrument. Do not
install the MA5300 directly above a heat generat-
ing component such as a high powered amplifier. If
all the components are installed in a single cabinet, a
quiet running ventilation fan can be a definite asset in
maintaining all the system components at the coolest
possible operating temperature.
A custom cabinet installation should provide the
following minimum spacing dimensions for cool
operation.
Allow at least 6 inches (15.24cm) above the top, 2
inches (5.08cm) below the bottom and 2 inches (5.1cm)
on each side of the Integrated Amplifier, so that air-
flow is not obstructed. Allow 20 inches (50.8cm) depth
behind the front panel. Allow 1-7/6 inch (3.66cm) in
front of the mounting panel for knob clearance. Be
sure to cut out a ventilation hole in the mounting shelf
according to the dimensions in the drawing.

Sampling Rate (refer to figures 105 and 106 for PCM
Signals).
Figures 107 and 108 indicate a Sampling Rate of 128
or 256 times the Sampling Rate of a CD Disc for the
incoming DSD Digital Audio Signal.
The Sampling Rate and the Bit Rate are determined
by the original recording, the Application Output
Format (when available) and the McIntosh-HD Control
Panel Settings.
Note: In general, when the original music is recorded
at a higher Sampling Rate, the result is usually
more detail in the music. However, this higher
rate results in consuming larger amounts of stor-
age space. The Sample Rate usually should be set
to match the Sample Rate of the music recording
being played back.
There are many third party Applications (besides Ap-
plications like Windows Media Player) for steaming
music from the computer to McIntosh MA5300 USB
Input. An example of just one of the available applica-
tions is “JRiver Media Center”.
