Unpacking your
ZoneMaster 650 & Placement Guidelines
Unpacking Your ZoneMaster 650
Carefully remove your ZoneMaster 650 from its shipping carton and locate its AC power cord and these
included accessories:
Two 12V trigger wires with mono 3.5mm to 3.5mm mini plugs at both ends.
Left and right 1U rack mount side brackets and 4 bracket screws.
Two different size screwdrivers, the larger one is for the speaker output connectors
and the smaller one is for the speaker level input connector.
While you are unpacking your ZoneMaster 650, inspect it thoroughly for evidence of possible shipping
damage and tell your Parasound dealer immediately if you find any. If possible, save and store both the
inner and outer cartons and
–most especially–the foam packing inserts, to protect the ZoneMaster 650 if you
have to move it or ship it. This would be a good time to make a copy of your sales receipt for storage with
the ZoneMaster 650
’s original packing.
Again: Do not throw away the carton or foam packing inserts.
Placement Guidelines
Install your ZoneMaster 650 away from heat sources such as heating ducts, radiators, or other
heat-producing components. Always position the ZoneMaster 650 horizontally. Observe the following
ventilation guidelines when installing the ZoneMaster 650 in an equipment rack or any other enclosed space:
You should never install the ZoneMaster 650 in an unventilated equipment cabinet or compartment because
hot air will not exhaust adequately to prevent overheating. Even a cabinet or enclosure whose front and back
sides are open doesn’t guarantee that air will circulate adequately pockets of intense heat can still develop
around any heat-producing equipment. Allow a few inches of empty space on each side and above the unit
and try to avoid crowding or stacking the ZoneMaster 650 tightly between other components. A ventilation fan
is also recommended where other heat-producing equipment must be mounted close to the ZoneMaster 650.

Safety Caution
!
The ZoneMaster 650, as with any other high powered amplifier, could overheat
if it is installed in a confined space without adequate ventilation. Continuous overheating can damage an
amplifier and could ultimately pose a risk of fire.
If you are installing the ZoneMaster 650 yourself, use input and output cables that are long enough to leave
at least two feet of slack; that will enable you to pull the ZoneMaster 650 out of a cabinet to check or to
change connections without inadvertently disconnecting cables.
Rack Mounting Your Parasound ZoneMaster 650
Brackets and 4 screws for
mounting in a standard 19” equipment rack (1U of space) are included in the box
with the ZoneMaster 650. The rack
bracket “ears” attach to each side of the amplifier using the 4 screws
that are packed in the bag with the brackets. First remove and discard the 4 screws that come preinstalled
on the side of the amp. These are just installed for cosmetic reasons and will not be needed if the amp will
be rack mounted. If you intend to run the ZoneMaster 650 into speaker loads less than 4 ohms (or less
than 8 ohms when channels are bridged) adequate ventilation should be provided. To improve air flow
around the amp we recommend leaving at least 1 empty rack space above and below the amplifier. If more
than two amps will be racked mounted on top of each other (
“flat stacked”) a properly designed forced-air
ventilation system should be used.
