Placement And Ventilation Guidelines - Parasound ZoneMaster 2350 Owner's Manual

Unpacking your ZoneMaster 2350 & Placement Guidelines
Unpacking Your ZoneMaster 2350
Carefully remove your ZoneMaster 2350 from its shipping carton and locate its AC power cord and these
included accessories:

One 12V trigger wire with mono 3.5mm mini plugs at both ends.

2U rack mounting kit

16AWG power cord
While you are unpacking your ZoneMaster 2350, 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 2350
should 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 2350's original packing.
Again: Do not throw away the carton or foam packing inserts.
Placement Guidelines
Install your ZoneMaster 2350 away from heat sources such as heating ducts, radiators, or other
heat-producing components. Always position the ZoneMaster 2350 horizontally. Observe the following
ventilation guidelines when installing the ZoneMaster 2350 in an equipment rack or any other enclosed space:
You should never install the ZoneMaster 2350 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 2350 tightly between other components. A ventilation
fan is also recommended where other heat-producing equipment must be mounted close to the ZoneMaster
2350.

Safety Caution
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 2350 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 2350 out of a cabinet to check or to
change connections without inadvertently disconnecting cables.
Rack Mounting Your Parasound ZoneMaster 2350
Brackets for mounting in a standard 19" equipment rack are included in the box with the ZoneMaster 2350.
The rack bracket "ears" attach to each side of the amplifier using the 4 screws on the sides. If you intend to
run the ZoneMaster 2350 into speaker loads less than 4 ohms 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.
AC Line Power Cord
Connect your sources and preamplifier before you plug in the AC cord. The power cord supplied with your
ZoneMaster 2350 is an IEC type 16AWG AC cord. The AC ground potential can vary between your AC
outlets and the result can be an audible 60Hz (or 50Hz) hum heard in your speakers. To help avoid this
problem plug your ZoneMaster 2350 into the same AC wall outlet, power strip or line conditioner as all your
other audio equipment.
