Placement And Ventilation Guidelines - Parasound Z Custom Owner's Manual

Unpacking your Zpre3 & Placement Guidelines
Unpacking Your Zpre3
Carefully remove your Zpre3 from its shipping carton and locate its AC power cord and these included
accessories:

One 12V trigger cable with mono 3.5mm mini plugs at both ends.

One 12V trigger cable with a mono 3.5mm plug on one end and a 2.5mm plug on the other end.

Remote control and two AAA batteries.
While you are unpacking your Zpre3, 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 Zpre3 if you move it or have to ship it.
This would be a good time to make a copy of your sales receipt for storage with the Zpre3's original packing.
Placement Guidelines
Install your Zpre3 away from heat sources such as heating ducts, radiators, or other
heat-producing components. Always position the Zpre3 horizontally. Observe the following ventilation
guidelines when installing the Zpre3 in an equipment rack or any other enclosed space:
You should avoid install the Zpre3 in an unventilated equipment cabinet or small compartment because hot air
will not exhaust adequately to prevent overheating. Even a small 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 Zpre3 tightly between other components.
If you are installing the Zpre3 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 Zpre3 out of a cabinet to check or to change connections
without inadvertently disconnecting cables.
Rack Mounting Your Zpre3
A rack mount adapter model "ZRK" is available for purchase separately. This kit allows two half width
ZoneMaster or Z Custom units to be installed in a rack side by side. Included in the kit is also a panel extender
to rack mount a single Zpre3.
AC Line Power Cord
Connect your sources and preamplifier before you plug in the AC cord. The power cord supplied with your
Zpre3 is an IEC type 18AWG 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
Zpre3 into the same AC wall outlet, power strip or line conditioner as you have plugged in your power
amplifier and other audio components. The power cord might be different for units sold in other regions of the
world.
