Unpacking your
Zdac & Placement Guidelines
Unpacking Your Zdac
Carefully remove your Zdac from its shipping carton and locate its AC power cord and USB cable.
While you are unpacking your Zdac, inspect it thoroughly for 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 Zdac if you have to move it or ship
it. This would be a good time to make a copy of your sales receipt to store with the Zdac
’s original
packing.
Again: Do not throw away the Zdac carton or foam packing inserts.
Placement Guidelines
Install your Zdac away from heat sources such as heating ducts, radiators, or other
heat-producing components. Always position the Zdac horizontally. Observe the following
ventilation guidelines when installing the Zdac in an equipment rack or any other enclosed
space:
You should never install the Zdac in an unventilated equipment cabinet or compartment because hot air
will not exhaust adequately to prevent overheating. Air won’t often circulate adequately in a cabinet or
enclosure whose front and back sides are open; 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 Zdac tightly between other components. A ventilation fan is also
recommended where other heat-producing equipment must be mounted close to the Zdac.
If
you’re installing the Zdac 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 Zdac out of a cabinet to check
or to change connections without inadvertently disconnecting cables.
If you’re putting the
Zdac inside a cabinet, it needs a space that’s at least 11 inches wide so you’ll be able to
turn it around for access to its rear panel connections.
Rack Mounting Your Parasound Zdac (black Zdac only)
The Zdac occupies only half the width of a single rack space in a standard 19" equipment
rack. For rack mounting, you can fasten it to another Parasound Z model by using the Parasound
SBS (Side-by-Side) mounting kit (sold separately). You can also mount a single Zdac in the
rack with the accessory Zblank panel extender. The SBS includes four rack mount bolts plus four
pairs of plastic “shoulder washers.” The washers are important because they insulate the
Zdac front panel (and chassis) from the metal equipment rack and from the four mounting
bolts. Place these washers on both sides of the front panel before the mounting bolts are screwed
into the rack rail.
Note: Only black Zdacs can be rack mounted. Silver Zdacs cannot be rack mounted.
Note:
Tighten each bolt just enough to keep the unit secure in the rack to avoid deforming the
shoulder washers. Eliminating metal-to-metal contact reduces the likelihood of creating a ground loop
that might introduce hum into your system.
