AC VOLTAGE, INSTALLATION, AND RACK MOUNTING
115v - 230v AC Voltage Selector Switch
This switch is found on the chassis bottom. The 115V position of this switch is correct for North
America; most other countries require setting it to 230V. Make sure the 115/230V switch is set
for the correct AC line (mains) voltage before you connect the Zpre2’s power cord and before
you install it. The unit may be seriously damaged if this switch is set incorrectly.

Installation and Ventilation Requirements
Install your Zpre2 away from heat sources such as heating ducts, radiators, or other heat producing
components. Always position the Zpre2 horizontally.
Observe the following ventilation guidelines when installing the Zpre2 in an equipment rack or any
other enclosed space:
We recommend that you place the Zpre2 beneath, rather than above, a power amplifier. Do
not install the Zpre2 in an unventilated equipment cabinet or compartment. Pockets of heat
can build up even in cabinets with open front and back sides. Therefore, a ventilation fan is
highly recommended.
Rack Mounting
The Zpre2 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 Custom model by using the
Parasound SBS (Side-by-Side) mounting kit. You can also mount a single Zpre2 in the rack with
the accessory Zblank panel. The SBS includes four rack mount bolts plus four pairs of plastic
“shoulder washers.” The washers are important because they insulate the Zpre2 front panel (and
chassis) from the metal equipment rack and from the four mounting bolts. Locate these washers
on both sides of the front panel before the mounting bolts are screwed into the rack rail.
