AC VOLTAGE, INSTALLATION, AND RACK MOUNTING

AC Voltage Selector Switch.
Shown set for 230v.

115v - 230v AC Voltage Selector Switch

This switch is found on the chassis bottom. Make sure the 115/230V switch is set for the
correct AC line (mains) voltage before you connect the Ztuner v.2’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 Ztuner v.2 away from heat sources such as heating ducts, radiators, or other
heat-producing components. Always position the Ztuner v.2 horizontally.

Observe the following ventilation guidelines when installing the Ztuner v.2 in an equipment
rack or any other enclosed space:

You should never install the Ztuner v.2 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. Therefore, a ventilation fan is highly rec­ommended. Allow a few inches of empty space on each side and above the unit and try to avoid
crowding or stacking the Ztuner v.2 tightly between other components. A ventilation fan is also
recommended where other heat-producing equipment must be mounted close to the Ztuner v.2.

Do not place the unit on carpeting or any other material that could obstruct air flow into the
ventilation holes in its chassis bottom.

Rack Mounting

The Ztuner v.2 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 Zcustom model by using the
Parasound SBS (Side-by-Side) mounting kit. You can also mount a single Ztuner v.2 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 Ztuner v.2 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.
