Unpacking & Placement Guidelines 

 
 
Unpacking Your Zphono XRM 

Carefully remove your Zphono XRM from its shipping carton and locate its AC power cord. While 
you are unpacking your Zphono XRM inspect it thoroughly for possible shipping damage and tell 
your Parasound dealer immediately if you find any. If possible, save and store the carton and the 
foam packing inserts, to protect the Zphono XRM if you have to move it or ship it. You may wish 
to flatten the cardboard cartons to save room in storage after cutting the taped seams on the 
bottom flaps.  This would be a good time to make a copy of your sales receipt to store with the 
Zphono XRM’s original packing. 
 
 

Placement Guidelines 

The Zphono XRM will be easier to use and will last longer if you follow these simple guidelines: 
 

 

Use output cables that are long enough to leave some slack; that will 
enable you to pull the Zphono XRM out of a cabinet to check or to 
change connections without inadvertently disconnecting cables. 

 

If you’re putting the Zphono XRM in a cabinet, it needs a space that’s at 
least 12 inches wide so you’ll be able to turn it around for access to its 
rear panel connections. 

 

Place your Zphono XRM where you can route turntable and output b 
cables as far as possible from any AC cords. 

 

Where signal cables must cross AC cords they should do so only at a 
90° right angle. 

 

We recommend that you do not place the Zphono XRM above a power 
amplifier or any other component which uses a large power transformer 
because noise could be picked up by the Zphono XRM. 
 

 

Rack Mounting Your Parasound Zphono XRM 

To rack mount the Zphono XRM you will need to purchase the optional Parasound ZRK (rack 
mount kit). Its panel height occupies 1-3/4” or 44.5

 

mm, one rack space (1U). 

 

 
 

 

 

 

115/230V AC Voltage Switch 

 

This switch is found on the underside of the chassis.

 

Make sure the 115

 

V/230

 

V switch is set for 

the correct AC line (mains) voltage 

before

 you plug in the Zphono XRM’s AC power cord. 

 
The Zphono XRM could be seriously damaged if the AC Voltage Selector switch is in the 
wrong position for your voltage! 

 

The 115

 

V setting is correct for North America where the Zphono XRM can operate safely with AC line 

voltages between 110

 

V-125

 

V. Most other countries will require the switch to be set to 230

 

V. With the 

230

 

V setting the Zphono XRM can operate safely with AC line voltages between 220

 

V-250

 

V.
