PLINIUS KORU

the preamplifier.  Make sure you connect the red coded cable to the red RIGHT RCA 
output, and the black (or white) cable to the white LEFT RCA output.  Also make sure 
the RCA connectors are a snug fit and are inserted all the way in.  

For XLR output connection, make sure you connect the RIGHT XLR output and LEFT 
XLR output to the right and left ‘line level’ inputs of your Preamplifier respectively.  Also 
make sure the XLR connectors click into place. 

NOTE: DO NOT connect XLR and RCA at the same time, use only one or the other. DO 
NOT connect the output of the Plinius Koru to a preamplifier phono input. Connect 
only to line level inputs such as CD, Tuner, Aux, etc.

CONNECTING THE MAINS SUPPLY

Firstly, check that the mains supply voltage printed on the rear of this preamplifi er is similar 
to the mains supply voltage in your area.  If in doubt, please consult your Plinius dealer.  
Mains supply power connection is via the plug-in lead supplied with your Plinius Koru. 
Where possible, check the wall outlet is switched OFF, then connect the local mains 
plug end of the lead to the wall outlet. Check the Koru is switched OFF, and connect 
the IEC end of the cable to the IEC socket at the back of the Koru. With the cord fully 
connected, switch the wall outlet ON.

Now that the Plinius Koru is configured correctly, switch the power switch on the rear 
panel to ON. You can now enjoy your new Plinius Koru Phono Preamplifier. 

NOTE: This unit must be connected to a mains socket outlet with a protective earthing 
connection. The wall outlet socket or mains switch must be accessible at all times in 
case of emergency.

WARM-UP PERIOD

You will find that the Plinius Koru will become noticeably ‘warmer’ in sound after being 
on for a period of time.  We usually recommend waiting at least 24 hours before 
expecting the best quality of sound reproduction from your preamplifier.
