Connections

A word about safety
!
The XPR-1 is capable of delivering large voltages and currents at its speaker terminals.
If, while music is playing, the speaker terminals or speaker cables are inadvertently shorted
to each other, to interconnect cables, or to ground, the XPR-1 can cause damage to
associated equipment, and may even pose a risk of electric shock.
• Ensure that the XPR-1 is powered Off before changing any connections.
• Ensure that speaker wires are tightly secured before turning the XPR-1 On.
• Ensure that metal objects and stray wires do NOT come in contact with the speaker
terminals (on the XPR-1 and on the speakers) while the XPR-1 is turned On.
• Ensure that speaker wires aren't frayed or damaged, and are well insulated
(avoid using boutique speaker cables with thin or fragile insulation).
Choosing speaker cables
While the XPR-1 doesn't require special speaker cables, we strongly suggest that you
use heavy-gauge cables with low resistance that are capable of carrying large amounts
of current. Any standard cable of 10 gauge or heavier (lower gauge numbers are heavier)
will work well. Avoid cables that fail to provide the electrical equivalent of a 12 gauge or
heavier conductor. Using a cable that is too thin probably won't cause damage, but it will
significantly degrade the sound produced by your speakers (it will make the bass on some
speakers sound muddy and poorly controlled).
Connecting speakers to your XPR-1
The XPR-1 provides heavy duty gold plated audiophile grade five-way binding posts for
connecting a speaker.
• Always turn off the amplifier before connecting or disconnecting speaker cables or
signal source interconnects.
• Always verify that your speaker cables are firmly attached and not shorted to each other
or to any other cables before powering up your XPR-1.
• Always use high-quality speaker wire of reasonable gauge (10 gauge or heavier).
• Be careful to wire all speakers "in phase" (the plus/red terminal on each speaker to the
plus/red terminal on your amp).
• Try to use wires of equal length and gauge for both speakers in each pair. Use the same
gauge and length for both fronts, or for both surrounds; don't use a long 12 gauge wire
for one speaker and a short 10 gauge wire for the other.
• If you use stranded cables, use care to avoid short circuits from stray strands touching.
• Emotiva offers very high quality pre-made speaker cables at reasonable prices. You will
find them in the Interconnects section of our website at www.emotiva.com.
