UPA-500
Connections
Connecting speakers to your UPA-500
Your UPA-500 has no special connection requirements; standard five way binding posts are
provided for connecting one speaker to each channel.
•
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 UPA-500.
•
Always
use high-quality speaker wire of reasonable gauge (18 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 16 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.
Connecting an input source to your UPA-500
Your UPA-500 has a separate unbalanced (RCA) input for each channel. We suggest using
high quality, fully shielded cables, keeping cables as short as possible, and avoiding running
signal cables in parallel with power cables whenever possible.
DO NOT connect a digital signal to the inputs of your UPA-500, or you may damage it or
your speakers.
Connecting the Trigger Input and Trigger Output
The Trigger Input accepts a 12 VDC (nominal) trigger signal from another device via a
standard 1/8” mono plug. When the trigger is asserted, the UPA-500 will switch On; when
the trigger is removed, the UPA-500 will return to Standby mode. The Trigger Output sends
out 12 VDC whenever the main power to the UPA-500 is On (and NOT when it is in Standby
mode) which can be used to switch on other units with trigger capabilities.
