XPA HC-1
Connections
Connecting speakers to your XPA HC-1 monoblocks
Your XPA HC-1 has no special connection requirements; audiophile grade five-way binding posts
are provided for speaker connections.
• 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 XPA HC-1.
• Always
use high-quality speaker wire; 16-gauge or heavier.
• If you must use thinner wire, try to keep the length as short as possible.
• 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).
• If you are planning to bi-amp your speakers, make sure to remove the jumpers on the input
panel of each speaker. Failure to remove these will damage your amplifier.
Connecting an input source to your XPA HC-1
Your XPA HC-1 monoblock has both balanced (XLR) and unbalanced (RCA) inputs; the Input
Select switch determines which input is active. Be sure to set this switch correctly. If your source
component offers both types of outputs, a balanced connection is generally preferred, especially
for long cable runs and in noisy environments. We suggest using reasonably high quality cables,
keeping cables no longer than necessary, and avoiding running signal cables near power cables
and speaker cables whenever possible.
DO NOT connect a digital signal to the input of your XPA HC-1 (or you may damage your source 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 XPA HC-1 will switch On; when the trigger is
removed, the XPA HC-1 will return to Standby mode. The Trigger Output sends out
12 VDC whenever the main power to the XPA HC-1 is On (and NOT when it is in Standby mode)
which can be used to switch on other units with trigger capabilities.
