Setup Guide
1. Turn off your pre-amplifier or any other
equipment that the HCA-2 will be connected to.
2. Unpack the HCA-2 and place it on a smooth
surface. The HCA-2 may also be rack mounted
with an optional rack shelf. Due to the efficiency
of the design the HCA-2 does not need to be
placed in a ventilated area.
3. Choose either the single-ended (RCA) or
balanced (XLR) input connections on the back
of the HCA-2. Connect the outputs of your pre-
amplifier or source equipment to the back of the
HCA-2 marked “Right Input” and “Left Input.” Be
sure to match up the left and right conductors
appropriately.
Note: If connecting the HCA-2 to a powerd
subwoofer, ensure the subwoofer’s negative
input terminal is not grounded.
4. Connect your speakers to the HCA-2’s output
terminals, labeled “Right Output” and “Left
Output.” Be sure to connect the polarity of the
speaker cables correctly. Match the HCA-2’s
positive (red) and negative (black) terminals to
the corresponding speaker connections.
5. Plug the HCA-2 into a power source. Use
the supplied AC power cable or an aftermarket
power cable. For optimum results, we
recommend the use of a PS Audio xStream
Power Cable.
6. First, turn on your source equipment. Then,
turn on the HCA-2 by pressing the power button
on the left-hand side of the chassis.
7. The HCA-2 will go into standby mode for
about 15 seconds, indicated by the amber
“Standby” light on the front panel display.
8. Once the blue “Operate” light becomes
visible in the display, the HCA-2 is
ready to go.
