PS Audio HCA-2 - Manual (Page 4)

1. 12 Volt Trigger
The HCA-2 is equipped with a 12 Volt DC input
trigger. The 12 Volt trigger can be used with
other 12 Volt trigger equipped products to relay
power status.
See “Using the 12 Volt Input Trigger” for more
information.
5. Fuse
The fuse is a 7 amp slow blow. It can be
removed by inserting a flat device into the fuse
holder’s slot and twisting counter-clockwise.
Note: Unplug the power cord before checking
the fuse.
3. PS Bus
The P500 comes equipped with a built in PS
Bus. The PS Bus allows other PS Audio products
equipped with a PS Bus to communicate via
standard RJ11 "twisted end" crossover cable.
Note: use only a “twisted end” crossover cable.
A standard phone cable will not work.
See “Using the PS Bus” for more information.
4. IEC Power Input
15 amp male IEC standard power socket.
5. PS Bus jumper switches
The jumper switches control the functionality of
the PS Bus. These settings are only functional
when connected to other PS Audio products via
the PS bus.
6. Speaker terminals
The 5-way WBT™ binding posts are capable of
accepting speaker cable with either spade lug,
banana plug, pin connector or bare wire.
Connect the left positive binding post (red
ring) of the HCA-2 to the positive (red or +) left
speaker cable lead. Connect the left negative
binding post (black ring) of the HCA-2 to the
negative (black or -) left speaker cable lead.
Do the same for the right terminals of the HCA-
2 and the right speaker. Be sure to hook-up the
speaker(s) in phase with the HCA-2; it should
be positive to positive and negative to negative.
The HCA-2 uses a balanced output design.
Therefore, the negative speaker terminal is not
common or ground.
Note: Do not operate the HCA-2 without
speakers connected.
7. Audio Inputs
There are two sets of inputs to choose from,
single-ended (RCA) and balanced (XLR).
The single-ended RCA connections are a very
high quality, gold plated connector designed
specifically for PS Audio components. The
HCA-2 is a fully balanced design, thus use of
the balanced XLR inputs is the optimal choice.
Since the gain is higher for balanced input, as
opposed to the single ended input, be sure to
use the inputs in matched pairs (in other words,
use both RCA inputs or both XLR inputs, but
never one of each).
