PS Audio HCA-2 Back Panel, 1. 12 Volt Trigger, Fuse, PS Bus, IEC Power Input, Speaker terminals

Back Panel

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).
