Making Connections to the HCA-2205A

Refer to Figure #1

Leave the AC cord disconnected before making any signal or speaker connections. When making connections to the amplifier, make sure there is no strain or tension on the input leads, speaker wires, or AC cord that could cause them to pull loose.

Your HCA-2205A is designed to deliver the same power and sonic characteristics to the Left, Center, Right, and both Surround speakers of your home theater system. For additional low frequency response, we recommend that you install a powered subwoofer. Even though all the channels of the HCA-2205A operate identically, the input and output connectors are color coded to make it easier to identify each channel in case you ever need to troubleshoot your system.

Input Connections

〈Connect the left front output of your processor to the White Channel 1 Input of your HCA-2205A

〈Connect the right front output of your processor to the Red Channel 2 Input of your HCA-2205A

〈Connect the center output of your processor to the Green Channel 3 Input of your HCA-2205A

〈Connect the right surround output of your processor to Blue Channel 4 Input of your HCA-2205A

〈Connect the left surround output of your processor to the Blue Channel 5 Input of your HCA-2205A

〈Connect the subwoofer output of your processor to the input of your powered subwoofer.

Speaker Connections

You may connect bare wire up to AWG 12, speaker wire terminated with 1/4" spade lugs, or banana plugs to the five-way binding posts of your power amplifier. If you use bare wire without terminals, make sure you remove only enough insulation so the wire can fit through the hole that runs sideways through the terminal’s binding post. Before inserting the wire, twist all its strands tightly to prevent strays that could cause a short circuit. (You may want to "tin" the stripped wire with solder to prevent it from fraying and oxidizing.)

Minimum Speaker Impedance Precautions

Although the HCA-2205A is capable of driving speakers with occasional impedance dips below 2 Ω, it is primarily designed to drive loudspeakers with a 4 Ω or 8 Ω nominal impedance. This is because sustained high power operation into loads of less than 4 Ω may cause overheating and subsequent thermal shutdown.

Observing Correct Polarity

When you connect speakers to your amplifier, you will notice that one side of the two conductor speaker wire will have some sort of mark: either printing, a raised ridge on the insulation, or a different color of conductor to let you know which wire to connect to the positive and which to the negative speaker terminals so you can repeat the connection on the power amplifier's binding posts.

HCA-2205A specifications

The Parasound HCA-2205A is a powerful, multichannel power amplifier that has cemented its place among audiophiles and home theater enthusiasts since its release. Known for its robust performance, the HCA-2205A delivers an impressive 220 watts per channel into 8 ohms and 350 watts per channel into 4 ohms. This high power output, combined with its advanced circuitry, ensures dynamic and clear sound reproduction, making it an excellent choice for high-fidelity audio systems.

One of the defining features of the HCA-2205A is its five-channel configuration. This allows users to build a comprehensive surround sound system, supporting both home theater and music listening environments. The ability to power multiple channels from a single unit simplifies wiring and reduces equipment clutter, providing an efficient solution for audio setups.

The HCA-2205A utilizes a direct coupling design, bypassing capacitive coupling, which enhances its overall sound quality by minimizing distortion and preserving transient response. Additionally, it is equipped with a toroidal power transformer that contributes to its clean power delivery and improved efficiency. This design choice helps to keep the amplifier's performance consistent, even during demanding audio passages.

Moreover, the amplifier features an impressive signal-to-noise ratio, ensuring that the sound remains clean and free from unwanted noise artifacts. This is particularly important for home theaters where dialogue clarity and immersive sound effects are essential. Parasound's commitment to high-quality components is evident in the use of premium capacitors and resistors throughout the HCA-2205A, further enhancing its sonic performance.

Thermal management is another highlight of the HCA-2205A. The unit is designed with substantial heat sinks and ventilation to handle extended listening sessions without overheating. It also incorporates a fan-less design, providing a quiet operation that aligns perfectly with high-end audio environments.

In summary, the Parasound HCA-2205A stands out for its high power, cutting-edge design, and superior sound quality. With its five-channel capability, exceptional build quality, and advanced engineering, it offers a remarkable audio experience for both music lovers and home theater aficionados alike. Whether used in a dedicated listening room or as part of a comprehensive AV setup, the HCA-2205A continues to impress with its reliable performance and fidelity.
