For those in the midst of assembling a home audio system, one component that raises a lot of questions is the pre-amplifier. After all, if you already have a powerful amplifier and quality speakers, why do you need another piece of equipment? In a high-performance AV separates setup, a pre-amplifier plays a crucial role. It's important to understand its function and what to look for when purchasing one.

Why do I need pre-amplifier?

As the name suggests, the pre-amplifier is the first stop for audio signal before it travels through the amplifier and into your speakers. In a home theatre system, the pre-amplifier performs two main functions: it handles switching between different line level sources and boosts the signal before sending it to the amplifier. A weak electrical signal becomes strong enough for additional processing, preventing noise and offering cleaner output.

If you have an AV receiver with an integrated preamp, you don't need a dedicated pre-amplifier. However, many home theatre enthusiasts prefer a separates setup with both a pre-amplifier and amplifier because this arrangement can deliver richer, fuller sound with minimal distortion. The higher gain and independent power supply per component provide the clean sound audiophiles crave.

Do you need a pre-amplifier? If you have several different sources to connect, such as a turntable, CD player or Network Audio player, then yes. The more sources you intend to connect, the more a pre-amplifier benefits you. It serves as the control centre for your audio players and provides proper signal routing, optimal performance and true audiophile sound.

To achieve sonic perfection, choose a pre-amplifier that offers the best performance to suit your needs, focusing on how the engineering and features of each component adds to the sound of your home theatre.

Choose the best pre-amplifier for your home theatre audio setup

Just like amplifiers and AV receivers, pre-amplifiers have undergone significant leaps forward in the features they offer over recent years. To enjoy ultra-high-definition video and high-resolution audio to their fullest, look for a pre-amp that combines impeccable construction with support for the latest in entertainment.

The Marantz AV8805 is built with the minute attention to detail that enables truly exceptional sound, plus the technology to stay on the cutting-edge for years to come. The preamp provides 13.2 channel processing compatible with popular 3D audio formats like Dolby Atmos, DTS:X and Auro-3D, so listeners can make the most of their speaker setup for a cinematic experience. Meanwhile, wireless capabilities bring the versatility to enjoy music from a wide range of sources and create a multi-room system.

Above all, a pre-amp needs to deliver a clean, powerful signal that lets your amplifier and speakers perform at the highest level. In the AV8805, all channels have AK4490 32-bit digital-to-audio converters laying a foundation for engaging sound by decoding files with extreme precision. Hyper Dynamic Amplifier Modules with discrete circuit elements offer ultra-wide-band response, contributing to a broad, nuanced soundstage.
