Marantz AV7706 Frequently Asked Questions

  1. Where can I download the manual?

    You can download the manual from this link.

  2. Is it available on Amazon?

    Yes, it is available on Amazon via this link.

  3. What is the warranty?

    Marantz offers a 3-year manufacturer’s warranty.

  4. What is a preamplifier?

    A preamplifier is a component of an audio system that has the role of boosting the low-level outputs from audio components such as CD players and turntables, up to a line-level output that can be used on an amplifier or recording device. It acts as in between your audio sources and your amplifier.

  5. What would I need a preamplifier for?

    If you enjoy listening to music at lower volume levels then you may not require one, but for many people who don’t listen to high volumes, an integrated amplifier is a way to go. A dedicated pre-amplifier offers greater flexibility in terms of both input options and future upgradability due to its ability to be paired with higher-end power amps if you decide you want to take your system’s sound quality to the next level down the line. They are also great when used with powered speakers or headphones for maximum performance.

  6. Why would I want a high-resolution audio preamplifier?

    With an ever-increasing amount of people listening to music through their phones and via streaming services such as Spotify, it has never been more important to ensure that you are hearing your music exactly how it was intended to be heard by the artist who created it. High-resolution audio formats like FLAC and wav give you better sound quality than lossy (compressed) formats like mp3 and provide even more detail and deeper bass tones. They allow for higher bit depths and wider frequency ranges – every little nuance is captured, offering a truly authentic listening experience – which cannot be experienced when listening to lower resolution audio files the go.
