Onkyo TX-SR494 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?

    Onkyo offers a 2-year manufacturer’s warranty.

  4. What do I need to get started with the TX-SR494 A/V receiver?

    Connect cables between TV and source components* (Blu-ray Disc® player, etc.). Connect cables between power amp and speakers. Turn on TVs and devices connected with HDMI® cable. *If you are not using the preout terminals for bi-amping, set their volume level to a minimum (0).

  5. Can I place my subwoofer anywhere?

    The optimal listening position is likely somewhere between directly in front of your screen (“prime seat”) or slightly behind it (“corner” locations), but that’s not always possible. Try different locations around the room until you find the spot where the bass sounds best, regardless of where it looks best.

    The TX-SR494 A/V receiver adjusts the level of Zone B speakers automatically, letting you focus on just what you are listening to. It is even possible to listen to 2 channel sources in Zone B without being disturbed by the sound of large surround speakers emitting sounds from the opposite side of the room.

  6. What size speaker can I use with this receiver?

    This TX-SR494 A/V Receiver is compatible with front and center speakers ranging in size from small (3-1/2″) 2-way bookshelf models, up to large (13″ 3-way) floor-standing models that reproduce bass below 100 Hz – or any combination in between. A subwoofer output is line level, while speaker output is 70W per channel; some models may require external amplification (not included).

  7. I’m listening to multi-channel surround, but it sounds like some speakers are playing the wrong sounds. How can I fix this?

    The receiver outputs the audio signal from different sound areas to correspond to several channels being played back. For example, 2‑channel audio signals will be output from just front left and right speakers when a 2‑channel source is being played back or from front left, center, and right when a 3‑ channel source is being played back. However, if you play 5.1-ch sources with 7 full-range speakers set up in your room, each full-range channel will send the same sound to each speaker. Since the number of speakers is set to 7, effect sounds that are not included in the original surround track will be mixed with the center channel output.

  8. I enjoyed a more enveloping surround experience with my previous receiver because it was able to deliver a more powerful surround sound field. Doesn’t this receiver do that?

    No, there isn’t a need for such an ability anymore because Dolby Atmos and DTS: X immersive surround formats can produce virtual multidimensional sound fields from virtually any loudspeaker layout. With these new object-based surround formats, you don’t have to worry about finding or installing additional height or top-surround speakers, nor do you worry about how many speakers you have. With the new Dolby Atmos or DTS: X formats, if 5 height or top surround channels are available from a disc, those same 5 channels will be used for more enveloping sound regardless of the number of speakers in your home theater system!
