The Onkyo TX-SR494 AV receiver is an analogue model of the TX-SR393 receiver, but the number of channels in it has been increased to seven. In addition to the updated design, which made the device more attractive in appearance, the Onkyo TX-SR494 has a slightly changed set of connectors – in particular, the USB port for connecting portable storage devices with music files has disappeared from its front panel.
Two key features present in the Onkyo TX-SR494 are Dolby Atmos Height Virtualizer and DTS Virtual: X. The new Dolby Atmos Height Virtualizer and DTS Virtual: X virtual surround technologies allow you to create a three-dimensional sound field without using real height speakers. These revolutionary technologies simulate the output signal from “virtual” height speakers and surround speakers if they are physically absent in the room. This provides greater flexibility when installing Dolby Atmos and DTS: X speakers.
Despite its quite affordable price, the Onkyo TX-SR494 is perfect for creating a modern home theater in a small room of an average city apartment. The device is easy to set up and use and will provide high-quality sound in computer games, when watching movies or listening to music.
The AV receiver is equipped with four HDMI inputs and one output, with the ability to transmit a 4K UHD signal including Dolby Vision, HDR10 and HLG. In this model, it was decided to abandon component video inputs and outputs, which simplified the placement of connectors on the rear panel. The device also has three analog and two digital inputs. Screw terminals are intended for connecting the front stereo acoustics, while spring terminals are used for the central, rear and side speakers. This is a completely acceptable solution in AV receivers of this price category.
At the same time, the Onkyo TX-SR494 is equipped with an automatic calibration system for ambient sound AccuEQ Room Calibration, which has not previously been found in models of this price. The device is equipped with decoders for HD surround sound formats and high-quality modern DACs from Burr Brown. There is a flexible crossover setting for the subwoofer, tone controls in the low and high frequency range, as well as Bluetooth for connecting mobile devices. You can monitor the Onkyo TX-SR494’s operation using the informative front-panel display or the user-friendly on-screen graphics. The new on-screen display shows you audio and video data, including HDR format, video resolution, frame rate, and audio codec, attached to the incoming signal.
The power amplifiers in the AV receiver are made on discrete components using the proprietary WRAT technology and are capable of handling even complex acoustic systems. The device has a completely universal sound character for listening to music of various genres, and when watching movies, it is capable of accurately conveying the most energetic special effects.
