      Amplifier

      Yamaha RX-A830 Yamaha RX-A840

      7 channel Amplifier: Yamaha RX-A830 features 7 channel power amplifier. It is rated at 100 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      7 channel Amplifier: Yamaha RX-A840 features 7 channel power amplifier. It is rated at 100 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

        Speaker Configurations

        Yamaha RX-A830's and Yamaha RX-A840's amplifiers can be assigned for different speaker configurations.

        • Configurations: Available configurations are:
        • Yamaha RX-A830: 5.2, 7.2 with internal amplifier.
        • Yamaha RX-A840: 5.2, 7.2 with internal amplifier.
        • 2-ch Bi-Amp: Both models are able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

          • Sound Processing

          • Adaptive DRC: Yamaha RX-A830 and Yamaha RX-A840 feature Adaptive DRC (Dynamic Range Control) which automatically adjusts the dynamic range of the sound according to the volume level. This ensures that you hear clear dialog and vocals, and all sound effects at comfortable levels. There is no need to adjust the volume level as you listen; everything from whispers to big explosions will be heard clearly and comfortably at the same volume setting. It also tones down loud TV commercials, and is ideal for low-volume, late-night listening, when you do not want to disturb others.
          • Compressed Music Enhancer: Yamaha RX-A830 and Yamaha RX-A840 feature Compressed Music Enhancer which enhances the quality of the music files with lossy compression.

          Room Calibration

          Yamaha RX-A830 and Yamaha RX-A840 come with YPAO (R.S.C. with Multipoint measurement) room correction system.

          • YPAO: The Yamaha Parametric room Acoustic Optimizer (YPAO) function detects speaker connections, measures the distances from them to your listening position(s), and then automatically optimizes the speaker settings, such as volume balance and acoustic parameters, to suit your room.

        Video Section

        HDMI

        Yamaha RX-A830 and Yamaha RX-A840 come with 8 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

        • 4K/30Hz Passthrough on Yamaha RX-A830: All inputs pass up to 4K/30p video signal.
          4K/60Hz Passthrough on Yamaha RX-A840: All inputs pass up to 4K/60p (YCbCr 4:4:4) video signal.
        • 4K Upscaling on Yamaha RX-A830: It can upscale up to 4K/30p from HDMI and analog sources.
          4K Upscaling on Yamaha RX-A840: It can upscale up to 4K/60p (YCbCr 4:4:4) from HDMI and analog sources.
        • Analog To HDMI Upconversion: Both receivers support analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
        • HDCP 2.2.0 Copy Protection: Both receivers are HDCP 2.2.0 compliant which is a requirement for 4K/HDR copy-protected content transmission.
        • 3D Ready: Both receivers are able to pass 3D video through HDMI.

        Inputs and Outputs

        Audio

        • Phono Input: There is an MM phono input on Yamaha RX-A830 and Yamaha RX-A840 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Yamaha RX-A830 and Yamaha RX-A840 have 7.2 preamplifier outputs which allow you to connect the receivers to the external power amplifiers. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the receiver to power the rest. Also, both receivers have 7 channel processing but have only 7 channel amplifiers, so they need external amplifiers connected to the analog pre-outs in order to reach their maximum speaker configurations.
        • Analog Line Inputs and Outputs: There are 5 pair of line inputs on both receivers for connecting sources with analog outputs. There are also 1 pair of line outputs on the receivers.
        • Digital Inputs: 2 optical inputs and 2 coaxial inputs are available for digital audio connections on both receivers.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
