Yamaha expands its AV amplifier range with the RX300A and RX500A models

RX300A serves as the more affordable option in the lineup. It has a 5.2-channel structure, five amplifier channels and two subwoofer pre-outs. For Dolby Atmos use, the amplifier also supports flexible speaker layouts, where surround sound can be implemented either with virtual height effects or with ceiling speakers and upward-firing speakers. According to the RX300A product information, the power is stated as 70 watts per channel when driving two channels into an eight-ohm load.

RX500A takes things a step further with a 7.2-channel structure. It can be used to build, for example, a 5.2.2 speaker layout, which also includes height channels. In addition to Dolby Atmos, the RX500A supports DTS:X surround sound, and its wider format support is also reflected in features such as DTS-HD Master Audio and DTS Neural:X.

The clearest practical difference between the models, however, is in streaming. In the RX300A, wireless playback is based on Bluetooth 5.3 Multipoint, which allows you to pair two devices and switch between them. The RX500A adds Wi-Fi and Ethernet connections, as well as support for Spotify Connect, Google Cast, AirPlay 2, Tidal Connect, Qobuz Connect, internet radio and podcasts.

Both new products have four HDMI inputs and one HDMI output. HDMI eARC allows the TV's audio to be returned to the amplifier with a single cable, making it easier to connect current smart TVs, game consoles, and streaming devices to the same system.

In addition to HDMI, the connections include two analog RCA inputs, one optical digital input, one coaxial digital input, a headphone output, a USB connection, and an FM radio. According to the product information, an AM radio is not included. Both models also have Scene buttons, which can be used to store four different usage situations, for example, for movies, music, or evening use.

Yamaha has emphasized ease of setup with its new products. The included microphone measures the room's acoustics and speaker configuration, after which the amplifier automatically optimizes playback. The goal is to make it easier to set up a home theater without the user needing to know all the technical details of surround sound.

On-screen menus and a Quick Guide walk you through connecting speakers, a TV, and external devices, as well as selecting inputs. Sound modes include Pure Direct, Straight, Movie, All Channel Stereo, 2 Channel Stereo, Music, and Night.

According to the press release, the models have been designed using Yamaha's long experience in AV amplifiers. The company refers to the DSP-1 model, which was introduced in 1986, and after which home theater audio has been developed for almost four decades. The new models emphasize the importance of signal paths, component placement and HDMI circuit cooling, among other things.

Both models also feature Yamaha's ART Wedge, a fifth leg placed in the center of the device that is designed to dampen frame vibrations and support more accurate sound reproduction. A feature previously seen in Yamaha's more expensive AV amplifiers.
