Yamaha MusicCast 50 WX-051 Wireless Speaker

Yamaha MusicCast 50 WX-051 wireless speaker is an active, freestanding two-way stereo system with a built-in network player. It is designed for music listening, multiroom audio and compatible wireless surround sound configurations.

The integrated Class D amplifier delivers a maximum output of 2 × 35 W. Two 10 cm woofers and two 3 cm tweeters reproduce both stereo channels from a single enclosure.

Applications and system expansion

A single speaker does not require a separate power amplifier, so it can operate as a self-contained network audio system. For clearly separated left and right channels, MusicCast Stereo mode requires two MusicCast 50 speakers.

In a home cinema system, the speaker can serve as a wireless rear speaker. MusicCast Surround works only with selected compatible Yamaha MusicCast AV receivers and soundbars.

Connections and audio sources

The Wi-Fi 802.11 b/g/n connection supports network playback, internet radio and the MusicCast multiroom system. Bluetooth 4.2 + EDR is suitable for streaming audio directly from a phone or another compatible device. Supported Bluetooth profiles are A2DP and AVRCP, with SBC and AAC codec support.

AirPlay enables audio streaming from compatible Apple devices. The specific AirPlay version is not stated. High-resolution audio support is listed without specifying formats, sampling rates or bit depths.

The analogue RCA connection is useful for connecting a wired audio source. A turntable must have a built-in phono preamplifier, or a separate phono preamplifier must be placed between the turntable and the RCA input.

Television audio can also be played through the speaker, although the precise connection method is not specified. The required cable must be selected according to the television’s audio output and the connections available on the speaker.

Control and everyday use

The free MusicCast app for Android and iOS devices controls playback and connected MusicCast products. Touch-sensitive controls and playback presets provide direct access to frequently used listening options. Alarm functions are also integrated.

Internet radio and Spotify support were provided as network features. Availability may depend on the region, software, changes made to the relevant services and continued platform support.

Alexa voice-control compatibility varies by region. This function requires the relevant service and a compatible system configuration.

Placement

The 400 mm-wide enclosure requires a sufficiently large, level surface. Its 200 mm depth should be considered when choosing a shelf, cabinet or another installation position. A stable support is required for the speaker’s 4.5 kg weight.

For a stereo pair, the two speakers should ideally be placed at a similar height and at symmetrical distances from the listening position. When MusicCast Surround is used, the audio signal is transmitted wirelessly. The active rear speakers still require mains power.

FAQ

Does this speaker require a separate amplifier?

No. Its integrated Class D amplifier allows the speaker to be used without a separate power amplifier.

How do I connect a turntable?

A turntable can be connected to the RCA input. It must have a built-in phono preamplifier, or a separate phono preamplifier must be connected between the turntable and the speaker.

Is one speaker sufficient for stereo sound?

One speaker reproduces a stereo signal through its integrated drivers. For wider separation between the left and right channels, two MusicCast 50 units can be paired.

Can it be used as a wireless rear home cinema speaker?

Yes, but only with selected Yamaha AV receivers or soundbars that support MusicCast Surround.

When should I use Wi-Fi, and when should I use Bluetooth?

Choose Wi-Fi for the MusicCast network and multiroom playback. Bluetooth is convenient for direct playback from a single nearby device.

What should I consider when choosing a placement location?

Allow at least 400 mm of width and 200 mm of depth. The surface must be stable enough to support the 4.5 kg speaker.
