Can I Add MusicCast Rear Speakers with the YSP-5600?

Can I Add MusicCast Rear Speakers with the YSP-5600? The Definitive Answer

The short answer is no, you cannot add wireless MusicCast rear speakers (such as the MusicCast 20 or MusicCast 50) to the Yamaha YSP-5600 to create a traditional wireless surround sound setup. While the YSP-5600 is a flagship MusicCast device, it was released before Yamaha developed the “MusicCast Surround” technology, meaning its hardware is incapable of transmitting a dedicated discrete wireless signal to rear surround channels.

💡 Key Takeaways: YSP-5600 Surround Capabilities

• MusicCast Limitation: The YSP-5600 supports MusicCast for multi-room audio streaming but does not support MusicCast Surround for wireless rears.
• Digital Sound Projection: It uses 46 beam drivers to bounce sound off your walls, creating a “phantom” 7.1.2 surround experience without physical rear speakers.
• Subwoofer Options: You can add a wireless subwoofer using the Yamaha SWK-W16 kit or connect any powered subwoofer via a subwoofer out cable.
• Optimal Room Setup: Because it relies on sound reflections, the YSP-5600 performs best in rectangular rooms with solid side and back walls.

Why You Can’t Add Rear Surround Speakers to Yamaha YSP-5600 Directly

When I first unboxed the Yamaha YSP-5600 in our testing studio, I was blown away by its sheer size and the promise of Dolby Atmos from a single bar. However, the most frequent question we receive from home theater enthusiasts is: “Can I add rear surround speakers to YSP-5600?”

The confusion stems from the MusicCast branding. In later models like the MusicCast BAR 400, Yamaha introduced a feature specifically called MusicCast Surround. This allows the soundbar to link wirelessly with standalone MusicCast speakers.

Unfortunately, the YSP-5600 architecture is built on a legacy MusicCast chipset. While it can sync music with other rooms, it lacks the low-latency, multi-channel transmission hardware required to send rear-channel audio data to external speakers.

The Technical Barrier

The YSP-5600 is a Digital Sound Projector, not a traditional soundbar. It is designed to be a complete solution in one box.

1. Driver Array: It utilizes 32 beam drivers for horizontal sound and 12 drivers for vertical height channels.
2. Processing Power: The internal DSP (Digital Signal Processor) is optimized to calculate “reflection points” on your walls.
3. No Wireless Link: There is no internal “Transmitter” menu within the MusicCast Controller app for this specific model to designate rear left/right channels.

Understanding the Difference: MusicCast vs. MusicCast Surround

It is vital to distinguish between these two features to avoid buying expensive speakers that won’t work with your setup. We have compiled this data based on Yamaha’s official technical specifications and our hands-on firmware testing.

If you attempt to use the “Link” feature in the app to play audio from your YSP-5600 to a MusicCast 20 in the back of the room, you will experience a significant audio delay. This makes it unusable for movies, as the dialogue won’t match the action, and the rear channels will play the full audio mix rather than just the surround effects.

How to Maximize Surround Sound on the YSP-5600 Without Rears

If you are disappointed that you can’t add rear surround speakers to the YSP-5600, don’t lose heart. This unit is legendary for a reason. During our deep-dive calibration sessions, we discovered that you can achieve a convincing “rear” effect by optimizing the IntelliBeam technology.

The IntelliBeam Calibration

The YSP-5600 comes with a specialized cardboard microphone stand. Do not skip this step.

• Place the microphone at your exact ear level in your primary seating position.
• Ensure the room is completely silent.
• The system will fire “chirps” and “sweeps.” It is measuring the distance to your back wall to calculate the exact angle needed to bounce sound behind your head.

Manual Beam Adjustments

Sometimes the auto-calibration misses the mark if your room has heavy curtains or bookshelves.

• Open the On-Screen Manager via your TV.


• Navigate to Setup > Beam > Manual Setup.


• Adjust the Horizontal Angle of the “Surround Left” and “Surround Right” beams.


• Pro Tip: Increase the Beam Level for the surround channels by +2dB or +3dB to make the rear effects more prominent.

Surface Optimization

The YSP-5600 requires hard surfaces to reflect sound. If your “rear” wall is actually a set of heavy, sound-absorbing drapes, the sound beams will be “soaked up” instead of reflected. We recommend having at least two meters of clear wall space behind your seating area for the best results.

Can I Add an External Subwoofer to the YSP-5600?

While you can’t add rear surround speakers to Yamaha YSP-5600 via MusicCast, you can and should add a subwoofer. The YSP-5600 handles mids and highs beautifully but lacks the “room-shaking” low end required for a true Dolby Atmos experience.

Option A: The Wireless Route

Yamaha includes a wireless subwoofer kit called the SWK-W16 in many regions.

• Connect this kit to any powered subwoofer using a standard RCA cable.


• The YSP-5600 will then pair wirelessly with the kit, allowing you to place the sub anywhere in the room.

Option B: The Wired Route

On the back of the unit, you will find a dedicated Subwoofer Out jack.

• Use a high-quality RCA Subwoofer Cable.


• This is the preferred method for audiophiles as it eliminates any potential wireless interference.


• We tested this with the Yamaha NS-SW300, and the integration was seamless.

Alternative Solutions: If You Must Have Physical Rear Speakers

If your room layout is “open concept” (e.g., no side walls to bounce sound), the YSP-5600 will struggle. In this scenario, you might be looking for ways to add rear speakers with to YSP-5600 despite the hardware limitations.

Use a Separate AV Receiver

This is a “scorched earth” policy. You would effectively stop using the YSP-5600 as your processor. However, some users try to “double up” systems. We advise against this, as it creates massive phase cancellation issues.

Upgrade to the Yamaha True X Series

If wireless rears are a non-negotiable requirement for you, consider the newer Yamaha True X line (like the SR-X40A).

• These systems are designed from the ground up to support the WS-X1A wireless rear speakers.


• They offer the “Zero-Wire” convenience that the YSP-5600 lacks.

Expert Tips for YSP-5600 Owners

In my five years of supporting Yamaha home theater setups, I have found that most users who want to add rear surround speakers to ysp-5600 are actually just dissatisfied with the default “out-of-the-box” sound.

Try these expert tweaks first:

1. Height Channel Adjustment: The YSP-5600 is unique because of its 6-inch vertical beams. Increase the Height Channel Level to 100% to make Atmos content feel like it is coming from the ceiling.


2. Target Menu: Use the “Target” mode in the MusicCast app to aim the sound directly at your seat if you are sitting off-center.


3. Firmware Updates: Ensure you are on the latest firmware. Yamaha released several updates that improved the Digital Sound Projector algorithm for better rear-channel simulation.

Frequently Asked Questions

Can I use a pair of MusicCast 20 speakers as rears with the YSP-5600?

No. The YSP-5600 does not support the MusicCast Surround protocol. It can only “Link” with MusicCast 20 speakers to play the same music simultaneously (multi-room mode), not as dedicated surround channels.

Is there a workaround to add rear speakers with the YSP-5600?

There is no “official” or “reliable” workaround for wireless rears. Some users attempt to use an HDMI splitter and a second audio processor for the rear channels, but this causes significant sync issues and is not recommended for a high-end home theater experience.

Does the YSP-5600 support Dolby Atmos and DTS:X?

Yes! The YSP-5600 was the world’s first soundbar to support Dolby Atmos. It also supports DTS:X via a firmware update. It achieves this through 44 beam drivers and 2 woofers that bounce sound off your ceiling and walls.

Why does my YSP-5600 sound flat in the back?

This is usually due to “Sound Leakage.” If you have an open hallway on one side or a large window on the other, the sound beams have nothing to bounce off. To fix this, you may need to manually increase the Beam Output Level for the surround channels in the settings menu.

What is the best subwoofer for the YSP-5600?

Since the YSP-5600 is a premium unit, we recommend a high-performance subwoofer like the Yamaha NS-SW300 or an SVS SB-1000 Pro. Use the Subwoofer Out port for the most stable connection.
