How to connect Marantz receiver to Samsung TV
If you want better dialogue clarity, surround sound, and fewer TV speaker limitations, connecting a Marantz receiver to a Samsung TV is the upgrade that matters.
The right setup depends on whether your model supports HDMI ARC, eARC, or only optical audio, and a few menu settings can make the difference between instant success and no sound at all.
Marantz AV receivers and Samsung Smart TVs work well together, but the connection process is not always obvious because audio routing, HDMI input selection, and CEC control must all align.
This guide explains the best connection methods, how to configure both devices, and how to fix the most common problems.
What you need before you start
Before connecting anything, confirm the inputs and outputs on both devices.
Most modern Marantz receivers include HDMI ports labeled ARC or eARC-compatible, while many Samsung TVs include a dedicated HDMI port marked ARC or eARC on the back.
- A Marantz AV receiver with HDMI inputs and an HDMI monitor output
- A Samsung TV with HDMI ARC or eARC support
- A high-speed HDMI cable, ideally certified for HDMI 2.0 or HDMI 2.1
- An optical digital cable if HDMI ARC is not available
- The remote controls for both devices
If you are using external devices such as a cable box, Apple TV, PlayStation 5, Xbox Series X, or a Blu-ray player, you may also want to connect those sources to the receiver instead of the TV.
That routing often gives the Marantz receiver direct control over audio decoding and can simplify the setup.
Best method: connect with HDMI ARC or eARC
HDMI ARC, or Audio Return Channel, sends audio from the Samsung TV back to the Marantz receiver over the same HDMI cable used for video. eARC, or enhanced ARC, supports higher-bandwidth formats and is the better choice if both devices support it.
How to connect the cables
- Turn off both the Samsung TV and the Marantz receiver.
- Connect one end of the HDMI cable to the TV’s HDMI port labeled ARC or eARC.
- Connect the other end to the Marantz receiver’s HDMI OUT port labeled ARC, TV, or MONITOR OUT, depending on the model.
- Power on the TV and receiver.
On many Marantz models, the receiver’s HDMI output is the only port used for the TV connection.
All source devices connect to the receiver’s HDMI inputs, while the TV acts as the display and audio return device.
Enable Samsung TV audio settings
Once the cable is connected, open the Samsung TV settings and confirm that audio output is set correctly.
The exact menu path varies by model, but the setting is usually under Sound or Expert Settings.
- Set Sound Output to Receiver (HDMI) or HDMI ARC/eARC
- Turn on Anynet+ (HDMI-CEC)
- If available, set eARC Mode to Auto
- Set Digital Output Audio Format to Auto or Pass-Through when supported
Anynet+ is Samsung’s HDMI-CEC feature.
It allows the TV and receiver to communicate for power, volume, and input switching.
Without it, ARC often fails to behave properly.
Enable Marantz receiver settings
On the Marantz receiver, check the HDMI and control settings.
Menu names vary by generation, but the important features are similar.
- Set HDMI Control to On
- Set ARC to On
- Set TV Audio Switching or similar control features to On if available
- Confirm the receiver input is set to the TV audio source when you want sound from the TV apps
Some Marantz models require a restart after changing HDMI Control or ARC settings.
If audio does not start immediately, power cycle both devices after saving the changes.
How to connect a Marantz receiver to a Samsung TV without ARC
If your Samsung TV or Marantz receiver does not support ARC, the next-best option is optical digital audio.
This method carries stereo and multichannel compressed audio, but it does not support advanced formats like Dolby TrueHD or uncompressed Dolby Atmos over ARC.
Optical connection steps
- Connect one end of an optical cable to the TV’s Digital Audio Out port.
- Connect the other end to the Marantz receiver’s Optical In port.
- Set the TV sound output to Optical or External Speaker.
- Set the receiver input to the matching optical source.
Optical audio is reliable for basic TV sound, streaming apps, and broadcast television.
It is also helpful if your HDMI ARC port is occupied or unstable.
Should you connect source devices to the receiver or the TV?
For the best audio experience, connect source devices directly to the Marantz receiver whenever possible.
The receiver can decode formats such as Dolby Digital, DTS, Dolby Atmos, and DTS:X depending on the source and model support, then send video to the Samsung TV through a single HDMI output.
This approach is especially useful for:
- 4K Blu-ray players
- Gaming consoles
- Streaming boxes
- Cable and satellite receivers
Using the receiver as the central hub reduces audio handshake issues and often improves lip-sync control.
The Samsung TV still handles the display, while the Marantz receiver handles surround sound processing.
Common reasons there is no sound
If the connection is correct but no audio plays, the issue is usually a setting mismatch rather than hardware failure.
Check these common causes first.
- Wrong HDMI port on the TV: only the ARC/eARC-labeled port will work for return audio
- HDMI Control is off on the receiver
- Anynet+ is disabled on the Samsung TV
- The TV is still sending audio to its internal speakers
- The receiver is on the wrong input
- The HDMI cable is damaged or not rated well enough
- The TV needs a full power cycle after a settings change
If you recently changed cables, inputs, or firmware, disconnect power from both devices for about 60 seconds.
That resets the HDMI handshake and often restores communication.
How to fix audio delay or lip-sync problems
Audio delay is common when video processing and sound processing are not aligned.
Samsung TVs and Marantz receivers both offer ways to adjust timing.
- Check the Marantz audio delay or lip-sync setting
- Disable unnecessary TV picture processing such as motion smoothing if latency is noticeable
- Use eARC when available, since it can provide more consistent synchronization
- Make sure source devices are not also applying their own audio delay
If you are watching content through built-in Samsung TV apps such as Netflix, Disney+, Hulu, or YouTube, the TV may be adding processing time before sending audio to the receiver.
A small delay adjustment in the Marantz menu usually corrects this.
Can a Marantz receiver control Samsung TV volume and power?
Yes, if HDMI-CEC is enabled on both devices.
On Samsung TVs this is called Anynet+, and on Marantz receivers it is usually part of HDMI Control.
Once enabled, you can often power both devices on with one remote and adjust volume through the receiver.
Control features can vary by model, but typical benefits include:
- Single-remote volume control
- Automatic input switching
- Power sync between TV and receiver
- TV audio switching to the receiver when the TV turns on
If the TV keeps switching away from the receiver or the volume controls do not respond, disable CEC on both devices, reboot them, then turn the feature back on in the correct order.
When to use eARC instead of ARC
Choose eARC if both the Samsung TV and Marantz receiver support it. eARC provides more bandwidth, better format support, and fewer compatibility limits than standard ARC.
It is especially useful for high-quality streaming audio and newer TV platforms.
eARC is the better option for users who want:
- Higher-quality uncompressed audio support
- More reliable passthrough from modern smart TV apps
- Better compatibility with advanced sound formats
Even with eARC, the HDMI cable still matters.
Use a certified high-speed cable that is in good condition and connected to the correct ports on both devices.
Quick setup checklist
- Connect the Samsung TV ARC or eARC port to the Marantz HDMI OUT port
- Enable Anynet+ on the Samsung TV
- Enable HDMI Control and ARC on the Marantz receiver
- Set TV audio output to Receiver or HDMI ARC/eARC
- Use source devices on the receiver’s HDMI inputs when possible
- Restart both devices after changing settings
Once these steps are in place, the Marantz receiver should handle TV sound with minimal effort, giving you cleaner dialogue, stronger bass, and a more immersive home theater experience.
