yamaha tsr-700 av-4 optical in or out

2 min read 24-01-2025

The Yamaha TSR-700 is a popular AV receiver known for its versatility. One aspect that sometimes causes confusion is its optical audio inputs and outputs. This article will clarify how the optical (Toslink) connections on the Yamaha TSR-700 work, their uses, and some common troubleshooting tips.

Optical Audio In on the Yamaha TSR-700

The Yamaha TSR-700 typically features one or more optical digital audio inputs (often labeled "OPT"). These inputs are designed to receive digital audio signals from various sources. This is crucial for high-quality audio transfer, preserving the signal's integrity.

Common Uses for Optical In:

Blu-ray Players: Connect your Blu-ray player to enjoy high-definition audio formats like Dolby Digital and DTS. This ensures the best possible sound quality from your discs.
Streaming Devices: Many streaming devices (like Roku, Apple TV, Fire TV) output digital audio via optical. Connecting this way often bypasses the lower-quality audio processing within the streaming device.
Gaming Consoles: Modern gaming consoles, such as the PlayStation and Xbox, can output audio digitally via optical for surround sound. The quality is generally better than using HDMI for audio.
CD Players (with digital output): Some CD players offer a digital optical output. Using this preserves the integrity of the audio signal.

Important Note: The optical input on the TSR-700 receives digital audio only. It cannot accept analog audio signals.

Optical Audio Out on the Yamaha TSR-700

The TSR-700 may also have an optical digital audio output (again, typically labeled "OPT"). This output sends the processed audio signal from the receiver to another device.

Common Uses for Optical Out:

External Subwoofer: Some subwoofers accept digital audio via optical. This can improve the quality of bass reproduction.
Digital-to-Analog Converters (DACs): If you use a high-end DAC, this is a great way to send the digital audio signal to it for converting into analog and connecting to your amplifiers.
Multi-room Audio Systems: Send audio to another room's sound system via an additional amplifier and speakers. This will output the selected source from the TSR-700's audio output.

Important Note: The signal sent from the optical out will reflect the audio processing done by the TSR-700. If you're using surround sound, that will be sent through the optical output.

Troubleshooting Your Yamaha TSR-700 Optical Connections

If you're having trouble with your optical audio connections, here are some common issues and solutions:

No Sound: Double-check all connections, ensuring the optical cables are securely plugged into both the source and the receiver. Make sure the correct input/output is selected on both devices.
Poor Sound Quality: A damaged optical cable is a likely culprit. Try a new cable to rule this out.
Incorrect Input Selection: Ensure the correct input on your Yamaha TSR-700 is selected to match the device connected to the optical input.
Signal Issues: If using a longer cable, signal loss can occur. Use a high-quality, shorter cable if possible.

Yamaha TSR-700 Optical In/Out: Conclusion

The optical inputs and outputs on your Yamaha TSR-700 provide flexibility for connecting various audio sources and devices. Understanding their functionality is key to getting the best possible sound from your home theater setup. Remember to always check your connections and device settings to resolve any audio issues you may encounter. For more in-depth troubleshooting, consult the Yamaha TSR-700's owner's manual.
