The Audio-Technica AT-LP120 is a popular and well-regarded turntable among vinyl enthusiasts. However, like any electronic device, it can encounter issues over time. One common problem that users might face is the turntable only playing sound through one speaker. This can be frustrating and impact the listening experience. In this article, we will explore potential reasons behind this issue and provide practical troubleshooting steps to help you resolve it.
1. Check the RCA Cables
The most common reason for sound coming through only one speaker is a problem with the RCA cables. The Audio-Technica LP120 uses RCA cables to connect to the audio system. Ensure that both the left (white) and right (red) RCA cables are securely plugged into the corresponding inputs on the turntable and the audio system.
2. Swap the RCA Cables
To determine if the issue is with the cables or the turntable, swap the left and right RCA cables at both ends (turntable and audio system). If the problem persists but switches to the other speaker, it indicates a problem with the cables. Replace the faulty RCA cables with new ones to restore stereo playback.
3. Check the Cartridge and Stylus
A misaligned cartridge or a damaged stylus can also cause sound to be played through only one speaker. Check that the cartridge is securely mounted and aligned correctly on the tonearm. Inspect the stylus for any signs of wear or damage. A worn-out or damaged stylus can result in audio being played through only one channel. If the stylus is worn, replace it with a new one to restore proper playback.
4. Balance Control on Audio System
Check the balance control on your audio system. If it is set to one extreme, it may cause the sound to be biased towards one speaker. Ensure that the balance control is centered or set to an equal balance between the left and right channels.
5. Clean the Contacts
Dust and dirt can accumulate on the RCA plugs and other contacts, leading to connectivity problems and imbalanced sound. Disconnect the RCA cables from the turntable and the audio system, and clean the plugs using contact cleaner or isopropyl alcohol. Additionally, clean the RCA input jacks on the audio system.
6. Test with Different Records
Sometimes, the issue may be with the recording itself rather than the turntable. Test the turntable with various records to determine if the problem persists across different recordings.
7. Check the Phono Preamp
If your turntable requires a phono preamp to boost the signal before connecting to the audio system, check if it is functioning correctly. A malfunctioning phono preamp can cause audio to be played through only one speaker. Try using a different phono preamp or connect the turntable directly to the audio system to check for any differences in sound.
Conclusion
Experiencing sound playing through only one speaker on your Audio-Technica LP120 can be concerning, but with careful troubleshooting, it is often possible to identify and resolve the problem. By checking the RCA cables, cartridge, stylus, balance control, and phono preamp, you can address most common causes of audio only playing through one speaker. Regular maintenance and proper care of your turntable will ensure exceptional sound quality and protect your cherished vinyl collection. If the issue persists despite your efforts, do not hesitate to seek professional assistance from an experienced turntable technician to diagnose and address any mechanical or electrical problems. With the right care and attention, your Audio-Technica LP120 will continue to provide an enjoyable stereo experience for years to come.
