Alto Professional | TX3 Series Troubleshooting Audio Issues
Modified on: Thu, 26 Oct, 2023 at 6:39 AM
Poor Audio Quality from my Phone, Laptop or smart device
TX3 features an XLR Mono Audio Input – Connecting a stereo source to a mono input can result in phase cancellation which causes poor audio quality symptoms and the loss of Mono captured audio (vocals, kick drums, bass and more).
If you own two TX3 speakers, connect a Y-Split XLR cable from your sound source to each speaker. This creates a specified feed for your Left & Right audio channels to provide a stereo image.
If you own only one TX3 speaker, many smart devices feature the option to transmit audio in Mono – In such cases, please refer to the documentation for your sound source / device to send audio in Mono.
Poor audio quality – Crackling / Distortion
If you notice distortion or crackling audio, turn down the audio level of your sound source – The rear of your speaker features a signal limit LED. This will illuminate RED if your incoming signal is too high, resulting in clipping; prolonged exposure of clipping can cause damage to your speakers more delicate components such as the Tweeter & Woofer.
When the Signal LED appears GREEN, this confirms your signal is healthy. If you are still experiencing symptoms of Crackling / Distortion, try a different audio source and different XLR audio cables; if you’re using a connection adapter (e.g. ¼” > XLR), try using a different adapter or a direct cable type.
Will Not Power On
If TX3 is failing to power on, try using a different IEC power cable. This is a generic cable type you may have in your home, it also has a nickname called a ‘kettle lead’.
If power issues continue to persist, replace the fuse.
Fuse specifications: 100–120V T6.3AL AC250V or 220–240V T3.15AL AC250V
Note: TX3 is region fixed and not suitable for power outside of the region purchased.
