Yes, there are devices available that can help you introduce an adjustable delay to synchronize the audio between two sets of speakers and eliminate the echo. Such devices are commonly known as "audio delay processors" or "audio delay units." They are designed to address issues like sound synchronization in situations where there is a noticeable delay between audio sources or when daisy-chaining multiple speakers.
An audio delay processor typically has inputs and outputs that support various audio connections, including 3.5mm connections (also known as AUX or headphone jacks). You can connect your audio source (e.g., a music player, TV, or computer) to the input of the delay processor, and then connect one set of speakers to the processor's output. The other set of speakers can be connected directly to the original audio source or through another output of the delay processor.
The key feature of these devices is the adjustable delay, which allows you to fine-tune the timing of the audio output to match both sets of speakers. By doing so, you can eliminate any perceptible echo or audio misalignment between the speakers.
When choosing an audio delay processor, consider the following factors:
Delay Range: Make sure the device offers a sufficient range of delay adjustments to meet your specific needs.
Audio Connections: Ensure that the delay processor supports the audio connections you need (e.g., 3.5mm, RCA, XLR, etc.).
Audio Quality: Look for a device with good audio quality to maintain the integrity of your sound.
Ease of Use: Choose a device that is user-friendly and allows for easy adjustment of the delay settings.
Power Source: Check whether the delay processor requires batteries or external power to operate.
Reviews and Recommendations: Read reviews and seek recommendations from others who may have used delay processors for similar purposes.
Keep in mind that while an audio delay processor can help synchronize audio between speakers, it cannot correct issues caused by significant differences in speaker characteristics or room acoustics. In some cases, an audio delay processor may not fully resolve the echo if other factors are contributing to the problem. In such cases, additional adjustments to speaker placement or room treatment may be necessary.
Before purchasing an audio delay processor, you may want to consult with an audio expert or professional to ensure it's the right solution for your specific setup and requirements.
