The SENSITIVITY switch on the LYD is designed to adjust the input to align with the level of the incoming audio signal. The available settings indicate whether the signal will be amplified (gain) or reduced (attenuation).
Properly setting the sensitivity is crucial to prevent two common issues: overdriving the input stage, which can lead to distortion and artifacts, and setting the level too low, which may introduce unwanted background noise. Overdriving can also pose a risk of damaging the electronics or drivers.
To determine the appropriate sensitivity setting for your LYD, follow these steps:
1. Review the specifications of your audio source (such as an interface, mixer, or speaker controller) to find the maximum analog output level. This information is typically provided in dBu or volts.
If you're unsure how to locate these specifications, don't hesitate to contact the manufacturer for assistance, or reach out to us for help.
2. Adjust the LYD sensitivity switch to correspond with the output level you found. The settings are as follows:
▪ +6dB = 0dBu / 0.775V max
▪ 0dB = +6dBu / 1.5V max
▪ -6dB = +12dBu / 3.1V max
For most audio interfaces available today, the recommended setting is -6dB.
Please note: Many interfaces might indicate a maximum output level around +20, +24, or even +27 dBu. In such cases, you should set the sensitivity switch to -6 dB. It is important to keep a close eye on your levels and ensure you have adequate headroom to avoid distortion, especially when the output volume is managed solely in the digital domain.
For example, if your interface outputs a maximum of +18 dBu at 0 dBFS, ensure that your monitoring levels (as indicated in the interface control panel meters) do not surpass -6 dBFS.
If your source volume knob or fader adjusts the analog level after the digital-to-analog converter (DAC) in the interface, make sure that your maximum output level does not exceed +12 dBu.
