Audio clipping happens when the audio is too loud or powerful for the audio equipment to reproduce accurately.
The amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability. When clipping occurs, the amplifier will amplify the signal only up to its maximum capacity.
When audio clipping happens while someone speaks into a microphone, the audio sounds distorted or harsh. In traditional systems, you might see a gain indicator light turning red on an audio mixer when clipping is audible.
Avoid audio clipping with the Hub DSP receiver:
- Automatic processing: Hub's built-in DSP automatically manages audio levels reducing the risk of clipping without manual intervention.
- Wide dynamic range: The system handles a wide range of voice levels without manual adjustments.
- Voice lift control: Instead of traditional gain control, use the voice lift level adjustment for mixed outputs to optimize overall volume while maintaining audio quality. For RCA and mixed 3-pin outputs you can fine-tune the voice lift level to balance audio amplification.
Adjusting Voice lift level on the Hub:
1. Access the Output settings in the Hub's interface.
2. Select the desired output (RCA or mixed 3-pin)
3. Locate the voice lift level control and adjust it.
If you still experience audio clipping
Check check the input routing in the Hub's interface to ensure all input sources are correctly routed and enabled. This is crucial for proper signal flow.
Next, review the mix configuration for each output, verifying which inputs are enabled. This step helps you understand and control what's being sent to each output.
If the audio seems too loud, adjust the Voice Lift Level for the mixed outputs.
For setups using external amplifiers or speakers, it's important to check and adjust their volume settings as well, as these can contribute to overall audio quality.
