Thank you for viewing. This is a de-esser, popular with plugins and more. I am selling it to organize my equipment. It works perfectly fine, and I have no issues using it. Please feel free to ask any questions in the comments. This is an older model that is no longer sold, so I think it's a pretty rare listing. I will add more photos later. This is a 2-channel analog de-esser, perfect for audio processing. - Model: DE-ESSER - Brand: SPL - Function: De-esser - Number of channels: 2 - Controls: Analog knobs - Indicators: LED indicators
