    USB-audio as an interface for computers. Tight AV DSP 1.0 is a Windows-based application used to configure and control the DSP hardware. An easy-to-use GUI gives the user fast access to all the available processing functions. The unit has 16 built-in presets that can store the complete configuration for later recall.

  • Page 6: Floating Point Dsp

    Audio DSP with AEC, 4-in/4-out analog, 4-in/4-out Dante and USB 1.5 Floating Point DSP The signal processing is done in an Analog Devices SHARC DSP, enabling 32-bit and 40-bit floating-point processing. Floating- point processing provides advantages for the users in terms of sound quality and usability. With floating point processing the internal calculations of the DSP will have higher dynamic range and avoid rounding errors that can be a cause of noise.

    Audio DSP with AEC, 4-in/4-out analog, 4-in/4-out Dante and USB Attack & Release Time: Refers to the time required to activate the compressor when the signal goes above the threshold. Output Gain: Used to compensate for the gain reduction in the compressor. G.R.

  • Page 16: Equalizers

    Audio DSP with AEC, 4-in/4-out analog, 4-in/4-out Dante and USB When the signal level is lower than the threshold, the input-to-output ratio is 1:1. When the Threshold: signal level is higher than the threshold, the input-to-output ratio changes with the ratio control settings. The threshold should be set just above the background noise level to avoid amplification of the noise.

  • Page 17: Feedback Filters

    Audio DSP with AEC, 4-in/4-out analog, 4-in/4-out Dante and USB 3.3.6 Feedback filters After setting proper levels for microphone and speakers, the feedback filter section can be used as a secondary precaution to avoid unwanted feedback. The traditional methods should still be used, such as limiting the number of open microphones, minimizing the distance between sound source and microphone, good distance between the microphone and loudspeakers, and equalizing the room speakers to get a flat response.

  • Page 18: Automixer

    Audio DSP with AEC, 4-in/4-out analog, 4-in/4-out Dante and USB Filter Mode: Each feedback filter has three modes: dynamic, manual and fixed. When manual mode is set, the gain can also be manually set. When Fixed mode is set, the filter always works and will not be occupied by new feedback points; it still works when being rebooted.
