D6573 Feedback Suppressor

Features:

● 24-bit A/D and D/A conversion, high resolution.
● Each track allows automatic search for 12 frequency feedback, intelligent processing.
● Prompt and easy default processing and complete feedback suppression performance.
● In single-point mode, the device will automatically search for and lock notch frequency until the device is manually reset or reconfigured.
● In manual mode, the user can set all parameters of 2×12 filters, including their frequency and Q value, etc.
● Servo balanced input and output, gold plated XLR and TRS terminals.
● Two modes (SING and AUTO) available on each filter.
● Two parallel processing modules, the left and right channel may be adjusted independently or in parallel.
● 24-bit high-performance DSP, ensuring signal resolution and dynamic range.

  • Connection

D6573 is a digital automatic feedback suppressor with high performance price ratio. The device allows storage of 10 groups of data for needs of tone quality control in 10 different scenarios. During suppression process the attenuation range may be as low as -48dB. When feedback is detected, the local device will quickly and automatically analyze and lock the feedback frequency by using its advanced DSP algorithm and determine the frequency point, frequency bandwidth and attenuation of the notching filter, and will save the processing results.Since the device is able to control the frequency bandwidth of notching filter, only feedback signal is filtered,without damages to the music signal and with very high acoustic fidelity.
