DSPPA D6573 Manual

Description
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. The
major features of the device include: Refined frequency search, adjustable suppression width, and display of
parameters.
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.
 Soft start of switches, free of knocking sound, noise gating function.
 Backlight 2×16 character LCD.
 2×7 LED level display, capable of displaying input or output level.
 High-quality SMD components and automatic SMD welding and online testing technologies ensure high
quality and reliability of the product.
 Specialized internal power supply system.
