The D-3500 from Samson is a digital, dual 15-band parametric EQ/feedback management system. For ease of use, the unit features Automatic Frequency Restoration (AFR) technology. If feedback spikes on any of the thirty filters, that frequency is cut. AFR continues to monitor that frequency and if the feedback goes away, the frequency is restored.
For more advance use the D-3500 provides multiple filter settings, programmable delay, high and low pass filters, a gate, limiter and more. 24-bit audio resolution and sample rates up to 96kHz provide for pristine sound and setting can be stored in 100 locations. The unit is linkable via MIDI or Samson's D-Net System interface.
