The EQ 230 combines two 30 bands single channel graphic equalisers, two fully parametric equahisation points and a feedback finder system (FFS). Unlike other automatic feedback destruction systems, the FFS is a simple feedback finder which allows the operator to eliminate feedbacks while monitoring, evaluating at the same time the overall effect produced by the equialisation on the signal.

FEATURES

Continuous variable high pass filter (10-300Hz) in order to delimit andwidth (this filter is of great utility when mixing string instruments, voices and to control low frequency feedback)

• BALANCED: Equipped with electronically balanced input and output circuits for noise inmmunity in long cabling set-ups.
• CONSTANT Q: The constant Q topology assures minimum interaction between bands and makes the bandwidth of each filter independent of the garnlattenuation setting.
• RANGE: Global selection of the range of gainlattenuation of each band for a more precise adjustment.Front panel indication by double LED.
• FFS: Feedback finder system (only EQ-230).A microprocessor associated with each channel scans the whole spectrum in order to detect and display possible feedbacks.Direct LED indicator on each fader.
• PARAMETRIC: Incorporates a totally parametric equalization point on each channel (only EQ-230).The range is asymmetric (± 15 dB-30 dB) allowing notch filter adjustments.
• LOW NOISE: The use of very low noise circuits and other techniques permit achieving an exceptional dinamic range.
• AUTO-BYPASS: Incorporates secure by-pass circuits controlled by relay to eliminate on/off switchs transients and for signal integrity in case of intemal failures.
