Technical Specications

Ultra-Fast and Fully Automatic Dual-Channel Feedback Suppression Processor

TN6232

The automatic feedback suppressor shall be a dual-channel digital signal processor with thirty-two (32) 1/30th octave lters

per channel. The lters shall be of the processor-controlled variable Q type (lter skirts narrow and widen at the discretion of

the processor).

The device may be used on selected insert points, sub-groups, monitor feeds, or the entire mix. It shall detect feedback,

determine the oending frequency, and then assign a notch lter to eliminate the feedback automatically. The device

shall continue to provide this function throughout the program or performance, andshall use dynamic notch lters,

whichwill be automatically assigned to new frequencies should feedback occur during the program. The unit shall include:

anActive/Bypass button with an LED indicator for each mode of operation, allowing the user to set the unit to control

feedback (activemode) or remove the device from the signal path (bypass mode); and a Filter Reset button with LED

indicator, so all lters may be re-congured.

The product shall be equipped with a rear-mounted power switch, an power socket congured to operate at 115 VAC,

balanced and unbalanced inputs on 3-pin Euroblock and combination ¼" TRS / XLR-3 connectors, with balanced and

unbalanced outputs on both 3-pin Euroblock and XLR connectors. The automatic feedback controller shall be the EUROCOM

TN6232 Feedback Suppressor.
