EATURES - handles high input levels (up to 100 m VRMS) cleanly - low THD and IMD distortion - unique twin average detectors - dual channel signal processing - - - - adjustable AGC threshold levels highpass filter with adjustable corner frequency 2:1 pression of high frequencies no external capacitors or resistors required DESCRIPTION The Dynam EQ ® I hybrid is a dynamically adaptive loudness growth equalizer. Its gain and frequency response is dependent on the user's environment, and is designed for level dependant frequency response providing treble increase at low levels (TILL). The unique twin averaging detector circuit dramatically reduces pumping effects and is optimized for mild to moderate hearing loss. Dynam EQ® I has two signal paths for dual channel processing incorporating 4 amplifying stages ( A, B, C, D ) and the AGC processing circuit. Stage A is a highpass channel with 2:1 pression, Stage B is a wideband unity gain buffer. The sum of the two paths gives a high frequency boost to low level signals, which gradually presses to a flat response at high input levels. Stage C is used for volume control adjustment, while stage D is a class A power amplifier with receiver bias current adjustment. - 30% smaller by volume than Dynam EQ® I GS3011 STANDARD PACKAGING - Hybrid Typical Dimensions 0.250 in x 0.115 in x 0.115 in (6.35 mm x 2.92 mm x 2.92 mm) C7 2µ2 C6 0µ1 100k VREG 10 C1 2µ2 RTH 1 R1 68k CHP 11 C2 IN 100k FAST AVERAGE DETECTOR REGULATOR SLOW AVERAGE DETECTOR CURRENT REFERENCE 2:1 PRESSION CONTROL RECTIFIER VB 24k 12k -A 3n9 -C 2 RE 11 C3 0µ1 MGND 8 R2 50k -B 50k 50k 50k 1k GND 4 C4 0µ1 C5 0µ1...
