The AEC input card provides four channels of transparent Acoustic Echo Cancellation (AEC), with phantom power, 54 dB of gain and 24 dB of trim. Symetrix’ latest generation AEC provides wideband processing with tail lengths up to 250 mS, and covergence times greater that 100 dB\/S. Symetrix AEC latency is an industry low 11 mS and near zero bypassed. Each channel of AEC features discreet reference inputs and direct outputs for local reinforcement. AEC processing may be applied to any SymNet system input while still allowing the card’s inputs to be used. The inputs are electronically balanced using plug-in barrier strip connectors. Control of each input includes gain with metering, trim, mute, AEC, noise cancellation, nonlinear processing, and AGC (Automatic Gain Control).\u003c\/p\u003e\r\n\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\u003cspan\u003eWideband dedicated processing.\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan\u003eZero-latency direct outputs and discrete reference inputs per AEC channel.\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan\u003eAEC processing available to the card’s direct inputs or internally routed sources.\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan\u003e11 mS AEC latency, up to 300 mS tail length, and greater than 100 dB\/S convergence time.\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan\u003eField swappable by certified technicians.\u003c\/span\u003e\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\r\n\u003ctable style=\"width: 705px; height: 490px;\" border=\"0\"\u003e\n\u003ccolgroup\u003e\n\u003ccol\u003e \u003ccol\u003e \u003c\/colgroup\u003e\r\n\u003ctbody\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl66\"\u003eNumber of Inputs\u003c\/td\u003e\r\n\u003ctd class=\"xl67\"\u003eFour (4) acoustic echo cancellation.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eConnectors\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e3.81 mm terminal blocks.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eNominal Input Level\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e+4 dBu with 20 dB of headroom.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eMaximum Input Level\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e+23 dBu.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eMic Pre-amp Gain\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e0, 11.8, 24, 44 or 54 dB switchable with ± 24 dB trim.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eMic Pre-amp EIN\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e\u0026lt;-127 dB with 150 Ohm source impedance.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eCMRR\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e\u0026gt; 76 dB @ 1 kHz, unity gain.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eInput Impedance\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e8k Ohms balanced, 4k Ohms unbalanced.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003ePhantom Power\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e+20 VDC @ 10 mA maximum.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eA\/D Dynamic Range\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e\u0026lt; 115 dB, A-weighted.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eA\/D Latency\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e0.28 mS (direct), 11 mS (AEC enabled).\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eA\/D THD + Noise\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e\u0026lt;-94 dB, unweighted.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl68\"\u003eTail Length\u003c\/td\u003e\r\n\u003ctd class=\"xl69\"\u003e\u0026gt; 250 mS.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl70\"\u003eConvergence Time\u003c\/td\u003e\r\n\u003ctd class=\"xl71\"\u003e\u0026gt; 100 dB\/S.\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl65\"\u003e\r\n\u003cdiv\u003e\r\n\u003cdiv\u003eMechanical Data\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/td\u003e\r\n\u003ctd\u003e \u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd class=\"xl66\"\u003eShipping Weight\u003c\/td\u003e\r\n\u003ctd class=\"xl67\"\u003e1 lbs.
